chore(release): patch v1.89.0-rc.2 with batch-file auth, CrowdStrike AIDR, Mantle SigV4, NetApp streaming-cost fix, and team-scoped Datadog toward v1.89.0-rc.3 (#30179)
* fix(proxy): authorize batch files using upload target_model_names (LIT-3593) (#30009)

* fix(proxy): authorize batch files using upload target_model_names (LIT-3593)

After replace_model_in_jsonl, body.model is a stripped provider id. Reverse-mapping it via resolve_model_name_from_model_id is first-match on model_list and caused false 403s when multiple deployments share the same stripped name. Use target_model_names from the unified file id instead.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(proxy): restore resolve_model_name_from_model_id for JSONL fallback path (LIT-3593)

Restores the reverse-lookup for the JSONL body.model fallback path so that
legacy/pre-target_model_names managed files still map stripped provider IDs
back to proxy aliases before auth. Also cleans up redundant `or None`.

* Revert "fix(proxy): restore resolve_model_name_from_model_id for JSONL fallback path (LIT-3593)"

(cherry picked from commit 2cd7e87485)

* feat(guardrails): capture user and model metadata in CrowdStrike AIDR

(cherry picked from commit 6fc715c5bd)

* fix(guardrails): read CrowdStrike AIDR identity from both metadata bags (#29991)

Capture user_id and extra_info from metadata or litellm_metadata. The single-bag read dropped identity whenever a request carried a present litellm_metadata field (null or a user-supplied dict), since /chat/completions routes the authenticated identity into metadata while the guardrail read litellm_metadata first

(cherry picked from commit 1bbaf1c39d)

* feat(bedrock_mantle): add SigV4/IAM auth to Responses API route (#29788)

Applied as the squash diff of PR #29788 (head 9800b2f17c), which landed
upstream inside the litellm_oss_staging_080626 sync (32c88ca74f, #29932)
and has no standalone commit to cherry-pick. The rc line already carries
the prerequisite #29490 Responses route via the 040626 sync.

* fix: completion_cost AttributeError on streaming Anthropic web_search responses (#26153) (#27346)

Cherry-picked from staging squash 4a3860df1f.

The rc line predates the Usage.__init__ server_tool_use dict->ServerToolUse
coercion that staging carries (it landed via the squashed OSS sync #29932 /
32c88ca74f, not as a standalone commit). The calculate_usage
Usage(**returned_usage.model_dump()) round-trip re-serializes server_tool_use
to a plain dict, so without that coercion the rebuilt usage holds a dict and the
regression test asserting a ServerToolUse type fails. Restored the coercion in
litellm/types/utils.py to satisfy the prerequisite -- it matches #27346's own
first commit (coerce server_tool_use dict to ServerToolUse in Usage.__init__),
which was dropped from the squash only because staging already carried it.

* feat(datadog): add team-scoped Datadog callback support (#29947)

Cherry-picked from the PR head 9c049daa1b (single-commit PR, merged to
litellm_oss_branch). Applied cleanly; no conflicts.

Note: black --check in this worktree flags pre-existing multi-line string
formatting in litellm_core_utils/litellm_logging.py (lines ~1006-1050) that is
already present on the patch/v1.89.0-rc.1 base and is untouched by this pick --
left as-is to avoid reformatting unrelated lines.

Title: fix(proxy): resolve vector store file list credentials from team deployments (#29739)
* fix(proxy): resolve vector store file list credentials from team deployments

GET /v1/vector_stores/{id}/files now uses the same router credential routing as POST, including JWT team model hints and wildcard model selectors, so list requests no longer call OpenAI with Bearer None.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(proxy): authorize model hints and fix credential routing for vector store file list

Resolves three review findings on the vector store file list path.

Authorize user-controlled model hints (?model= query param and the
x-litellm-model header) against the key's and team's allowed models via
can_key_call_model / _can_object_call_model before any deployment
credentials are resolved, closing a model access bypass where a normal
key could file-list using a restricted deployment's provider credentials.

Run the managed vector store registry resolution before the model routing
hint so the managed store sets the routing model first; the hint resolver
then selects credentials matching that model instead of a team fallback
deployment, avoiding a credential/model mismatch across deployments.

Skip team-fallback deployments whose provider cannot be determined instead
of treating them as OpenAI, so a deployment without an explicit
custom_llm_provider or "openai/" prefix no longer has its credentials
injected.

* fix(proxy): enforce vector store file model auth

Ensure vector store file listing routes authorize explicit and inferred model routing before resolving deployment credentials.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(proxy): type guard vector store model hints

Keep vector store model hint authorization typed to string-only values so static checks pass.

feat(proxy): hot-reload .env in dev when running with --reload (#29783)
* feat(proxy): hot-reload .env in dev when running with --reload

The --reload watcher already restarts the worker on *.py and --config YAML
edits, but .env was unwatched, so changing a key there did nothing until a
manual restart. Add .env to the uvicorn reload_includes (and to the
StatReload monkeypatch, which ignores reload_includes) so an edit triggers a
worker restart.

A reloaded worker is a fresh process that inherits the reloader's
environment, so load_dotenv(override=False) would keep serving the stale
inherited value for any key already in the environment. The CLI now exports
LITELLM_DEV_ENV_HOT_RELOAD when --reload is set, and litellm/__init__.py
reads it to load .env with override=True only on that dev path, leaving
normal startup precedence untouched.

* feat(proxy): warn that --reload makes .env override shell env vars

When --reload is active, worker processes re-read .env with override=True, so
.env values win over shell-exported environment variables. Surface this dotenv
precedence change with a startup warning so a developer who relies on a
shell-exported override is not silently surprised.

* fix(proxy): type reload helper paths as Optional[str] to satisfy mypy

* fix(proxy): watch the cwd .env in both reload backends for parity

WatchFiles only watches cwd (and the --config dir) for .env, while the
StatReload fallback used find_dotenv(usecwd=True), which walks up to a
parent-dir .env that WatchFiles never sees. Point StatReload at the same
cwd .env so the two reload backends react to the same file.

fix(proxy): drop deleted team BYOK model name from team.models (#29820)
Deleting a team-scoped BYOK model left its public name in team.models, so /models
with a team key kept listing the now-deleted "ghost" model. delete_model stripped
team.models using only litellm_modeltable alias lookups, but models added via
/model/new with a team_id never create an alias row; their public name lives only
in team.models and model_info.team_public_model_name, so it was never removed. The
team cache was also left stale because the delete path skipped _refresh_cached_team.

The cleanup now keys off team_public_model_name (falling back to alias keys), runs
after the deployment row is deleted, and strips a public name only when no remaining
team deployment still backs it, so a load-balanced replica is not revoked and
concurrent deletes cannot leave a ghost. The updated team row is refreshed in cache
so /models reflects the change immediately

fix(jwt): use resolved DB user_id for spend on legacy email match (#29217)
* fix(jwt): attribute spend to resolved DB user_id on email/sso fuzzy match

When user_id_upsert is enabled with JWT auth and a pre-migration user row
exists whose user_email matches the JWT email but whose user_id is a UUID,
get_user_object resolves the legacy row via fuzzy lookup, but the JWT-claim
user_id (the email) still flowed into team-membership lookup,
JWTAuthBuilderResult.user_id, UserAPIKeyAuth and the spend tables. Spend was
orphaned under a phantom email id; /user/info and the Usage page showed $0
for the legacy user (GH #26789).

Treat the resolved user_object as the source of truth: add
_canonical_user_id_from_db, rebind inside get_objects, and return
effective_user_id so auth_builder unpacks it without adding statements.

Fixes #26789

test(google): add google-genai SDK proxy integration tests (#29781)
* test(google): add google-genai SDK proxy integration tests for Gemini and Vertex

Pin google-genai in the CI dependency group and exercise streaming/non-streaming
generate_content through the LiteLLM proxy in the existing unified_google_tests suite.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(test): address Greptile review for google-genai proxy SDK tests

Restore GOOGLE_APPLICATION_CREDENTIALS after the module proxy fixture tears down,
initialize temp-file tracking on the proxy SDK base class, and skip litellm reload
for proxy_genai_sdk tests so the module-scoped proxy server stays consistent.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(test): only load Vertex credentials when keys exist for proxy SDK tests

Avoid writing empty GOOGLE_APPLICATION_CREDENTIALS temp files so Vertex tests
skip cleanly without credentials, use a session-scoped proxy fixture, and clean up
per-test credential temp files.

Co-authored-by: Cursor <cursoragent@cursor.com>

* chore(test): scope google-genai pin to unified_google_tests only

Remove google-genai from the ci dependency group and pin it in
tests/unified_google_tests/requirements.txt for local test installs.

Co-authored-by: Cursor <cursoragent@cursor.com>

* test(google): tie litellm reload skip to proxy fixture dependency

Replace the name-based reload guard with a check on whether the test
requests the google_genai_proxy_url fixture, so the skip stays correct
if the proxy SDK tests are renamed.

* fix(test): stop DatabaseURLSettings tests leaking DATABASE_URL into os.environ

The autouse env scrubber relied on monkeypatch.delenv, but apply_to_env
writes DATABASE_URL straight into os.environ, which monkeypatch never
tracks and therefore never undoes. The synthesized writer.example.com URL
leaked past the last test in this module and into proxy-infra tests that
read DATABASE_URL to decide whether to hit a real database, e.g.
test_deprecated_key_grace_period_cache_hit_path, turning an intended skip
into a ConnectError. Snapshot and restore the managed vars directly so the
original environment is reinstated regardless of how it was mutated.

* test(google): drop redundant per-test vertex credential setup

The session-scoped google_genai_proxy_url fixture already configures
GOOGLE_APPLICATION_CREDENTIALS before the proxy starts, and
_require_proxy_sdk skips when credentials are missing, so the per-test
_setup_vertex_credentials_if_needed helper and its temp-file tracking
never did any work. Remove it to keep the ABC self-contained.

* test(google): declare model_config contract on proxy SDK ABC

_skip_reason_if_credentials_missing reads self.model_config to pick the
provider, but that property was only declared on the sibling
BaseGoogleGenAITest. Make the dependency explicit by adding model_config
as an abstract property on BaseGoogleGenAIProxySDKTest so the ABC is
self-contained and a standalone subclass fails fast instead of hitting an
AttributeError.

* test(google): narrow streaming error catch to Exception

Catching BaseException in the streaming assertion swallowed
KeyboardInterrupt and SystemExit, turning a Ctrl-C into a test failure
message instead of letting pytest interrupt cleanly. Only genuine runtime
errors should be recorded as stream failures, so catch Exception.

* test(google): initialize proxy on the same loop that serves it

The proxy was initialized via asyncio.run() on the main thread, which
creates and tears down a throwaway event loop, while requests were served
on a separate loop in the worker thread. Any asyncio primitive bound to
the init loop would be unusable once serving started. Run initialize()
on the worker thread's loop right before server.serve() so setup and
request handling share a single event loop.

* test(google): drop redundant google-genai requirements pin

google-genai>=1.37.0,<2.0 is already declared in the proxy-runtime extra,
which the google_generate_content_endpoint_testing CI job installs via
uv sync --all-extras. The standalone tests/unified_google_tests/requirements.txt
duplicated that pin with a narrower ==1.37.0 specifier and was never
installed by CI, so it added a second source of truth without changing
what gets installed. Drop it and rely on the proxy-runtime extra.

* chore: revert incidental uv.lock exclude-newer bump

The google-genai ci pin was added and then dropped (it is already
provided by the proxy-runtime group), but each uv lock recomputed the
relative exclude-newer span, leaving only a timestamp bump in uv.lock.
Restore it to the base value so this test-only PR carries no lockfile
change.

* Mark xAI models retiring on 2026-05-15 (#28788)

Per https://docs.x.ai/developers/migration/may-15-retirement, xAI is
retiring the following slugs on 2026-05-15 (auto-redirect to grok-4.3
with various reasoning efforts; callers continuing to use the old slugs
will be billed at grok-4.3 pricing):

  grok-4-1-fast-reasoning{,-latest}      -> grok-4.3 (low effort)
  grok-4-1-fast-non-reasoning{,-latest}  -> grok-4.3 (none)
  grok-4-fast-reasoning                  -> grok-4.3 (low effort)
  grok-4-fast-non-reasoning              -> grok-4.3 (none)
  grok-4-0709                            -> grok-4.3 (low effort)
  grok-code-fast-1{,-0825}               -> grok-build-0.1
  grok-3                                 -> grok-4.3 (none)

Only the direct xai/ slugs are tagged; third-party hosts (azure_ai,
oci, vercel_ai_gateway, perplexity/xai) run their own schedules. The
grok-3 retirement list explicitly names only the base grok-3 slug — the
-mini / -fast / -beta / -latest variants are not listed, so they remain
untouched.

* feat(moonshot): advertise json_schema response support on live models (#29683)

litellm.responses() already routes Moonshot through the responses->chat-completions
bridge, and Moonshot honors response_format json_schema on chat completions. The
cost-map entries left supports_response_schema unset, so discovery layers that gate
on that flag dropped Moonshot from structured-output / responses listings even though
the capability works end to end.

Set supports_response_schema on the nine models currently live on api.moonshot.ai:
kimi-k2.5, kimi-k2.6, the moonshot-v1 8k/32k/128k text and vision-preview variants,
and moonshot-v1-auto. Verified against the live API that each honors json_schema and
that litellm.responses() returns schema-valid structured output through the bridge.

* chore(moonshot): mark models retired from api.moonshot.ai as deprecated (#29685)

Thirteen Moonshot/Kimi models in the cost map no longer resolve on
api.moonshot.ai (all return 404). Stamp each with its deprecation_date from
platform.kimi.ai/docs/models rather than deleting the entries, so historical
cost calculation keeps resolving the names while tooling can surface the
retirement.

Dates: kimi-thinking-preview 2025-11-11; kimi-latest and its 8k/32k/128k context
variants 2026-01-28; the kimi-k2 preview/turbo/thinking series 2026-05-25; the
moonshot-v1 -0430 snapshots use their own 2024-04-30 snapshot date (Moonshot
publishes no discontinuation date for them).

* fix(moonshot): drop temperature for reasoning models (kimi-k2.5/k2.6) (#29687)

Kimi reasoning models reject every temperature except 1; a request with
temperature=0.2 returns "invalid temperature: only 1 is allowed for this model".
litellm only clamped temperature into [0.3, 1], so any value below 1 still 400'd.

Drop the temperature param entirely for reasoning models (gated on
supports_reasoning, the same signal transform_request already uses) so the model
default is used; the non-reasoning moonshot-v1 models keep the existing clamp.

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505) (#28575)

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505)

When a Chat Completions request to a GPT-5.4+ model contains both
`tools` and `reasoning_effort`, `completion()` auto-routes through
`responses_api_bridge`. The bridge handler called
`litellm.responses()` / `litellm.aresponses()` without forwarding the
already-resolved `custom_llm_provider`, so the downstream call
re-invoked `get_llm_provider()` with `custom_llm_provider=None` and
stripped a second provider prefix from a `provider/provider/model`
deployment string.

For a deployment configured as `openai/openai/openai/gpt-5.5`,
the bridge flow sent `openai/gpt-5.5` to the upstream API instead of
the correct `openai/openai/gpt-5.5`. Upstream APIs that enforce
model-name allow-lists rejected this as `key_model_access_denied`.

Fix: pass the locally-resolved `custom_llm_provider` into both the
sync `responses()` and async `aresponses()` calls so the downstream
`_resolve_model_provider_for_responses` sees an explicit provider
and skips the second prefix-strip.

New regression test
`tests/test_litellm/completion_extras/test_responses_bridge_provider_propagation.py`
pins both call sites: each must forward `custom_llm_provider`.

* fix(28505): set custom_llm_provider on request_data instead of as duplicate kwarg

Greptile flagged that the previous patch passed custom_llm_provider as an
explicit kwarg to responses()/aresponses() while request_data already
carried it via the spread of sanitized_litellm_params, which would raise
TypeError: got multiple values for keyword argument on every real bridge
call.

Switches to assigning request_data['custom_llm_provider'] before the call
so the resolved provider wins over whatever sanitized_litellm_params spread
in, without duplicating the kwarg.

Updates the regression test to seed request_data with a sentinel
custom_llm_provider so it actually exercises the overwrite path (the
previous test mocked transform_request with a minimal dict and never hit
the conflict).

* chore: trigger shin-agent re-eval on retargeted staging base

* chore: trigger shin-agent re-eval against updated Greptile state

* Add jp. Bedrock cross-region inference profile for claude-opus-4-7

AWS Bedrock documents jp.anthropic.claude-opus-4-7 alongside the
existing us./eu./au./global. profiles for Claude Opus 4.7
(ap-northeast-1 Tokyo / ap-northeast-3 Osaka), but the entry is
missing from model_prices_and_context_window.json. Tokyo-region
users currently get an "unknown model" error when routing through
the JP geo profile.

Adds the entry to both the canonical file and the bundled backup,
mirroring the recent pattern for sonnet-4-6 (#27831). Pricing matches
the other regional profiles (10% premium over base/global).

Regression test pins all six documented profiles (base, global, us, eu,
au, jp) and asserts pricing parity between jp. and au. variants.

* feat(soniox): add soniox audio transcription integration (#29508)

* feat(openmeter): add OPENMETER_TRUST_REQUEST_USER to prevent forged attribution (#29650)

The OpenMeter callback resolves the CloudEvent subject from kwargs["user"]
first, then falls back to the key-bound user_api_key_user_id. For
multi-tenant proxy deployments, a client can set `"user": "..."` in the
request body and cause their usage to be attributed to that arbitrary
string — a billing-attribution forgery risk.

Adds OPENMETER_TRUST_REQUEST_USER env var (default "true" for backward
compatibility). When set to "false", the request-supplied `user` field is
ignored and the subject is resolved solely from user_api_key_user_id.

Matches the existing env-var-driven config pattern in this file
(OPENMETER_API_KEY, OPENMETER_API_ENDPOINT, OPENMETER_EVENT_TYPE).

  endswith("/v1/search") check, so a custom base like ".../v1/search/"
  doesn't become ".../v1/search/v1/search".
- transform_search_request: .lower() country before sending, matching
  Tavily's convention so callers using the unified spec form ("US") get
  consistent behavior across providers.
- Tests: replace direct os.environ writes with an autouse monkeypatch
  fixture so YOUCOM_API_KEY is set per-test and removed afterwards.
  The missing-key test now uses monkeypatch.delenv. New test asserts the
  trailing-slash normalization above.

Reverts the ARCHITECTURE.md / example yaml edits per the reviewer note
that documentation changes belong in the litellm-docs repo.

* support keyless free tier (api.you.com/v1/agents/search) as default

You.com offers an IP-throttled keyless endpoint that returns the same
response shape as the keyed one (~100 queries/day, no signup). This is a
significant onboarding lever - mirrors the keyless DuckDuckGo/SearXNG
providers already in the search_tools registry.

Behavior:
- YOUCOM_API_KEY set        -> keyed:  POST https://ydc-index.io/v1/search
                                       (X-API-Key header)
- no key                    -> free:   POST https://api.you.com/v1/agents/search
                                       (no auth)
- YOUCOM_API_BASE override  -> honored as-is

Tests:
- New: test_you_com_search_keyless_free_tier - asserts URL + absence of
  X-API-Key when no key is configured.
- New: test_you_com_search_validate_environment_keyless - asserts the
  config no longer raises when the key is absent.
- Removed: test_you_com_search_raises_without_api_key (the precondition
  no longer holds).
- Existing payload/domain-filter/etc tests still cover keyed mode via
  the autouse YOUCOM_API_KEY fixture.

Verified both endpoints accept POST + return identical JSON shape:
  results.web[] / results.news[] with title, url, snippets, description,
  page_age.

* register you_com in provider_endpoints_support.json

Adding `litellm/llms/you_com/` requires a corresponding entry in
provider_endpoints_support.json or the
code-quality/check_provider_folders_documented CI check fails.

Follows the compact tavily/serper pattern - endpoints: { search: true }.
Local run of the check now reports "All 114 provider folders are documented".

* move tests under tests/test_litellm/llms/ so CI exercises them

The litellm CI workflows scope unit tests to `tests/test_litellm/...`
(see test-unit-llm-providers.yml: `tests/test_litellm/llms` path), so
tests living under `tests/search_tests/` are never run in CI - which is
why codecov reports 0% patch coverage for the new adapter even though
the unit tests exist and pass locally.

Move test_you_com_search.py into `tests/test_litellm/llms/you_com/` so
the test-unit-llm-providers job picks it up. 7/7 tests still pass at
the new location.

(Sibling search-only providers - tavily, exa_ai, brave, etc. - still
live only in `tests/search_tests/` and would benefit from the same
move, but that is out of scope for this PR.)

* fix(you_com): pin Accept-Encoding: identity to dodge keyless gzip bug

The keyless free-tier endpoint (api.you.com/v1/agents/search) advertises
Content-Encoding: gzip but returns a body that httpx's decoder rejects
with `zlib.error: Error -3 while decompressing data: incorrect header
check`, surfacing as litellm.APIConnectionError in user code. curl works
because it doesn't request compression by default.

Pin Accept-Encoding: identity in validate_environment so the upstream
server skips compression entirely. Harmless on the keyed endpoint
(ydc-index.io/v1/search) which negotiates content-encoding correctly.

The header uses setdefault so a caller-supplied Accept-Encoding still
takes precedence. (Server-side bug has been flagged to the You.com team
separately - once fixed there, this workaround can be removed.)

New unit test: test_you_com_search_pins_identity_accept_encoding.

* fix: address greptile and veria review feedback

- langfuse: guard httpx_client injection behind version check (>= 2.7.3)
- soniox: propagate audio_transcription_duration in _hidden_params for spend tracking
- soniox: give SONIOX_API_BASE env var priority over caller-supplied api_base
- mcp: replace CancelledError catch with asyncio.wait_for + TimeoutError

* chore(mcp): add migration for per-server timeout column

* fix(test): add tool_use_system_prompt_tokens to model prices schema validator

* fix: mcp timeout test uses real asyncio.wait_for timeout; you_com get_complete_url respects resolved api_key

* fix: forward resolved api_key into you_com endpoint selection and apply timeout to soniox polling GETs

The search flow resolves api_key in validate_environment but never passed it
into get_complete_url, so a programmatic api_key (with no YOUCOM_API_KEY in the
env) set the X-API-Key header yet still selected the keyless free-tier endpoint.
Forward api_key through both the search entrypoint and the http handler so the
keyed endpoint is chosen.

HTTPHandler.get/AsyncHTTPHandler.get had no timeout parameter, so the Soniox
poll and transcript-fetch GETs silently used the client global default instead
of the caller timeout. Add a per-request timeout to get() and forward the
configured timeout from the Soniox handler.

* fix(soniox): price stt-async-v4 per second so transcriptions are billed

The handler stores audio_transcription_duration in _hidden_params, but the
model carried only token cost fields and the response has no token usage, so
the transcription cost path fell through to cost_per_second and returned $0.
An authenticated caller could transcribe Soniox audio without decrementing
their budget. Switch the entry to output_cost_per_second at Soniox's published
$0.10/hour async rate so the stored duration produces a real charge.

* fix(langfuse): use a dedicated httpx client for the SDK injection

The httpx_client handed to the Langfuse SDK came from _get_httpx_client(),
which returns LiteLLM's globally cached HTTPHandler. If Langfuse closed that
client on teardown it would invalidate the shared client used by every other
LiteLLM HTTP call. Build a dedicated httpx.Client instead, still resolving SSL
verification and client certificate from LiteLLM's configuration.

* fix(soniox): prefer caller-supplied api_base over SONIOX_API_BASE env var

* fix(cohere): support max_completion_tokens on cohere v2 chat (default route) (#29779)

* fix(cohere): support max_completion_tokens on cohere v2 chat

The default cohere_chat route resolves to CohereV2ChatConfig, which did not
list or map max_completion_tokens, so get_optional_params raised
UnsupportedParamsError for the standard OpenAI parameter (the modern
replacement for the deprecated max_tokens). The v1 config already maps it to
cohere's max_tokens; mirror that in v2 and add v2 regression tests.

* fix(cohere): make max_completion_tokens take precedence over max_tokens on v2

When both max_tokens and max_completion_tokens are supplied, prefer
max_completion_tokens explicitly rather than relying on dict iteration order,
and cover both orderings with a regression test.

fix(auth): expand all-team-models sentinel in can_key_call_model for batch validation (#29746)
* fix(auth): expand all-team-models sentinel in can_key_call_model

Keys with models=["all-team-models"] were denied during batch JSONL
model validation because can_key_call_model matched the literal string
against the model name. Add _resolve_key_models_for_auth_check to
expand the sentinel to team_models before the check, consistent with
get_key_models in model_checks.py and the completion-route bypass.

Co-authored-by: Cursor <cursoragent@cursor.com>

* docs(auth): document empty team_models unrestricted access behavior; add regression test

Adds a docstring note to _resolve_key_models_for_auth_check explaining that
when team_models is empty, all-team-models resolves to [] which is treated as
unrestricted access (consistent with get_key_models behavior on other auth
paths). Adds a test to lock in this behavior.

* fix(auth): deny all-team-models access when key has no team_id

A key configured with models=["all-team-models"] but no team_id could
previously resolve to an empty allowlist, which _check_model_access_helper
treats as unrestricted access. Now the sentinel is only expanded when
team_id is set; otherwise the unresolved sentinel stays in the model list
and causes a deny (no real model name matches it). Same fix applied to
get_key_models in model_checks.py for consistency across batch and
non-batch auth paths.

Support OAuth M2M for Databricks Apps A2A agents (#29586)
* Add OAuth M2M support for A2A agents targeting Databricks Apps

Databricks App endpoints reject static bearer tokens and require a
short-lived OAuth token minted via the workspace OIDC token endpoint.
A2A agents could previously only authenticate outbound with static_headers
or client header passthrough, so Databricks App agents could not be
registered.

Agents configured with a databricks_oauth block in litellm_params now mint
and cache a client_credentials token and attach it as the outbound
Authorization header on both message/send and message/stream calls,
overriding any statically configured Authorization.

* Add tests covering Databricks App OAuth token error paths

Cover the HTTP status error, transport error, non-object JSON body, and
invalid expires_in fallback branches in the token cache so the failure
handling is locked in by regression tests.

* Harden Databricks App OAuth token cache

Cap the cache TTL at the token's own lifetime so a token whose validity is
shorter than the refresh buffer is never cached and served stale; include a
digest of client_secret in the cache key so a rotated secret mints a fresh
token instead of reusing the old one; and prune the per-key lock when its
cached token is evicted so the lock map stays bounded by the live key set.

* Clear per-key locks on Databricks OAuth cache flush

* fix(a2a/databricks): mint OAuth token via Basic auth header, not unsupported auth= kwarg

litellm's AsyncHTTPHandler.post (what get_async_httpx_client returns) has no
auth parameter, so minting a Databricks App OAuth token raised
"AsyncHTTPHandler.post() got an unexpected keyword argument 'auth'" before any
network call ever left the proxy, breaking the feature end to end. The handler
also calls raise_for_status() internally and re-raises a MaskedHTTPStatusError
(a subclass of httpx.HTTPStatusError), so the explicit raise_for_status() after
post() was dead code.

Build the HTTP Basic Authorization header by hand and pass it via headers, which
is what the Databricks workspace OIDC token endpoint documents for client
authentication. The token-cache tests now model the real handler contract with
create_autospec so the rejected auth= signature is enforced; the previous mocks
accepted any kwargs and silently hid the bug.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* Prune Databricks OAuth lock on the short-lived-token path

When expires_in is below the refresh buffer the token is intentionally
not cached, so _remove_key never runs for that key and the per-key lock
created by _get_lock leaked permanently. Drop the lock in that branch so
_locks stays bounded by the live key set, and assert the cleanup in the
short-lived-token test

* Gate A2A Databricks OAuth on the databricks_oauth block at the call site

Make the gating explicit where the header is applied so it is clear that only
agents configured with a databricks_oauth block enter the OAuth path; every
other agent is left untouched. Add a regression test asserting a non-Databricks
agent never invokes the token resolver.

fix(proxy/hooks): populate llm_provider on internal rate-limit errors (#27707)
* feat(proxy/hooks): add ProxyHTTPRateLimitError + provider resolver

Introduces a small helper layer used by every proxy-side rate-limit
hook so that the 429 they raise carries a populated llm_provider /
model — instead of an empty exception.llm_provider that downstream
loggers (Prometheus failure metric, observability callbacks) read as
'no provider attribution'.

ProxyHTTPRateLimitError inherits from both fastapi.HTTPException
(so the proxy server still renders it as a 429) and
litellm.exceptions.RateLimitError (so isinstance checks and
PrometheusLogger._get_exception_class_name pick up llm_provider).
We deliberately don't call RateLimitError.__init__ — it constructs
an httpx.Response we don't need and would just add failure surface;
attribute parity is what downstream consumers care about.

resolve_llm_provider_for_rate_limit() wraps litellm.get_llm_provider
defensively. Internal limiter hooks fire from async_pre_call_hook —
well before get_llm_provider runs anywhere else in the request
lifecycle — so we have to call it ourselves at raise time. If the
model is missing or unparseable (alias, router-only model) we fall
back to llm_provider='litellm_proxy' rather than letting a second
exception leak out and break the request path.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* fix(proxy/hooks): populate llm_provider on parallel-request 429s

Both v1 and v3 parallel-request limiters fired bare HTTPException(429)
from inside async_pre_call_hook. The downstream Prometheus failure
metric reads exception.llm_provider via _get_exception_class_name —
the empty value showed up as exception_class='HTTPException' and
left model_id='None' on the time series.

Threads requested_model through every raise site in:

* parallel_request_limiter.py:
  - check_key_in_limits (the per-key/per-model/per-user/per-team/
    per-customer over-limit path)
  - raise_rate_limit_error (zero-limit + global_max_parallel_requests
    paths) — now takes an optional requested_model kwarg
* parallel_request_limiter_v3.py:
  - _handle_rate_limit_error (the OVER_LIMIT translator), called
    from both the should_rate_limit pre-check and the TPM
    reservation path

Resolved via resolve_llm_provider_for_rate_limit so unknown / missing
models silently fall back to llm_provider='litellm_proxy' instead of
breaking the request path with a second exception.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* fix(proxy/hooks): populate llm_provider on dynamic-rate-limit 429s

Same plumbing change as the parallel limiters, applied to both
dynamic_rate_limiter (v1) and dynamic_rate_limiter_v3:

* v1: TPM-zero and RPM-zero paths in async_pre_call_hook now resolve
  data['model'] -> (model, llm_provider) once and pass it into both
  raises.
* v3: All three raise sites in _check_rate_limits — the
  model_saturation_check enforced raise, the priority_model
  enforced raise, and the fail-closed unknown-descriptor branch —
  now attribute the 429 to the actual provider.

Falls back to llm_provider='litellm_proxy' when the model can't be
resolved.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* fix(proxy/hooks): populate llm_provider on batch-rate-limit 429s

batch_rate_limiter._raise_rate_limit_error now takes a
requested_model kwarg threaded from data['model'] in
_check_and_increment_batch_counters. The batch-creation 429 is what
gets raised when the input file's tokens/requests count would push
the per-key TPM/RPM window over its limit.

Co-authored-by: Mateo Wang <mateo-berri@users.noreply.github.com>

* fix(proxy/hooks): populate llm_provider on budget/iterations 429s

Final batch of internal raise sites — the user/session-budget and
max-iterations hooks. Same pattern: resolve data['model'] once at
raise time, attach to ProxyHTTPRateLimitError so Prometheus and
observability callbacks can attribute the 429.

Hooks updated:
* max_budget_limiter (per-user max_budget exceeded)
* max_iterations_limiter (per-session agent iteration cap)
* max_budget_per_session_limiter (per-session dollar cap)

All three fall back to llm_provider='litellm_proxy' when data['model']
is missing or unparseable. Drops the now-unused HTTPException import
from each module.

* test(proxy/hooks): pin provider field on internal rate-limit 429s

Regression coverage for the 'provider field missing' bug across every
proxy-side rate-limit hook + the helper layer:

* ProxyHTTPRateLimitError class shape (HTTPException + RateLimitError,
  dict-detail stringification, None-provider normalization).
* resolve_llm_provider_for_rate_limit happy paths
  (gpt-4o-mini, anthropic/..., bedrock/...) plus all three fallback
  branches (None, '', unknown name) plus a 'get_llm_provider raises'
  case that asserts we swallow the secondary exception.
* For each limiter (parallel v1/v3, dynamic v1/v3, batch,
  max_budget, max_iterations, max_budget_per_session): assert the
  raised exception is a RateLimitError carrying the resolved
  model + llm_provider, and a sibling test that asserts the
  fallback path returns 'litellm_proxy' without leaking a second
  exception.
* Two PrometheusLogger._get_exception_class_name pins so the
  Prometheus failure metric label flips from 'HTTPException' to
  'Openai.ProxyHTTPRateLimitError' (or 'Litellm_proxy.*' on
  fallback) — that's what dashboards consume.

* perf(proxy/hooks): defer provider resolution to over-limit branches

* fix: use error_message in raise_rate_limit_error to avoid literal 'None' in detail

* Consolidate rate_limiter_utils imports in dynamic_rate_limiter

* fix(proxy): set num_retries/max_retries on ProxyHTTPRateLimitError

ProxyHTTPRateLimitError inherits from RateLimitError but did not call
RateLimitError.__init__, so num_retries/max_retries were never set.
When Starlette's HTTPException lacks __str__, MRO falls through to
RateLimitError.__str__, which unconditionally reads these attributes
and raises AttributeError during logging/traceback formatting.
Initialize them to None defensively.

* fix(mypy): silence base-class status_code conflict on ProxyHTTPRateLimitError

HTTPException declares 'status_code: int' while openai.RateLimitError
(via APIStatusError) declares 'status_code: Literal[429] = 429'. Mypy
flags the multi-base override as [misc] in CI lint. The runtime semantics
are fine (we set self.status_code in __init__), so silence the
class-level annotation conflict with a targeted ignore.

[internal copy of #29511] feat(guardrails): add sensitive data routing to on-premise models (#29531)
* feat(guardrails): add sensitive data routing to on-premise models

When a guardrail detects sensitive data, route to an on-premise model
instead of blocking or redacting. All subsequent requests in that
session continue routing to the same model (sticky routing).

New config options for guardrails:
- on_sensitive_data: 'block' (default) or 'route'
- sensitive_data_route_to_model: target model for rerouting
- sticky_session_routing: persist routing for session (default: true)

New exception SensitiveDataRouteException triggers rerouting when raised
by guardrails. The proxy catches it, stores the routing decision in
cache, and modifies the request's model field.

New hook _PROXY_SensitiveDataRoutingHandler checks incoming requests
against cached routing decisions and applies sticky routing.

https://claude.ai/code/session_01SQd4isBa3UyouRoGVou9dK

* fix: black formatting for custom_guardrail.py

https://claude.ai/code/session_01SQd4isBa3UyouRoGVou9dK

* test: improve test coverage for sensitive data routing feature

Add additional tests for:
- Cache key format and TTL constants
- Session ID extraction from multiple locations
- Custom guardrail initialization with routing config
- Exception string representation and custom messages
- Redis cache paths including fallback behavior
- Edge cases in pre-call hook

https://claude.ai/code/session_01SQd4isBa3UyouRoGVou9dK

* fix: use correct GuardrailRaisedException parameters

Replace invalid 'source' parameter with 'guardrail_name' to match
the exception's actual signature.

https://claude.ai/code/session_01SQd4isBa3UyouRoGVou9dK

* test: move sensitive data routing tests to hooks directory

Move test file to align with source code structure.

https://claude.ai/code/session_01SQd4isBa3UyouRoGVou9dK

* fix(guardrails): honor sticky_session_routing flag and scope session routing per API key

Propagate sticky_session_routing through SensitiveDataRouteException so a
guardrail configured with sticky_session_routing=False reroutes only the
triggering request without persisting a session override. Scope the routing
cache key to the requesting API key so sessions from different tenants cannot
collide, and warn when sticky routing is requested but the hook is not
registered.

* refactor(guardrails): dedupe session-id extraction and drop redundant import

Extract the shared session-id lookup into get_session_id_from_request_data
so the sensitive-data routing hook and CustomGuardrail no longer keep two
identical copies of the logic. Remove the redundant local import of
GuardrailRaisedException in handle_sensitive_data_detection, and document
that detection_info is surfaced in request metadata and logs so it must not
carry raw sensitive values.

* fix(guardrails): guard None user_api_key_dict in sensitive data route handler

* fix(responses): send application/json Content-Type on responses DELETE

OpenAI's responses DELETE endpoint now rejects requests that arrive without
a Content-Type header, defaulting them to application/octet-stream and
returning 'Unsupported content type: application/octet-stream'. The delete
handler sent no body and therefore no Content-Type, so the request failed.
Declare application/json on the delete request, matching the OpenAI SDK.

* fix(guardrails): backfill in-memory cache after redis hit in sensitive data routing

When _get_routed_model resolves a routing override from Redis it now also
populates the local in-memory cache. Without the write-back, a non-writing
instance that only ever reads from Redis would lose the sticky routing
decision the moment Redis became unavailable, silently reverting sensitive
sessions to the default model.

* fix(guardrails): scope sticky sensitive-data routing to JWT principal

Keyless auth (JWT and similar) has no api_key, so every such caller shared
the "default" cache namespace. One authenticated user could reuse another
user's session_id, trip the guardrail, and silently force the other user's
subsequent requests onto the cached on-prem model for the TTL.

Resolve the routing tenant from the api_key when present, otherwise from a
stable principal built from the user/team/org identity, before reading or
writing the session route.

* fix(guardrails): require route target model when on_sensitive_data='route'

* fix(guardrails): mark user_api_key_dict Optional in sensitive-data route handler

* fix(guardrails): use remaining redis ttl for local backfill and str env default

* fix(guardrails): graceful block when routing configured but no session_id

handle_sensitive_data_detection promised to raise only SensitiveDataRouteException
or GuardrailRaisedException, but when routing was configured and the request had no
session_id it let a ValueError from raise_sensitive_data_route_exception propagate,
surfacing as an HTTP 500 instead of a block. Fall back to a graceful block in that
case so the documented contract holds.

* fix(guardrails): run remaining guardrails after sensitive-data reroute

Defer the SensitiveDataRouteException until every guardrail in the
pre-call loop has run, so downstream security guardrails are no longer
skipped when an earlier guardrail triggers routing. The first reroute
wins and a later guardrail that blocks still propagates.

Also normalize on_sensitive_data to lowercase like sibling on_* config
fields so case-insensitive values are accepted.

* fix(guardrails): classify sensitive-data reroute as guardrail intervention

* fix(guardrails): record sensitive-data reroute as prometheus intervention not error

* fix(guardrails): record service span for routing guardrail and move case-normalizer to base params

Drop the early continue so a guardrail that signals sensitive-data routing still
emits its PROXY_PRE_CALL service span like every other callback.

Move the lowercase normalizer onto BaseLitellmParams so on_sensitive_data is
normalized consistently when BaseLitellmParams is constructed directly, matching
the cross-field route->model validator that already lives on the base.

fix(proxy): stop team BYOK model name corruption on model edit (#29731)
* fix(proxy): stop team model name corruption on edit (#28382) (#29001)

Team-scoped ("Team-BYOK") models store an internal routing key
model_name_{team_id}_{uuid} in the model_name column and the user-facing
name in model_info.team_public_model_name. The internal name leaked into
/v1, /v2, and /model/info responses; the dashboard bound its edit form to
it, so any non-rename save (e.g. a TPM tweak) PATCHed the internal name
back. The update path then treated it as a rename, overwriting
team_public_model_name and rewriting the team's models[] ACL with the
mangled string -- breaking team key calls with team_model_access_denied.

Two-layer fix:

- Read path (root cause): add _translate_model_name_for_response and apply
  it in model_info_v2 and _get_proxy_model_info so /v1, /v2, and
  /model/info surface the public name for team-scoped rows. The DB column
  and router index keep the internal name as the routing key; this is a
  presentation-layer swap on a shallow copy (never mutates input).

- Write path (defense in depth): harden _get_public_model_name so a value
  matching the internal shape, or a no-op against the current DB column,
  is never treated as a rename -- for both the top-level model_name and an
  explicit model_info.team_public_model_name.

Tests: regression for the reported scenario, full branch coverage of
_get_public_model_name, two internal-shape guard cases, an end-to-end
PATCH through _update_team_model_in_db (asserts the team ACL is untouched),
and four response-translation cases. 60 passed (model management),
181 passed (proxy server).

* fix(ui): key Agent Builder agent selection on model_info.id (#29729)

* fix(ui): key Agent Builder agent selection on model_info.id

Once team-scoped BYOK models can share a public name (the backend now
returns the public name on /model/info instead of the internal routing
key), selecting agents by model_name collides. Key selection, create,
update and delete on the stable model_info.id instead, falling back to
model_name only for config-defined agents that have no id.

* fix(ui): add name-match fallback to post-create agent selection

If the just-created agent's id is not yet present in the re-fetched
list, try matching by name before falling back to the first agent.

Litellm jwt mapping virtualkeys (#28510)
* restore an explicit no-match policy

* fix(jwt): fix AUTO_REGISTER sentinel bypass, race condition, and inline import comment

- AUTO_REGISTER now evicts stale __NO_MAPPING__ sentinel instead of silently
  returning None when cached under a prior fallback_team_mapping config
- Race condition in _auto_register_jwt_mapping: catch P2002 unique-constraint
  violation on concurrent creates, fetch the winning mapping, proceed cleanly
- Added comment on inline generate_key_helper_fn import explaining the circular
  dependency (key_management_endpoints imports user_api_key_auth at line 51)
- 3 new tests: stale sentinel eviction, race condition winner fallback, and the
  existing auto_register happy path

* fix(jwt): cache __NO_MAPPING__ sentinel before raising 403 in REJECT mode

REJECT mode was raising HTTPException immediately on a DB miss without writing
the __NO_MAPPING__ sentinel, causing every subsequent rejected request to
re-query the DB. Write the sentinel first so repeated rejections are served
from cache within virtual_key_mapping_cache_ttl.

Adds test asserting DB is not hit on the second reject after a cache-warm miss.

* fix(jwt): enforce no-match policy when prisma_client is None

The early `if prisma_client is None: return None` guard ran before the
no-match policy check, silently bypassing REJECT and AUTO_REGISTER — every
JWT client fell through to team auth regardless of configuration.

Fix: treat prisma_client=None as a definitive DB miss and fall through to the
same policy block as a real miss. REJECT now raises 403, AUTO_REGISTER raises
500 with a clear message (can't create keys without a DB), FALLBACK_TEAM_MAPPING
returns None unchanged.

Adds three tests: REJECT/403 with no DB, FALLBACK returns None with no DB,
AUTO_REGISTER/500 with no DB.

* fix(jwt): consistent AUTO_REGISTER on cached sentinel; clean up race orphans

Addresses Greptile review on PR #25570 cherry-pick.

1. Inconsistent AUTO_REGISTER when __NO_MAPPING__ sentinel is cached:
   The cached-sentinel branch silently returned None when prisma_client was
   None, while the fresh path raised HTTP 500 under the same config. Same
   request, different access-control outcome depending on cache state. Both
   paths now raise the same 500.

2. Orphaned virtual keys from race-condition losers:
   On unique-constraint conflict, generate_key_helper_fn had already persisted
   an unrestricted virtual key in LiteLLM_VerificationToken with the cleartext
   in request memory. Under sustained concurrency these accumulated
   indefinitely. The loser now deletes its orphan before falling back to the
   winner's mapping; failure to delete is logged but does not fail the request.

Also corrects a latent FK bug surfaced while fixing #2: the mapping row was
storing the plaintext key in LiteLLM_JWTKeyMapping.token, but that column FKs
to the hashed LiteLLM_VerificationToken.token — now hashed at the call site.

Tests:
- updated test_auto_register_creates_key_and_mapping to assert the hashed
  token is stored, not the plaintext
- updated test_auto_register_race_condition_unique_conflict to assert the
  orphan is deleted with the correct hashed token
- added test_auto_register_raises_500_when_sentinel_cached_and_no_db
- added test_auto_register_race_conflict_tolerates_delete_failure

* fix(jwt): close REJECT bypass when JWT omits the configured claim field

A JWT presented without the configured `virtual_key_claim_field` previously
returned None at the `claim_value is None` guard before the
`unregistered_jwt_client_behavior` check ran. A caller who knows the configured
claim-field name could bypass REJECT by simply omitting that field and falling
through to team-based JWT auth.

Apply the no-match policy on a missing claim:
  - REJECT          → 403
  - AUTO_REGISTER   → 403 (no stable identity to map; refuse rather than
                     create a sentinel-keyed record)
  - FALLBACK_TEAM_MAPPING → return None (unchanged, backward-compatible)

Adds three tests covering each branch of the missing-claim path.

* fix(jwt): AUTO_REGISTER inherits team_id so keys are bounded by team limits

Auto-registered virtual keys were created with no team, model, route, rate, or
budget constraints — broader access than the standard team-based JWT auth path
the same client would have taken. Under AUTO_REGISTER, resolve the team_id
from the JWT (via the operator-configured team_id_jwt_field / team_id_default)
and stamp it on the new key. Downstream auth then applies the team's
budget/models/tpm/rpm/allowed_routes via the existing virtual-key flow.

Policy when team_id_jwt_field is configured:
  - JWT carries team claim → stamp resolved team_id
  - JWT lacks claim + team_id_default set → stamp default
  - JWT lacks claim + no default → 403 (refuse to create an unbounded key)

When neither team_id_jwt_field nor team_id_default is configured, the
operator has explicitly opted out of team-based limits — the auto-created
key has no team_id (matches what team-auth would do in the same config).

Adds 4 tests covering each branch.

* fix(jwt): make AUTO_REGISTER functional in prod; raise on missing winner

Two correctness fixes flagged by Greptile on the AUTO_REGISTER path:

1. generate_key_helper_fn was called without table_name="key". Without that,
   the helper falls into the user-upsert branch (table_name in (None, "user"))
   and tries to insert into LiteLLM_UserTable with user_id=None, which hits
   the NOT NULL @id constraint. AUTO_REGISTER would never have succeeded in
   production. Now passes table_name="key" explicitly, matching the
   /key/generate caller.

2. When the race loser refetches the winner's mapping and gets None (winner
   row concurrently deleted), the previous code returned None — and the
   caller in _resolve_jwt_to_virtual_key then fell through to less-
   restrictive team-based JWT auth, silently bypassing the configured
   AUTO_REGISTER policy. Now raises HTTP 503 so the caller retries against
   a stable state rather than getting unintended fallback access.

Adds one test for the 503 winner-vanishes path.

* fix(jwt): defer AUTO_REGISTER until JWT policy is enforced by auth_builder

Closes the JWT policy bypass on the AUTO_REGISTER path flagged by veria-ai.

Before: when unregistered_jwt_client_behavior=auto_register and the JWT's
claim was unmapped, _resolve_jwt_to_virtual_key validated the JWT signature
and then immediately created a virtual key + mapping. JWTAuthManager.auth_builder
never ran for the first request (the new key short-circuited the team-auth
path), and every subsequent request hit the cached mapping — so custom_validate,
RBAC, scope_mappings, and user_allowed_email_domain were never enforced for
auto-registered clients.

After: _resolve_jwt_to_virtual_key returns a _PendingAutoRegister signal
instead of creating the key. The caller in _user_api_key_auth_builder runs
JWTAuthManager.auth_builder, then — only on a validated, policy-passing
result — calls _auto_register_jwt_mapping with the team_id / user_id from
that result. The created key inherits team + user limits from the validated
identity, and future cache hits load that already-policy-checked key.

Also drops the interim _resolve_inherited_team_id helper that pulled team_id
from raw JWT claims — same bypass risk; team_id now comes exclusively from
auth_builder.

Tests:
  - Rewrote two existing tests to assert _resolve_jwt_to_virtual_key returns
    _PendingAutoRegister (no key created yet) for both the fresh-DB-miss
    and stale-sentinel branches
  - Added a contract test that _auto_register_jwt_mapping stamps the
    validated team_id/user_id onto generate_key_helper_fn
  - Removed four stale team-binding tests that exercised the prior
    raw-claim helper

* Update user_api_key_auth.py

* fix(jwt): cache proxy-admin AUTO_REGISTER path to avoid repeated DB lookups

Cache-miss regression introduced by the deferred-auto-register refactor:
when a JWT under AUTO_REGISTER resolved to a proxy admin, the is_proxy_admin
early-return in _user_api_key_auth_builder ran *before* the pending
auto-register cache-write block. Result: no cache entry, so every
subsequent proxy-admin request re-queried get_jwt_key_mapping_object
indefinitely.

Fix: write a __JWT_PROXY_ADMIN__ sentinel to user_api_key_cache before the
early return when a pending auto-register existed. _resolve_jwt_to_virtual_key
treats that sentinel as "skip mapping, fall through to auth_builder", so
future requests from the same JWT identity hit the cache instead of the DB.
auth_builder still runs full JWT policy on every request — only the
mapping DB lookup is short-circuited.

Adds one test asserting the sentinel cache-hit returns None without
hitting prisma_client.db.litellm_jwtkeymapping.find_first.

Litellm oss staging 040626 (#29671)
* fix(azure): apply api_version fallback chain to image edit URL

`AzureImageEditConfig.get_complete_url` only read `api_version` from
`litellm_params`. When callers configured it via `litellm.api_version`
or `AZURE_API_VERSION`, the constructed URL had no `?api-version=` and
Azure responded `404 Resource not found`.

Apply the same fallback chain the Azure chat path already uses in
`common_utils.py`:

    litellm_params > litellm.api_version > AZURE_API_VERSION env >
    litellm.AZURE_DEFAULT_API_VERSION

Adds 5 unit tests pinning each layer of the chain plus a regression
guard for `api_base` that already carries `?api-version=`.

* feat(mcp): core sampling and elicitation flow with security hardening

- Add sampling_handler.py: full MCP sampling/createMessage flow with
  model selection (hint-based + priority-based), auth enforcement,
  budget checks, route restriction gates, and tag policy pre-auth
- Add elicitation_handler.py: MCP elicitation/create relay with
  downstream client capability detection
- Wire sampling/elicitation callbacks in mcp_server_manager.py
  gated behind allow_sampling/allow_elicitation config flags
- Add allow_sampling/allow_elicitation fields to MCPServer type
- Fix session lock deadlock: skip lock for JSON-RPC response POSTs
  (elicitation/sampling replies) with truncated-body heuristic
- Extend client.py with sampling_callback and elicitation_callback
- Security: RouteChecks gate, tag-budget bypass fix, x-forwarded-for
  spoofing fix, Latin-1 header encoding guard
- Add 4 new test modules (model access, priority selection, request
  builder, tool conversion) + update existing MCP tests

* fix(security): run pre-call guardrails before MCP sampling acompletion

Without this, an upstream MCP server with allow_sampling enabled could
send prompts that bypass every guardrail (content filtering, PII
redaction, prompt-injection detection) configured on /chat/completions.

- Call proxy_logging_obj.pre_call_hook(call_type='acompletion') before
  llm_router.acompletion so guardrails fire for sampling sub-calls
- Add HTTPException to the re-raise list so guardrail rejections
  propagate correctly instead of being swallowed as generic errors

* feat(bedrock_mantle): add gpt-5.5/gpt-5.4 Responses price-map entries

* refactor(bedrock_mantle): exclude gpt-oss instead of allow-listing gpt-5 for Responses routing

Frontier OpenAI models on Bedrock Mantle are Responses-only on /openai/v1/responses;
gpt-oss is the legacy family that also speaks chat-completions. Gate by excluding
gpt-oss (which keeps its chat-completions emulation) and defaulting everything else
to the native Responses config, so future frontier models (gpt-6, etc.) route
correctly without a code change. Verified against the live us-east-2 Mantle endpoint:
gpt-oss 400s on /openai/v1/responses while gpt-5.5 400s on both standard paths.

* test(bedrock_mantle): cover supports_native_websocket opt-out

Closes the one uncovered line flagged by codecov on the Responses config.
The assertion documents that Mantle Responses has no realtime/websocket
transport, so realtime routing must not attempt a socket it cannot serve.

* fix(bedrock_mantle): route file_search through emulation instead of forwarding to Mantle

BedrockMantleResponsesAPIConfig inherited supports_native_file_search()
-> True from OpenAIResponsesAPIConfig but never overrode it. Mantle has no
OpenAI vector stores, so a forwarded file_search tool is rejected with a
400 (verified upstream: Tool type 'file_search' is not supported). Opting
out, like the existing supports_native_websocket override, routes the tool
through LiteLLM's file_search emulation instead.

* fix(bedrock_mantle): only route openai.gpt frontier models to Responses

The previous gate excluded gpt-oss and routed every other model to the
native Responses config. But on Mantle only the OpenAI gpt frontier models
(gpt-5.x) are served on /openai/v1/responses; gpt-oss and the non-OpenAI
families (nvidia, mistral, google, zai, ...) are chat-completions only and
400 on that path. Allow-list the openai.gpt- family (excluding gpt-oss)
instead, so chat-only models fall through to the chat-completions emulation.
Verified against the live us-east-2 endpoint: nvidia.nemotron-nano-9b-v2
returns 400 on /openai/v1/responses and 200 on /v1/chat/completions.

* fix(proxy): strip stack trace from HTTP 503 responses (CWE-209) (#28330)

The /cache/ping endpoint included a full Python traceback in its 503 error
response body (inside the ProxyException message), leaking internal file
paths, line numbers, and call stacks to any caller. Two MCP route handlers
in proxy_server.py similarly interpolated str(e) into "Internal server
error" detail strings.

Fix: log the traceback server-side via verbose_proxy_logger.exception()
and omit it from the ProxyException payload / HTTPException detail returned
to clients. Tests updated to assert no "traceback" keyword or frame paths
appear in the 503 body, with a new dedicated regression test.

* fix(proxy/cwe-209): apply Greptile P2 fixes and add MCP exception-path tests

Greptile 4/5 review identified two remaining gaps and Codecov reported
0% coverage on the two MCP handler exception branches:

1. caching_routes.py — str(e) in "Service Unhealthy ({str(e)})" could
   still leak Redis hostnames/IPs; replaced with static "Service Unhealthy".
   HTTPException is now re-raised before the generic handler so the
   "cache not initialized" 503 still reaches callers with its detail.
   Removed the redundant str(e) arg from verbose_proxy_logger.exception()
   (exception() already appends the traceback automatically).

2. tests — two new unit tests cover the exception paths in
   dynamic_mcp_route and toolset_mcp_route that were previously at 0%:
   - test_dynamic_mcp_route_unexpected_exception_returns_500_without_traceback
   - test_toolset_mcp_route_unexpected_exception_returns_500_without_traceback

All 25 tests pass (9 caching + 16 MCP).

* test(caching_routes): restore precise assertion and add CWE-209 no-cache path test

The assertion in test_cache_ping_no_cache_initialized was weakened to
`"Cache not initialized" in str(data)`, which matched against the raw string
representation of the entire response dict. This would pass silently even if
the error message moved to an unexpected field or the structure changed.

Restore a targeted assertion on the parsed field:
  assert data["detail"] == "Cache not initialized. litellm.cache is None"
matching FastAPI's HTTPException serialisation format exactly.

Add test_cache_ping_no_cache_does_not_expose_internals to show the code path
is still working correctly after the CWE-209 fix: verifies that the HTTPException
is re-raised as-is (no traceback, no source paths), and asserts the complete
response structure is exactly {"detail": "Cache not initialized. litellm.cache is None"}.

* fix(caching_routes): restore ProxyException envelope for null-cache 503

The except HTTPException: raise guard (added in the CWE-209 fix) caused
the null-cache HTTPException to escape as FastAPI's {"detail": "..."} shape
instead of the {"error": {...}} ProxyException envelope that callers expect.

Move the null-cache guard before the try block and raise ProxyException
directly so the response structure is consistent with all other /cache/ping
503s, and the except HTTPException: raise guard is only reachable by
unexpected downstream HTTPExceptions.

Update the two no-cache tests to assert the correct ProxyException envelope.

* Update utils.py (#26609)

* feat(pricing): add Snowflake Cortex REST API model pricing (#26612)

* feat(pricing): add Snowflake Cortex REST API model pricing

## Summary

Adds pricing and context window information for 20+ Snowflake Cortex REST API models to `model_prices_and_context_window.json`.

## What's included

- **7 Claude models** (sonnet-4-5, sonnet-4-6, 4-sonnet, 4-opus, haiku-4-5, 3-7-sonnet, 3-5-sonnet) — with prompt caching rates
- **4 OpenAI models** (gpt-4.1, gpt-5, gpt-5-mini, gpt-5-nano) — with prompt caching rates  
- **5 Llama models** (3.1-8b, 3.1-70b, 3.1-405b, 3.3-70b, 4-maverick)
- **1 DeepSeek model** (deepseek-r1)
- **1 Mistral model** (mistral-large2)
- **1 Snowflake model** (snowflake-llama-3.3-70b)
- **2 Embedding models** (arctic-embed-l-v2.0, arctic-embed-m-v2.0)

Each entry includes `input_cost_per_token`, `output_cost_per_token`, `cache_read_input_token_cost` (where applicable), `max_input_tokens`, `max_output_tokens`, and capability flags (`supports_function_calling`, `supports_vision`, `supports_prompt_caching`, `supports_reasoning`).

## Pricing source

All prices are in USD per token, sourced from the official [Snowflake Service Consumption Table](https://www.snowflake.com/legal-files/CreditConsumptionTable.pdf) — Tables 6(b) (REST API with Prompt Caching) and 6(c) (REST API).

## Context

The existing `snowflake/` provider has zero model entries in the pricing JSON, which means LiteLLM cannot track costs for Snowflake Cortex calls. This PR fills that gap.

returns the original dict reference when extra_body is non-empty (truthy).
Subsequent writes like extra_body[k] = passed_params[k] then mutate the
shared model config object held by the router, poisoning /model/info and
all subsequent requests for that deployment.

The or {} short-circuit creates a new dict only when extra_body is falsy
(None or {}), which is why the bug does not reproduce with extra_body: {}.

The Gemini path was leaving image in params_copy, so it ended up
nested under parameters and the API silently ignored it.

The Vertex path already builds the instance dict explicitly, so this
just aligns the Gemini path with it.

Fixes #29498

* address greptile: unconditional pop + BytesIO test

- Pop `image` from params_copy unconditionally so it never reaches
  GeminiVideoGenerationParameters even when None, removing implicit
  reliance on Pydantic's extra-field-ignore.
- Add test_transform_video_create_request_image_filelike_goes_to_instance
  covering the BytesIO path (_convert_image_to_gemini_format) — round-trips
  the base64 to confirm encoding.
- Add test_transform_video_create_request_image_none_is_dropped covering
  the new None branch.

* fix(huggingface): handle special token text in embedding usage (#29660)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params (#29655)

* fix(guardrails): recompile ToolPermissionGuardrail rules on update_in_memory_litellm_params

ToolPermissionGuardrail builds self.rules and the compiled target/pattern
maps only in __init__. The base update_in_memory_litellm_params re-sets raw
attributes via setattr but never rebuilds those maps, so a guardrail updated
in place (PUT /guardrails, or the immediate in-memory sync) keeps enforcing
the construction-time rules until it is reinitialized (PATCH path, periodic
DB poll, or restart).

Extract the compile step into _load_rules and override
update_in_memory_litellm_params to rebuild from it (dict- and model-safe),
re-normalizing default_action / on_disallowed_action. Mirrors the existing
PresidioGuardrail override of the same method. Adds regression tests.

Fixes #29592.

* fix(guardrails): handle dict params in ToolPermissionGuardrail in-memory update

Delegate to super() only for LitellmParams input (the base setattr loop is
model-only); apply the raw-dict case inline. Fixes the mypy arg-type error
and makes the recompile work when the proxy passes the raw DB dict.

* fix(guardrails): preserve tool-permission rules on a partial in-memory update

A partial update (e.g. a LitellmParams whose rules field is None) ran through
the generic setattr, which set self.rules to None, and the recompile was
skipped, leaving the guardrail with no rules. Snapshot the previous rules and
restore them when the update carries no rules; an explicit empty list still
clears them. Adds a regression test for the rules-absent case.

Addresses the Greptile review note on #29655.

* fix(bedrock): stop base_model label from stripping tools/tool_choice (#29621)

* fix(bedrock): stop base_model label from stripping tools/tool_choice

A Router/proxy Bedrock deployment whose model_info.base_model is a friendly
label (e.g. claude-haiku-4-5) silently lost tools/tool_choice: the outgoing
Converse request was built without toolConfig, so the model behaved as if no
tools were provided. Worked in v1.84.0, regressed in v1.85.0, and with
drop_params=true it failed silently.

Two changes compound into the bug. completion() passed model_info.base_model
as the model argument to get_optional_params, so the real Bedrock model id
never reached supported-param resolution; and get_supported_openai_params
resolved the provider config's params from base_model or model, letting the
label fully replace the real model. For Bedrock the label resolves to no tool
support, so tools/tool_choice were dropped before transformation.

completion() now keeps model as the real deployment model and threads the
resolved base_model (kwarg or model_info) through separately, and
get_supported_openai_params treats base_model as additive: it returns the
union of the params supported by model and by base_model. A hint can only add
capabilities, never strip ones the real model already exposes, which also
preserves the original base_model behavior from #27717 and Azure's base_model
driven model-type detection.

Fixes #29618

* test(main): make base_model param test robust to new parametrize cases

Restore an explicit per-case expected_model_param literal instead of
hardcoding the gemini id, so a future case with a different model can't
produce a misleading assertion failure.

* fix(fireworks_ai): pass response_format json_schema through unchanged (#29606)

FireworksAIConfig.map_openai_params was rewriting the OpenAI strict
`{type: json_schema, json_schema: {name, strict, schema}}` shape into
`{type: json_object, schema: ...}` before sending to Fireworks, dropping
`strict` and `name` and changing the `type`. Per Fireworks' docs json_object
means "force any valid JSON output (no specific schema)", so the schema
constraint was effectively dropped and grammar-guided decoding never ran;
model output silently violated the schema.

The rewrite landed in #7085 (Dec 2024) when Fireworks did not yet accept
native json_schema. Fireworks accepts the OpenAI strict shape natively now,
so the rewrite has become a regression.

Removes the rewrite. Passes response_format through unchanged. Updates the
existing test_map_response_format to assert pass-through. Adds focused
regression tests in tests/test_litellm/ covering preservation of type,
strict, name, and schema body, plus that json_object alone still works.

* fix(test): use .value when comparing LlmProviders enum against string in test_default_api_base

* fix(test): iterate LlmProviders enum in test_default_api_base to avoid str pollution from custom provider registration

litellm.provider_list is a mutable global initialized to list(LlmProviders) but custom_llm_setup() appends plain provider strings to it. When a test_custom_llm.py test runs first in the same xdist worker, provider_list contains a str and calling .value on it raises AttributeError. Iterate the immutable LlmProviders enum instead, which is deterministic and what the check intends.

* fix(mcp): depth-aware JSON-RPC response detection and neutral speed-priority fallback

Replace the flat substring check in the truncated-body routing path with a
top-level-key scan so a JSON-RPC response whose result payload nests a
"method" field is still detected as a response and skips the session lock,
removing a deadlock against the in-flight tool call awaiting it.

Drop the inverse max_output_tokens speed proxy when no model exposes
output_tokens_per_second; context-window size does not track latency, so a
neutral score avoids biasing speedPriority toward the smallest-context model.

* fix(guardrails): make ToolPermission rule reload atomic on invalid regex

_load_rules appended each rule to self.rules before compiling its regex, so an
invalid pattern raised mid-loop after the bad rule was already live but without
a _compiled_rule_targets entry. _matches_regex reads a missing compiled target
as a None pattern and returns True, turning the bad rule into a match-all that
silently applies its decision to every tool. Via update_in_memory_litellm_params
(PUT /guardrails) this corrupted the live guardrail.

Build the parsed rules and compiled maps into locals and swap them in only after
every regex compiles, and restore the previous ruleset if a live update is
rejected, so an invalid regex now fails the update without leaving the guardrail
enforcing a broken policy.

* test(mcp): cover sampling conversion, model resolution, and elicitation relay paths

The MCP sampling and elicitation handlers shipped with partial test
coverage, leaving the response-to-MCP conversion, the model resolution
fallback chain, completion-kwargs assembly, guardrail routing, and the
entire elicitation relay untested. That pulled the PR's diff (patch)
coverage below the codecov threshold even though overall project
coverage rose.

Add focused unit tests for _convert_openai_response_to_mcp_result,
_convert_mcp_tools_to_openai, _convert_mcp_tool_choice_to_openai, image
and audio content conversion, the hint-matching and fallback branches of
_resolve_model_from_preferences, _build_completion_kwargs, the router and
guardrail-rejection paths of _run_guardrails_and_call_llm, the
handle_sampling_create_message success and error-propagation flows, the
marker-hoisting fallback for tool content on unexpected roles, and the
elicitation form/url/generic relay together with its decline paths

fix(proxy): disable proxy buffering on streaming SSE responses (#29557)
Streaming responses from the proxy (/chat/completions, /v1/messages,
/v1/responses, assistants) all return through create_response() but never
sent the headers that tell an intermediary reverse proxy not to buffer the
SSE stream. nginx with the default proxy_buffering, k8s ingress-nginx, and
Envoy/Istio sidecars therefore hold the whole stream and release it in one
batch, which looks like a broken/buffered stream to the client even though
litellm is yielding chunks incrementally.

Add Cache-Control: no-cache and X-Accel-Buffering: no to every
StreamingResponse create_response() returns, matching what the proxy already
does for its own usage/policy SSE endpoints. Fixes #28384.

#29612 exempts UI/CLI session tokens from the key budget ceiling when they
create a team key, keyed on data.team_id. That value is read after the
default_key_generate_params loop can populate team_id, so on deployments that
set default_key_generate_params.team_id a request the caller did not scope to a
team is treated as a team key and skips the ceiling. Capture _requested_team_id
before defaults run and key the exemption off it, mirroring how
_requested_max_budget is already captured. Requests the caller did not scope to a
team keep the ceiling.

fix(key_generate): exempt UI/CLI session tokens from the budget ceiling for team keys (#29612)
Non-admin users creating a team key through the UI were rejected with
"max_budget cannot exceed the caller's own max_budget (0.25)". The request is
authenticated by a UI/CLI session token whose max_budget is the per-session chat
spend cap (max_ui_session_budget, default $0.25), and the delegated-authority
budget ceiling (GHSA-q775-qw9r-2r4g) treated that cap as a delegation limit.

Skip the ceiling only when a session token creates a team key (data.team_id set);
that key's spend is bounded by the team budget at request time. Personal keys and
every other non-admin caller keep the ceiling, so a session token cannot mint an
arbitrary-budget personal key.

fix: passthrough endpoints duplicate logs (#29598)
* fix duplicate cost callbacks for anthropic streaming pass-through

Two bugs caused _PROXY_track_cost_callback to see stream=True +
complete_streaming_response=None on every streaming pass-through request,
making the dedup guard in dispatch_success_handlers permanently inactive:

1. pass_through_endpoints.py created the Logging object with stream=False
   for all requests. _is_assembled_stream_success short-circuits on
   self.stream is not True, so has_dispatched_final_stream_success was
   never set and any second dispatch went through unchecked.
   Fix: set logging_obj.stream = True after stream detection.

2. _create_anthropic_response_logging_payload set complete_streaming_response
   inside the try block after litellm.completion_cost(), so a pricing error
   caused an early return without setting it on model_call_details.
   Fix: set complete_streaming_response before the try block.

Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

* fix stream

* add stream to logging obj

* test(pass_through): give mock logging object a real model_call_details dict

The anthropic passthrough logging payload now records the assembled
response on model_call_details before cost calculation, which requires
model_call_details to support item assignment. In production it is always
a dict; the existing unit test stubbed the logging object with a bare Mock
whose attribute is not subscriptable, so the new assignment raised
TypeError. Use a real dict to match the production logging object.

* test(pass_through): cover streaming logging-obj stream flag

The streaming branch of pass_through_request that marks the logging object
as streaming (logging_obj.stream and model_call_details["stream"]) had no
unit coverage, so the patch coverage gate flagged it. Add a regression test
that drives a streaming pass-through request through pass_through_request and
asserts the logging object is flagged as a stream before dispatch.

* test(pass_through): cover SSE-response stream flag fallback branch

The auto-detected streaming branch of pass_through_request (when a request
that was not flagged as streaming returns a text/event-stream response) sets
logging_obj.stream and model_call_details["stream"] but had no unit coverage,
so the codecov patch gate failed at 60%. Drive a non-streaming pass-through
request whose upstream response is SSE through pass_through_request and assert
the logging object is flagged as a stream before dispatch.

* fix(pass_through): gate complete_streaming_response on stream flag

perform_redaction only scrubs complete_streaming_response when
model_call_details["stream"] is True. Setting it unconditionally for
non-streaming Anthropic pass-through responses left the assembled
response unredacted in model_call_details, which is handed to logging
callbacks as kwargs when message logging is disabled. Only record it for
actual streaming responses so redaction always applies.

Litellm websocket improvements (#29563)
* Add support for websocket via codex

* Add model alias and creds support

* fix: skip cost tracking for WS session wrapper call types

The @client decorator on _aresponses_websocket fires async_success_handler
with result=None after the session ends. This triggered cost tracking errors
because standard_logging_object is never built for None results.

Per-turn costs are correctly tracked by individual litellm.aresponses calls
inside the session. The outer session-level logging obj should not attempt
cost tracking.

Fix: skip _aresponses_websocket and _arealtime call types in deployment_callback_on_success,
RouterBudgetLimiting.async_log_success_event, and _PROXY_track_cost_callback.

* fix: address Greptile review comments

Fix JSON injection: use json.dumps instead of f-string interpolation for model name in WS body.

Add 30s timeout for first WS frame to prevent unbounded connection resource tie-up.

Restore per-event model override in streaming_iterator; fall back to connection-level model when event omits it.

Strengthen regression test: inject alias into kwargs via _update_kwargs_with_deployment mock so the test would fail on un-fixed code.

* fix: handle nested response.create format in first-frame model extraction

When ?model= is omitted, the first WS frame can carry the model in either flat
format (first_event["model"]) or nested format (first_event["response"]["model"]).
The flat-only check would silently reject clients using the nested wire format.

Mirrors the same two-format logic in _build_base_call_kwargs.

* fix: don't force connection-level custom_llm_provider on per-event model overrides

If a client sends a different model per response.create turn, litellm needs to
re-resolve the provider from that model string. Forcing the connection-level
custom_llm_provider would silently route the request to the wrong backend.

Only inject custom_llm_provider when the per-event model matches the
connection-level model.

* refactor: extract WS model extraction into testable function

Pull the flat/nested model extraction into _extract_model_from_first_ws_event
so tests import and exercise the real function rather than a copy.

* fix: compare providers not full model strings in _inject_credentials

The model == self.model guard was too strict: same-provider model variants
(e.g., vertex_ai/gemini-2.0 -> vertex_ai/gemini-1.5 on one connection) would
lose custom_llm_provider, breaking routing when a custom api_base is in use.

Compare the provider extracted by get_llm_provider instead, so same-provider
variants still inherit the connection-level provider while cross-provider
overrides let litellm re-resolve.

* style: black formatting

* refactor: extract first-frame model resolution to fix PLR0915 (too many statements)

* Fix responses WebSocket first-frame validation

* fix: classify WS first-frame read errors and clarify cost-skip log

Distinguish client disconnects from server errors when reading the
responses WebSocket first frame, make the cost-tracking skip log message
accurate for session wrappers (which do carry a model), and resolve the
connection-level provider once per session instead of on every
response.create event.

* test: cover WS first-frame read errors and same-provider credential injection

Adds regression tests for the still-uncovered responses WebSocket paths:
the timeout, invalid-JSON and missing-model branches of
_read_ws_model_from_first_frame, plus the provider comparison in
ManagedResponsesWebSocketHandler._same_provider and _inject_credentials
(same-provider model variants keep the connection provider; cross-provider
models re-resolve).

* fix(responses-ws): fall back to explicit custom_llm_provider when connection model is unresolvable

When a WebSocket session is opened with a custom deployment alias that litellm
cannot resolve to a provider, _connection_provider was None, so _same_provider
returned False for every resolvable per-event model and the connection-level
custom_llm_provider was dropped. Use the explicitly-set custom_llm_provider as
the connection provider in that case so same-provider per-event models still
inherit it while genuinely cross-provider models continue to re-resolve.

fix(anthropic/adapter): emit thinking block for reasoning_content-only streaming chunks (#29600)
* fix(anthropic/adapter): open thinking block for reasoning_content-only streaming chunks

The /v1/messages streaming content-block classifier (_translate_streaming_openai_chunk_to_anthropic_content_block) only recognized thinking_blocks. OpenAI-compatible reasoning backends (vLLM/SGLang reasoning parsers: DeepSeek-R1, Qwen3, gpt-oss, ...) populate reasoning_content with thinking_blocks=None, so the classifier fell through to a text block. The delta translator already emits thinking_delta for reasoning_content, so those deltas landed inside a text block and Anthropic streaming clients (Claude Code, SDK .stream()) silently dropped the chain-of-thought.

Mirror the reasoning_content fallback already present in the non-stream translator and the streaming delta translator so the classifier opens a thinking block. Adds a focused regression test.

* fix(anthropic/adapter): reach reasoning_content branch when thinking_blocks attr is absent

Delta deletes the thinking_blocks attribute when unset, so the prior nested check was unreachable for reasoning-only chunks (vLLM/SGLang). Make it a sibling elif so the content block is classified as thinking.

* test(proxy): stop component-allowlist test leaking DATABASE_URL into xdist peers

The component-allowlist test pins throwaway DATABASE_URL/LITELLM_MASTER_KEY
values at import time via os.environ so importing proxy_server doesn't need a
live database. Those values persisted for the whole pytest-xdist worker, so a
sibling test sharing the worker (test_key_rotation_e2e's DB-backed E2E case)
saw the leaked sqlite DATABASE_URL, treated it as an available database instead
of skipping, and the Prisma engine rejected the non-postgres URL (P1012 ->
httpx.ConnectError). Restore the prior environment after the import so the
throwaway values never escape the module.

Fix : a2a bugs 030626 (#29566)
* Fix error code and context id injection bug

* Add support for all A2A methods

* Add logging

* address greptile review: relay upstream JSON-RPC errors, move _PASCAL_TO_WIRE to module level, add error path tests

* fix(a2a): run pre_call_hook for tasks/resubscribe SSE path to enforce guardrails

tasks/resubscribe was returning the raw SSE stream without calling proxy_logging_obj.pre_call_hook, silently bypassing any guardrails configured on the agent. This patch calls pre_call_hook before streaming begins and wires post_call_failure_hook into the SSE generator so errors are logged. Adds a regression test verifying the hook is called.

* fix(a2a): use get_async_httpx_client instead of creating httpx clients per request

Creating httpx.AsyncClient instances per-request adds ~500ms latency. Switch _forward_jsonrpc and _forward_jsonrpc_sse to use the shared client from get_async_httpx_client(httpxSpecialProvider.A2A).

* fix(a2a): forward caller identity headers on task ops; validate push notification URL

Two security fixes for task management methods:

1. All task operations (tasks/get, tasks/list, tasks/cancel, tasks/resubscribe, push notification config methods) now forward X-LiteLLM-User-Id and X-LiteLLM-Team-Id headers to the upstream agent, so the agent can scope task access to the authenticated caller.

2. tasks/pushNotificationConfig/set validates the callback URL before forwarding: requires HTTPS and rejects private/loopback/reserved IP ranges and localhost hostnames to prevent SSRF.

* Fix A2A task hook and push URL handling

* fix(a2a): fix mypy type errors for request_id and header_name dict key types

* Fix A2A request id and params forwarding

* Forward trace IDs for A2A task calls

* fix(a2a): strip client-forwarded X-LiteLLM-* headers before applying authenticated identity

A client could send x-a2a-<agent>-x-litellm-user-id in their request and have it forwarded to the upstream agent as an authenticated identity header. Fix: sanitize any X-LiteLLM-* headers from agent_extra_headers before merging, then apply the authenticated identity headers last so they always override client-supplied values.

* Fix A2A SSE fallback JSON-RPC error code

* Fix A2A SSE error id backfill

* fix(a2a): validate both push notification url fields to close SSRF bypass

* fix(a2a): widen request_id annotation to match JSON-RPC id call sites

* fix(a2a): run post-call streaming hook for tasks/resubscribe so agent guardrails apply

tasks/resubscribe returned the raw upstream SSE stream without routing events
through the post-call streaming hook, so output guardrails configured on the
agent were silently skipped for streaming task subscriptions while every other
task method and message/stream applied them. Parse upstream JSON-RPC SSE events
and feed them through async_streaming_data_generator, matching message/stream,
so guardrails inspect the streamed task content. Adds a regression test that
fails when the streamed events bypass the guardrail hook.

Litellm oss staging 030626 (#29578)
* Fix incorrect agent API request example payload structure (#29556)

* fix(otel): add litellm_metadata fallback in _get_span_context and _end_proxy_span_from_kwargs (#29427)

* fix(otel): add litellm_metadata fallback in _get_span_context and _end_proxy_span_from_kwargs

On /v1/messages and other LITELLM_METADATA_ROUTES, the parent OTel span
is stored in litellm_params['litellm_metadata'] instead of
litellm_params['metadata']. When the request body contains a native
'metadata' field (e.g. Anthropic's {"user_id": "..."}),
litellm_params['metadata'] gets overwritten and the parent span is lost,
producing orphan root spans with a different trace_id.

Add fallback checks to litellm_metadata in:
- _get_span_context(): so child spans find the correct parent
- _end_proxy_span_from_kwargs(): so the proxy span gets closed

Fixes: https://github.com/BerriAI/litellm/issues/27934

* test(otel): tighten assertions per Greptile review

- test_span_context_metadata_takes_priority: assert litellm_metadata
  span is never accessed, proving metadata takes priority
- test_span_context_no_parent_when_neither_has_span: assert both ctx
  and detected_span are None

* fix: remove premature end-user budget check from get_end_user_object (#29420)

* fix(proxy): remove premature end-user budget check from get_end_user_object

Problem:
- `_check_end_user_budget()` was called inside `get_end_user_object()`
- This caused budget checks to run BEFORE `skip_budget_checks` could be evaluated
- Zero-cost models (e.g., local vLLM) were incorrectly blocked when
  end-users exceeded their budget, even though they should bypass budget checks

Solution:
- Remove `_check_end_user_budget()` calls from `get_end_user_object()`
- Budget enforcement now happens exclusively in `common_checks()` where
  `skip_budget_checks` context is available
- `get_end_user_object()` keeps `route` as optional in function parameter for backwards compatibility and future implementation.

* refactor(tests): update budget enforcement tests to reflect changes in get_end_user_object

- test_get_end_user_object() verifies data fetching
- test_check_end_user_budget() verifies enforcement
- test_budget_enforcement_blocks_over_budget_users() integrates _check_end_user_budget()
- test_resolve_end_user_reraises_budget_exceeded() is now test_resolve_end_user since no budget exceeded is thrown in get_end_user_object()

* fix(vertex/gemini): keep tool_call reference when a text-only assistant message follows (#29561)

`_gemini_convert_messages_with_history` tracks `last_message_with_tool_calls`
so a following tool result can be matched back to its tool call. The assignment
was inside a branch guarded by
`assistant_msg.get("tool_calls", []) is not None`, which is also True for a
text-only assistant message (an empty list is not None). As a result, an
assistant message with no tool calls that appears between a tool call and its
tool result overwrote the reference, and conversion failed with:

    Exception: Missing corresponding tool call for tool response message.

This shape is common: a model emits a short narration/assistant message after a
tool call before the tool result is appended.

Only update `last_message_with_tool_calls` when the assistant message actually
carries tool_calls (or a function_call). Adds a regression test.

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505) (#28575)

* Forward custom_llm_provider through the Responses API bridge (Fixes #28505)

When a Chat Completions request to a GPT-5.4+ model contains both
`tools` and `reasoning_effort`, `completion()` auto-routes through
`responses_api_bridge`. The bridge handler called
`litellm.responses()` / `litellm.aresponses()` without forwarding the
already-resolved `custom_llm_provider`, so the downstream call
re-invoked `get_llm_provider()` with `custom_llm_provider=None` and
stripped a second provider prefix from a `provider/provider/model`
deployment string.

For a deployment configured as `openai/openai/openai/gpt-5.5`,
the bridge flow sent `openai/gpt-5.5` to the upstream API instead of
the correct `openai/openai/gpt-5.5`. Upstream APIs that enforce
model-name allow-lists rejected this as `key_model_access_denied`.

Fix: pass the locally-resolved `custom_llm_provider` into both the
sync `responses()` and async `aresponses()` calls so the downstream
`_resolve_model_provider_for_responses` sees an explicit provider
and skips the second prefix-strip.

New regression test
`tests/test_litellm/completion_extras/test_responses_bridge_provider_propagation.py`
pins both call sites: each must forward `custom_llm_provider`.

* fix(28505): set custom_llm_provider on request_data instead of as duplicate kwarg

Greptile flagged that the previous patch passed custom_llm_provider as an
explicit kwarg to responses()/aresponses() while request_data already
carried it via the spread of sanitized_litellm_params, which would raise
TypeError: got multiple values for keyword argument on every real bridge
call.

Switches to assigning request_data['custom_llm_provider'] before the call
so the resolved provider wins over whatever sanitized_litellm_params spread
in, without duplicating the kwarg.

Updates the regression test to seed request_data with a sentinel
custom_llm_provider so it actually exercises the overwrite path (the
previous test mocked transform_request with a minimal dict and never hit
the conflict).

* Add 1-hour cache write pricing for EU/AU/JP Bedrock Anthropic models

The 1-hour prompt-cache write tier
(`cache_creation_input_token_cost_above_1hr`) was added to the
us./global. variants of the Claude 4.5/4.6/4.7 family on Bedrock, but
the eu./au./jp. cross-region inference profiles were left without it.
AWS Bedrock pricing applies the same +10% regional premium across all
geo profiles, so eu./au./jp. should carry the same 1-hour rates as
us. (1.6x the 5-minute regional rate).

Without these fields, cost tracking on EU/AU/JP Bedrock 1-hour-TTL
prompt caching falls back to the 5-minute write rate and undercounts
spend by ~60% for European, Australian, and Japanese tenants.

Adds the 1-hour tier (and Sonnet 4.5's long-context >200K tier where
AWS publishes one) to 14 regional Bedrock entries in both
`model_prices_and_context_window.json` and the bundled
`model_prices_and_context_window_backup.json`:

  - eu./au.   Opus 4.6     ($11.00 / MTok)
  - eu./au.   Opus 4.7     ($11.00 / MTok)
  - eu./au./jp. Sonnet 4.6 ($6.60 / MTok)
  - eu./au./jp. Sonnet 4.5 ($6.60 / MTok regular, $13.20 / MTok LC)
  - eu./au./jp. Haiku 4.5  ($2.20 / MTok)

Also extends `tests/test_litellm/test_bedrock_anthropic_1hr_cache_pricing.py`
with a `REGIONAL_EXPECTED` parametrized block covering all 13 new
entries plus the existing 1.6x ratio invariant.

Note: `eu.anthropic.claude-opus-4-5-20251101-v1:0` carries the
wrong 5m rate today (base 6.25e-06 instead of regional 6.875e-06),
which would break the 1.6x ratio check. It is intentionally left out
of this PR so the scope stays "1-hour cache tier addition" — a
separate follow-up should correct the EU 5m rates for Opus 4.5.

* Add 1-hour cache write pricing tier for Vertex AI Anthropic models

GCP Vertex AI publishes a separate 1-hour cache write column for the
Claude family (1.6x the 5-minute write rate, matching the documented
Bedrock ratio). LiteLLM's Vertex AI Anthropic entries only carry the
5-minute tier, so any request that uses `cache_control: {"ttl": "1h"}`
on Vertex AI Claude is undercounted in cost tracking by ~60%.

The runtime side already supports the 1-hour tier — `VertexAIAnthropicConfig`
extends `AnthropicConfig`, populating `ephemeral_1h_input_tokens`, and
`_calculate_cache_creation_cost` reads `cache_creation_input_token_cost_above_1hr`.
Only the price registry was missing data.

Adds the field to 19 vertex_ai/claude-* entries across both
`model_prices_and_context_window.json` and the bundled
`model_prices_and_context_window_backup.json`:

  - Haiku 4.5 ($1.25 -> $2.00 / MTok)
  - Sonnet 3.7 / 4 / 4.5 / 4.6 ($3.75 -> $6.00 / MTok)
  - Opus 4.5 / 4.6 / 4.7 ($6.25 -> $10.00 / MTok)
  - Opus 4 / 4.1 ($18.75 -> $30.00 / MTok)

Adds `tests/test_litellm/test_vertex_anthropic_1hr_cache_pricing.py`
mirroring the Bedrock equivalent — pins each (5m, 1h) pair per model
and asserts the 1.6x ratio across the family.

Fixes #27781.

* Fix Gemini multimodal function responses (#29325)

Co-authored-by: yuneng-jiang <yuneng@berri.ai>

* address greptile review: add _transform_image_usage method and model-map supports_image_size flag

- Add _transform_image_usage instance method to GoogleImageGenConfig that
  delegates to transform_gemini_image_usage, fixing the regression test
- Replace hardcoded "2.5-flash" string check in supports_gemini_image_size
  with a get_model_info lookup on supports_image_size (default true)
- Add supports_image_size: false to all gemini-2.5-flash model entries in
  model_prices_and_context_window.json so capability is controlled via the
  model map rather than embedded in code

* fix test failures: schema validation, mypy type, model info plumbing, pricing test

- Add supports_image_size to ModelInfoBase TypedDict so get_model_info surfaces it
- Pass supports_image_size through _get_model_info_helper constructor call
- Fix supports_gemini_image_size to use value is not False (None means unset, defaults to True)
- Add supports_image_size to JSON schema in test_aaamodel_prices_and_context_window_json_is_valid
- Correct gemini-3.1-flash-lite pricing assertions in test to match JSON values

* Add Azure AI Kimi K2.6 metadata (#27052)

* Add Azure AI Kimi K2.6 metadata

* Scope Kimi metadata test cost map setup

* fall back to substring check for models not in model_prices_and_context_window.json

Models like gemini-2.5-flash-image-preview are not in the pricing JSON,
so get_model_info raises. Fall back to "2.5-flash" not in model when the
JSON has no explicit supports_image_size entry for the model.

* fix(inception): don't forward global litellm.api_key to Inception FIM

Match the Inception chat config: resolve only an Inception-specific key
(param, litellm.inception_key, or INCEPTION_API_KEY) for the text-completion
FIM path. The global litellm.api_key (often an OpenAI key) was both leaking
to api.inceptionlabs.ai and taking precedence over the configured Inception
key when set.

* fix(auth): enforce end-user budget on custom-auth path that skips common_checks

get_end_user_object() no longer raises BudgetExceededError, so custom-auth
deployments with custom_auth_run_common_checks unset (which skip the
centralized common_checks gate) stopped enforcing the end-user budget,
letting an over-budget end user keep making requests. Re-enforce the
budget in _run_post_custom_auth_checks on that path.

fix(key_generate): allow team members to create keys on org-scoped teams (#29310)
* fix(key_generate): allow team members to create keys on org-scoped teams

When a virtual key is created for a team, enterprise logic inherits the
team's organization_id onto the key (add_team_organization_id). Since the
VERIA-55 org-IDOR fix, /key/generate then required the caller to be an
explicit LiteLLM_OrganizationMembership member of that org, returning
403 "Caller is not a member of organization_id=<uuid>". Admins normally
only add users to teams (not orgs), so self-serve key creation regressed
for any user on an org-scoped team (regression since v1.84.0-rc.1).

Skip the org-membership check when organization_id was inherited from the
key's team (organization_id == team_table.organization_id). Team-level
authorization already gates this path, so team membership is sufficient.
The membership check still runs when a caller assigns an organization_id
that did not come from the key's team, preserving the IDOR protection.

Adds regression tests covering both the team-inherited (allowed) and
foreign-org (still blocked) cases.

* test(key_generate): cover mismatched team org IDOR path on generate

Add test_generate_key_foreign_org_with_mismatched_team_still_enforces_membership
for the case where a team is present but request organization_id differs from
team_table.organization_id. Enterprise inheritance is no-op'd in the test so
the guard is exercised directly; membership validation must still run.

Addresses Greptile review on #29310.

fix(auth): let internal users view search tools (#29542)
* fix(auth): let internal users view search tools

Internal users could not see search tools in the UI even when an admin
created them, while vector stores were visible. The Search Tools page
rendered but its list calls 403'd because the read routes were not in
internal_user_routes. Grant internal users read-only access to the
listing and provider routes; create/update/delete stay admin-only.

Resolves LIT-3150

* fix(auth): scope /search_tools/list to caller-allowed tools

Adding the read routes to internal_user_routes let any internal user
call /search_tools/list, which returned every configured tool's id,
provider, api_base, and metadata regardless of the caller's
object_permission.search_tools allowlist. The api_key was masked, so
this was metadata disclosure rather than a credential leak, but it
ignored the key/team scoping that /search already enforces.

Filter the listing through the same can_key_call_search_tool /
can_team_call_search_tool checks (exposed as a boolean
can_user_view_search_tool), so non-admin callers only see tools they
may invoke; admins still see all. Mirrors how /vector_store/list
scopes results.

* fix(types): resolve mypy errors in list_search_tools

The config and DB build loops reused one loop variable, so mypy pinned
it to the config element type (SearchToolTypedDict); its .get() calls
returned object and the DB element (SearchTool) failed the reuse
assignment. Give each loop its own variable so each gets its real type,
and coerce the config tool's SearchToolInfoTypedDict to a plain dict to
match SearchToolInfoResponse.search_tool_info.

test(proxy/utils): pin ProxyLogging behavior (#29485)
* test(proxy/utils): pin ProxyLogging behavior

Add behavior-pinning tests for the ProxyLogging cluster in
litellm/proxy/utils.py under tests/test_litellm/proxy/utils/proxy_logging/.
Covers InternalUsageCache, _CallbackCapabilities, top-of-file helpers
(print_verbose, _get_email_logger_class, _accepts_litellm_call_info,
_enrich_http_exception_with_guardrail_context), the full ProxyLogging
class (lifecycle, MCP-LLM bridging, capability probes, guardrail
pipeline, pre/during/post/streaming hooks, alerting), plus the
bottom-of-region helpers (on_backoff, jsonify_object, _lookup_deprecated_key).

Each pinned symbol has happy-path and error-path coverage; happy paths
use direct dict-equality with three or more keys (or HiddenParams /
Pydantic model_validate where the surface is a Pydantic shape). The
subdirectory carries a local _pin_check.py and _coverage_check.py that
enforce the gate without surfacing numeric thresholds in CI logs.

Wires tests/test_litellm/proxy/utils into the existing test-path block
in .github/workflows/test-unit-proxy-endpoints.yml.

* test(proxy/utils): drop unused mock_httpx_client fixture

Declared in conftest.py but never referenced by any test. Removing
the dead fixture per Greptile P2 feedback.

* test(proxy/utils): drop local-only gate scripts from PR

_pin_check.py and _coverage_check.py are local stopping signals (not
wired into CI, consume a gitignored .pin_list.txt). They served their
purpose telling the engineer when to stop writing tests; the pytest
suite is the artifact that belongs in the repo.

test(proxy/utils): pin PrismaClient and spend-update behavior (#29488)
* test(proxy/utils): pin PrismaClient and spend-update behavior

PR2 of the litellm/proxy/utils.py behavior-pinning plan
(https://www.notion.so/37343b8acdab81f68f39f66915f62bcf). Adds
tests/test_litellm/proxy/utils/prisma_and_spend/, with happy + error
pins for every symbol in the PR2 list: the config-param cache,
PrismaClient lifecycle/data ops/engine watcher/reconnect/health
clusters, the user-row cache and SMTP helper, password/token helpers,
ProxyUpdateSpend, and the module-level spend functions.

Tests run against fully-mocked Prisma stacks (patched ``Prisma`` /
``PrismaWrapper`` at fixture setup), with a fake SMTP transport and a
clock-driven asyncio.sleep for the monitor loop, so unit runs need no
DB or network. ``_pin_check.py`` enforces happy + error coverage for
every symbol; ``_coverage_check.py`` filters branch + line coverage to
the PR2 source range (lines 2,668-5,541) and prints PASS / FAIL with
no numbers. Workflow shard ``tests/test_litellm/proxy/utils`` is added
to the existing proxy-endpoints job.

* test(proxy/utils): commit pin list and drop dead exclusion line

Addresses Greptile review feedback on PR #29488:
  - Check in ``.pin_list.txt`` (force-added, overriding the repo-wide
    ``.gitignore`` rule) so reviewers can reproduce the ``_pin_check.py``
    PASS shown in the PR description without first regenerating the
    file from Notion.
  - Remove the unreachable ``_harness_smoke_test.py`` continue in
    ``_pin_check.py``: the surrounding ``test_*.py`` glob already
    excludes underscore-prefixed files; rephrase the docstring instead.

* test(proxy/utils): shift PR2 coverage line range by +1 after merge

``litellm_internal_staging`` added one line in ``ProxyLogging`` at
``utils.py:645`` (PR1 territory, before the PR2 region). Bump the
``_PR2_LINE_START`` / ``_PR2_LINE_END`` constants accordingly so the
coverage gate keeps scoring the same source region after the merge.

* test(proxy/utils): drop committed pin-list and gate scripts

``_pin_check.py``, ``_coverage_check.py``, and ``.pin_list.txt`` are
local-only stopping signals: no workflow or pytest collection invokes
them, so committing them adds rot risk (line-range drift in the
coverage check, pin-list staleness) without any enforcement upside.

The pin-list contract lives in the Notion plan; the tests themselves
are the durable artifact.

* test(proxy/utils): apply greptile fixes to behavior-pinning gates

Address findings from the sibling PR1/PR2 greptile reviews that also
apply to this PR:

- Commit pin_list.txt alongside the gate script (was previously a
  gitignored .pin_list.txt fetched from Notion). The gate is now
  reproducible without out-of-band setup.
- Resolve the coverage region by locating the first pinned symbol's
  def line in litellm/proxy/utils.py at runtime, instead of hardcoded
  line numbers that drift when lines above shift.
- Word-boundary the pin reference check so pins like update_spend do
  not falsely match update_spend_logs_job.
- Drop the dead _harness_smoke_test.py exclusion; the test_*.py glob
  already filters underscore-prefixed files.

* test(proxy/utils): drop local-only stopping-signal scripts

Remove _pin_check.py, _coverage_check.py, and pin_list.txt. These were
dev-time tooling for knowing when test authoring was done; they are
not wired into CI and the test files themselves are the merge artifact.

fix(otel): capture 401 error details in management endpoint spans (#29535)
Auth failures on management endpoints such as team/list and
organization/list (invalid or expired keys) were raised as
ProxyException, whose __str__ returned an empty string, so the OTEL
SERVER span recorded an error with no message. ProxyException now
stringifies to its message, get_error_information prefers the explicit
.message attribute, and the proxy exception handlers stamp a consistent
error.type, error.code and error.message on the span

Resolves LIT-3515

fix(auth): preserve 401 status for expired JWTs in OTel traces (#29510)
* fix(auth): preserve 401 status for expired JWTs in OTel traces

Expired JWT access tokens raised a generic Exception with no status
code attached. Because the codeless exception was logged to OTel via
post_call_failure_hook before auth_exception_handler re-wrapped it as
ProxyException(401), the OTel span never set http.response.status_code
and trace viewers displayed it as a generic 500. Clients still got a
401 back, so traces and actual responses diverged.

Raise ProxyException(code=401, type=expired_key) directly at the source
in both JWT decode paths so the 401 is consistent across the client
response and the OTel http.response.status_code attribute, matching how
virtual-key expirations are handled.

* fix(auth): preserve 401 for expired JWTs on issuer-scoped path

The issuer-scoped JWT path (_auth_jwt_with_issuer) still raised a generic
Exception on expiry, surfacing as a 500 in client responses and OTel traces.
Raise ProxyException with expired_key/401 there too, matching auth_jwt, and
add a regression test exercising the issuer path end-to-end

feat(agents): add LangFlow agent provider with A2A session bridging (#28963)
* feat(agents): add LangFlow agent provider with A2A session bridging

Register LangFlow as a completion provider and agent type (UI + /api/v1/run),
and map A2A contextId to LangFlow session_id for multi-turn conversations.

* docs(providers): document langflow in provider_endpoints_support.json

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(agents): address Greptile review for LangFlow integration

Move A2A contextId→session_id mapping into LangFlow A2A provider config,
add langflow.svg logo, remove live integration test, use model for token count.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(langflow): prevent flow_id override via request optional_params

Derive flow_id only from the authorized model name and reject flow_id
kwargs so callers cannot invoke a different LangFlow run endpoint.

Co-authored-by: Cursor <cursoragent@cursor.com>

* refactor(langflow): remove redundant flow_id branch in _get_flow_id

* fix(langflow): surface an error when the run response has no extractable message

Previously the response parser returned the raw JSON blob as the assistant
message when it could not find message text, silently presenting an
unparseable payload as a valid answer. It now returns None and the caller
raises a LangFlowError so the failure is visible to the client.

* fix(langflow): URL-encode flow_id path segment to prevent path injection

flow_id is taken from the model suffix and interpolated into
/api/v1/run/{flow_id}. Without path-segment encoding a model such as
langflow/../../x (or one containing ?) could move the request off the run
endpoint to another path on the configured LangFlow server using the
operator x-api-key. Encode the segment with quote(safe="") so it always
stays a single path segment.

* fix(langflow): reject empty flow_id from model name

* fix(langflow): return stripped flow_id so validation matches URL path

* fix(langflow): reject caller-supplied tweaks to prevent flow component override

* fix(langflow): reject caller-supplied tweaks injected via extra_body

The transform_request guard only inspected optional_params, but extra_body
is popped before transform_request runs and merged into the request body
afterward, letting a caller reintroduce tweaks and override the
operator-configured LangFlow flow components. Validate the final request
body in sign_request so tweaks cannot reach LangFlow through extra_body.

* test(langflow): move provider tests into mirrored coverage path

The langflow tests lived under tests/llm_translation/, whose CircleCI job
runs without --cov and uploads nothing to Codecov, so none of the new
langflow code counted toward patch coverage (codecov/patch reported 9.78%
of the diff hit against a 70.83% target).

Relocate them to tests/test_litellm/llms/langflow/, which the GitHub
Actions provider job runs with --cov=./litellm and uploads, and add
regression tests for the previously untested happy paths (transform_response
building the ModelResponse with usage, non-JSON body handling, last-user
message extraction, outputs-dict response shape, sign_request pass-through,
error class and stream flags). Patch coverage on the diff is now ~88%.

* fix(langflow): require litellm_params in A2A config instead of silent empty fallback

* fix(langflow): scope A2A session_id to the authenticated key

The LangFlow A2A bridge used the LangFlow session_id verbatim from the
client-controlled A2A contextId, so two distinct virtual keys authorized for
the same agent could read or append to each other's LangFlow conversation
memory by reusing a contextId.

Hand the authenticated key hash to the completion bridge through litellm_params
and namespace the forwarded session_id with it. The same key keeps a stable
session across turns, while different keys can no longer collide on a shared
contextId. The principal is hashed before it is embedded in the session_id, so
the stored token is never sent to the LangFlow backend; the original contextId
is preserved as a suffix for operator-side correlation.

* fix(langflow): wire authenticated key hash through A2A bridge and tests

Define A2A_USER_API_KEY_HASH_PARAM in the completion bridge handler, strip it
before litellm.acompletion, inject the authenticated key hash at the proxy A2A
endpoint, and add regression tests for per-key LangFlow session scoping.

feat(proxy): add per-MCP-server RPM rate limiting for keys and teams (#29482)
* feat(proxy): add per-MCP-server RPM rate limiting for keys and teams

Adds mcp_rpm_limit, a dict keyed by MCP server name (alias if set, else the
configured name) that caps requests per minute per server for a key or team.
The v3 rate limiter builds a per-server descriptor only when a limit is
configured for the server being called, so other servers stay uncapped and no
TPM reservation is engaged. Server identity is surfaced into the request data
via mcp_rate_limit_server_name so the limiter can resolve it.

* fix(proxy): gate MCP rpm descriptors on call_mcp_tool; document mcp_rpm_limit param

Only honor mcp_server_name when the call is an actual MCP tool call. Without
this, a normal LLM request could inject mcp_server_name in its body to consume
a target server's MCP quota and 429 legitimate tool calls. Also adds the
mcp_rpm_limit parameter docstring to update_key, new_user, and user_update so
the API docs validator passes.

* Fix MCP rate limit quota handling

* Delete scripts/test_mcp_rpm_limit.sh

* docs(proxy): clarify mcp_rpm_limit is enforced for keys and teams, not per user

* fix(proxy): accept mcp_rpm_limit in generate_key_helper_fn

NewUserRequest and GenerateKeyRequest inherit mcp_rpm_limit from
GenerateRequestBase, so /user/new and /key/generate forwarded the field
to generate_key_helper_fn, which did not accept it and returned a 500
("unexpected keyword argument 'mcp_rpm_limit'"). Accept the param and
store it in metadata, matching model_rpm_limit/model_tpm_limit, so the
limit is persisted where get_key_mcp_rpm_limit reads it.

[internal copy of #28008] Support MCP OAuth passthrough and issuer-scoped JWT auth (#28356)
* fix(proxy): point /metrics 401 at the opt-out flag

Operators upgrading past 35bbca60b0 (which made /metrics auth
default-on) see "Malformed API Key passed in. Ensure Key has 'Bearer '
prefix." with no hint that
litellm_settings.require_auth_for_metrics_endpoint: false restores the
previous unauthenticated behavior. Append that discovery hint to the
existing 401 body so a Prometheus scraper that breaks after upgrade
has a clear migration path. No behavior change.

* fix(proxy): bound budget reservation per request instead of pinning to remaining headroom

reserve_budget_for_request fell back to reserving the entire remaining
team/key/user headroom whenever a request omitted max_tokens, which
pinned the spend counter at max_budget for the duration of the
in-flight request and false-positive-blocked every concurrent or
back-to-back request until the success callback reconciled. Surfaced
as an integration-test team being budget-blocked at its $2000 cap
while DB spend was $0.144.

Switch the missing-max_tokens path to a fixed default of 16384 output
tokens (mirrors parallel_request_limiter_v3's DEFAULT_MAX_TOKENS_ESTIMATE
precedent), and clamp explicit max_tokens at the model's
max_output_tokens for reservation accounting only. The outbound request
body is unchanged, so providers see whatever the caller actually sent;
only the local integer used to compute reservation cost is bounded.
This also prevents a hostile max_tokens=999999999 from inflating one
request's reservation up to the entire team headroom.

For Opus 4.7 (output $25/M, max_output 128K) on a $2000 budget the
worst-case per-request reservation drops from "everything left" to
$3.20, raising admittable concurrency from 1 to ~625.

* fix(proxy): reserve per-image cost for image-generation requests

Image-generation routes (dall-e-3, flux, etc.) have no per-token output
cost so they fell through to the no-reservation read-time-only path.
Concurrent image requests against a depleted budget could all pass
common_checks (counter exactly at max_budget passes the strict-`>`
gate) and reach the provider before reconciliation caught up.

Add per-image reservation in _estimate_request_max_cost_for_model:
when the model has a per-image cost field, reserve `n × cost_per_image`
upfront. The atomic counter increment serializes concurrent admissions,
so the second request sees the post-first-reservation counter and
raises BudgetExceededError instead of silently leaking through.

Both `output_cost_per_image` and `input_cost_per_image` are honored —
naming is inconsistent across providers (OpenAI dall-e-3 uses
input_cost_per_image, aiml/dall-e-3 uses output_cost_per_image for
the same per-generated-image price).

Per-pixel pricing (DALL-E 2 size variants) and TTS/STT routes still
fall through to read-time enforcement; those are follow-ups.

* fix(proxy): gate image-gen reservation strictly on model mode

The previous detection treated any model with input_cost_per_image
or output_cost_per_image as image generation. Several chat and
embedding models carry those fields to price multimodal vision input,
not generated images:

- gemini-3.1-pro-preview (mode=chat) has output_cost_per_image=0.00012
  alongside input/output token pricing.
- azure/gpt-realtime-* (mode=chat) has input_cost_per_image=5e-6.
- amazon.titan-embed-image-v1 (mode=embedding) has
  input_cost_per_image=6e-5.

For these models the image-gen branch fired first and reserved a
fraction of a cent per request, short-circuiting the token-priced
path entirely. Long Gemini chats reserved 1 × $0.00012 instead of
the true token cost.

Gate strictly on mode in {"image_generation", "image_edit"}. All 197
real image_generation entries and all 31 image_edit entries
(Flux Kontext, Stability inpaint/outpaint, etc.) carry the right mode,
so the field-presence fallback was unnecessary.

Adds regression tests for the chat-model-with-image-cost-field case
and for image_edit reservation.

* build(packaging): relax core runtime pins to ranges

Backport of #27241 onto litellm_1.84.0rc2.

The 12 entries in `[project.dependencies]` were exact `==` pins, a side
effect of the Poetry -> uv migration. This forces every downstream
package that lists litellm as a dependency to downgrade common runtime
libraries (openai, pydantic, aiohttp, click, jsonschema, ...) to the
exact versions we ship.

Switch to lower-bounded ranges with upper bounds where the upstream
package is pre-1.0 or has a known breaking-major-version policy.
Reproducibility for our Docker proxy and CI continues to come from
`uv.lock`, which is regenerated here as a metadata-only diff.

Conflict resolution vs upstream merge:
- The upstream merge commit also surfaced unrelated context entries
  (nvidia-riva-client, soundfile/stt-nvidia-riva extra) that exist in
  staging but not in rc2. Those are not part of #27241's intent and
  were dropped from the resolution; the rc2 uv.lock keeps its existing
  entry set, only the 12 specifier strings changed.
- `uv lock --check` passes (392 packages resolved, no drift).

* build(packaging): raise jinja2 floor to 3.1.6

Our `uv.lock` already resolves jinja2 to 3.1.6, so Docker / CI installs
get that version. The `pyproject.toml` floor was lagging at 3.1.0,
which means downstream consumers using `--resolution=lowest-direct` or
older constraint files can land on 3.1.0-3.1.5 instead of the version
we actually test against.

Aligns the declared floor with the resolved version so external
installers see the same baseline our test matrix exercises.

`uv lock` diff is metadata-only (no resolved-version drift).

* fix(mcp): forward extra_headers for OpenAPI MCP tools

OpenAPI-generated tools only applied static closure headers and BYOK
Authorization via ContextVar. Copy MCPServer.extra_headers from the
incoming MCP request into _request_extra_headers (set in server.py before
local tool dispatch), merge in openapi_to_mcp_generator via a small helper.

OAuth2 M2M: do not forward caller Authorization from raw_headers (same rule
as _prepare_mcp_server_headers for managed MCP).

Adds TestRequestExtraHeaders and clarifies mcp_server_manager registration
comment.

* refactor(mcp): access has_client_credentials on MCPServer directly

Greptile: getattr default was redundant; property exists on MCPServer and
mcp_server is non-None inside the extra_headers forwarding block.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(mcp): static headers win over forwarded headers in OpenAPI MCP

Match the existing MCP invariant in merge_mcp_headers and the managed MCP
path: operator-configured static headers always override caller-forwarded
headers on name conflict, with case-insensitive comparison so different
casing cannot bypass the precedence. _request_auth_header (BYOK) still
overrides Authorization last.

Addresses Veria review on PR #27383.

* fix(proxy): always merge caller-supplied tags into request metadata

Caller-supplied tags (`x-litellm-tags` header, body `tags`, `metadata.tags`)
were silently dropped unless the key/team had
`metadata.allow_client_tags: true` set. Restore the documented behavior:
tags from the request always flow into `metadata.tags` and union with any
admin-configured static tags from key/team/project metadata.

Removes the `allow_client_tags` opt-in flag from the pre-call pipeline.
The flag was only ever read here; it has no schema or endpoint footprint,
so leftover values in existing key metadata are inert.

Test cleanup mirrors the simplification: drop the three tests that
verified the strip-when-not-opted-in path, drop the `allow_client_tags`
fixture lines from the merge/union tests.

* docs(proxy): refresh stale comments referencing removed tag strip

The tag-strip block was removed in the parent commit but two surrounding
comments still referenced "tags without opt-in" and "runs AFTER the
strip". Update them to describe the remaining user_api_key_* and
_pipeline_managed_guardrails strip that the snapshot/merge ordering
actually protects against.

* Strip SERVER_ROOT_PATH before lazy-feature prefix match

LazyFeatureMiddleware compared the raw scope path against registered
prefixes (e.g. /policies), so requests under a server root path like
/api/v1/policies/... never matched, the feature never loaded, and the
endpoint returned 404. Strip the configured root path before matching,
normalizing trailing slashes and enforcing a component boundary so
/api does not falsely match /apiv2.

* Cache normalized SERVER_ROOT_PATH at middleware init

SERVER_ROOT_PATH is a process-startup env var. Read it once in
__init__ instead of calling get_server_root_path() + rstrip on every
request that arrives before all lazy features have loaded.

* chore(proxy): backport /key/regenerate ownership-rebind + premium-gate guards (#27793)

Backport of #27793 onto litellm_1.84.0rc2.

A non-admin caller could rebind their own key's user_id via /key/regenerate.
_execute_virtual_key_regeneration had org/team guards but no user_id guard,
and prepare_key_update_data did not strip the field — it survived
model_dump(exclude_unset=True) into the Prisma update. On the next request,
_return_user_api_key_auth_obj resolved the rebound user_id against
litellm_usertable and returned PROXY_ADMIN whenever the target row's
user_role was admin.

/key/update had the equivalent guard inline at _validate_update_key_data;
extract it to a shared helper _validate_caller_can_change_key_ownership and
call from both /key/update and _execute_virtual_key_regeneration.

Also tighten the premium gate that allowed the master-key rotation branch to
skip the enterprise check. The previous predicate was a field-presence test,
not an identity check. Verify the caller actually holds the master key via
_is_master_key before allowing the non-premium path.

Block explicit-null user_id and empty-string user_id as removal attempts;
both 403-reject for non-admin callers.

* fix(proxy): expose db status on public /health/readiness

Backport of #27866 onto litellm_1.84.0rc2.

External readiness probes consumed the legacy detailed payload's `db`
field to drive alerting and pod-rotation decisions. Stripping the body
to {"status": "healthy"} broke those probes silently — the HTTP code
still flipped to 503, but probes checking body.db == "connected"
treated the response as healthy.

Add `db` back to the unauthenticated payload. The rest of the diagnostic
fields (litellm_version, callbacks, cache, log_level) stay behind
/health/readiness/details so the recon-leak gate from #26912 holds.
Values match the legacy contract: "connected", "disconnected",
"Not connected". The 503-on-DB-disconnect behavior from LIT-2607 is
preserved.

* fix(ui): fetch version + debug flag from /health/readiness/details

The proxy moved `litellm_version`, `is_detailed_debug`, and other
diagnostic fields off the public `/health/readiness` payload behind
an auth-gated `/health/readiness/details` endpoint. The navbar
version tag and the detailed-debug-mode banner stopped working
because they were still reading those fields from the unauthed
response, which no longer contains them.

Replace `useHealthReadiness` with a `useHealthReadinessDetails`
hook that takes an `accessToken` argument and sends a Bearer header
to the auth-gated endpoint. The hook stays disabled while
`accessToken` is falsy, so the navbar can keep rendering on the
public model hub (where the token is null) without triggering an
auth redirect or a 401-loop.

* fix(ui): disable retries on readiness/details + cover token forwarding

Two small follow-ups on the readiness/details migration:

- Set `retry: false` on the query. The payload feeds a passive
  navbar tag and a debug banner; a 401 from an expired token
  shouldn't fan out into three retries against the proxy.
- Add navbar specs that assert the `accessToken` prop is forwarded
  into the hook (matches the DebugWarningBanner spec). Without
  this, the navbar could silently regress to passing `undefined`
  and the existing tests wouldn't catch it.

* fix: block client-side pricing injection via request body

Authenticated clients could supply CustomPricingLiteLLMParams fields
(input_cost_per_token, output_cost_per_token, etc.) in the request body.
These were forwarded to register_model() in main.py, permanently mutating
the shared global litellm.model_cost dict for all users on the instance.

Adds all CustomPricingLiteLLMParams fields to _BANNED_REQUEST_BODY_PARAMS
so is_request_body_safe() rejects them before they reach completion().
New pricing fields added to CustomPricingLiteLLMParams are auto-covered.

Admin opt-in via allow_client_side_credentials or
configurable_clientside_auth_params still works as before.

* fix: block SSRF fields in RAG ingest vector_store config

aws_sts_endpoint, aws_web_identity_token, and aws_bedrock_runtime_endpoint
in ingest_options.vector_store were passed directly to the Bedrock ingestion
class, which reads them into boto3 STS client construction. Any authenticated
caller could redirect AssumeRole calls to an attacker-controlled server,
leaking the proxy's instance profile credentials.

Calls is_request_body_safe() on ingest_options["vector_store"] before
forwarding to litellm.aingest(). Same banned-params list and admin opt-in
escape hatch (allow_client_side_credentials) as the /chat/completions path.
ValueError from the safety check is caught and re-raised as HTTP 400.

* fix: harden /key/update authorization checks (#27878)

* fix: patch Host-header auth bypass in get_request_route

Starlette reconstructs request.url from the Host header. A malformed
Host like `localhost/?x=1` causes Starlette to build the full URL as
`http://localhost/?x=1/health`, which url-parses to path="/". Since "/"
is in LiteLLMRoutes.public_routes, all protected routes became reachable
without authentication.

Fix: read scope["path"] (set by uvicorn from the HTTP request line,
not derivable from headers) instead of request.url.path. Sub-path
deployments are handled via scope["app_root_path"] / scope["root_path"],
mirroring Starlette's own base_url construction logic.

Affected variants confirmed fixed:
  Host: localhost/?x=1
  Host: localhost:4000/?x=1
  Host: localhost/#test
  Host: localhost:4000/#test

* fix: block credential fields in RAG ingest vector_store options

Credential fields (vertex_credentials, aws_access_key_id, api_key, etc.)
in ingest_options.vector_store are now rejected at the API boundary with
a 400 error. Credentials must be configured server-side.

Previously any authenticated user could supply a vertex_credentials dict
with type=external_account pointing credential_source.file at an
arbitrary path (e.g. /proc/1/environ) and token_url at an
attacker-controlled server. google-auth's identity_pool.Credentials
refresh() would read the file and POST its contents to the attacker.

* fix: block /key/update self-escalation by assigned users

Non-admin users who were assigned a key (created_by != caller) could
update any non-budget field — models, rpm_limit, guardrails, etc. —
without admin authorization, allowing privilege self-escalation.

Gate: only the key creator (created_by == caller) may edit their own
key without admin check; budget changes always require admin regardless
of creator status. All other callers must pass _check_key_admin_access.

* fix: block SSRF via api_base in /prompts/test dotprompt YAML frontmatter

Any frontmatter key not in ["model","input","output"] flowed into
optional_params and was merged into the LLM call data dict, bypassing
is_request_body_safe. An attacker with any bearer key could set
api_base in YAML to redirect the outbound LLM request — including the
provider API key — to an attacker-controlled host.

Fix: call is_request_body_safe on the constructed data dict after
optional_params are merged, before invoking ProxyBaseLLMRequestProcessing.
ValueError from the banned-param check is surfaced as HTTP 400.

* fix: coerce nested config strings before banned-param check

_NESTED_CONFIG_KEYS descent used isinstance(nested, dict) which silently
skipped litellm_embedding_config when delivered as a JSON string via
multipart/form-data. Banned params (api_base, aws_sts_endpoint, etc.)
nested inside the stringified value were invisible to is_request_body_safe.

_NESTED_METADATA_KEYS already used _coerce_metadata_to_dict which parses
JSON strings before checking. Apply the same coercion to _NESTED_CONFIG_KEYS.

* fix: replace substring match with prefix match in is_llm_api_route

mapped_pass_through_routes used `_llm_passthrough_route in route` (substring)
so any admin-only path whose URL contained a provider name (openai, anthropic,
azure, bedrock, etc.) was misclassified as an LLM API route and bypassed the
admin gate in non_proxy_admin_allowed_routes_check.

Confirmed live: non-admin key could GET /credentials/by_name/openai (read
masked provider API key) and DELETE /credentials/openai (delete credential).

Fix: use exact match or startswith(prefix + "/") — the same pattern used
everywhere else in RouteChecks — so only routes that actually start with a
passthrough prefix are allowed through.

* fix: stabilize PR #27878 test failures

- key_management_endpoints: extend can_skip_admin_check to team keys so
  team members with /key/update permission can update non-budget fields.
  can_team_member_execute_key_management_endpoint already validates team
  membership + permission and raises if unauthorized; reaching the admin
  check on a team key means the caller was authorized.

- test: set created_by on mock key in
  test_update_key_non_budget_fields_allowed_for_internal_user so
  caller_is_creator resolves correctly (MagicMock default ≠ user_id).

- auth_utils.get_request_route: guard against non-dict request.scope
  (e.g. MagicMock in unit tests) to prevent a MagicMock leaking into
  UserAPIKeyAuth.request_route and failing Pydantic validation.

- ci: assign test_multipart_bypass_repro.py to the proxy-runtime shard
  in test-unit-proxy-db.yml to satisfy the shard-coverage check.

* fix(lint): add explicit str() cast in get_request_route for MyPy

scope.get() returns Any|None which MyPy cannot coerce to str implicitly.
Wrap both scope.get() calls in str() to satisfy the type checker.

* fix: guard bare-/ root_path strip + make total_spend migration idempotent

auth_utils.get_request_route: when Starlette sets scope["app_root_path"]
to "/" (e.g. behind some middleware), the old stripping logic would
remove the leading slash from every path ("/team/new" → "team/new"),
breaking route matching and causing auth to misclassify protected routes.
Skip stripping when root_path is bare "/".

migration: add IF NOT EXISTS to total_spend ALTER TABLE so the migration
is safe to replay when a prior partial run already created the column.
Without this guard, prisma migrate deploy fails on CI DBs that were
partially migrated, causing all subsequent DB operations (including
/team/new) to 500.

* fix: require creator still owns key for personal-key bypass in /key/update

caller_is_creator now requires both created_by == caller AND user_id ==
caller. Previously checking only created_by let a demoted admin who
originally created a key for another user continue editing non-budget
fields on it after reassignment, bypassing _check_key_admin_access.

Adds regression test: creator whose key was reassigned is blocked (403).

* fix: extract auth checks to fix PLR0915 + broaden max_budget assertion

internal_user_endpoints._update_single_user_helper exceeded 50 statements
(PLR0915). Extract authorization checks into _check_user_update_authz helper
to bring statement count under the limit.

test_validate_max_budget: assert "negative" (substring of both the local
"cannot be negative" and the CI "non-negative finite number" messages) so
the test is stable regardless of which exact wording the function uses.

- Strip Authorization header from extra_headers for pass-through servers
- Pass-through servers (auth_type=None with extra_headers: [Authorization])
  must not receive the user's LiteLLM API key
- Only OAuth2 M2M and pass-through servers skip Authorization header
- Other headers (x-request-id, x-trace-id) are still forwarded normally
- Fixes credential leakage / authentication bypass in MCP pass-through mode

* fix(interactions): remove steps field not in google openapi spec

The steps field was added but is not present in the current Google
Interactions OpenAPI specification. Revert to using only the fields
that are actually defined in the spec.

* fix(mcp): forward Authorization in pass-through when x-litellm-api-key is admission

Commit 3753970cc9 widened the Authorization strip to cover all
is_oauth_passthrough servers — protecting against the LiteLLM admission
key leaking upstream when the caller used Authorization for admission,
but also silently stripping legitimate upstream OAuth bearers when the
caller used x-litellm-api-key for admission.

That broke transparent OAuth pass-through (EAI-506 V5/V6): standards-
compliant MCP clients (OpenCode, Claude Code, mcp-inspector) complete
PKCE against the upstream IdP and send the resulting token as plain
Authorization: Bearer per the MCP spec — with the wider strip in place,
that token never reaches the upstream and tools/list returns empty.

Narrow the strip: skip Authorization for pass-through servers only when
the caller did NOT supply x-litellm-api-key. When x-litellm-api-key is
present, admission is unambiguous and Authorization is free to carry
the upstream OAuth bearer.

The original security guarantee is preserved — a client that sends only
Authorization (no x-litellm-api-key) still has it stripped, so the
LiteLLM key cannot leak upstream via that path.

Tests:
- new: forwards Authorization when x-litellm-api-key is present
- new: still strips Authorization when only Authorization is present
- existing pass-through + M2M tests unchanged

* fix(interactions): align status enum with openapi spec

* fix(mcp,jwt): address greptile review concerns

- Cache _get_agent_object_permission via user_api_key_cache (sentinel for

  every tool-list / tool-call.
- Re-raise HTTPException in handle_sse_mcp so 401 + WWW-Authenticate
  challenges (and other HTTP errors) propagate to SSE clients instead of
  being swallowed as 500.
- Normalise booleans in _validate_token_response so admin rules written as
  JSON-style "true" / "false" match upstream responses that return
  Python True / False.
- Treat configured JWT issuer claim mappings as advisory: when a mapped
  field is absent or empty, leave the normalised claim unset instead of
  raising, matching the global litellm_jwtauth path.

* test: replace dall-e-3 with gpt-image-1 in health check and router tests (#27813)

OpenAI returns 'The model dall-e-3 does not exist' for the test account,
breaking test_openai_img_gen_health_check and test_image_generation.
Switch to gpt-image-1, matching the existing TestOpenAIGPTImage1 pattern.

(cherry picked from commit aee58db880)

* fix(tests): drop dall-e-only test classes; route live image tests via gpt-image-1

Second wave of failures from the 2026-05-12 DALL-E shutdown:
- tests/image_gen_tests/test_image_edits.py::TestOpenAIImageEditDallE2
  and tests/image_gen_tests/test_image_generation.py::TestOpenAIDalle3
  are explicitly named for the deprecated models and can't pass; remove.
  gpt-image-1 coverage already exists in sibling classes.
- tests/local_testing/test_router.py image gen tests use dall-e-3 only
  as a routing example; swap to gpt-image-1.
- tests/local_testing/test_custom_callback_input.py image_generation
  success/failure paths swapped to gpt-image-1.

(cherry picked from commit 945b10ded4)

* test(fireworks): replace deprecated llama-v3p3-70b-instruct model

Fireworks removed llama-v3p3-70b-instruct from serverless, so every
live test using it now fails with NotFoundError ("Model not found,
inaccessible, and/or not deployed").

Swap the 6 references (3 files) to the currently-served
accounts/fireworks/models/deepseek-v3p1 — the canonical model in
Fireworks' current docs examples and present in LiteLLM's cost map.
test_get_model_params_fireworks_ai is a pure pricing-heuristic test
(no network) asserting the >16b branch, so it uses llama-v3p1-70b-
instruct instead to keep the "fireworks-ai-above-16b" assertion and
branch coverage intact.

(cherry picked from commit 39a1d438f2)

* test(fireworks): mock remaining live smoke tests

test_completion_fireworks_ai and test_completion_cost_fireworks_ai
made real Fireworks calls and broke whenever Fireworks rotated its
serverless catalog (no externally-verifiable model list exists).
They also asserted nothing — just printed.

Mock the HTTP post and assert real behavior instead: the request is
built with the right model/messages and the OpenAI-compatible
response parses back; the cost path yields a non-zero cost against
the local cost map. No network, no model dependency, stronger than
the old smoke checks.

(cherry picked from commit b5db7ed37d)

* fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5 (#28281)

* fix(tests): replace shut-down gpt-4o-audio-preview with gpt-audio-1.5

OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so the live audio
calls in test_stream_chunk_builder_openai_audio_output_usage and
test_standard_logging_payload_audio now hard-fail with a model-not-found
error on every PR. The error was not "openai-internal", so the except
block swallowed it and execution fell through to an unbound
completion/response (UnboundLocalError).

Switch both tests to gpt-audio-1.5, OpenAI's recommended successor
(GA, not deprecated, already present in the litellm cost map so the
response_cost assertion still resolves). Also broaden the except to
skip with the real error in the reason instead of crashing, so a
transient upstream blip can't reintroduce the UnboundLocalError.

* fix(tests): narrow audio-test skip to model-not-found, re-raise the rest

Address review feedback: an unconditional skip on any exception would
silently mask a litellm-internal regression in the audio path (broken
param transformation, serialization, bad header) instead of failing CI.

Skip only on the upstream-unavailable class (model_not_found / "does not
exist" / openai-internal) and re-raise everything else, so genuine
regressions still fail loudly. The UnboundLocalError is still fixed
because the handler either skips or raises - it never falls through.

* fix(tests): add budget_exceeded to expected Interaction status enum

Staging added budget_exceeded to the Interaction OpenAPI status enum; the staging merge into this branch picked up the spec change but not the matching test update, so test_status_enum_values failed in CI. Align the test's expected list (exact-match by design) with the live spec.

* fix(tests): mock HTTP fetch in test_img_url_token_counter

The test parameterized a live third-party image URL (blog.purpureus.net) which now 404s, causing get_image_dimensions to fall through to its base64 decode path and crash with 'not enough values to unpack' on every PR run. Mock safe_get with a tiny 1x1 PNG so the URL branch is still exercised without any network dependency.

* fix(tests): swap gpt-4o-audio-preview to gpt-audio-1.5 in test_gpt4o_audio

OpenAI shut down gpt-4o-audio-preview on 2026-05-07, so both live tests in test_gpt4o_audio.py (test_audio_output_from_model and test_audio_input_to_model) hard-fail model_not_found on every PR. Swap the hardcoded model to OpenAI's successor gpt-audio-1.5 (same chat-completions audio surface; already in the litellm cost map). Mirror the narrowed-skip pattern from the prior audio fixes: skip on model_not_found / does-not-exist / openai-internal, re-raise everything else so genuine litellm regressions still fail CI loudly.

(cherry picked from commit 92de7423ef)

* fix(tests): migrate realtime + rerank tests off shut-down upstream models (#28191)

* fix(tests): use gpt-realtime in realtime guardrails test

OpenAI shut down gpt-4o-realtime-preview-2024-12-17 on 2026-05-07, so
the live OpenAI realtime guardrails integration test now fails with
model_not_found (session.created never arrives, _wait_for_event times
out). Point OPENAI_REALTIME_URL at the current GA model, gpt-realtime.

Scope limited to this test: the pricing-catalog JSON keeps the retired
entries intentionally (historical cost calc + separate Azure timeline),
and the Azure realtime cost-calc test is unaffected.

* fix(tests): mock nvidia_nim rerank instead of hitting EOL'd endpoint

NVIDIA reached end-of-life for the hosted nvidia/llama-3.2-nv-rerankqa-1b-v2
rerank API on 2026-05-18 with no published replacement, so the live
BaseLLMRerankTest.test_basic_rerank for nvidia_nim now returns HTTP 410
("Gone"). NVIDIA's hosted catalog rotates on a schedule, so swapping in
another live model would only defer the failure.

Override test_basic_rerank in TestNvidiaNim to mock the sync/async HTTP
transport (same pattern as test_nvidia_nim_rerank_ranking_endpoint in this
file) and inject a fake NVIDIA_NIM_API_KEY via monkeypatch. The
request/response transformation and cost calculation stay covered offline.
Scope limited to nvidia_nim; other BaseLLMRerankTest providers untouched.

* fix(tests): migrate remaining realtime tests off shut-down gpt-4o-realtime-preview

OpenAI's 2026-05-07 shutdown removed the entire gpt-4o-realtime-preview
family, including the undated 'gpt-4o-realtime-preview' alias (not just the
dated snapshot fixed earlier). Three live tests still connected with the
dead alias and failed with messages_received=1 (an error event instead of
session.created):

- test_openai_realtime_simple.py: get_model() -> gpt-realtime (drives
  TestOpenAIRealtime.test_realtime_connection / test_realtime_with_query_params)
- test_openai_realtime.py: test_openai_realtime_direct_call_no_intent and
  test_openai_realtime_direct_call_with_intent -> openai/gpt-realtime
  (the with_intent test shares the same dead alias even though it was not
  in the failing set this run)

Mocked unit tests (test_realtime_query_params_construction,
test_realtime_query_params_use_normalized_model_name) are left as-is: they
never hit the network and assert string plumbing only.

Also fixes test_text_message_blocked_by_guardrail_no_ai_response, which now
connects (the earlier URL swap worked) but tripped a model-wording-brittle
assertion. The guardrail flow asks the model to voice the block message
verbatim; gpt-4o-realtime-preview complied (output contained 'blocked'),
gpt-realtime refuses verbatim-repeat instructions ('I'm sorry, but I can't
repeat that message.'). Since the original user message is blocked before
it reaches OpenAI, the refusal is still a safe outcome. Assertion #3 now
accepts both voicing and refusal, and adds a hard check that the blocked
phrase never leaks into AI output.

(cherry picked from commit ce87c411bf)

* fix(model_prices): register mistral/ministral-8b-2512

Mistral's API now returns model='ministral-8b-2512' when 'mistral-tiny'
is requested, so test_completion_mistral_api fails with 'This model
isn't mapped yet'. Adding the entry so completion_cost can resolve the
cost for that response.

Author: Claude <noreply@anthropic.com>

* fix(mcp,auth): address greptile review concerns

- handle_sse_mcp now calls _raise_preemptive_401_for_unauthenticated_servers
  so SSE clients to pass-through OAuth MCP servers receive the RFC 9728
  401 + WWW-Authenticate challenge that the streamable-HTTP path already emits.
- get_request_route strips a trailing slash from root_path before length-based
  prefix removal so non-canonical ASGI root_path values like "/litellm/"
  don't strip the leading slash from the returned route.
- _mcp_oauth_user_api_key_auth's cookie JWT decode now passes
  options={"verify_aud": False} so a future revision of the UI session
  JWT containing an aud claim cannot silently downgrade the request to
  unauthenticated.

* fix(tests): backfill local model_cost into remote-fetched map

litellm.model_cost is loaded at import time from LITELLM_MODEL_COST_MAP_URL
(pinned to main), so pricing entries that exist only in this branch (e.g.
mistral/ministral-8b-2512, freshly added because Mistral's API now returns
this id from mistral-tiny) are absent at test time and completion_cost
lookups raise 'This model isn't mapped yet'. Backfill the in-tree backup
into litellm.model_cost in the local_testing conftest so cassette-driven
cost calculations resolve against the entries that ship with the branch
under test.

Fixes local_testing_part1 failures on test_completion_mistral_api and
test_completion_mistral_api_modified_input.

* fix(mcp,jwt): address greptile concurrency and code-quality concerns

- _apply_issuer_claim_mappings now builds a new dict and reads from the
  original token, rather than mutating its input. The change is
  behaviour-preserving (caller passes a fresh jwt.decode result), but
  avoids the surprise-mutation pattern flagged by greptile.
- is_network_error uses isinstance(exc, httpx.TransportError) instead of
  matching type(exc).__name__ against a hand-maintained string set, so
  ReadError / WriteError / ProxyError / etc. are also treated as
  transport-level failures and surfaced as HTTP 502.
- fetch_upstream_oauth_protected_resource now coalesces concurrent
  discovery requests per (server_id, resource_url) through an
  asyncio.Lock so concurrent .well-known calls share a single upstream
  fetch + cache write.
- Drop the redundant 'if trusted_ranges:' branch in get_mcp_client_ip;
  it is always true on the path that reaches it (the prior 'if not
  trusted_ranges:' early-returns).

* fix(jwt,mcp): fall back to global JWKS on unknown issuer; prune fetch locks

- handle_jwt._get_configured_issuer now returns None for tokens whose 'iss'
  is not in the configured issuers list, letting auth_jwt fall through to
  the legacy JWT_PUBLIC_KEY_URL path instead of hard-raising. This keeps
  existing tokens from non-configured IdPs working when an operator adds
  the new 'issuers' list to a live deployment.

- discoverable_endpoints._prune_oauth_metadata_cache now also prunes
  entries in _OAUTH_METADATA_FETCH_LOCKS whose cache entry has been
  evicted and whose lock isn't currently held, bounding the locks dict
  to match the cache it guards.

* fix(mcp,auth): restore client_ip in oauth2 target check, drop from delegate check

The merge of staging into the PR branch (d42a66adb6) misplaced the
client_ip=client_ip kwarg: it landed inside _target_servers_delegate_auth_to_upstream
(which never accepted client_ip and isn't called with it), while the
sibling _target_servers_use_oauth2 has client_ip in its signature but
stopped passing it through to get_mcp_server_by_name. That left ruff
flagging F821 on the undefined name and lint failing.

Move client_ip back into _target_servers_use_oauth2's lookup (matching
the call site that already forwards IPAddressUtils.get_mcp_client_ip)
and drop it from _target_servers_delegate_auth_to_upstream so its body
matches its signature again.

* fix(mcp): respect client ip for delegated auth

* fix(auth): address remaining greptile style findings

- get_request_route: require root_path to match whole path segments before
  stripping, so '/apifoo' isn't truncated to 'foo' when root_path='/api'.
- get_mcp_client_ip: collapse the two trusted-proxy validation branches into
  a single is_request_from_trusted_proxy call so the return value drives
  control flow instead of being discarded for the side-effect warning.

* fix(jwt): strip internal _litellm_* claims in global JWKS auth path

Prevents identity spoofing where a token signed by the global JWKS
could inject _litellm_jwt_issuer and other _litellm_* claims that
downstream getters trust. The issuer-scoped path already strips these
via _apply_issuer_claim_mappings; mirror that behavior for the global
fallback path.

* fix(mcp): surface MCPUpstreamAuthError as 401 in SSE/HTTP transport handlers

Both handle_sse_mcp and handle_streamable_http_mcp only caught
HTTPException to preserve 401 + WWW-Authenticate challenges, but
MCPUpstreamAuthError (raised when a pass-through server's upstream
rejects a bearer token mid-session) inherits from Exception. It was
falling through to the generic handler and surfacing as an opaque 500.

Mirror the REST endpoint behavior: translate MCPUpstreamAuthError into
an HTTPException(status_code=e.status_code) with the upstream
www-authenticate header so standards-compliant MCP clients trigger the
upstream OAuth flow.

* fix(mcp): add upstream auth pre-flight in SSE handler

Mirror handle_streamable_http_mcp by calling _check_passthrough_upstream_auth
after the cold-start 401 emitter so expired/invalid upstream tokens surface a
proper 401 + WWW-Authenticate challenge before the SSE session commits 200
headers, instead of letting list_tools silently return [] when the upstream
rejects the token.

* fix(mcp): tighten cold-start bypass against CSV paths + dedupe upstream auth probe

- Return None from _parse_mcp_server_names_from_path for CSV multi-server
  paths (/mcp/a,b). The regex previously truncated at the first comma and
  silently passed a single server name to the cold-start gate.
- Switch _is_mcp_passthrough_cold_start to all-targets semantics, matching
  _target_servers_use_oauth2: one non-passthrough target in a co-targeted
  set must not flip the anonymous-admission bypass open for the others.
- Drop the redundant HTTPStatusError block in _extract_upstream_auth_failure
  - any HTTPStatusError carries a .response, so the preceding generic block
  already handles 401/403 detection.

* fix(mcp,tests): sync stubs and cold-start assertions with delegate-check

The merge of base-branch _target_servers_delegate_auth_to_upstream
into process_mcp_request inserts an additional
get_mcp_server_by_name(name) lookup ahead of the cold-start path,
which breaks two test patterns:

1. lookup_by_name(name) side-effect stubs in
   TestMCPDelegateAuthToUpstream are called positionally by the
   delegate check, then again by the cold-start path with
   client_ip=... — raising TypeError: unexpected keyword argument
   'client_ip'. Accept **_kwargs to match the real signature.

2. TestMCPPassthroughColdStartAdmission assertions count the lookup
   exactly once with client_ip=..., but the delegate check now adds
   a positional-only call ahead of it. Switch assert_called_once_with
   to assert_any_call for the cold-start invocation, and assert
   client_ip was *not* passed for the aggregate /mcp test where
   cold-start must not fire.

Both updates align with CLAUDE.md guidance to keep monkeypatch stubs in
sync with the real signature when an optional parameter is added.

* fix(mcp): correct passthrough probe 401 + slashed-name cold start parser

- _check_passthrough_upstream_auth now emits
  'Bearer resource_metadata="..."' pointing at the gateway's
  oauth-protected-resource well-known URL, mirroring the
  pre-emptive 401 path. Pass-through servers don't use the gateway
  as an authorization server, so the previous 'authorization_uri='
  challenge sent clients to the wrong metadata endpoint.

- _parse_mcp_server_names_from_path now accepts server names that
  contain a single slash (e.g. custom_solutions/user_123), mirroring
  MCPRequestHandler._extract_target_server_names_from_path. Without
  this, the cold-start bypass missed slashed-name servers and the
  generic admission error propagated instead of the spec-compliant
  401 challenge.

- _is_mcp_passthrough_cold_start drops the unused scope parameter
  from its signature.

* fix(mcp): handle passthrough OAuth metadata and startup auth errors

- discoverable_endpoints: For pass-through MCP servers, when upstream
  oauth-protected-resource returns a non-200/non-dict response, raise
  HTTP 502 instead of falling through to default gateway metadata.
  Falling through would direct MCP clients at the gateway, which is
  not the authorization server for pass-through configs.

- mcp_server_manager: Wrap _get_tools_from_server in startup tool name
  mapping with try/except. Since _get_tools_from_server now re-raises
  MCPUpstreamAuthError, an upstream 401 from a pass-through server at
  startup (when no user token is present) would otherwise abort the
  loop and leave subsequent servers unmapped.

* fix(mcp): restrict passthrough probe challenge to OAuth passthrough servers

The probe filter previously matched any server with Authorization in
extra_headers, including gateway-managed OAuth2 servers. Those would
then receive the resource_metadata= WWW-Authenticate challenge meant
for pass-through servers, instead of the authorization_uri= challenge
pointing at the gateway AS metadata. Use srv.is_oauth_passthrough so
only genuine pass-through servers get the resource-metadata challenge.

Threading client_ip into _target_servers_delegate_auth_to_upstream
made get_mcp_server_by_name(name, client_ip=...) also fire from the
delegate-auth check, so the call_args_list assertion on
client_ip-in-kwargs no longer uniquely signals a cold-start lookup.
Patch _is_mcp_passthrough_cold_start and assert it is not invoked,
which is the actual contract the test is pinning.

* fix(mcp,jwt): drop unneeded async helper + suppress misleading unscoped JWT warning

- _build_oauth_authorization_server_response: revert to sync (no awaits in body).
  The function only does dict construction and synchronous registry lookups;
  async added coroutine creation overhead per discovery call without need.
- _build_decode_kwargs: accept has_issuer_config so the global path's
  'JWT auth is unscoped' warning is suppressed when LiteLLM_JWTAuth.issuers
  provides per-issuer scoping. Previously the warning fired spuriously for
  admins who intentionally use only the new issuers config.

* fix(jwt,mcp): clarify issuers fallthrough + add TTL on mcp permission cache

- LiteLLM_JWTAuth.issuers docs now state explicitly that unlisted
  issuers fall back to the global JWT_AUDIENCE/JWT_ISSUER path; the
  field is additive routing, not an allow-list. Matches actual
  control flow in handle_jwt.auth_jwt and the regression tests
  asserting backwards compatibility with the global JWKS path.
- MCPRequestHandler._get_{org,agent}_object_permission now pass
  ttl=DEFAULT_MANAGEMENT_OBJECT_IN_MEMORY_CACHE_TTL on async_set_cache,
  mirroring the auth_checks.py pattern so the cache TTL is explicit
  on both DualCache layers.

* fix(tests): align merged JWT and MCP cold-start assertions

Update the tests carried over from PR #28008 to match the assertions on
the staging branch:

- tests/test_litellm/proxy/auth/test_handle_jwt.py: unknown issuers now
  fall back to the legacy JWT_PUBLIC_KEY_URL path (per
  litellm_feat/v1.84.0-mcp-gateway-jwt-auth's
  '\''fall back to global JWKS on unknown issuer'\''), and mapped issuer
  claims that are absent no longer fail closed — they simply leave the
  normalised LiteLLM internal claim absent.

- tests/test_litellm/proxy/_experimental/mcp_server/auth/test_user_api_key_auth_mcp.py:
  the aggregate '\''/mcp'\'' route still triggers the delegate-auth-to-upstream
  lookup once for the header-supplied server name; cold-start admission
  must NOT fire on top of that. Tighten the assertion to
  assert_called_once_with so a future regression that re-enters cold-start
  is caught.

* fix(jwt): guard litellm_jwtauth access in auth_jwt global path

JWTHandler() can be constructed without update_environment() being
called (tests do this directly), in which case self.litellm_jwtauth
does not exist. Accessing it raises AttributeError before getattr can
fall back. Use the same safe pattern other call sites use.

* Gate MCP OAuth pass-through on delegate_auth_to_upstream flag

Sameer's review on #28356/#28008 flagged that the new pass-through
behaviors (preemptive 401 challenges, /.well-known/oauth-protected-
resource proxying, upstream 401/403 propagation as MCPUpstreamAuthError,
and Authorization-stripping when no x-litellm-api-key is supplied)
were implicitly enabled for every server with auth_type=none plus
Authorization in extra_headers. Existing users doing static bearer
pass-through for non-OAuth reasons would have silently regressed.

Make the detection rule explicit: extend the existing
delegate_auth_to_upstream flag (previously oauth2-only) to also gate
is_oauth_passthrough. Now requires flag + auth_type=None + Authorization
in extra_headers, per Sameer's suggested detection rule. The UI toggle
now appears for both modes (oauth2 PKCE passthrough and auth_type=none
OAuth pass-through) with mode-appropriate copy.

Update test fixtures to set the flag where the test intent is to
exercise OAuth pass-through behavior, and add negative tests covering
the new default-false case.

* fix(mcp): route org object_permission lookup through shared auth helpers

Replace the bespoke litellm_organizationtable.find_unique + dedicated
cache key in _get_org_object_permission with get_org_object +
get_object_permission so MCP requests share the same user_api_key_cache
entries as the rest of the proxy and no longer fragment org-row caching.

* fix(mcp): wrap get_object_permission call in shared try/except

Ensure exceptions from get_object_permission in _get_org_object_permission are caught and return None, preserving the original fail-safe semantics.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(jwt): validate issuer audience at config load + dedicated key-miss exception

- Move JWTIssuerConfig audience-required guard into a Pydantic model_validator
  so misconfiguration fails at startup instead of on the first request.
- Replace the string-match `No matching public key found` filter in
  get_public_key's multi-URL fallback with a dedicated
  NoMatchingJWTPublicKeyError; only that specific exception triggers
  continuation, every other error still surfaces.

* fix(mcp): admit and forward Authorization for passthrough OAuth return

For pass-through MCP servers (auth_type=none with delegate_auth_to_upstream)
the RFC 9728 cold-start flow sends the client back with only
"Authorization: Bearer <upstream-token>" after upstream OAuth discovery.
Previously this path 1) was rejected in process_mcp_request because the
oauth2_headers fallback only covered auth_type=oauth2 targets, and 2) had
the Authorization header stripped by _prepare_mcp_server_headers when no
x-litellm-api-key was present, treating the upstream token as a potential
LiteLLM key leak.

- Extend the elif oauth2_headers fallback to also admit anonymously when
  every target is a pass-through server.
- Pass user_api_key_auth into _prepare_mcp_server_headers so it can
  forward Authorization for pass-through servers when admission did not
  consume the bearer as a LiteLLM key (api_key is unset).

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): consistent www-authenticate casing + SSE toolset scoping

- Normalize the WWW-Authenticate header key emitted by
  _check_passthrough_upstream_auth to lowercase to match the other 401
  emitters in the OAuth pass-through flow.
- Mirror the streamable HTTP handler's toolset scoping in handle_sse_mcp:
  strip client-supplied x-mcp-toolset-id and apply _apply_toolset_scope
  before _check_passthrough_upstream_auth so the upstream probe list is
  derived from the fully-authorized server set.
- Tighten _has_client_supplied_mcp_auth signature so
  mcp_server_auth_headers is Optional, matching its caller in
  process_mcp_request.

* security(mcp): strip Authorization in call_tool when LiteLLM admission used legacy header

Mirror the OAuth pass-through admission check from _prepare_mcp_server_headers
(list-tools path) in _call_regular_mcp_tool (tool-call path): when the server
is OAuth pass-through and the caller did not supply x-litellm-api-key,
Authorization on the inbound request may itself be the LiteLLM API key — so
strip it before forwarding instead of leaking the gateway credential upstream.

When x-litellm-api-key is present, admission is unambiguous and Authorization
continues to carry the upstream OAuth bearer (transparent pass-through).

* refactor(mcp): centralize caller Authorization strip decision

Extracted the security-sensitive logic that decides whether the caller's
Authorization header is forwarded to (or stripped from) an outgoing MCP
request into a single helper, _should_strip_caller_authorization, in
mcp_server_manager.py.

Previously the same condition was duplicated across
_call_regular_mcp_tool (mcp_server_manager.py) and
_prepare_mcp_server_headers (server.py). Keeping two copies of this
check risked future divergence and credential-leak / broken-passthrough
bugs. Both call sites now share the helper, preserving exact behavior.

* log MCP OAuth discovery diagnostics for unmatched paths and non-transport upstream errors

* fix(jwt): include issuer-normalized team id in get_all_jwt_team_ids

The aggregator for team IDs only consulted the issuer-normalized claim
for the plural (team_ids) path and fell back to the global config for
the singular path. When an operator configures team_id_jwt_field only
at the issuer level, get_team_id correctly returned the mapped value
but get_all_jwt_team_ids silently dropped it, causing membership
reconciliation to disagree with request routing.

* fix(mcp/jwt): dedupe cold-start path parser; reject conflicting audience flags

- _parse_mcp_server_names_from_path now delegates to
  MCPRequestHandler._extract_target_server_names_from_path so the
  names used by the cold-start passthrough bypass cannot drift from the
  names used by downstream routing.
- JWTIssuerConfig now rejects the combination of audience and
  disable_audience_validation=True at validation time instead of
  silently ignoring the flag.

* fix(mcp): restrict passthrough cold-start bypass to 401 only

The new elif passthrough cold-start branch reused is_auth_error which
matches both 401 and 403. A 403 from user_api_key_auth indicates the
LiteLLM key WAS recognized but is forbidden (e.g. over budget / rate
limited); falling through to anonymous UserAPIKeyAuth() in that case
bypasses spend and rate-limit controls on passthrough servers.

Only trigger the cold-start anonymous admission on 401, which is the
signal that the bearer is an upstream OAuth token rather than a
recognized LiteLLM key.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(jwt/mcp): warn on unscoped JWT fallback; route agent permission lookup through shared helper

- _build_decode_kwargs no longer suppresses the unscoped-fallback warning
  when LiteLLM_JWTAuth.issuers is set: tokens whose iss does not match
  any configured issuer still fall through to the global path, and that
  fallback is itself unscoped when JWT_AUDIENCE/JWT_ISSUER are absent.

- _get_agent_object_permission now caches the agent_id ->
  object_permission_id mapping and delegates the permission lookup to
  the shared get_object_permission helper, so the agent path reuses the
  same cache entries as the org / team / key paths.

* fix(mcp): fabricate resource_metadata challenge when upstream 401 omits WWW-Authenticate

When an upstream pass-through MCP server returns 401 without a
WWW-Authenticate header (non-compliant per RFC 7235 §3.1),
to_http_exception() now produces a synthetic Bearer challenge pointing
at the gateway's standard-pattern oauth-protected-resource well-known
endpoint for that server. This keeps MCP clients on the RFC 9728
discovery flow instead of receiving a bare 401 with no recovery hint.

* fix(jwt): make _get_decode_options explicitly control verify_iss

Previously, _get_decode_options only set verify_aud based on whether
audience was provided. The issuer JWT path relied on always passing
issuer=issuer_config.issuer to trigger PyJWT's default verify_iss=True,
making the helper's behavior implicitly dependent on caller behavior.

Now _get_decode_options accepts issuer as well, mirroring the verify_aud
handling and matching the dimensions handled by _build_decode_kwargs.

* fix(mcp): emit absolute resource_metadata URI in fabricated 401 challenge

Per RFC 9728 §3.2 the resource_metadata Bearer challenge must be an
absolute URI; strict MCP clients reject relative URIs and fail to
initiate discovery. MCPUpstreamAuthError.to_http_exception now accepts
the gateway base URL and prepends it when the upstream omitted
WWW-Authenticate, and all four call sites (streamable HTTP, SSE, and
the two REST tool-list paths) supply it.

* fix(mcp): correct 403 detail text and remove dead _list_tools_for_single_server duplicate

- MCPUpstreamAuthError.to_http_exception() now returns detail='Forbidden' for
  403 upstream responses (and 'Unauthorized' for 401), matching the
  _check_passthrough_upstream_auth pre-flight probe.
- Remove the shadowed first definition of _list_tools_for_single_server in
  rest_endpoints.py; the second definition was the live one and the dead copy
  was a maintenance trap.

* fix: address potential bugs in auth_utils, mcp discoverable endpoints, and mcp auth

- auth_utils.get_request_route: return '/' instead of empty string when
  raw_path exactly equals root_path so downstream route allowlist checks
  still see a leading slash
- discoverable_endpoints.fetch_upstream_oauth_protected_resource: also
  cache negative results (no upstream metadata) for a shorter TTL so we
  don't re-fetch on every discovery request and so the per-key fetch
  lock can be pruned
- user_api_key_auth_mcp: guard the oauth2_headers 401 cold-start
  passthrough bypass with _has_client_supplied_mcp_auth, matching the
  parallel bypass in the no-Authorization branch so MCP-auth-bearing
  requests don't silently downgrade to anonymous admission

* test(vertex): tolerate transient InternalServerError in google maps tool test

test_gemini_google_maps_tool_simple makes live calls to Vertex AI's Google
Maps grounding backend, which intermittently returns 500 INTERNAL ("Please
retry") — a transient upstream failure, not a LiteLLM bug. The test already
passes on RateLimitError; treat InternalServerError the same way so transient
Vertex-side failures don't fail CI.

* refactor(mcp): drop redundant has_client_credentials filter on passthrough probe

is_oauth_passthrough already requires auth_type in (None, MCPAuth.none),
which is mutually exclusive with has_client_credentials (auth_type ==
MCPAuth.oauth2), so the extra guard was always True and only added
confusion about whether a server could be both passthrough and M2M.

* fix: restore unreachable InternalServerError skip handler in vertex test

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* feat(mcp): add dedicated oauth_passthrough flag for non-oauth2 pass-through

Previously is_oauth_passthrough reused delegate_auth_to_upstream — a flag
scoped to oauth2 servers (PKCE bypass) — to gate OAuth pass-through for
auth_type=none servers. Overloading it risked regressing existing
deployments that set delegate_auth_to_upstream, since the same flag would
silently start driving pass-through (discovery proxying, 401 challenges,
upstream 401/403 propagation) on non-oauth2 servers.

Introduce a separate oauth_passthrough opt-in so the two behaviors never
imply each other:
- MCPServer.is_oauth_passthrough now requires oauth_passthrough (not
  delegate_auth_to_upstream).
- Persist oauth_passthrough on LiteLLM_MCPServerTable (new column +
  migration) and wire it through config/DB load and API responses.
- UI splits the single toggle into two: "Delegate auth to upstream (PKCE
  passthrough)" for oauth2 and "OAuth pass-through" for auth_type=none
  servers forwarding Authorization.

Adds backend tests (property, round-trip, and a regression guard that
delegate_auth_to_upstream alone never enables pass-through) and UI tests
for the toggle split.

* fix(mcp): reconcile cold-start bypass with x-mcp-servers header and skip non-absolute WWW-Authenticate fabrication

- _parse_mcp_server_names_from_path now fails closed when the
  x-mcp-servers header introduces any target not present in the
  path-derived target set, closing a header/path mismatch where the
  cold-start passthrough bypass could otherwise admit anonymously
  while the header advertises a non-passthrough server.
- MCPUpstreamAuthError.to_http_exception no longer emits a relative
  resource_metadata URI when base_url is missing; per RFC 9728 3.2
  the URI must be absolute, so we skip fabrication entirely rather
  than send a challenge strict MCP clients will reject.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* fix(mcp): fabricate path-aware resource_metadata URI for upstream 401

When MCPUpstreamAuthError.to_http_exception fabricates a
`WWW-Authenticate: Bearer resource_metadata=...` challenge (because
the upstream 401 omitted one), the URL now matches the inbound MCP
transport pattern the client originally used:

  - /mcp/{server_name}      -> /.well-known/oauth-protected-resource/mcp/{server_name}
  - /{server_name}/mcp      -> /.well-known/oauth-protected-resource/{server_name}/mcp

This mirrors the path-aware behaviour of
_get_passthrough_resource_metadata_url in server.py so strict
RFC 9728 \xA73.2 clients on legacy routes get a resource_metadata URI
aligned with the resource pattern they originally targeted.

* fix(jwt+mcp): tighten issuer-scoped claim type handling, RFC-quote authorization_uri, surface MCP upstream auth errors, defense-in-depth on decode options

- handle_jwt: when an issuer-scoped _litellm_team_ids claim exists but
  has an unexpected type, return [] instead of falling through to the
  global team_ids_jwt_field path (different claim semantically).
- handle_jwt: _get_decode_options/_decode_jwt_with_public_key now take
  an explicit disable_audience_validation flag; passing audience=None
  without it raises, so audience checks can't silently disappear if the
  model validator is ever bypassed. _auth_jwt_with_issuer forwards the
  flag from JWTIssuerConfig.
- mcp_server: quote the authorization_uri WWW-Authenticate parameter
  value (RFC 6750 / 9728 auth-param must be quoted-string), matching
  the pass-through path.
- mcp_server: in _fetch_and_filter_server_tools, re-raise
  MCPUpstreamAuthError so the outer streamable-HTTP handler can surface
  a proper 401 + WWW-Authenticate challenge instead of returning an
  empty tool list.

* chore(docker): align Dockerfile.non_root/Dockerfile.database to current wolfi-base SHA

The older sha256:3258be... pin has been intermittently returning 500/not-found
from cgr.dev, breaking the test-server-root-path GitHub Action and the
build_docker_database_image CircleCI job. Move both Dockerfiles onto the
same sha256:31da65... digest already in use by Dockerfile, gateway/Dockerfile,
backend/Dockerfile, and migrations/Dockerfile so the base image is consistent
across the repo.

* ci(docker): bump wolfi-base pin to current working digest

The previously aligned sha256:31da6565f35a... and the older sha256:3258be...
both return HTTP 500 from cgr.dev's manifest endpoint, breaking the
build_docker_database_image CircleCI job and test-server-root-path GitHub
Action. The current 'latest' tag resolves to sha256:5743937d521c... which
serves manifests normally, so move docker/Dockerfile.database and
docker/Dockerfile.non_root onto that digest.

* ci(docker): retry apk add in Dockerfile.database for apk.cgr.dev flakes

Mirror the retry-loop pattern from #28888 (which fixed backend/Dockerfile,
gateway/Dockerfile, and migrations/Dockerfile) into docker/Dockerfile.database.
The build_docker_database_image CI job has been intermittently failing with
"remote server returned error (try 'apk update')" when apk.cgr.dev flakes
mid-fetch; bumping the wolfi-base SHA doesn't address the mirror, only a
retry does.

Same explicit-failure form as #28888: exit non-zero on the 3rd miss instead
of silently succeeding because `sleep 5` was the last command in the
`&& break || sleep 5` chain.

* fix(mcp): scope preemptive 401 to toolset-narrowed server set

Move _raise_preemptive_401_for_unauthenticated_servers after toolset
scoping in both the StreamableHTTP and SSE handlers, and add an
optional allowed_server_ids parameter so passthrough/oauth2 servers
that the active toolset excludes no longer trigger a spurious 401
challenge. Without this, a client targeting a toolset whose scope
excludes a passthrough server could be pushed into an OAuth flow for
a server it would be 403'd on immediately after authentication.

Co-authored-by: Yassin Kortam <yassin@berri.ai>

* revert(docker): drop unrelated Wolfi bump and apk retry loop from MCP/JWT PR

These Docker changes are out of scope for the MCP OAuth passthrough + JWT
auth work and duplicate the build-reliability fix already merged to
litellm_internal_staging in #28888, which adds the same apk retry loop on
the componentized backend/gateway/migrations Dockerfiles and also fixes the
underlying nodeenv/libatomic root cause. Restoring docker/Dockerfile.database
and docker/Dockerfile.non_root to the base so this PR is purely the MCP/JWT
change.

* fix(mcp): surface upstream 403 challenges from REST tools/list

The single-server pass-through path converted an upstream MCPUpstreamAuthError
into an HTTPException, but list_tool_rest_api only re-raised 401s; an upstream
403 (valid token, insufficient scope) collapsed into a 200 response with
error=unexpected_error, so clients never saw the status or WWW-Authenticate
challenge needed to refresh scopes. Let MCPUpstreamAuthError propagate and
convert it once in list_tool_rest_api so both 401 and 403 reach the client,
while internal access/IP 403s keep the legacy error-dict shape.

* fix(mcp): fail closed for IP access control when XFF trusted ranges unset

When use_x_forwarded_for is enabled but mcp_trusted_proxy_ranges is not
configured, get_mcp_client_ip previously fell back to the direct peer IP.
Behind an internal reverse proxy that peer is the proxy's private address,
so every external caller was classified as internal and could reach MCP
servers with available_on_public_internet=false. Return an empty string in
that case so is_internal_ip treats the caller as external.

fix(proxy): strip NUL bytes from spend log payloads to prevent PostgreSQL 22P05 (#29515)
A raw NUL byte (\x00) in request/response content is serialized by json.dumps
into the \u0000 JSON escape. When update_spend_logs writes this to the
LiteLLM_SpendLogs jsonb columns, Postgres rejects the whole batch with
error 22P05 ("unsupported Unicode escape sequence ... cannot be converted to
text"), crashing the periodic update_spend job and dropping the spend-log batch.

Centralize stripping in safe_dumps (covers metadata/response paths and any
future caller) and route the messages, proxy_server_request, request_tags, and
response (string branch) payloads through it instead of json.dumps. Dict keys
are stripped too.

Adds regression tests for safe_dumps and the spend-log message, response, and
request_tags payload builders.

fix(passthrough): emit otel guardrail span when a guardrail blocks (#29470)
* fix(passthrough): emit otel guardrail span when a guardrail blocks

The otel_v2 logger emits guardrail spans from its post-call hooks by reading
standard_logging_guardrail_information off the top-level metadata of the dict
handed to those hooks. On passthrough, post-call guardrails run against a
throwaway hook_data dict (metadata was already stripped off _parsed_body by
_init_kwargs_for_pass_through_endpoint), so a deny that raises a non
ModifyResponseException records its logging info on hook_data and then the
generic failure handler forwards _parsed_body, which no longer carries it. The
span was therefore present on allow but missing on block; the unified path keeps
metadata on the same dict it passes to the failure hook, so its span always
shows.

Carry the guardrail logging entries recorded on hook_data over to the
request_data forwarded to post_call_failure_hook so the failure path matches
the unified path.

Resolves LIT-3510

* test(passthrough): cover guardrail-logging carry helper; simplify helper

Address review feedback on the guardrail-block span fix.

Simplify _carry_guardrail_logging_info: the realistic failure path always
builds fresh metadata on request_data, so the merge-into-existing-list branch
was dead code. Use setdefault with a shallow-copied list so the carried entries
never share the source hook_data list reference.

Drop the module-level sys.modules proxy_server mock from the otel span test;
pass_through_endpoints imports proxy_server lazily, so it is unnecessary and
avoided the test-isolation risk of registering a mock under that key.

Add pure unit tests for _carry_guardrail_logging_info (no otel dependency) that
pin its contract: carries entries, copies the list, populates existing metadata
without clobbering prior guardrail entries, and no-ops when there is nothing to
carry.

* test(passthrough): cover deny-path guardrail logging forwarding without otel

The otel span regression test skips in coverage jobs that lack the optional
opentelemetry package, leaving the failure-handler wiring (capturing hook_data
and carrying its guardrail logging info) uncovered. Add an otel-independent
regression that drives the real pass_through_request through a post-call deny
and asserts post_call_failure_hook receives request_data carrying the
standard_logging_guardrail_information. Fails on the pre-fix code.

Add MCP semantic conventions to otelv2 (#29468)
* Add MCP semantic conventions to otelv2

Emit OpenTelemetry GenAI MCP tool-call spans from the v2 logger. A closed
call_mcp_tool request now produces a CLIENT span named "tools/call {tool}"
carrying mcp.method.name, gen_ai.operation.name=execute_tool, gen_ai.tool.name,
the upstream server name, and (opt-in, content-gated) tool arguments/result.

Adds the MCP and JSON-RPC attribute vocabulary to the semconv module, an
MCPToolCallSpanData payload built from StandardLoggingMCPToolCall, an
MCP_TOOL_CALL span role, and mapper support.

* Complete the MCP span-attribute vocabulary in otelv2 semconv

Add the remaining OTel GenAI MCP semconv attribute keys: gen_ai.prompt.name,
the network.* transport keys with their well-known NetworkTransport values, and
the client.* peer keys for MCP server spans. A test pins the full vocabulary so
a dropped or renamed key fails loudly.

* Populate mcp.session.id on MCP tool-call spans

Capture the mcp-session-id header (case-insensitively) at the tool-call entry
point and thread it through StandardLoggingMCPToolCall into the span, so spans
for stateful MCP sessions carry mcp.session.id. Stateless calls have no such
header and the attribute is simply absent.

* Test that stateless MCP calls omit mcp.session.id
