- Skip ``kwargs["tools"] = []`` injection when compression is a no-op —
Anthropic Messages rejects empty tool arrays on requests that did not
originally declare tools.
- Move agentic-loop safety guards (fingerprint cycle / max depth) out of
the per-callback try/except so they propagate instead of being swallowed
by the generic exception handler. Extracted _check_agentic_loop_safety.
- Gate generic ``x-<vendor>-session-id`` capture behind the
LITELLM_CAPTURE_VENDOR_SESSION_HEADERS env var (off by default) to
preserve backwards compatibility; explicit x-litellm-* headers are
unaffected.
- Fix monkeypatch target in pre-call-hook test to patch the actual
module-level binding
(litellm.integrations.compression_interception.handler.compress).
- Add regression tests for empty-tools skip and opt-in session capture.

* revert: drop LITELLM_CAPTURE_VENDOR_SESSION_HEADERS flag
Generic x-<vendor>-session-id header capture is a new feature and only
runs *after* the explicit x-litellm-trace-id / x-litellm-session-id
checks, so it does not change behavior for any existing caller that was
already using the LiteLLM headers — no backwards-incompatibility to gate.

* refactor(compress): replace input_type with CallTypes call_type
Drop the bespoke ``CompressionInputType`` literal and use the existing
``litellm.types.utils.CallTypes`` enum instead. ``litellm.compress()``
now takes ``call_type: Union[CallTypes, str]`` (default
``CallTypes.completion``) — no new concept to learn, and the enum is
already the way the rest of the codebase talks about request shapes.
Supported values: ``completion`` / ``acompletion`` (OpenAI chat-completions
shape) and ``anthropic_messages`` (Anthropic structured content blocks).
Updated: compress(), the compression_interception handler, tests, docs,
and the two eval scripts.

Router coverage check flagged this method as untested. Adds two cases:
- initializes AdaptiveRouter from model_list and is idempotent on re-entry
- no-op when no adaptive deployments are configured

Fixes#26014
Made-with: Cursor
Per-user OAuth MCP requests now only skip pre-emptive 401 when a stored token is available, preserving token-reuse behavior while restoring fast PKCE kickoff for first-time or missing-token users.
Addresses Greptile P1: `metadata: null` on a key with a reserved field
was crashing inside prepare_metadata_fields because cast(dict, None) is
a runtime no-op, so the loop hit `reserved_field in None` and returned
500 instead of 400.
Extend the rejection condition to cover `casted_metadata is None`, so
attempts to clear an immutable field via `metadata: null` return 400
consistently with the overwrite path. Non-service-account keys still
fall through to the existing "clear all metadata" behavior.
Addresses Greptile review feedback:
- Clarify LiteLLM_Reserved_Metadata_Fields comment to describe both
preserve-on-omit and reject-on-change behaviors.
- Treat explicit null as a change attempt so callers trying to clear
service_account_id get a 400 instead of a silent no-op.
`should_create_missing_views()` had `and result[0]["reltuples"]` which is
falsy when reltuples=0. On a fresh empty PostgreSQL table, CREATE INDEX sets
reltuples=0, causing the guard to return False and skip view creation entirely.
Views like MonthlyGlobalSpendPerKey are never created, and the
/global/spend/logs endpoint returns 500.
Fix: change to `and result[0]["reltuples"] is not None` so reltuples=0
(empty table) and reltuples=-1 (unanalyzed table) both correctly return True.
Also harden test_vertex_ai.py to return None instead of crashing with
JSONDecodeError when the spend-logs endpoint returns a non-JSON 500 response,
and add unit tests covering all three reltuples branches (0, -1, positive).
test_virtual_key_max_budget_alert_check_per_key_overrides_global asserted
override semantics but the implementation does additive merge. Renamed test
and updated assertion to match: per-key and global thresholds are unioned,
not replaced.
/key/update and /user/update wholesale-replaced the metadata JSON column
whenever a caller passed a `metadata` field, silently dropping
service_account_id. The pre-call check in litellm_pre_call_utils.py then
stopped treating the key as a service account and bypassed
service_account_settings.enforced_params.
Add LiteLLM_Reserved_Metadata_Fields and have prepare_metadata_fields
preserve these keys from the existing row when the caller omits them.
Reject attempts to change an already-set value (400) since rebinding
service_account_id would break spend attribution.
Fixes SyntaxError at pytest collection time caused by leftover
<<<<<<<, =======, >>>>>>> markers in test_bedrock_common_utils.py.
Keeps the assertion matching the model under test
(claude-haiku-4-5-20251001-v1:0).
Project-level model rpm/tpm limits stored in project_metadata were never
checked during rate limit enforcement — only model-level limits applied.
Adds _add_project_model_rate_limit_descriptor_from_metadata() to the v3
limiter (mirrors the existing team metadata path) and calls it in
async_pre_call_hook, creating a model_per_project descriptor keyed as
"{project_id}:{model}" with the project's configured limits.
Also extends get_model_rate_limit_from_metadata's Literal to accept
"project_metadata" and adds get_project_model_rpm/tpm_limit helpers.

- Guard empty recipients in _handle_multi_threshold_max_budget_alert:
log warning and skip instead of falling through to old path error loop
- Widen max_budget_alert_emails type to Dict[str, Union[str, List[str]]]
to match _parse_email_list runtime behavior (accepts comma-separated strings)
- Pre-filter asyncio.create_task with min threshold check to avoid
unnecessary task allocation on every request when spend is below
all configured thresholds
When litellm.max_end_user_budget_id is configured, implicitly-created end users
(via /chat/completions) have budget_id=NULL in the DB since the default budget
is only applied in-memory. The budget reset job filtered by budget_id, so these
users were never reset and eventually permanently blocked.
Fix: when the default budget is in the reset list, also query for and reset
end users with budget_id=NULL and spend > 0. This keeps the hot auth path
unchanged (no DB writes on every request).
Fixes#22019

- Add `default_key_max_budget_alert_emails` litellm_settings config as
global fallback for all virtual keys (per-key metadata takes priority)
- Fix crash when key has no user_id/user_email by passing recipient email
to _get_email_params (same pattern as team soft budget path)
- Use owner email for greeting, falling back to key_alias or token
- Rename setting from default_max_budget_alert_emails to
default_key_max_budget_alert_emails for clarity
Previously, _apply_default_budget_to_end_user() only set the budget in-memory,
leaving budget_id NULL in the database. This caused the budget reset job to skip
these users since it filters by budget_id. Now the function also persists
budget_id via a Prisma update call (non-fatal on failure).
Fixes#22019

Users can set metadata.max_budget_alert_emails as a JSON map of threshold
percentages to email recipients on virtual keys. When configured, the email
handler loops over each threshold, checks per-threshold dedup cache, and
sends to the configured recipients (auto-including the key owner's email).
When no map is set, the existing single 80% threshold behavior is preserved
unchanged. Teams support is out of scope for this v0.

- url_utils.py: narrow sockaddr[0] from str|int to str via a helper with a
fail-closed isinstance check. Fixes the two mypy errors introduced by
the SSRF hardening without masking unexpected stdlib behavior.
- key_management_endpoints.py: restore the documented team member_permissions
path for /key/update. The cross-key admin check added to close the
cross-org rewrite attack was over-broad: it rejected non-admin team
members even when can_team_member_execute_key_management_endpoint had
already validated their team membership and /key/update grant. Now skip
the admin check when the key has a team_id and the change is non-budget
(membership + permission already enforced above). Budget/spend changes
still require team/org admin. The cross-org attack remains blocked:
an outside org admin fails the earlier team membership check.
- test_logging_redaction_e2e_test.py: rename and rewrite two parametrized
tests to assert that request-body turn_off_message_logging has no effect.
Reflects the intentional removal of turn_off_message_logging from
_supported_callback_params so the caller cannot override admin logging
policy via the request body.
- test_key_management_endpoints.py: add two tests covering the restored
team member permission path — one positive (non-budget update succeeds
for a team member with /key/update grant), one negative (max_budget
change still rejected without admin role).
