fix(mcp): forward staged credentials on /mcp-rest/test/connection like /test/tools/list The connection preview built its temporary MCP client without the credentials the not-yet-saved server config carries: the Authorization bearer an OAuth2 authorization_code server had just been granted, the auth_value of an api_key, bearer_token, basic, or authorization server, and the stored credentials of a saved server being edited. The tools preview forwarded all three, so the same request succeeded there and failed on the connection test with the generic "Failed to connect to MCP server" message Both previews now resolve those credentials through one shared staging step, so they cannot drift apart again, and the Authorization header is only forwarded upstream when the primary x-litellm-api-key header carried admission, since otherwise it is the caller's LiteLLM key --- .../mcp_server/rest_endpoints.py | 85 ++++++----- .../mcp_server/test_rest_endpoints.py | 134 ++++++++++++++++++ 2 files changed, 186 insertions(+),

Every outbound WebSocket dial killed its tokio worker and the client saw the socket vanish with no close frame. reqwest and the AWS SDK both pick a provider explicitly, so only the tungstenite path was affected.

Adds an integration test, which gets its own process, that dials wss:// at a local plain-TCP listener through the public Responses WebSocket entrypoint and asserts an Err plus an installed provider. Without the install in the dial it panics with the original CryptoProvider message. A unit test now compares the installed provider's cipher suites and key-exchange groups against ring's, so the choice of backend is pinned rather than assumed. Also names tls12 in the workspace rustls features: it already arrives through reqwest and tokio-rustls, so the graph is unchanged, but a direct dependency should say it needs TLS 1.2 rather than inherit it. --- litellm-rust/Cargo.toml | 2 +- litellm-rust/crates/ai-gateway/src/io/tls.rs | 43 +++++++++++++++++-- .../tests/crypto_provider_wiring.rs | 41 ++++++++++++++++++ 3 files changed, 81 insertions(+), 5 deletions(-) create mode 100644 litellm-rust/crates/ai-gateway/tests/crypto_provider_wiring.rs diff --git a/litellm-rust/Cargo.toml b/litellm-rust/Cargo.toml index 15074082981..2e2e8809b7f 100644 --- a/litellm-rust/Cargo.toml +++ b/litellm-rust/Cargo.toml @@ -26,7 +26,7 @@ pythonize = "0.29.0" rand = "0.8" reqwest = { version = "0.12", default-features = false, features = ["blocking", "json", "rustls-tls", "http2", "stream"] } rstest = "0.26.1" -rustls = { version = "0.23", default-features = false, features = ["ring", "std"] } +rustls = { version = "0.23", default-features = false, features = ["ring", "std", "tls12"] } serde = { version = "1.0", features = ["derive"] } serde_json = "1.0" sha2 = "0.10" diff --git a/litellm-rust/crates/ai-gateway/src/io/tls.rs b/litellm-rust/crates/ai-gateway/src/io/tls.rs index e3754e44002..96544adffb7 100644 --- a/litellm-rust/crates/ai-gateway/src/io/tls.rs +++ b/litellm-rust/crates/ai-gateway/src/io/tls.rs @@ -8,7 +8,7 @@ //!

17:29:10 -0700 Subject: [PATCH 021/123] fix(ai-gateway): dial upstream WebSockets over an explicit rustls provider Build one ClientConfig that names ring and loads the native roots once, and hand it to every tokio-tungstenite dial as its connector instead of installing a process-wide default from the dial path. Each of the three dial sites gets a wss:// test that reproduces the panic if its connector is dropped. --- litellm-rust/Cargo.lock | 1 + litellm-rust/Cargo.toml | 1 + litellm-rust/crates/ai-gateway/Cargo.toml | 5 +- .../crates/ai-gateway/src/io/realtime.rs | 27 +++++ .../crates/ai-gateway/src/io/responses_ws.rs | 23 ++++ litellm-rust/crates/ai-gateway/src/io/tls.rs | 113 ++++++++++-------- .../tests/crypto_provider_wiring.rs | 19 ++- 7 files changed, 134 insertions(+), 55 deletions(-) diff --git a/litellm-rust/Cargo.lock b/litellm-rust/Cargo.lock index 2ed998174e4..d214e80d818 100644 --- a/litellm-rust/Cargo.lock +++ b/litellm-rust/Cargo.lock @@ -1416,6 +1416,7 @@ dependencies = [ "pyo3", "reqwest", "rustls 0.23.42", + "rustls-native-certs", "serde", "serde_json", "sha2 0.10.9", diff --git a/litellm-rust/Cargo.toml b/litellm-rust/Cargo.toml index 2e2e8809b7f..d3d25cbda8d 100644 --- a/litellm-rust/Cargo.toml +++ b/litellm-rust/Cargo.toml @@ -27,6 +27,7 @@ rand = "0.8" reqwest = { version = "0.12", default-features = false, features = ["blocking", "json", "rustls-tls", "http2", "stream"] } rstest = "0.26.1" rustls = { version = "0.23", default-features = false, features = ["ring", "std", "tls12"] } +rustls-native-certs = "0.8" serde = { version = "1.0", features = ["derive"] } serde_json = "1.0" sha2 = "0.10" diff --git a/litellm-rust/crates/ai-gateway/Cargo.toml b/litellm-rust/crates/ai-gateway/Cargo.toml index 414abc2356d..82bedd0c8a0 100644 --- a/litellm-rust/crates/ai-gateway/Cargo.toml +++ b/litellm-rust/crates/ai-gateway/Cargo.toml @@ -19,9 +19,10 @@ litellm-core = { workspace = true, features = ["bedrock-auth"] } # reqwest (rustls + json) is used by io/ocr and ships realtime logs to the # Python proxy callbacks API. reqwest.workspace = true -# rustls is a direct dependency so `io::tls` can install a process-level -# crypto provider;

Gemini fetches off the event loop The SSRF check in async_safe_get resolved DNS on the event loop and a blocked address was retried three times; validate_url now runs in a thread and an SSRFError fails the fetch on the first attempt in both fetchers. The shared HTTP handler signed the request and ran pre_call logging on the loop after an async transform; both now run in a thread. Vertex AI Gemini still fetched http:// images and https images without an inferrable mime type with the sync converter inside its async body builder; the walker takes a should_inline predicate and Vertex AI inlines exactly those URLs, leaving https images with a known mime type and Files API refs to Google. When one download fails the other in-flight downloads for that request are now cancelled instead of finishing in the background --- .../prompt_templates/image_handling.py | 73 ++++++++-- litellm/litellm_core_utils/url_utils.py | 3 +- litellm/llms/custom_httpx/llm_http_handler.py | 2 +- .../llms/vertex_ai/gemini/transformation.py | 26 +++- .../litellm_core_utils/test_image_handling.py | 135 ++++++++++++++++-- .../litellm_core_utils/test_url_utils.py | 35 +++++ .../custom_httpx/test_llm_http_handler.py | 28 +++- .../vertex_ai/gemini/test_transformation.py | 51 +++++++ 8 files changed, 318 insertions(+), 35 deletions(-) diff --git a/litellm/litellm_core_utils/prompt_templates/image_handling.py b/litellm/litellm_core_utils/prompt_templates/image_handling.py index 55c01b3b1cb..dcad7776b58 100644 --- a/litellm/litellm_core_utils/prompt_templates/image_handling.py +++ b/litellm/litellm_core_utils/prompt_templates/image_handling.py @@ -4,7 +4,7 @@ Helper functions to handle images passed in messages import asyncio import base64 -from collections.abc import Mapping +from collections.abc import Callable, Mapping from dataclasses import dataclass from types import MappingProxyType from typing import Final @@ -15,7 +15,7 @@ import litellm from litellm import verbose_logger from litellm.caching.caching import InMemoryCache from litellm.constants import MAX_IMAGE_URL_DOWNLOAD_SIZE_MB -from litellm.litellm_core_utils.url_utils import async_safe_get, safe_get +from litellm.litellm_core_utils.url_utils import SSRFError, async_safe_get, safe_get from litellm.types.llms.openai import AllMessageValues MAX_IMGS_IN_MEMORY: Final = 10 @@ -99,6 +99,8 @@ async def async_convert_url_to_base64(url: str) -> str: return _process_image_response(response, url) except litellm.ImageFetchError: raise + except SSRFError as e: + raise litellm.ImageFetchError(f"Error: Unable to fetch image from URL. {e} url={url}") from e except Exception: pass raise litellm.ImageFetchError(f"Error: Unable to fetch image from URL after 3 attempts. url={url}") @@ -125,6 +127,8 @@ def convert_url_to_base64(url: str) -> str: return _process_image_response(response, url) except litellm.ImageFetchError: raise + except SSRFError as e: + raise litellm.ImageFetchError(f"Error: Unable to fetch image from URL. {e} url={url}") from e except Exception as e: verbose_logger.exception(e) raise litellm.ImageFetchError( @@ -163,9 +167,23 @@ _ANTHROPIC_MEDIA_BLOCK_TYPES: Final = frozenset({"document", "image"}) @dataclass(frozen=True, slots=True) class _RemoteSource: part: Mapping[str, object] + source: Mapping[str, object] url: str +@dataclass(frozen=True, slots=True) +class RemoteMedia: + url: str + fields: Mapping[str, object] + + +_NO_FIELDS: Final[Mapping[str, object]] = MappingProxyType({}) + + +def inline_every_remote_url(_media: RemoteMedia) -> bool: + return True + + def _parse_remote_image(fields: Mapping[str, object]) -> _RemoteImage | None: if fields.get("type") != "image_url": return None @@ -184,7 +202,7 @@ def _parse_remote_file(fields: Mapping[str, object]) -> _RemoteFile | None: def _parse_remote_source(fields: Mapping[str, object]) -> _RemoteSource | None: source: Final = _as_mapping(fields.get("source")) if fields.get("type") in _ANTHROPIC_MEDIA_BLOCK_TYPES else None url: Final = _remote_url(source.get("url")) if source is not None and source.get("type") == "url" else None -

0ee3bec046bf0f15eebdddc1d52610d389ca220f Mon Sep 17 00:00:00 2001 From: mateo-berri <277851410+mateo-berri@users.noreply.github.com> Date: Fri, 4 Sep 2026 23:20:21 -0700 Subject: [PATCH 034/123] fix(image_edit): await an async transform hook and hide the URL policy verdict from callers The image edit handler now awaits BaseImageEditConfig.async_transform_image_edit_request, and Black Forest Labs overrides it so URL images and masks download through async_safe_get instead of the blocking safe_get on the event loop. Rejected image fetches raise a fixed policy message with the user_url_allowed_hosts hint rather than echoing the resolver's verdict (resolved IP, DNS failure) back to the caller. The test fixture also fails any request-path call of the sync convert_url_to_base64 so a regression cannot pass unnoticed. --- .../prompt_templates/image_handling.py | 12 +- .../base_llm/image_edit/transformation.py | 19 ++ .../image_edit/transformation.py | 102 ++++++----- litellm/llms/custom_httpx/llm_http_handler.py | 2 +- tests/test_litellm/conftest.py | 10 +- .../litellm_core_utils/test_image_handling.py | 65 ++++--- .../test_bfl_image_edit_transformation.py | 78 ++++++++- .../custom_httpx/test_llm_http_handler.py | 163 +++++++++++++++++- 8 files changed, 379 insertions(+), 72 deletions(-) diff --git a/litellm/litellm_core_utils/prompt_templates/image_handling.py b/litellm/litellm_core_utils/prompt_templates/image_handling.py index dcad7776b58..4e7dfdb4017 100644 --- a/litellm/litellm_core_utils/prompt_templates/image_handling.py +++ b/litellm/litellm_core_utils/prompt_templates/image_handling.py @@ -78,6 +78,14 @@ def _process_image_response(response: Response, url: str) -> str: return result +def _url_policy_rejection(url: str, verdict: SSRFError) -> "litellm.ImageFetchError": + verbose_logger.warning("Image fetch of %s rejected by the URL policy: %s", url, verdict) + return litellm.ImageFetchError( + "Error: Unable to fetch image from URL.

035/123] fix(image_handling): tell callers when the image host did not resolve instead of blaming the URL policy validate_url raises HostResolutionError, a SSRFError subclass, for the two DNS outcomes (lookup failed, no addresses). The image fetch helper maps that to a "host could not be resolved" message and keeps the user_url_allowed_hosts hint for the policy verdicts it can actually fix. --- .../prompt_templates/image_handling.py | 14 +++-- litellm/litellm_core_utils/url_utils.py | 8 ++- .../litellm_core_utils/test_image_handling.py | 56 +++++++++++-------- .../litellm_core_utils/test_url_utils.py | 19 ++++++- 4 files changed, 64 insertions(+), 33 deletions(-) diff --git a/litellm/litellm_core_utils/prompt_templates/image_handling.py b/litellm/litellm_core_utils/prompt_templates/image_handling.py index 4e7dfdb4017..99efbd13320 100644 --- a/litellm/litellm_core_utils/prompt_templates/image_handling.py +++ b/litellm/litellm_core_utils/prompt_templates/image_handling.py @@ -15,7 +15,7 @@ import litellm from litellm import verbose_logger from litellm.caching.caching import InMemoryCache from litellm.constants import MAX_IMAGE_URL_DOWNLOAD_SIZE_MB -from litellm.litellm_core_utils.url_utils import SSRFError, async_safe_get, safe_get +from litellm.litellm_core_utils.url_utils import HostResolutionError, SSRFError, async_safe_get, safe_get from litellm.types.llms.openai import AllMessageValues MAX_IMGS_IN_MEMORY: Final = 10 @@ -78,8 +78,12 @@ def _process_image_response(response: Response, url: str) -> str: return result -def _url_policy_rejection(url: str, verdict: SSRFError) -> "litellm.ImageFetchError": - verbose_logger.warning("Image fetch of %s rejected by the URL policy: %s", url, verdict) +def _rejected_image_fetch(url: str, verdict: SSRFError) -> "litellm.ImageFetchError": + verbose_logger.warning("Image fetch of %s rejected before any request went out: %s", url, verdict) + if isinstance(verdict, HostResolutionError): + return litellm.ImageFetchError( + f"Error: Unable to fetch image from URL.

xargs list missed a ruff-tests.toml rule change and skipped ruff on deletions, so the block now runs test-linting.yml's exact command over tests/. ruff-tests.toml, test-quality-budget.json, and scripts/check_test_quality.py trigger the block too, and it sits after the background launches so the dashboard and gen:api jobs overlap it. --- scripts/pre_commit_lint.sh | 36 ++++----

A poll that landed while the batch was still validating or in progress wrote that row at $0 and no later retrieve could overwrite it, and every completed retrieve after the first added the cost to the key, team, and user counters again with no new row to show for it. The cost callback now writes nothing for a batch retrieve until the batch is final, releasing the poll's budget reservation instead, and once it is final it charges only when no spend row for that batch is queued for flush or already stored. Batch cost rows are flushed to the database right away so a second instance sees them, and the logger prices a batch only once it is final, which also covers a failed batch that never produced an output file. --- litellm/batches/batch_utils.py | 20 ++ litellm/litellm_core_utils/litellm_logging.py | 13 +- litellm/proxy/db/db_spend_update_writer.py | 3 +- .../proxy/hooks/proxy_track_cost_callback.py | 56 ++++- .../openai_files_endpoints/common_utils.py | 8 +- litellm/proxy/utils.py | 10 +- .../test_litellm/batches/test_batch_utils.py | 55 +++- .../test_litellm_logging.py | 82 ++++++ .../proxy/db/test_db_spend_update_writer.py | 10 +- .../hooks/test_proxy_track_cost_callback.py | 238 +++++++++++++----- .../prisma_and_spend/test_spend_functions.py | 15 ++ 11 files changed, 428 insertions(+), 82 deletions(-) diff --git a/litellm/batches/batch_utils.py b/litellm/batches/batch_utils.py index 97be5f77d79..eaac3bf0e9f 100644 --- a/litellm/batches/batch_utils.py +++ b/litellm/batches/batch_utils.py @@ -25,6 +25,26 @@ class BatchCostUsageResult: failed_requests: int +_TERMINAL_BATCH_STATUSES: Final = frozenset({"completed", "failed", "cancelled", "expired"}) + + +def batch_cost_is_final(batch: Batch) -> bool: + """Whether this retrieve of the batch is the one to account its cost from. + + A batch still in flight has nothing to price, and a "completed" batch can report + no output_file_id for a moment before the output populates; pricing either records + $0 under the batch's single spend row and pins it there.

The spend update writer now inserts the batch cost row itself with `create_many(skip_duplicates=True)` and only the retrieve whose insert lands charges the key, team, and user. An existing row only takes the charge when it is a successful `aretrieve_batch` row, so a client-chosen `x-litellm-call-id` on another endpoint cannot suppress billing. Batch cost rows no longer get their own immediate flush path `batch_cost_is_final` now treats the proxy's normalized `complete` status like `completed`, which the enterprise batch cost poller relies on when it decides whether a completed batch is safe to retire. Tests build that status with `model_copy` since the OpenAI `Batch` model rejects it The `test-quality-ok` markers sit on the `patch(` lines the gate keys on, and the logging tests no longer wrap the priced retrieve in `contextlib.suppress` --- litellm/batches/batch_utils.py | 5 +- litellm/proxy/db/db_spend_update_writer.py | 73 ++++++++-- .../proxy/hooks/proxy_track_cost_callback.py | 68 +++------- litellm/proxy/utils.py | 10 +- .../test_litellm/batches/test_batch_utils.py | 14 +- .../test_litellm_logging.py | 12 +- .../proxy/db/test_db_spend_update_writer.py | 128 +++++++++++++++++- .../hooks/test_proxy_track_cost_callback.py | 116 ++++------------ .../prisma_and_spend/test_spend_functions.py | 15 -- 9 files changed, 249 insertions(+), 192 deletions(-) diff --git a/litellm/batches/batch_utils.py b/litellm/batches/batch_utils.py index eaac3bf0e9f..959c7498479 100644 --- a/litellm/batches/batch_utils.py +++ b/litellm/batches/batch_utils.py @@ -25,7 +25,8 @@ class BatchCostUsageResult: failed_requests: int -_TERMINAL_BATCH_STATUSES: Final = frozenset({"completed", "failed", "cancelled", "expired"}) +_COMPLETED_BATCH_STATUSES: Final = frozenset({"completed", "complete"}) +_TERMINAL_BATCH_STATUSES: Final = _COMPLETED_BATCH_STATUSES | frozenset({"failed", "cancelled", "expired"}) def batch_cost_is_final(batch: Batch) -> bool: @@ -39,7 +40,7 @@ def batch_cost_is_final(batch: Batch) -> bool: """ if batch.status not in _TERMINAL_BATCH_STATUSES: return False - if batch.status != "completed" or batch.output_file_id is not None: + if batch.status not in _COMPLETED_BATCH_STATUSES or batch.output_file_id is not None: return True request_counts: Final = batch.request_counts return request_counts is not None and request_counts.total > 0 and request_counts.completed == 0 diff --git a/litellm/proxy/db/db_spend_update_writer.py b/litellm/proxy/db/db_spend_update_writer.py index ff48b00dc70..3fad351224b 100644 --- a/litellm/proxy/db/db_spend_update_writer.py +++ b/litellm/proxy/db/db_spend_update_writer.py @@ -82,7 +82,10 @@ else: RESPONSES_SESSION_CALL_TYPES: Final = frozenset({CallTypes.responses.value, CallTypes.aresponses.value}) -IMMEDIATE_FLUSH_CALL_TYPES: Final = RESPONSES_SESSION_CALL_TYPES | frozenset({CallTypes.aretrieve_batch.value}) + + +def _is_batch_cost_row(payload: SpendLogsPayload) -> bool: + return payload.get("call_type") == CallTypes.aretrieve_batch.value and payload.get("status") == "success" class _SpendBatch(Protocol): @@ -216,7 +219,12 @@ class DBSpendUpdateWriter: start_time: datetime | None, end_time: datetime | None, response_cost: float | None, - ) -> None: + ) -> bool: + """Record the request's spend, answering whether its cost still needs charging. + + False only for a batch retrieve whose cost row another retrieve already wrote, + so the caller leaves the key, team, and user counters alone (LIT-7048). + """ from litellm.proxy.proxy_server import ( disable_spend_logs, litellm_proxy_budget_name, @@ -233,7 +241,7 @@ class DBSpendUpdateWriter: team_id, ) if ProxyUpdateSpend.disable_spend_updates() is True: - return + return True if token is not None and isinstance(token, str) and token.startswith("sk-"): hashed_token = hash_token(token=token) else: @@ -264,10 +272,8 @@ class DBSpendUpdateWriter: payload["team_id"] = team_id if disable_spend_logs is False: - await self._insert_spend_log_to_db( - payload=payload, - prisma_client=prisma_client, - ) + if not await self._record_spend_log(payload=payload, prisma_client=prisma_client): + return False await self._enqueue_tool_usage_transaction( payload=payload, completion_response=completion_response, @@ -307,6 +313,7 @@ class DBSpendUpdateWriter: ) verbose_proxy_logger.debug("Runs spend update on all tables") + return True except Exception: spend_log_error( "Spend tracking - update_database failed.

Covering it directly also turned up a hole. litellm._should_retry compares the status code to 500, so a provider exception carrying a string status code raises TypeError instead of answering. should_retry_this_error has the same call, but the retry policy path skips it, which is exactly the path this change enables, so the helper was the first to touch that value.

Job names are now evaluated per matrix combination over the pieces a name can hold: string literals, `matrix.`, `format()`, `==` and `!=`, and the ` && || ` idiom. All 33 required contexts now resolve, and nothing in the repo leaves an expression unresolved. An expression the evaluator does not understand still falls back to its verbatim template, so two jobs sharing one stays a collision.

It asked that question at the group's minimum order, but the router picks the retry's deployment at the order the request has already escalated to. So a group with a primary at order 1 and a backup at order 2 answered "yes, order 1 still has a candidate" while the retry was pinned to order 2, and the exclusion left order 2 with nothing. The caller got a no-deployments error in place of the provider's own 400.

Every read now goes through one narrowing function that keeps a tuple of strings and skips nothing otherwise, so a forged value costs the caller nothing beyond the retry landing on the same deployment again. --- litellm/router.py | 11 +++++---- tests/test_litellm/test_router.py | 39 +++++++++++++++++++++++++++++++ 2 files changed, 46 insertions(+), 4 deletions(-) diff --git a/litellm/router.py b/litellm/router.py index 93178dc8e26..e42bc2af398 100644 --- a/litellm/router.py +++ b/litellm/router.py @@ -401,7 +401,10 @@ def _stream_chunks_have_generated_content(chunks: Sequence[ModelResponseStream]) _NO_SESSION_KWARGS: Final[Mapping[str, Mapping[str, object]]] = MappingProxyType({}) _SESSION_ADAPTER: Final = TypeAdapter(Mapping[str, object]) -_SKIPPED_DEPLOYMENT_IDS_ADAPTER: Final = TypeAdapter(tuple[str, ...]) + + +def _as_retry_skipped_deployment_ids(value: object) -> tuple[str, ...]: + return tuple(item for item in value if isinstance(item, str)) if isinstance(value, tuple) else () def _with_router_resolved_session_model(session: object, model_name: str) -> Mapping[str, Mapping[str, object]]: @@ -7467,7 +7470,7 @@ class Router: return () if litellm._should_retry(status_code): # pyright: ignore[reportPrivateUsage] # as in should_retry_this_error return () -

That missed real duplicates and invented ones that don't exist. It also crossed every matrix value while ignoring `exclude`, so it checked combinations no job ever runs. Four smaller gaps went with it. Boolean matrix values reached a name as `True` rather than `true`. A `format()` whose arguments cannot fill its placeholders raised straight out of the script instead of leaving the name unresolved. A job calling a reusable workflow only ever chained one level, and a call outside the repo fell back to the caller's own name, which GitHub never posts.

Neither checked the thing an operator actually looks at afterwards: the audit trail. Adds an e2e test asserting the spend log carries the pre_call guardrail record for a masked request: status, provider, per-entity masked counts, and the detected-entity list the dashboard's guardrail panel renders its scores from. It keys off the x-litellm-applied-guardrails response header rather than masked text in the answer, because whether the model echoes the prompt back is a model decision, not a guardrail one. Both a mutation that stops writing the record and one that empties the entity list turn it red. Two records land on one log, pre_call and post_call, so the assertion selects on mode as well as name; picking by name alone could hand it the empty post_call record depending on write order. On the UI side, the Presidio wizard test now reads the stored guardrail back and asserts every persisted entity carries the MASK action. A row appearing in the table did not prove the entity selection survived the save, so a wizard that persisted an empty pii_entities_config would have passed. SpendLogRow gains a typed metadata field. guardrail_response is left as object because each provider writes its own shape there (presidio a list of entities, bedrock an assessment object, a failed run the exception string); a union narrow enough to be useful would fail to parse the others and break every suite that reads a spend log. The caller validates the shape it expects with a TypeAdapter. run_e2e.sh now pins PROXY_BASE_URL to the stack's own origin. The proxy builds its post-login redirect from that variable when it is set, so a value inherited from a developer's .env sent the browser off the relocated stack and the suite's login step timed out on every port but 4000. --- tests/e2e/coverage_registry/guardrail.yaml | 1 + .../guardrails/test_presidio_masking_e2e.py | 124 +++++++++++++++++- tests/e2e/models.py | 22 ++++ tests/e2e/ui/run_e2e.sh | 1 + .../ui/tests/guardrails/guardrails.spec.ts | 12 ++ 5 files changed, 156 insertions(+), 4 deletions(-) diff --git a/tests/e2e/coverage_registry/guardrail.yaml b/tests/e2e/coverage_registry/guardrail.yaml index c64fd6150af..81832bebf49 100644 --- a/tests/e2e/coverage_registry/guardrail.yaml +++ b/tests/e2e/coverage_registry/guardrail.yaml @@ -3,6 +3,7 @@ - {id: guardrail.presidio.pre_call.masks, module: guardrail, tier: P0, hook_point: pre_call, assertions: [masks], exercised_on: [chat_completions, messages], source: "guardrail_hooks/presidio.py", rationale: "PII masking pre-call;

Drop the exception entirely: a name still holding an expression is one GitHub resolves per job, so it is nothing to compare, which is what the rest of the module already does. `format()` was resolved with Python's semantics, so an attribute lookup crashed the script and a width specifier padded a name GitHub never pads.

Nothing covered that path, so a break anywhere along it surfaced only when someone happened to repeat the steps. Adds a spec that walks it once and turns the eyeball checks into assertions. The strongest of them is the leak check: it reads the request back and fails if the stored prompt still carries the raw address or number, which is what the manual step is really looking for. The stack gains a Presidio stand-in that answers the two routes the guardrail calls, detecting a fixed regex set with a Luhn check on card numbers. Real Presidio's detection quality is Presidio's business, and pinning the UI lane to it would mean two heavy containers with spaCy models on every CI run for a test that is about LiteLLM's integration. The real analyzer stays covered in the Python lane. The stand-in returns the same entities at the same spans as the real one for the checklist's sentence, and driving the real guardrail against it produces the same record shape, so a test written against it is written against the product's real behavior. Making the stand-in return the text unmasked turns the spec red on the raw address reaching the spend log, so the leak assertion reads live data. run_e2e.sh and both CircleCI UI jobs start the stand-in alongside the mock LLM. Its port is overridable like the others so two checkouts can run at once. --- .circleci/config.yml | 8 + tests/e2e/ui/constants.ts | 2 + .../fixtures/mock_presidio_server/server.py | 107 ++++++++++++ tests/e2e/ui/run_e2e.sh | 21 ++- .../guardrails/presidioUserStory.spec.ts | 158 ++++++++++++++++++ 5 files changed, 292 insertions(+), 4 deletions(-) create mode 100644 tests/e2e/ui/fixtures/mock_presidio_server/server.py create mode 100644 tests/e2e/ui/tests/guardrails/presidioUserStory.spec.ts diff --git a/.circleci/config.yml b/.circleci/config.yml index 6e368a3debe..276555c0cf7 100644 --- a/.circleci/config.yml +++ b/.circleci/config.yml @@ -2648,6 +2648,10 @@ jobs: name: Start mock LLM server command: uv run --no-sync python tests/e2e/ui/fixtures/mock_llm_server/server.py background: true + - run: + name: Start mock Presidio server + command: uv run --no-sync python tests/e2e/ui/fixtures/mock_presidio_server/server.py + background: true - run: name: Start LiteLLM proxy environment: @@ -2778,6 +2782,10 @@ jobs: name: Start mock LLM server command: uv run --no-sync python tests/e2e/ui/fixtures/mock_llm_server/server.py background: true + - run: + name: Start mock Presidio server + command: uv run --no-sync python tests/e2e/ui/fixtures/mock_presidio_server/server.py + background: true - run: name: Start LiteLLM proxy under a server root path environment: diff --git a/tests/e2e/ui/constants.ts b/tests/e2e/ui/constants.ts index 3a62252915c..71774c95d24 100644 --- a/tests/e2e/ui/constants.ts +++ b/tests/e2e/ui/constants.ts @@ -15,6 +15,8 @@ export const UI_BASE_URL = ( // writable path (the image runner already exports TMPDIR) to relocate them. export const ARTIFACT_DIR = process.env.E2E_UI_ARTIFACT_DIR || ".";

Both were the same defect in different places: the Logs drawer renders several nodes per string and the first in DOM order is often hidden, so .first() waited 20s on an invisible element. The entity assertions had a second problem on top, since getByText("EMAIL_ADDRESS") substring-matched the masked prompt div, whose text contains , rather than the entity chip. Route every drawer assertion through onlyVisible, and match the entity type and score exactly, which is what the panel renders them as: entity_type and "Score: N.NN" each get their own span. Verified on a live stack: 6 of 6 solo runs and the guardrails folder 5 of 5. Mutating the analyzer to detect nothing turns the spec red on the raw address reaching the spend log, so the assertions still carry their weight. --- .../guardrails/presidioUserStory.spec.ts | 20 +++++++++---------- 1 file changed, 10 insertions(+), 10 deletions(-) diff --git a/tests/e2e/ui/tests/guardrails/presidioUserStory.spec.ts b/tests/e2e/ui/tests/guardrails/presidioUserStory.spec.ts index ff4d6260312..d4ed5308342 100644 --- a/tests/e2e/ui/tests/guardrails/presidioUserStory.spec.ts +++ b/tests/e2e/ui/tests/guardrails/presidioUserStory.spec.ts @@ -137,17 +137,17 @@ test.describe("Presidio PII guardrail, end to end from the dashboard", () => { await row.click(); const drawer = page.getByRole("dialog").first(); - await expect(drawer.getByText("Guardrails & Policy Compliance")).toBeVisible({ timeout: 20_000 }); - await expect(drawer.getByText(`Pre-call guardrail: ${guardrailName}`).first()).toBeVisible({ timeout: 20_000 }); - const maskedPrompt = onlyVisible(drawer.getByText(`${marker}.

The synthetic request built for MCP tool call guardrail hooks carried no guardrails in its metadata, so a guardrail with default_on false never ran on tools/call even when the key explicitly listed it. Resolve key, team, and project guardrails onto the synthetic request with the same helper the chat path uses. * fix(mcp): pass project metadata through without a mutable default * fix(mcp): mark the

contracts for key, model and MCP server forms Add vitest cases that pin what the key edit, key create, model edit and MCP server edit forms put on the wire: an edited field reaches the request with its new value, a cleared field reaches it as an explicit null, and the dirty-only body is pinned as an expected failure until each form moves to pickDirty. Model edit also pins the cost-map-derived model_info fields as an expected failure. KeyEditView hands a cleared max_budget to KeyInfoView as an empty string and handleKeyUpdate maps it to null, so the null is pinned at the /key/update boundary in key_info_view.test.tsx and the KeyEditView case is an expected failure. buildEditServerPayload passes a cleared description through as an empty string, so that case is an expected failure too. * test(ui): split masked model_info pins and retarget the create tracker The model_info expected-failure case held three assertions, and it.fails stops at the first one, so a later revamp that fixed max_input_tokens while leaving mode leaking would still report an expected failure. Split it into one case per pinned field group so each flips on its own. The key create tracker asserted a body of only key_alias, which a create can never send: key_type, user_id, duration and metadata are always mounted. Retarget it at the real over-send, which is the Optional Settings section adding fifteen undefined-valued keys when the user opens it without filling anything in. --- .../editServerPayload.differential.test.ts | 43 ++++++++++- .../src/components/model_info_view.test.tsx | 72 +++++++++++++++++++ .../create_key_button.integration.test.tsx | 31 ++++++++ .../templates/key_edit_view.test.tsx | 52 ++++++++++++++ .../templates/key_info_view.test.tsx | 10 +++ 5 files changed, 207 insertions(+), 1 deletion(-) diff --git a/ui/litellm-dashboard/src/app/(dashboard)/mcp-servers/_components/editServerPayload.differential.test.ts b/ui/litellm-dashboard/src/app/(dashboard)/mcp-servers/_components/editServerPayload.differential.test.ts index f9cab181e71..66786fac1c3 100644 --- a/ui/litellm-dashboard/src/app/(dashboard)/mcp-servers/_components/editServerPayload.differential.test.ts +++ b/ui/litellm-dashboard/src/app/(dashboard)/mcp-servers/_components/editServerPayload.differential.test.ts @@ -12,7 +12,7 @@ import { } from "@/components/mcp_tools/types"; import { AUTH_TYPES_REQUIRING_CREDENTIALS } from "./createServerPayload"; import { TOOL_DISPLAY_NAME_PATTERN, normalizeEnvVars } from "./utils"; -import { buildEditServerPayload, type EditServerUiState } from "./editServerPayload"; +import { buildEditServerPayload, type EditServerFormValues, type EditServerUiState } from "./editServerPayload"; import { CASES, baseUi } from "./editServerPayload.differential.cases"; // GENERATED by scratchpad/emit_test.py.

Ids now carry a random suffix. Also move the member-permissions setup inside the cleanup-protected block so a half-finished setup cannot leak a team, and close both browser contexts the test opens. --- .../proxy-admin/teamGuardrailRemoval.spec.ts | 145 ++++++++++++++ .../tests/proxy-admin/teamMemberEdit.spec.ts | 129 +++++++++++++ .../team-admin/memberPermissions.spec.ts | 177 ++++++++++++++++++ 3 files changed, 451 insertions(+) create mode 100644 tests/e2e/ui/tests/proxy-admin/teamGuardrailRemoval.spec.ts create mode 100644 tests/e2e/ui/tests/proxy-admin/teamMemberEdit.spec.ts create mode 100644 tests/e2e/ui/tests/team-admin/memberPermissions.spec.ts diff --git a/tests/e2e/ui/tests/proxy-admin/teamGuardrailRemoval.spec.ts b/tests/e2e/ui/tests/proxy-admin/teamGuardrailRemoval.spec.ts new file mode 100644 index 00000000000..f7930378b1e --- /dev/null +++ b/tests/e2e/ui/tests/proxy-admin/teamGuardrailRemoval.spec.ts @@ -0,0 +1,145 @@ +import { test, expect, type APIRequestContext, type Page as PlaywrightPage } from "@playwright/test"; +import { ADMIN_STORAGE_PATH } from "../../constants"; +import { Page } from "../../fixtures/pages"; +import { navigateToPage, dismissFeedbackPopup, clickTeamId } from "../../helpers/navigation"; +import { proxyIsPremium } from "../../helpers/premium"; +import { readBack } from "../../helpers/roundTrip"; +import { CHAT_MODEL_A, MOCK_RESPONSE_TEXT, masterKey } from "../../helpers/traffic"; + +const auth = () => ({ Authorization: `Bearer ${masterKey()}` }); + +async function guardrailId(request: APIRequestContext, name: string): Promise { + const res = await request.get("/v2/guardrails/list", { headers: auth() }); + expect(res.ok(), `GET /v2/guardrails/list (${res.status()})`).toBe(true); + const rows = (await res.json()).guardrails as { guardrail_id: string; guardrail_name: string | null }[]; + return rows.find((row) => row.guardrail_name === name)?.guardrail_id; +} + +async function teamGuardrails(page: PlaywrightPage, teamId: string): Promise { + const body = await readBack<{ team_info: { metadata: { guardrails?: string[] } | null } }>( + page, + `/team/info?team_id=${encodeURIComponent(teamId)}`, + ); + return body.team_info.metadata?.guardrails ??

From: yuneng-jiang Date: Mon, 7 Sep 2026 11:30:46 -0700 Subject: [PATCH 104/123] test(e2e): prove the virtual key lifecycle on every gateway replica (#40023) * test(e2e): prove the virtual key lifecycle on every replica Walks one virtual key through create, read, partial update, clear, enforce and delete against a live proxy and database, reading every write back on every gateway replica. The management suite already had single write-then-read tests for keys, but none of them proved that a partial /key/update leaves the untouched fields alone, that an explicit null clears a field, or that a write is visible on more than the one gateway that took it. Adds read_back_everywhere to the shared ProxyClient: it polls a GET path on every URL in PROXY_REPLICA_URLS until each replica's parsed body satisfies the caller's predicate, and fails naming the replica that never converged. The CLEAR sentinel in the e2e models makes an explicit JSON null expressible in a body the transport otherwise strips of None fields. Documents /key/update's merge patch semantics on the endpoint docstring. * test(e2e): prove key revocation and field preservation on every replica Applies the findings from an adversarial review of the first commit. The delete step only checked that chat was refused on the gateway that took the write, so it would have passed while a sibling gateway kept serving the deleted key. It now serves one call from every replica first, so each has the key cached and the delete has something to revoke everywhere, then polls every replica for the refusal. The file also carried its own poll loop that tested the deadline before attempting, so it gave up one attempt early and skipped the attempt landing exactly on the deadline. It now shares the harness helper, which is generic over the polled value rather than over a parsed body, so the same loop covers both the info read-back and the chat refusal. The model the enforcement step registers now carries a unique marker in its alias, matching every other deployment this suite creates, so concurrent runs never share one model group. The docstring sentence claimed an explicit null clears any field. It does not: the metadata-backed fields merge into stored metadata, where a null is a silent no-op, and only the key's own columns clear. Regenerating the dashboard types picks up the corrected text. * fix(e2e): delete a deployment that never becomes servable Registering a model posts /model/new and then waits for every replica to list it. When that wait timed out the deployment already existed in the database but its id had never been returned, so no caller could delete it and the row outlived the run. It is now deleted before the failure propagates. Found by review on the key lifecycle suite, whose module fixture registers a deployment this way, but every caller of the shared helper had the same exposure. * docs(e2e): drop the duplicated notes from the lifecycle docstrings The delete method restated what the warm-up helper already explains, and the module restated the merge patch rule that the endpoint and the request model both document. --- .../key_management_endpoints.py | 5 + tests/e2e/coverage_registry/mgmt.yaml | 2 + .../e2e/management/test_key_lifecycle_e2e.py | 299 ++++++++++++++++++ tests/e2e/models.py | 36 ++- tests/e2e/proxy_client.py | 152 ++++++++- tests/e2e/test_proxy_client.py | 114 ++++++- ui/litellm-dashboard/src/lib/http/schema.d.ts | 5 + 7 files changed, 592 insertions(+), 21 deletions(-) create mode 100644 tests/e2e/management/test_key_lifecycle_e2e.py diff --git a/litellm/proxy/management_endpoints/key_management_endpoints.py b/litellm/proxy/management_endpoints/key_management_endpoints.py index ebcfab090b5..8e51e250319 100644 --- a/litellm/proxy/management_endpoints/key_management_endpoints.py +++ b/litellm/proxy/management_endpoints/key_management_endpoints.py @@ -2840,6 +2840,11 @@ async def update_key_fn( """ Update an existing API key's parameters. + The body is a merge patch: a field left out keeps its stored value, and on the key's own columns + an explicit null clears it.

Add an opt-in outermost ASGI middleware that matches the request path against a configured prefix list (SERVER_ROOT_PATHS, comma-separated) on a segment boundary and sets scope["root_path"] for that request only. Everything downstream is stock Starlette: route matching strips root_path so routes stay registered root-relative, and request.base_url re-includes it, so the discovery documents' resource and the 401 challenges' resource_metadata land under the prefix the client actually called — with no discovery-builder changes. LazyFeatureMiddleware now strips the scope root_path (falling back to the cached SERVER_ROOT_PATH scalar) before feature prefix matching, so lazily-registered routers — the MCP OAuth discovery router among them — load under per-request prefixes. Follow-up to the routing discussion on #35226; composes with, but does not depend on, #35576. * fix(proxy): import Sequence from collections.abc (ruff UP035 strict-budget gate) * review(greptile): trim implementation commentary; fixture-own MCP registry state in tests Addresses both P2s from the first Greptile pass: - per_request_root_path_middleware.py (and the related _lazy_features / proxy_server comments) cut down to the constraints the code cannot express, per repo comment guidance - the new discovery tests no longer clear/repopulate the shared MCP registry inline; a fixture snapshots it, hands the test an empty registry, and restores it afterwards so no state leaks between cases * fix(lint): mutable-ok marker on the prefix accumulator (LIT002 type-discipline gate) * fix(proxy): tie 401 challenges and get_custom_url to the per-request root_path The per-request root_path middleware sets scope["root_path"] to the prefix the client actually called, but the OAuth 401 challenges (raise_user_oauth_challenge / raise_token_exchange_challenge) still built their resource_metadata from SERVER_ROOT_PATH. On a pod fronting several prefixes, the challenge advertised a discovery URL under a different prefix than the discovery document served — the two disagreed on where the resource metadata lives, and a strict RFC 9728 client refused the challenge. Route the challenges through a small ContextVar the middleware populates so they read the same effective root_path Starlette resolves the request under. The same accessor fixes get_custom_url: when a request lives under a SERVER_ROOT_PATHS-matched prefix, request.base_url already carries it, so appending the SERVER_ROOT_PATH scalar on top produced e.g. /tenant-a/legacy/sso/callback — a path that does not exist. Reading the per-request prefix instead (and relying on join_paths's tail-dedup) keeps SSO login/callback URLs under one prefix — the one the request actually arrived on. Fallback: outside a request (module-load-time UI URL builders, background tasks) the ContextVar is unset and the accessor reads SERVER_ROOT_PATH, matching get_server_root_path() so scalar-only deployments are byte-identical. * fix(mcp): challenge URL under per-request prefix must route, and mock parity Two follow-ups to the review fix that made the 401 challenge use the per-request root_path: 1. oauth_protected_resource_path must pick the URL structure that actually routes for the mechanism in use: - The scalar SERVER_ROOT_PATH deployment registers the well-known routes with the prefix INSERTED (via well_known_root_suffix at import time), matching RFC 8414 §3. The challenge URL must use the same insertion or a client fetching it 404s. - The per-request SERVER_ROOT_PATHS deployment can't register routes per prefix; PerRequestRootPathMiddleware strips the prefix from scope["path"] and the router matches the un-inserted route. The URL must place the prefix BEFORE .well-known so the strip leaves a matching path. The previous fix used the insertion form for both, which 404'd the discovery fetch on the per-request path — the discovery doc and the challenge would then disagree on where the resource metadata lives, the very failure the review flagged. End-to-end verified: the URL the challenge advertises routes and the doc's `resource` field equals the URL the client originally called (RFC 9728 §3). 2. get_request_root_path now delegates its fallback through get_server_root_path() instead of reading the env directly, so every existing `monkeypatch.setattr("litellm.proxy.utils.get_server_root_path"` test override keeps working. This unstubbed the mock on the /v2/login test that failed on the last CI run. Plus the lint budget: annotate the local accumulator Final, tag the scope["root_path"] rewrite as an intentional ASGI-contract mutation, tag the reused `path`/`root_path` rebinds in LazyFeatureMiddleware, and add reason strings to the two new PLC0415 lazy-import noqas. * test(mcp): pin the reviewer's expected end-state — challenge URL routes, resource matches called URL End-to-end regression test that mounts the discoverable router + the per-request root_path middleware, hits an MCP endpoint that raises raise_user_oauth_challenge, fetches the resource_metadata URL the challenge advertises, and checks the returned document's `resource` equals the URL the client originally called (RFC 9728 §3 exact match). Covers /tenant-a, /tenant-b, and the unprefixed path on the same app so a regression on any prefix — challenge URL 404s, or doc emits a different prefix than the client called — fails at this test rather than in a strict MCP client's discovery. --------- Co-authored-by: gym-cmd <186399764+gym-cmd@users.noreply.github.com> --- .../mcp_server/mcp_server_manager.py | 13 +- .../outbound_credentials/adapter.py | 26 +- .../proxy/_experimental/mcp_server/server.py | 8 +- litellm/proxy/_lazy_features.py | 19 +- .../per_request_root_path_middleware.py | 122 +++++++ litellm/proxy/proxy_server.py | 20 ++ litellm/proxy/utils.py | 14 +- .../outbound_credentials/test_adapter.py | 86 ++++- .../mcp_server/test_discoverable_endpoints.py | 224 +++++++++++++ .../test_per_request_root_path_middleware.py | 302 ++++++++++++++++++ tests/test_litellm/proxy/test_proxy_server.py | 76 +++++ .../proxy/utils/helpers/test_url_helpers.py | 73 +++++ 12 files changed, 948 insertions(+), 35 deletions(-) create mode 100644 litellm/proxy/middleware/per_request_root_path_middleware.py create mode 100644 tests/test_litellm/proxy/middleware/test_per_request_root_path_middleware.py diff --git a/litellm/proxy/_experimental/mcp_server/mcp_server_manager.py b/litellm/proxy/_experimental/mcp_server/mcp_server_manager.py index 612596bc803..e7fd650a324 100644 --- a/litellm/proxy/_experimental/mcp_server/mcp_server_manager.py +++ b/litellm/proxy/_experimental/mcp_server/mcp_server_manager.py @@ -163,7 +163,10 @@ from litellm.proxy.common_utils.user_api_key_cache import get_management_object_ from litellm.proxy.management_endpoints.sso.id_jag_assertion_capture import ( id_jag_assertion_capture_gap_at_startup, ) -from litellm.proxy.utils import PrismaClient, ProxyLogging, get_server_root_path +from litellm.proxy.middleware.per_request_root_path_middleware import ( + get_request_root_path, +) +from litellm.proxy.utils import PrismaClient, ProxyLogging from litellm.repositories.table_repositories import MCPServerRepository from litellm.types.llms.custom_http import httpxSpecialProvider from litellm.types.mcp import ( @@ -3858,7 +3861,7 @@ class MCPServerManager: if err.tag == "unauthorized" and isinstance(spec.config, AuthorizationCodeConfig): # authorization_code's missing per-user token -> the per-server browser-OAuth # challenge, built here where the full MCPServer is in hand. - raise_user_oauth_challenge(server, root_path=get_server_root_path()) + raise_user_oauth_challenge(server, root_path=get_request_root_path()) if err.tag == "unauthorized" and isinstance(spec.config, TokenExchangeConfig): # token_exchange (OBO): a missing/rejected subject token -> the RFC 9728 challenge # pointing at the IdP the client must SSO with to obtain one, rather than an opaque @@ -3866,7 +3869,7 @@ class MCPServerManager: # Access) threads its claims blob into the challenge for the client to satisfy. raise_token_exchange_challenge( server, - root_path=get_server_root_path(), + root_path=get_request_root_path(), claims=err.unauthorized.claims, ) raise_public(err) @@ -3914,7 +3917,7 @@ class MCPServerManager: if spec is None or not isinstance(spec.config, (TokenExchangeConfig, IdJagConfig)): return if subject_token is None and isinstance(spec.config, TokenExchangeConfig): - raise_token_exchange_challenge(resolved_server, root_path=get_server_root_path()) + raise_token_exchange_challenge(resolved_server, root_path=get_request_root_path()) match await self._cred_provider.resolve_credentials(to_subject(user_api_key_auth, subject_token), spec): case Ok(_): return @@ -3922,7 +3925,7 @@ class MCPServerManager: if err.tag == "unauthorized" and isinstance(spec.config, TokenExchangeConfig): raise_token_exchange_challenge( resolved_server, - root_path=get_server_root_path(), + root_path=get_request_root_path(), claims=err.unauthorized.claims, ) raise_public(err) diff --git a/litellm/proxy/_experimental/mcp_server/outbound_credentials/adapter.py b/litellm/proxy/_experimental/mcp_server/outbound_credentials/adapter.py index ea2318bd6f1..77979a15199 100644 --- a/litellm/proxy/_experimental/mcp_server/outbound_credentials/adapter.py +++ b/litellm/proxy/_experimental/mcp_server/outbound_credentials/adapter.py @@ -12,6 +12,7 @@ every other mode so the caller defers to v1 (parity-safe); it grows one branch p from __future__ import annotations import base64 +import os from typing import TYPE_CHECKING, Final, Literal, NoReturn from fastapi import HTTPException @@ -310,13 +311,30 @@ def raise_public(error: CredError) -> NoReturn: def oauth_protected_resource_path(root_path: str, server: MCPServer) -> str: """The server's RFC 9728 Protected Resource Metadata path, the shared anchor of both challenges. - ``root_path`` is the proxy's ``SERVER_ROOT_PATH``, resolved by the caller (the imperative shell) - so this stays a pure function of its inputs; ``"/"`` and ``""`` both mean no prefix.

Also fixes a pre-existing bug where create_skill() dropped description and instructions for the litellm_proxy provider, which left every LiteLLM-hosted skill with no searchable text. * fix(mcp): coerce skill_search top_k instead of raising 500 on malformed input The MCP-REST skill_search dispatch validated raw tool arguments through a pydantic model directly, so a non-numeric top_k raised a ValidationError that the endpoint's catch-all turned into an HTTP 500. Mirrors the agent_search branch's tolerant coerce_top_k handling instead. * fix(skills): enforce key limits on search embeddings and bound the semantic index Semantic search embeddings now run the same pre_call_hook the /embeddings route runs, so key rate limits, budgets and guardrails apply before the embedding model is called. The shared SemanticTextIndex caps cached vectors and evicts the least recently searched entries, and each skill's embedded text is capped so one skill cannot inflate the embedding batch Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(skills): surface proxy 429s from search embeddings instead of a 503 ProxyRateLimitError is also an OpenAIError, so the search engine was folding a key rate limit into skill_search_unavailable.

Neither wrapper forwarded `_response_headers`, so every streaming chat completion handed the proxy's callbacks and its response-header builder a wrapper with no provider headers, and a successful mid-stream fallback still published the failed deployment's identity, `x-request-id` and rate limit counters. Forward `_response_headers` into both wrappers, repoint the wrapper at the deployment that served the stream once a fallback takes over, and rebuild the proxy's response headers from that deployment while `create_response` still has the first chunk buffered. * fix(router): follow a nested fallback to the deployment that served the stream A fallback the router picks is itself a fallback-aware wrapper, and it only repoints at its own fallback once it yields, so reading its hidden params at selection time named a deployment that produced no output. Re-read them when the first fallback item arrives, which is still before the proxy commits response headers. Also addresses review feedback: the streaming header builder reads self.data instead of taking a coarse request_data parameter, and the new test recorder local is Final. * test(router): cover the fallback header adoption helper directly The router_code_coverage gate wants every router.py function named in a router test, and this also pins the weak-reference behavior: a wrapper collected mid-stream must not break the generator still draining it. * refactor(proxy): take a read-only mapping for the model-id lookup _get_model_id_from_response only reads its request payload, so a Mapping says what it needs and the two metadata hops are narrowed instead of assumed to be dicts. * test: drop mutable recorder locals and routine comments from the new tests An AsyncMock await_count and an asyncio.Event say the same thing as a list and a dict that the test mutates. * chore(router): justify the two rebinds in the fallback loops Both are the one-shot re-read that follows a nested fallback, so they get the repo's rebind-ok note like the rest of the file. --- litellm/proxy/common_request_processing.py | 126 ++-- .../pass_through_endpoints.py | 2 +- litellm/router.py | 83 ++- .../proxy/test_common_request_processing.py | 247 +++++++- tests/test_litellm/test_router.py | 574 ++++++++++++++++++ 5 files changed, 985 insertions(+), 47 deletions(-) diff --git a/litellm/proxy/common_request_processing.py b/litellm/proxy/common_request_processing.py index 5e6c9b34332..9720e4b1cf8 100644 --- a/litellm/proxy/common_request_processing.py +++ b/litellm/proxy/common_request_processing.py @@ -756,7 +756,7 @@ class _UpstreamClosingStreamingResponse(StreamingResponse): content: AsyncGenerator[str, None], *, media_type: str | None = None, - headers: dict | None = None, + headers: Mapping[str, str] | None = None, status_code: int = status.HTTP_200_OK, upstream_generator: AsyncGenerator[str, None] | None = None, ) -> None: @@ -888,25 +888,39 @@ def _sse_error_frames(error_obj: Mapping[str, object]) -> tuple[str, str]: return f"data: {json.dumps({'error': error_obj})}\n\n", "data: [DONE]\n\n" +def _sse_stream_headers(headers: Mapping[str, str]) -> Mapping[str, str]: + """`headers` plus the two that stop reverse proxies from buffering SSE (issue #28384).""" + return MappingProxyType({**headers, **_TTFT_KEEPALIVE_HEADERS}) + + +async def _resolve_stream_headers( + headers: Mapping[str, str], refresh_headers: Callable[[], Awaitable[Mapping[str, str]]] | None +) -> Mapping[str, str]: + if refresh_headers is None: + return headers + try: + return await refresh_headers() + except Exception as e: # noqa: BLE001 # a stream whose first chunk is already paid for must not fail over its headers + verbose_proxy_logger.exception("Error refreshing streaming response headers: %s", e) + return headers + + async def create_response( generator: AsyncGenerator[str, None], media_type: str, - headers: dict, + headers: Mapping[str, str], default_status_code: int = status.HTTP_200_OK, request: Request | None = None, + refresh_headers: Callable[[], Awaitable[Mapping[str, str]]] | None = None, ) -> StreamingResponse | JSONResponse: """ Create streaming response, checking if the first chunk is an error.

The entry carries no credential fields on purpose: the chatgpt backend ignores api_key and api_base and signs in through the device-code auth file on the proxy host, so any field here would be inert. Add a parity test that every LlmProviders value is either listed for Add Model or frozen in an explicit unlisted set, so a new backend provider cannot silently miss the dropdown again.
