From f776ea7f9bf491f458dcf5a570599d0e544ff4d3 Mon Sep 17 00:00:00 2001 From: Tin Chi Lo Date: Mon, 13 Jul 2026 19:25:37 -0700 Subject: [PATCH 01/90] feat(mcp): per-server outcomes for aggregate tools/list and truthful single-server REST statuses The aggregate MCP tools/list absorbed every per-server failure (upstream 401/403/5xx, timeouts, network errors) into that server contributing zero tools, making a broken upstream indistinguishable from a healthy server with no tools; the single-server REST list masked the same failures as {"tools": [], "error": null, "message": "Successfully retrieved tools"} Phase 2 of the MCP error-handling framework (LIT-4419): the manager fetch hops now raise a classified MCPServerListError (faults/list_outcomes.py: total classifier, frozen outcome values) instead of returning [], and each boundary applies the relay-vs-absorb policy matrix. The aggregate keeps serving the healthy subset but records each server's outcome, surfaced on the tools/list result _meta under litellm.ai/server_outcomes (the SDK passes a ListToolsResult through unwrapped) and in spend logs as per_server_list_outcomes. Single-server REST requests relay truthful statuses (unreachable/upstream_error 502, timeout 504, internal 500) and access denials now surface as real 403s instead of 200 unexpected_error bodies; upstream 403s surface through MCPUpstreamAuthError like 401s. Outcome wire values carry category and status code only, never upstream prose Resolves LIT-4421 --- .../_experimental/mcp_server/exceptions.py | 16 ++ .../mcp_server/faults/list_outcomes.py | 143 ++++++++++++++ .../mcp_server/mcp_server_manager.py | 35 ++-- .../mcp_server/rest_endpoints.py | 24 ++- .../proxy/_experimental/mcp_server/server.py | 107 +++++++---- .../_experimental/mcp_server/tool_search.py | 3 +- .../mcp_management_endpoints.py | 3 +- .../mcp/litellm_proxy_mcp_handler.py | 3 +- tests/mcp_tests/test_mcp_server.py | 21 +- .../mcp_server/faults/test_list_outcomes.py | 76 ++++++++ .../test_mcp_oauth_passthrough_tools.py | 27 +-- .../mcp_server/test_mcp_server.py | 181 +++++++++++++++--- .../mcp_server/test_mcp_server_manager.py | 77 +++++--- .../mcp_server/test_mcp_tool_search.py | 5 +- .../mcp_server/test_rest_endpoints.py | 91 +++++++-- .../mcp/test_litellm_proxy_mcp_handler.py | 5 +- 16 files changed, 669 insertions(+), 148 deletions(-) create mode 100644 litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py create mode 100644 tests/test_litellm/proxy/_experimental/mcp_server/faults/test_list_outcomes.py diff --git a/litellm/proxy/_experimental/mcp_server/exceptions.py b/litellm/proxy/_experimental/mcp_server/exceptions.py index 3e3e549008d..74752809e86 100644 --- a/litellm/proxy/_experimental/mcp_server/exceptions.py +++ b/litellm/proxy/_experimental/mcp_server/exceptions.py @@ -88,3 +88,19 @@ class MCPToolResultError(Exception): into two identities, breaking ``isinstance`` checks against instances created before the reload.

The stale _fetch_tools_with_timeout docstring describing the pre-change 403 absorb is rewritten to the actual contract: 403 relays with its own status, an upstream-sent challenge relays verbatim per RFC 6750 insufficient_scope, and a challenge is only ever fabricated for a challenge-less 401 --- .../mcp_server/faults/list_outcomes.py | 38 +++++++- .../mcp_server/mcp_server_manager.py | 90 +++++-------------- .../mcp_server/faults/test_list_outcomes.py | 55 ++++++++++++ .../mcp_server/test_mcp_server_manager.py | 72 +++++++++++++++ 4 files changed, 187 insertions(+), 68 deletions(-) diff --git a/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py b/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py index 4a189096e5c..ad360610d10 100644 --- a/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py +++ b/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py @@ -10,7 +10,7 @@ becomes an outcome, never a second failure. from __future__ import annotations -from typing import Literal, NamedTuple, TypeAlias +from typing import Literal, NamedTuple, NoReturn, TypeAlias import httpx from mcp.types import Tool as MCPTool @@ -87,6 +87,42 @@ def _find_upstream_response(exc: BaseException) -> httpx.Response | None: return None +def upstream_auth_challenge(exc: BaseException) -> tuple[int, str | None] | None: + """The upstream 401/403 and its ``WWW-Authenticate`` challenge, both read from the SAME response + the deliberate-order traversal selects, so the status that picks the carrier channel and the + challenge that rides with it can never come from two different responses in the tree.""" + response = _find_upstream_response(exc) + if response is None or response.status_code not in (401, 403): + return None + try: + challenge = response.headers.get("www-authenticate") + except Exception: + challenge = None + return response.status_code, challenge + + +def raise_classified_list_failure( + exc: BaseException, + server_name: str, + suppress_challenge: bool = False, +) -> NoReturn: + """The one place a failed server fetch chooses its carrier: an upstream 401/403 travels as + ``MCPUpstreamAuthError`` with the upstream's own challenge preserved (a challenge is only ever + fabricated at the HTTP edge, and only for a 401), everything else as ``MCPServerListError`` with + a classified fault.

Today litellm can inject those breakpoints server-side, but only when an admin hand-writes cache_control_injection_points into a model's litellm_params (or router_settings.default_litellm_params). Clients such as Claude Code and Claude Desktop never set cache_control themselves, and the admin recipe is easy to miss, so Anthropic traffic through the proxy silently pays full price on every repeated prefix. This adds an opt-in litellm_settings flag, enable_anthropic_prompt_caching. When it is on and the request has no injection points configured and no client-supplied cache_control, litellm synthesizes a default pair of breakpoints (the system prompt and the trailing turn) so the stable prefix is cached while the breakpoint advances with the conversation. It is wired into both surfaces: /chat/completions seeds the points before the existing prompt-management gate, and /v1/messages resolves them in maybe_inject_cache_control, so the existing AnthropicCacheControlHook applies them unchanged and keeps its four-block cap and its refusal to overwrite client breakpoints. The default is off, so no existing deployment changes behavior. Injection is gated to providers that actually consume cache_control markers (anthropic and bedrock) and to models the cost map flags as supporting prompt caching; note that supports_prompt_caching alone is not a sufficient gate, since OpenAI, Azure and Gemini models report it as well but never take cache_control markers. The default ttl is Anthropic's 5 minute ephemeral cache, with an optional anthropic_prompt_caching_ttl of "5m" or "1h"; ttl is also added to ChatCompletionCachedContent, which the bedrock and anthropic transforms already read at runtime but the type never declared Resolves LIT-4478 --- litellm/__init__.py | 2 + .../anthropic_cache_control_hook.py | 117 ++++++++++++++- .../messages/handler.py | 8 +- litellm/main.py | 25 ++++ litellm/types/llms/openai.py | 1 + .../test_anthropic_cache_control_hook.py | 136 ++++++++++++++++++ ui/litellm-dashboard/src/lib/http/schema.d.ts | 5 + 7 files changed, 291 insertions(+), 3 deletions(-) diff --git a/litellm/__init__.py b/litellm/__init__.py index 6e2a03b7c7c..c2a98497d62 100644 --- a/litellm/__init__.py +++ b/litellm/__init__.py @@ -315,6 +315,8 @@ disable_token_counter: bool = False disable_add_transform_inline_image_block: bool = False disable_add_user_agent_to_request_tags: bool = False disable_anthropic_gemini_context_caching_transform: bool = False +enable_anthropic_prompt_caching: bool = False +anthropic_prompt_caching_ttl: Optional[Literal["5m", "1h"]] = None disable_vertex_batch_output_transformation: bool = False extra_spend_tag_headers: Optional[List[str]] = None in_memory_llm_clients_cache: "LLMClientCache" diff --git a/litellm/integrations/anthropic_cache_control_hook.py b/litellm/integrations/anthropic_cache_control_hook.py index 608fdebc1d9..026d8b8e82e 100644 --- a/litellm/integrations/anthropic_cache_control_hook.py +++ b/litellm/integrations/anthropic_cache_control_hook.py @@ -296,18 +296,133 @@ class AnthropicCacheControlHook(CustomPromptManagement): return processed_messages, processed_system, remaining_points + @staticmethod + def _default_control() -> ChatCompletionCachedContent: + """Build the cache_control block for auto-injected breakpoints. + + Defaults to Anthropic's 5-minute ephemeral cache; honors the optional + ``litellm.anthropic_prompt_caching_ttl`` override ("5m" or "1h"). + """ + import litellm + + ttl = litellm.anthropic_prompt_caching_ttl + if ttl == "5m" or ttl == "1h": + return ChatCompletionCachedContent(type="ephemeral", ttl=ttl) + return ChatCompletionCachedContent(type="ephemeral") + + @staticmethod + def _request_has_cache_control(messages: list[AllMessageValues], system: Optional[Union[str, list]]) -> bool: + """Return True if the request already carries any client-supplied cache_control. + + When the client (e.g. Claude Code) already marks its own breakpoints we + stand down entirely rather than add more, per the auto-caching contract. + """ + if any(AnthropicCacheControlHook._count_cache_control_blocks(msg) for msg in messages): + return True + if isinstance(system, list): + return any(isinstance(block, dict) and block.get("cache_control") is not None for block in system) + return False + + @staticmethod + def get_default_injection_points( + messages: list[AllMessageValues], + system: Optional[Union[str, list]], + model: str, + custom_llm_provider: Optional[str], + ) -> list[CacheControlInjectionPoint]: + """Default breakpoints when ``litellm.enable_anthropic_prompt_caching`` is on. + + Caches the system prompt and the trailing turn, so the stable prefix + (system + tools + history) is reused while the breakpoint advances with + the conversation.

The expansion defaults to the Responses API tool shape, so a /chat/completions request came out carrying flat {"type": "function", "name": ...} entries where the provider transformations expect {"type": "function", "function": {...}}. Anthropic then raised KeyError: 'function' and Bedrock dropped every MCP tool silently, so the model answered as if no MCP server were connected. Replacing the reference also removed the marker the MCP gateway matches on, so acompletion_with_mcp never ran and tool calls were no longer auto-executed for require_approval="never", on /responses as well as /chat/completions. Narrow the reference through allowed_tools instead and leave it in place, so the gateway still owns expansion and keeps both the per-endpoint tool shape and tool auto-execution.

Because the header parser classifies any Authorization bearer as an OAuth token before the target server is resolved, a LiteLLM virtual key presented as Authorization: Bearer sk-... suppressed the challenge on a gateway-managed authorization_code server; the session then opened with no upstream token and tools/list masked the failure as 200 with an empty tool list. The same gate also wrongly challenged client_credentials (M2M) servers, which the gateway authenticates by minting its own token at egress. The decision is per oauth2 sub-mode, not per header. Gateway-managed modes never receive a client-supplied upstream token: client_credentials mints at egress so it is never challenged, and gateway-managed interactive (authorization_code, non-delegate) is challenged whenever no stored per-user token exists, regardless of any bearer.

Max budget: 0.25" even when no budget was configured anywhere. cli_poll_key stamped the minted CLI session token with litellm.max_ui_session_budget ($0.25) as a fallback whenever the user and team had no budget of their own. That cap was designed for the Admin UI "Test Key" chat pane; the CLI reused the same session-token machinery, so it inherited a playground-sized budget baked into the encrypted token at login (unchangeable without re-login), which trips fast under real CLI/agent use. The cap is also redundant: the token already carries user_id and team_id, so the real user/team budgets are enforced independently at request time. Pass max_budget=None so the CLI token is governed only by those real budgets, and drop the now-dead user/team budget lookups. The UI login token's guard (get_experimental_ui_login_jwt_auth_token) is untouched. --- litellm/proxy/management_endpoints/ui_sso.py | 42 ++----------------- .../proxy/management_endpoints/test_ui_sso.py | 29 +++---------- 2 files changed, 9 insertions(+), 62 deletions(-) diff --git a/litellm/proxy/management_endpoints/ui_sso.py b/litellm/proxy/management_endpoints/ui_sso.py index 0475566192e..6c2e06a418c 100644 --- a/litellm/proxy/management_endpoints/ui_sso.py +++ b/litellm/proxy/management_endpoints/ui_sso.py @@ -2092,12 +2092,8 @@ async def cli_poll_key( key_id: The CLI login session ID team_id: Optional team ID to assign to the JWT.

Addresses the Greptile P2 on this PR. Co-Authored-By: Claude Opus 4.8 (1M context) * test(e2e): widen the duplicate-settle window to 30s for real DataDog Against the local sink one poll interval (5s) after the first hit was enough to catch a same-call duplicate, because both events arrived in the same flush batch. Against real DataDog, ingestion jitter can make one call's two events searchable tens of seconds apart, so a 5s settle could let the LIT-4447 duplicate slip past the exactly-one assertion. The reader now keeps re-reading for DD_SETTLE_SECONDS (default 30s, env-overridable via E2E_DD_SETTLE_SECONDS) after the first event appears, returning early only when a duplicate is already visible - more waiting cannot clear it. Co-Authored-By: Claude Opus 4.8 (1M context) --------- Co-authored-by: Claude Opus 4.8 (1M context) * fix(e2e): point UI tests at dashboard service; register complexity router Stage gateway 404s /ui; the Next.js dashboard is litellm-ui:3000. Drive playwright against E2E_UI_BASE_URL and wait on login placeholders after client render. Register complexity-smart-router via /model/new when the proxy does not already list it so stage matches compose config * docs(e2e): clarify E2E_UI_BASE_URL should be ALB when ingress splits UI * docs(e2e): prefer single path-routing host for control plane and UI CONTROL_PLANE and UI already default to PROXY_BASE_URL; clarify that stage should set one ALB host rather than three endpoints * fix(e2e): always capture complexity router model_id for teardown Split /model/new from the data-plane wait so a propagation timeout still deletes the control-plane registration (greptile orphan-model concern) * fix(e2e): click exact Login button so SSO control is not matched Playwright strict mode matched both Login and Login with SSO * fix(router): score complexity by difficulty not request length The LLM classifier prompt treated short wording as SIMPLE, so probes like "Is P equal to NP?" stayed on the SIMPLE backend even though the classifier ran. Judge intellectual difficulty so short hard questions route higher * fix(e2e): open key edit via Key ID and wait for team models Key Alias text is not the row open control on the virtual keys table; KeyInfoView opens from the Key ID button in that row. Also wait for a real team model in the edit Models dropdown so we do not race the async availableModels fetch that only has All Team Models on first paint * fix(e2e): keep settled DD events on empty search; bump mcp for OSV Do not let a transient empty DataDog search wipe events already seen in the settle window (Greptile P1). Make the logs-search from window env-overridable via E2E_DD_SEARCH_FROM (Greptile P2). Prefer the mono Key ID button when opening key edit. Bump mcp 1.26.0 -> 1.28.1 so OSV clears the three high GHSA findings on the staging PR * revert: drop mcp lock bump from e2e staging PR OSV mcp upgrade is unrelated to the e2e fixes; leave the dep pin alone --------- Co-authored-by: yucheng-berri Co-authored-by: Claude Opus 4.8 (1M context) --- .../complexity_router/complexity_router.py | 10 +- tests/e2e/batches/capabilities.py | 40 +++++ tests/e2e/batches/test_batches_e2e.py | 18 ++- tests/e2e/docker-compose.yml | 63 +------- tests/e2e/e2e_config.py | 34 ++-- tests/e2e/logging/conftest.py | 9 +- tests/e2e/logging/datadog_reader.py | 150 ++++++++++++++++++ tests/e2e/logging/datadog_sink.py | 103 ------------ tests/e2e/logging/test_datadog_log_e2e.py | 40 +++-- tests/e2e/management/conftest.py | 20 ++- .../test_key_models_dropdown_e2e.py | 28 +++- tests/e2e/models.py | 1 + tests/e2e/router/conftest.py | 107 +++++++++++++ 13 files changed, 414 insertions(+), 209 deletions(-) create mode 100644 tests/e2e/logging/datadog_reader.py delete mode 100644 tests/e2e/logging/datadog_sink.py diff --git a/litellm/router_strategy/complexity_router/complexity_router.py b/litellm/router_strategy/complexity_router/complexity_router.py index e85987870e1..fa6f14e9b26 100644 --- a/litellm/router_strategy/complexity_router/complexity_router.py +++ b/litellm/router_strategy/complexity_router/complexity_router.py @@ -56,11 +56,13 @@ class TierClassification(BaseModel): _CLASSIFICATION_PROMPT_TEMPLATE = """Classify the complexity of the following user request into exactly one tier. +Judge the intellectual difficulty of answering correctly, not how short the request is. + Tiers: -- SIMPLE: factual lookups, greetings, short direct questions with no reasoning or code involved. -- MEDIUM: everyday requests needing some explanation or minor code/technical content. -- COMPLEX: requests involving non-trivial code, architecture, or multi-step technical work. -- REASONING: requests explicitly requiring step-by-step reasoning, analysis, or weighing tradeoffs. +- SIMPLE: greetings, chitchat, or factual lookups with a short known answer.

ba70189e328a5376700e9535d0629118857395e7 Mon Sep 17 00:00:00 2001 From: Tin Chi Lo Date: Thu, 16 Jul 2026 19:10:23 -0700 Subject: [PATCH 27/90] fix(router): resolve prompt cache minimum per model instead of a flat 1024 MINIMUM_PROMPT_CACHE_TOKEN_COUNT was a flat 1024 described as "minimum number of tokens to cache a prompt by Anthropic". Anthropic's minimum cacheable prefix is per-model and ranges from 512 to 4096, and it can differ per platform for the same model, so one constant is wrong in both directions is_prompt_caching_valid_prompt gates PromptCachingDeploymentCheck, which is what optional_pre_call_checks: ["prompt_caching"] turns on. When it believes a prompt is cacheable, async_filter_deployments pins routing to whichever deployment previously served that prefix. For a prompt between 1024 and 4096 tokens on Opus 4.6, Opus 4.5 or Haiku 4.5, litellm judged it cacheable and constrained routing while the provider never cached it, so the pin cost load balancing for nothing. In the other direction Fable 5 caches from 512 tokens, so a 512 to 1024 token prefix was refused a pin it had earned The minimum now resolves from prompt_cache_min_tokens in the model cost map, which keeps it current with new models and lets the Bedrock override for Fable 5 fall out of the existing per-entry keys with no special casing. MINIMUM_PROMPT_CACHE_TOKEN_COUNT stays as a global escape hatch when explicitly set, and as the fallback for models the cost map has no entry for async_filter_deployments only ever receives the model group alias, never a model name, so it resolves the threshold from healthy_deployments instead. A group may mix models with different minimums, so it takes the max: a prompt is only treated as cacheable when it clears every member's minimum, because an unnecessary pin is the defect being fixed while a missed pin only forfeits an optimization Gemini context caching shares this gate and has the same defect; its entries are left unset so they keep today's behavior, tracked separately in LIT-4525 --- litellm/constants.py | 17 +- litellm/litellm_core_utils/env_utils.py | 16 + ...odel_prices_and_context_window_backup.json | 342 ++++++++++++------ .../prompt_caching_deployment_check.py | 27 +- litellm/types/utils.py | 3 + litellm/utils.py | 40 +- model_prices_and_context_window.json | 342 ++++++++++++------ .../test_prompt_caching_deployment_check.py | 158 ++++++++ tests/test_litellm/test_utils.py | 73 ++++ 9 files changed, 781 insertions(+), 237 deletions(-) create mode 100644 tests/test_litellm/router_utils/pre_call_checks/test_prompt_caching_deployment_check.py diff --git a/litellm/constants.py b/litellm/constants.py index 8e0a5cfe50f..e104c937a9b 100644 --- a/litellm/constants.py +++ b/litellm/constants.py @@ -2,7 +2,7 @@ import os import sys from typing import List, Literal, Optional -from litellm.litellm_core_utils.env_utils import get_env_int +from litellm.litellm_core_utils.env_utils import get_env_int, get_env_int_or_none DEFAULT_HEALTH_CHECK_PROMPT = str(os.getenv("DEFAULT_HEALTH_CHECK_PROMPT", "test from litellm")) AZURE_DEFAULT_RESPONSES_API_VERSION = str(os.getenv("AZURE_DEFAULT_RESPONSES_API_VERSION", "preview")) @@ -269,9 +269,18 @@ TOOL_POLICY_CACHE_TTL_SECONDS = int(os.getenv("TOOL_POLICY_CACHE_TTL_SECONDS", 6 MAX_SIZE_IN_MEMORY_QUEUE = int(os.getenv("MAX_SIZE_IN_MEMORY_QUEUE", int(LITELLM_ASYNCIO_QUEUE_MAXSIZE * 0.8))) MAX_IN_MEMORY_QUEUE_FLUSH_COUNT = int(os.getenv("MAX_IN_MEMORY_QUEUE_FLUSH_COUNT", 1000)) ############################################################################################### -MINIMUM_PROMPT_CACHE_TOKEN_COUNT = int( - os.getenv("MINIMUM_PROMPT_CACHE_TOKEN_COUNT", 1024) -) # minimum number of tokens to cache a prompt by Anthropic +# Providers will not cache a prefix below a minimum size.

The query is now '*:*marker*', which scans all attributes (the marker sits in messages.content); verified to return exactly the event for the call. - Rate limit: the Logs Search API budget is 2 requests per 10s org-wide (x-ratelimit-name logs_public_search_api). Polling at POLL_INTERVAL=5s sat exactly at the limit and the reader hard-failed on the first 429. Searches now pace at DD_SEARCH_INTERVAL (10s default) and a 429 backs off and retries up to 5 times; only non-429 failures stay hard fails. - Envelope status: DataDog re-derives the indexed event status from the parsed payload's status attribute ('success') and normalizes it to its OK severity, so the assertion expects 'ok', not the shipped 'info'. Live run: chat_completions and responses pass every assertion including the exact response-cost cross-check; messages red-pins the LIT-4447 duplicate for real (one call -> two sync-sweep copies + one async batch copy, same request id, confirmed in proxy debug logs). The duplicate is race-dependent, so the pin flickers until #33589 lands. Co-Authored-By: Claude Opus 4.8 (1M context) * test(e2e): datadog log delivery for streamed chat, messages, and responses Rewritten from the dd-sink version (original #33566) to judge delivery on what real DataDog ingested, matching the merged #33604 conversion: the dd_logs reader searches events back through the Logs Search API and the assertions validate the indexed envelope (source:litellm tag, ok status) and the StandardLoggingPayload fields under the event's attributes. Each streamed test drives one STREAMED call per route, asserts the stream actually streamed (event-stream content type, >0 chunks, no upstream error event), then pins exactly one DataDog event whose payload records stream=true, the aggregated token count, and a response_cost equal to the /spend/logs row for the call - a stream's headers ship before its cost exists, so the spend row is the cross-check anchor, and the spend row and DataDog event must also agree on total_tokens. Coverage registry: adds logging.datadog.stream.exports_metric exercised on chat_completions, messages, and responses.

Multi-window budget polls gpt-5.5 with max_tokens=1 instead of Claude so the reset wait stays under ALB target idle timeout rather than masking awselb 502s * test(e2e): require exactly one LLM-tier spend row for complexity router Keep alias membership for compose vs stage model names, but assert len(served) == 1 so a leaked classifier sub-call cannot pass. Also pin LIT-4521 skip and align LIT-4522/23/24 skip reasons * test(e2e): harden router callable probe and multi-window budget exhaustion _router_is_callable treated any non-success chat whose body lacked "Invalid model name" as callable, so an unpropagated probe key (401), a generic 502, or a connection reset let the session proceed and hit real "Invalid model name" failures inside the tests. Require a Success outcome instead; the reload-race 400 and every infra/auth error now correctly read as not-callable. The multi-window budget test capped the tight window at 3e-6, which gpt-5.5 exhausts on the first call but a cheaper CHEAP_OPENAI_MODEL might not within the 20-call loop, turning a reset test into a spurious "window never enforced" failure. Drop the tight cap to 1e-9 so the first billed call exhausts it regardless of model price; the roomy 1m window stays at 1.0 and never blocks. * test(e2e): use a tradeoff-decision prompt for the complexity router classifier "Is P equal to NP?" reads to the LLM classifier as a short yes/no question, so gpt-5.5 classified it SIMPLE and the request routed to the openai backend, which made the test fail even though the classifier was running. The tier definitions key on what the request demands, not how hard the answer is, and a short direct question maps to SIMPLE regardless of subject. Swap in "Should I pay off my mortgage early or invest the extra money instead?". It carries none of the heuristic scorer's reasoning/technical/code keywords and stays short, so heuristic scoring still lands SIMPLE (openai), but the LLM reads it as a decision that has to weigh tradeoffs and lands it above SIMPLE, which the config routes to anthropic. Any non-SIMPLE tier serves anthropic, so the classifier only has to avoid SIMPLE for the test to distinguish a real classifier run from the heuristic fallback. --- tests/e2e/CLAUDE.md | 4 +- .../count_tokens/test_vertex_ai.py | 1 + .../long_context_1m/test_anthropic.py | 1 + .../claude_code/long_context_1m/test_azure.py | 1 + .../long_context_1m/test_bedrock_converse.py | 1 + .../long_context_1m/test_bedrock_invoke.py | 1 + .../long_context_1m/test_vertex_ai.py | 1 + .../e2e/claude_code/passthrough/test_azure.py | 3 + .../pdf_input/test_bedrock_converse.py | 4 + .../thinking/test_bedrock_converse.py | 4 + .../e2e/claude_code/tool_search/test_azure.py | 1 + .../tool_search/test_bedrock_invoke.py | 4 + .../claude_code/tool_search/test_vertex_ai.py | 1 + tests/e2e/coverage_registry/README.md | 5 -- .../test_key_models_dropdown_e2e.py | 10 ++- .../budgets/test_multi_window_budget_e2e.py | 19 +++-- tests/e2e/router/conftest.py | 83 ++++++++++--------- .../e2e/router/test_complexity_router_e2e.py | 47 +++++++---- 18 files changed, 120 insertions(+), 71 deletions(-) diff --git a/tests/e2e/CLAUDE.md b/tests/e2e/CLAUDE.md index 5d16761ac44..0e1eafb5196 100644 --- a/tests/e2e/CLAUDE.md +++ b/tests/e2e/CLAUDE.md @@ -17,7 +17,7 @@ Each subdirectory under `tests/e2e/` is one suite, scoped to an endpoint family - `security/` - secret handling and log-leak protection - `router/` - routing and reliability behavior (fallbacks, cooldowns) - `gateway/` - proxy configuration only (`litellm-config.yml`); no tests -- `claude_code/` - the Claude Code compatibility matrix: drives the real `claude` CLI (and HTTP probes) against a proxy for each feature x provider cell, reporting tagged-union outcomes via the `compat_result` fixture; ships its own driver/builder/publisher and does not use the shared transport harness +- `claude_code/` - the Claude Code compatibility matrix: drives the real `claude` CLI (and HTTP probes) against a proxy for each feature x provider cell, reporting tagged-union outcomes via the `compat_result` fixture; ships its own driver/builder/publisher plus `_*_unit_tests/` trees, and does not use the shared transport harness ## Lay the pattern down in a class @@ -53,7 +53,7 @@ Each suite provides its own `client` fixture (see `llm_translation/passthrough_c Request and response bodies are typed pydantic models in `models.py`; only the fields a test reads are modelled, and nothing passes raw dicts.

exception tree The consolidation regressed the pre-existing walker semantics: _extract_upstream_auth_failure used to keep scanning until it found a 401/403, while the consolidated helper took the first response of any status and then tested it, so a causal 401 sitting behind an unrelated 5xx (retry attempts, multi-stream task groups) was misclassified as upstream_error and its challenge lost on the listing, tool-call, and probe paths. The traversal is now an iterator in deliberate order and each consumer applies its predicate over the stream: the auth scan takes the first 401/403 even behind non-auth responses, generic classification takes the first response, and classify_list_exception derives its auth arm from the same scan so the carrier choice and the classification can never disagree --- .../mcp_server/faults/list_outcomes.py | 49 ++++++++------ .../mcp_server/faults/test_list_outcomes.py | 64 +++++++++++++++++++ 2 files changed, 94 insertions(+), 19 deletions(-) diff --git a/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py b/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py index 96ff9443126..6f27c1c0472 100644 --- a/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py +++ b/litellm/proxy/_experimental/mcp_server/faults/list_outcomes.py @@ -10,6 +10,7 @@ becomes an outcome, never a second failure. from __future__ import annotations +from collections.abc import Iterator from typing import Literal, NamedTuple, NoReturn, TypeAlias import httpx @@ -61,12 +62,14 @@ class AggregateToolListing(NamedTuple): outcomes: dict[str, ServerOutcome] -def _find_upstream_response(exc: BaseException) -> httpx.Response | None: - """Walk the exception tree (``__cause__``/``__context__``/ExceptionGroup members) for an - ``httpx.Response``, mirroring how upstream failures surface through the MCP SDK's task groups. - Explicit links are searched first: each node's ``raise ... from`` cause, then group members in - raise order, then the incidental ``__context__`` chain, so a response raised while handling the - real failure can never shadow the response on the explicit causal chain.""" +def _iter_upstream_responses(exc: BaseException) -> Iterator[httpx.Response]: + """Yield every ``httpx.Response`` in the exception tree (``__cause__``/``__context__``/ + ExceptionGroup members) in deliberate order, mirroring how upstream failures surface through the + MCP SDK's task groups.

This made tag-based routing to distinct provider configs behind one alias impossible, surfacing as 401 'Not allowed to access model due to tags configuration' for the second tag. Each registry now holds a list of tag-scoped strategies and async_pre_routing_hook selects the entry whose tags match the request before classification, falling back to a default-tagged then first-registered entry. A repeat of the same (model_name, tags) pair is still rejected.

A concurrency gauge cannot live on a windowed counter: every window roll reset the counter to 1 while requests were still in flight, the completion decrements for those forgotten requests then drove the counter negative, and rejected requests left stranded increments that nothing released. Under sustained load a key with max_parallel_requests=5 let backend concurrency climb to the full client concurrency (observed 60 on a live proxy) while the proxy kept returning 429s for everyone else Replace the windowed counter with a per-slot registry (Redis sorted set of slot ids scored by acquire time, with an asyncio-locked in-memory fallback): admission atomically prunes expired slots and registers a new slot id only when in_flight + 1 <= limit, so rejected requests never occupy a slot; success, failure, and client-disconnect paths release exactly the slot id this request acquired (stashed in the request metadata channels), so a release without a matching acquire or a double-fired callback can never free another request's slot; and a slot leaked by a crashed worker is pruned individually after its TTL even under continuous traffic Resolves LIT-4259 Fixes #16011 * fix(proxy): release every acquired gauge and respect mirrored counts in the in-memory fallback Address review findings on the slot-registry gauge: the acquisition stash now carries the gauge counter keys alongside the slot id, so the release paths free the slot from every gauge it was registered under instead of hardcoding the api_key scope, and the disconnect release keys off the stashed acquisition instead of the key object's current max_parallel_requests configuration (which can change mid-request). The in-memory fallback now treats a cached integer (the count mirrored from the last successful Redis script call) as real occupancy, carrying it forward as a floored counter during a Redis outage instead of restarting from an empty registry * fix(proxy): release the parallel slot on proxy-level rejections async_post_call_failure_hook is the only callback that fires when a downstream hook (guardrail, budget check) rejects a request after the rate limiter's pre-call hook acquired a slot; async_log_failure_event is a completion-level callback and never runs for proxy-side rejections. Release the stashed acquisition at the top of the hook, before the TPM reservation guard, so those slots do not linger for the full slot TTL and wedge the key at its limit under moderate rejection rates. Clearing the acquisition marker keeps the release idempotent when a later failure callback runs in the same flow * test(proxy): cover success release, read-only count, Redis release mirror, and TPM rejection release Four behaviors of the slot-registry gauge had no direct test: a successful completion releasing exactly its acquired slot, read_only callers counting in-flight slots through the count script (and degrading to the local mirror when the script fails) without acquiring, the Redis release script mirroring returned counts into the local cache, and the TPM reservation rejection releasing the already-acquired slot before raising * style(proxy): use builtin generics and union syntax in new rate limiter annotations The slot-gauge code added Tuple/List/Dict and Optional[...] annotations, pushing the UP006 and UP045 strict-rule totals past their ceilings in ruff-strict-budget.json. Convert only the annotations this branch introduces to builtin generics and PEP 604 unions, leaving the rest of the module untouched. --- litellm/proxy/common_request_processing.py | 2 +- .../hooks/parallel_request_limiter_v3.py | 699 ++++++++++++++--- litellm/proxy/proxy_server.py | 2 +- litellm/proxy/utils.py | 12 +- .../hooks/test_parallel_request_limiter_v3.py | 700 ++++++++++++++++-- 5 files changed, 1242 insertions(+), 173 deletions(-) diff --git a/litellm/proxy/common_request_processing.py b/litellm/proxy/common_request_processing.py index 02bb66388ca..6547eea9cd7 100644 --- a/litellm/proxy/common_request_processing.py +++ b/litellm/proxy/common_request_processing.py @@ -2680,7 +2680,7 @@ class ProxyBaseLLMRequestProcessing: # on disconnect, so the nested iterator hook (which only sees # GeneratorExit on GC) cannot own the refund. if not stream_completed: - proxy_logging_obj._release_max_parallel_requests_on_disconnect(user_api_key_dict) + proxy_logging_obj._release_max_parallel_requests_on_disconnect(user_api_key_dict, request_data) client_disconnected = True if not delivered_chunk: from litellm.proxy.spend_tracking.budget_reservation import ( diff --git a/litellm/proxy/hooks/parallel_request_limiter_v3.py b/litellm/proxy/hooks/parallel_request_limiter_v3.py index d60c17c744f..22ea9fe176a 100644 --- a/litellm/proxy/hooks/parallel_request_limiter_v3.py +++ b/litellm/proxy/hooks/parallel_request_limiter_v3.py @@ -7,6 +7,7 @@ This is currently in development and not yet ready for production. import asyncio import binascii import os +import uuid from datetime import datetime from typing import ( TYPE_CHECKING, @@ -185,6 +186,69 @@ end return results """ +PARALLEL_ACQUIRE_SCRIPT = """ +-- Atomic check-and-acquire for the max_parallel_requests concurrency gauge. +-- Each gauge key is a sorted set of per-request slot ids scored by acquire +-- time (Redis server clock).

Mon Sep 17 00:00:00 2001 From: Yassin Kortam Date: Fri, 17 Jul 2026 10:03:03 -0700 Subject: [PATCH 40/90] fix(proxy): stop treating upstream model body field as a LiteLLM model on auth-enforced pass-through routes (#33710) * fix(proxy): stop treating upstream model body field as a LiteLLM model on auth-enforced pass-through routes An auth: true user-defined pass-through endpoint runs full virtual-key auth, and get_model_from_request unconditionally extracted the request body model field, so key/team/user/project model allowlist checks rejected requests whose model only exists upstream (key_model_access_denied), even when the key was explicitly granted the route via allowed_passthrough_routes. The pass-through route registry moves to a leaf module (route_registry.py) that the auth layer can import without re-entering the pass_through_endpoints -> user_api_key_auth -> auth_utils import cycle. get_model_from_request now returns None for routes registered as user-defined pass-through endpoints (exact and subpath), which skips model allowlist and per-model budget enforcement on those routes while key auth, allowed_passthrough_routes, and spend/budget checks stay intact. Built-in provider passthrough routes (/vertex_ai, /gemini, ...) keep model enforcement. Resolves LIT-4299 * fix(proxy): key pass-through model-access skip on the dispatched endpoint, not the request path Addresses a model-authorization bypass: the first version decided whether to skip model-allowlist extraction by matching the request path against the pass-through route registry. That ignored the HTTP method and, more importantly, whether the request was actually dispatched to a pass-through handler. A custom pass-through whose path collides with a built-in route (e.g. /v1/chat/completions, or an include_subpath prefix of one) still writes a registry entry even though FastAPI serves the built-in handler, so a normal request to that route had its model checks skipped and could reach a model outside the key/team/user/project allowlist. The skip is now keyed off the FastAPI-resolved endpoint. create_pass_through_route tags its handler with LITELLM_PASS_THROUGH_ENDPOINT_MARKER, and get_model_from_request returns None only when request.scope["endpoint"] carries that marker. Because routing runs before auth dependencies, this reflects the handler that actually serves the request: on a collision the built-in handler is dispatched and carries no marker, so model enforcement stays on. This also removes the need for the separate route_registry module, so that extraction is reverted. Regression tests cover a pass-through-dispatched request (model suppressed), a built-in-dispatched request on the same path (model still enforced), and the no-request budget path.

Defaults to ['LITELLM ESCALATE'] when unset, case-sensitive so it only fires on the deliberate shouted form; admins can override the list or set [] to disable. Escalation applies across every routing path: heuristic/LLM classification, literal and semantic keyword_tier_rules overrides, adaptive routing, and session affinity (where it bumps relative to the pinned model and persists the higher tier for the rest of the session). Capped at the highest configured tier and skips unconfigured intermediate tiers. Expose it in the Auto-Router v2 UI as an Escalation Keywords field wired into the complexity_router_config payload.

-0700 Subject: [PATCH 46/90] feat(ui): configure Anthropic automatic prompt caching from the Admin UI Register enable_anthropic_prompt_caching and anthropic_prompt_caching_ttl on the General Settings table so caching can be turned on without hand-writing config. The registry could not express either field: validation was hardcoded to a float in (0, 1], reset set every field to None (not a bool for a boolean flag), and the listing reported any non-None value as 'In Config', which a False default would always trip. Validation now dispatches on the declared type and reset restores each field's own default. ConfigList carries field_options so the table can render a Select for enums instead of no editor at all. --- litellm/proxy/_types.py | 3 +- litellm/proxy/proxy_server.py | 96 +++++++-- tests/test_litellm/proxy/test_proxy_server.py | 204 ++++++++++++++++++ .../_components/general_settings.tsx | 15 +- ui/litellm-dashboard/src/lib/http/schema.d.ts | 2 + 5 files changed, 300 insertions(+), 20 deletions(-) diff --git a/litellm/proxy/_types.py b/litellm/proxy/_types.py index d102c1d1e37..e07c7b9ae78 100644 --- a/litellm/proxy/_types.py +++ b/litellm/proxy/_types.py @@ -1011,10 +1011,10 @@ class LiteLLM_ObjectPermissionBase(LiteLLMPydanticObjectBase): mcp_tool_search_enabled: Optional[bool] = None +from litellm.models.team import BudgetLimitEntry as BudgetLimitEntry # noqa: E402 from litellm.types.object_permission import ( # noqa: E402 ObjectPermissionDict as ObjectPermissionDict, ) -from litellm.models.team import BudgetLimitEntry as BudgetLimitEntry # noqa: E402 class GenerateRequestBase(LiteLLMPydanticObjectBase): @@ -2122,6 +2122,7 @@ class ConfigList(LiteLLMPydanticObjectBase): field_default_value: Any premium_field: bool = False nested_fields: Optional[List[FieldDetail]] = None # For nested dictionary or Pydantic fields + field_options: Optional[list[str]] = None # Allowed values, for field_type == "Select" class UserHeaderMapping(LiteLLMPydanticObjectBase): diff --git a/litellm/proxy/proxy_server.py b/litellm/proxy/proxy_server.py index dbdfdd5fdd3..ae91eb70427 100644 --- a/litellm/proxy/proxy_server.py +++ b/litellm/proxy/proxy_server.py @@ -28,6 +28,7 @@ from typing import ( Optional, Set, Tuple, + TypedDict, Union, cast, get_args, @@ -39,6 +40,7 @@ import anyio import websockets import websockets.exceptions from pydantic import BaseModel, Json, JsonValue +from typing_extensions import NotRequired, assert_never from litellm._uuid import uuid from litellm.constants import ( @@ -363,15 +365,15 @@ from litellm.proxy.management_endpoints.cache_settings_endpoints import ( from litellm.proxy.management_endpoints.callback_management_endpoints import ( router as callback_management_endpoints_router, ) -from litellm.proxy.management_endpoints.coordination_redis_endpoints import ( - get_persisted_coordination_redis_settings, - router as coordination_redis_settings_router, -) from litellm.proxy.management_endpoints.common_utils import ( _user_has_admin_privileges, _user_has_admin_view, admin_can_invite_user, ) +from litellm.proxy.management_endpoints.coordination_redis_endpoints import ( + get_persisted_coordination_redis_settings, + router as coordination_redis_settings_router, +) from litellm.proxy.management_endpoints.cost_tracking_settings import ( router as cost_tracking_settings_router, ) @@ -14800,7 +14802,16 @@ async def get_config_general_settings( ) -_GENERAL_SETTINGS_UI_LITELLM_FIELDS: dict[str, dict[str, str]] = { +GeneralSettingsUILiteLLMValue = Union[float, bool, str, None] + + +class GeneralSettingsUILiteLLMFieldSpec(TypedDict): + type: Literal["Float", "Boolean", "Select"] + description: str + options: NotRequired[tuple[str, ...]] + + +_GENERAL_SETTINGS_UI_LITELLM_FIELDS: dict[str, GeneralSettingsUILiteLLMFieldSpec] = { "budget_exceeded_throttle_percentage": { "type": "Float", "description": ( @@ -14809,18 +14820,64 @@ _GENERAL_SETTINGS_UI_LITELLM_FIELDS: dict[str, dict[str, str]] = { "over-budget keys." ), }, + "enable_anthropic_prompt_caching": { + "type": "Boolean", + "description": ( + "Automatically add Anthropic cache_control breakpoints to the system prompt and the " + "trailing turn, for Anthropic and Bedrock Claude models that support prompt caching.

Align the docs to the code so the single most important contract reads the same everywhere; a dead proxy turns a run red instead of being silently skipped and mistaken for a pass. The per-suite conftest docstrings that described the shared hook as a "proxy liveness skip" are corrected to "liveness gate" for the same reason. Also scope the no-unit-tests hard rule to what it means: never substitute a unit test for e2e feature coverage, while explicitly allowing tests that cover the harness itself (e.g. coverage_registry/test_collector.py), which carry no e2e marker and run whether or not a proxy is up. No product code and no harness logic changed.

An admin registers an upstream MCP server through the management API (POST /v1/mcp/server, persisted in the DB and picked up without a restart) and queues its deletion. Two keys are created against that one server: one granted access through object_permission.mcp_servers and one with no MCP grant. The permitted key is a live control proving the upstream is reachable and the tool is callable, so a denial on the ungranted key is an authorization decision rather than a dead server. The denied key then sees none of the server's tools on tools/list and is refused a tools/call with a 403 access_denied. A deterministic self-hosted FastMCP upstream (add/multiply over streamable-http) is added to the e2e compose stack so the suite runs offline with a known tool set. KeyGenerateBody gains an optional typed object_permission so the shared gateway can create a key with an MCP grant. --- tests/e2e/CLAUDE.md | 1 + tests/e2e/docker-compose.yml | 24 +++- tests/e2e/mcp/conftest.py | 16 +++ tests/e2e/mcp/mcp_client.py | 153 +++++++++++++++++++++ tests/e2e/mcp/test_mcp_key_access_e2e.py | 103 ++++++++++++++ tests/e2e/models.py | 5 + tests/mcp_tests/mcp_e2e_upstream_server.py | 40 ++++++ 7 files changed, 341 insertions(+), 1 deletion(-) create mode 100644 tests/e2e/mcp/conftest.py create mode 100644 tests/e2e/mcp/mcp_client.py create mode 100644 tests/e2e/mcp/test_mcp_key_access_e2e.py create mode 100644 tests/mcp_tests/mcp_e2e_upstream_server.py diff --git a/tests/e2e/CLAUDE.md b/tests/e2e/CLAUDE.md index 3c3515ba2bd..67e9f4f78a7 100644 --- a/tests/e2e/CLAUDE.md +++ b/tests/e2e/CLAUDE.md @@ -13,6 +13,7 @@ Each subdirectory under `tests/e2e/` is one suite, scoped to an endpoint family - `realtime/` - realtime websocket sessions, including the pipecat audio path - `quota_management/` - quota enforcement and accounting, one subfolder per behavior: `ratelimit/` (rpm/tpm blocks, window reset, pacing headers on live traffic), `budgets/` (budget definition, enforcement, and reset windows: key, team, tag, soft, multi-window), and `spend_tracking/` (spend logging and cost attribution on `/spend/*`) - `management/` - key/team/user/organization management routes: create/update/delete persistence via the info routes, team membership, and llm-only-key route denials; also the dashboard UI behavior on top of them, driven through the proxy-served UI at /ui with playwright (optional dep behind importorskip) +- `mcp/` - the MCP server surface over api_key auth: an admin registers an upstream MCP server through the management API and grants keys access via `object_permission.mcp_servers`, then the suite asserts tool listing and calling honor that permission (a key without the grant sees none of the server's tools and is refused a `tools/call` with a 403) - `logging/` - logging-integration delivery (datadog and friends) - `security/` - secret handling and log-leak protection - `router/` - routing and reliability behavior (fallbacks, cooldowns) diff --git a/tests/e2e/docker-compose.yml b/tests/e2e/docker-compose.yml index a117cbd570d..29d54b011be 100644 --- a/tests/e2e/docker-compose.yml +++ b/tests/e2e/docker-compose.yml @@ -1,5 +1,7 @@ # local setup to run e2e tests configs: + mcp_upstream_server: + file: ../mcp_tests/mcp_e2e_upstream_server.py litellm_config: content: | general_settings: @@ -131,7 +133,27 @@ services: target: /app/config.yaml command: ["--config", "/app/config.yaml", "--port", "4000"] -# throwaway db +# deterministic self-hosted upstream MCP server (FastMCP add/multiply over +# streamable-http), reachable by the litellm container at mcp-upstream:8090/mcp. +# Not a depends_on of litellm on purpose: only the mcp suite needs it, and it +# boots long before the proxy is live, so it must not gate the other suites' +# stack.

Any OpenAI-compatible client talking to a litellm proxy with vertex embedding models got a 400 unless the operator set proxy-wide drop_params: true. Float lists are exactly what the vertex API returns, so the param is a no-op: pop it before validation. Other values (e.g. 'base64') keep the existing unsupported-param behavior (dropped with drop_params, raise otherwise).

Opik's backend validates the embedded UUIDv7 timestamp on ingestion (OPIK-7067); the bad encoding decoded to ~year 2201 and every trace/span batch was rejected with HTTP 400. Rewrite create_uuid7() to be RFC 9562 conformant (top 48 bits = unix-ms), using the standard library only so no new dependency is added.

Uvicorn counts both active tasks and accepted connections and returns HTTP 503 once the configured limit is reached. Reject non-positive limits at CLI parse time and only add the setting to the uvicorn startup arguments. Because idle connections also consume capacity, deployments should use upstream connection/header timeouts and per-client connection limits. * test: reorder test_utils tail to keep the daily merge conflict-free (#33788) The daily OSS branch and litellm_internal_staging each appended an independent test block at the very end of tests/test_litellm/test_utils.py, so merging the two collides on that shared end-of-file position even though the additions are unrelated (this branch adds the vertex embedding encoding-format tests; staging adds the per-model prompt-cache-minimum tests). Moving this branch's new TestVertexEmbeddingEncodingFormat class above test_gemini_image_models_do_not_support_reasoning, which both branches share, gives the two additions different anchors, so git applies both without a conflict and without pulling staging into this branch. Pure reorder; no test bodies change --------- Co-authored-by: Mateo Wang <277851410+mateo-berri@users.noreply.github.com> Co-authored-by: devin-ai-integration[bot] <158243242+devin-ai-integration[bot]@users.noreply.github.com> Co-authored-by: Mihidum Hettiyahandi <55163074+mihidumh@users.noreply.github.com> Co-authored-by: madan-singulr <150280287+madan-singulr@users.noreply.github.com> Co-authored-by: greptile-apps[bot] <165735046+greptile-apps[bot]@users.noreply.github.com> Co-authored-by: aniket-kardile Co-authored-by: veria-ai[bot] <224490171+veria-ai[bot]@users.noreply.github.com> Co-authored-by: Aliaksandr Kuzmik <98702584+alexkuzmik@users.noreply.github.com> Co-authored-by: Claude Opus 4.8 (1M context) Co-authored-by: Salva Madrid <50212436+salvamadrid@users.noreply.github.com> --- litellm/integrations/opik/utils.py | 50 +- .../guardrail_hooks/singulr/__init__.py | 50 ++ .../guardrail_hooks/singulr/singulr.py | 216 +++++++ litellm/proxy/proxy_cli.py | 16 + litellm/types/guardrails.py | 5 + .../guardrails/guardrail_hooks/singulr.py | 63 ++ litellm/utils.py | 6 + .../integrations/test_opik_utils.py | 29 + .../guardrail_hooks/test_singulr.py | 550 ++++++++++++++++++ tests/test_litellm/proxy/test_proxy_cli.py | 73 +++ tests/test_litellm/test_utils.py | 49 ++ 11 files changed, 1081 insertions(+), 26 deletions(-) create mode 100644 litellm/proxy/guardrails/guardrail_hooks/singulr/__init__.py create mode 100644 litellm/proxy/guardrails/guardrail_hooks/singulr/singulr.py create mode 100644 litellm/types/proxy/guardrails/guardrail_hooks/singulr.py create mode 100644 tests/test_litellm/integrations/test_opik_utils.py create mode 100644 tests/test_litellm/proxy/guardrails/guardrail_hooks/test_singulr.py diff --git a/litellm/integrations/opik/utils.py b/litellm/integrations/opik/utils.py index 7222c9d0502..d4850d50778 100644 --- a/litellm/integrations/opik/utils.py +++ b/litellm/integrations/opik/utils.py @@ -1,40 +1,38 @@ import configparser import os import time +import uuid from typing import Any, Dict, Final, List, Optional, Tuple CONFIG_FILE_PATH_DEFAULT: Final[str] = "~/.opik.config" -def create_uuid7(): - ns = time.time_ns() - last = [0, 0, 0, 0] +def create_uuid7() -> str: + """Generate an RFC 9562 conformant UUIDv7 string. - # Simple uuid7 implementation - sixteen_secs = 16_000_000_000 - t1, rest1 = divmod(ns, sixteen_secs) - t2, rest2 = divmod(rest1 << 16, sixteen_secs) - t3, _ = divmod(rest2 << 12, sixteen_secs) - t3 |= 7 << 12 # Put uuid version in top 4 bits, which are 0 in t3 + The top 48 bits encode the Unix timestamp in milliseconds.

This raises pyo3 and pyo3-async-runtimes to 0.29 (currently the newest line, and the range starting at 0.26 that supports 3.14) and migrates the three call sites whose APIs were renamed across that range: Python::with_gil is now Python::attach and Python::allow_threads is now Python::detach. On a GIL-enabled interpreter those are pure renames with identical semantics, so behavior on 3.10 through 3.13 is unchanged Verified by compiling the native module for cp313 and cp314 and driving it directly on both interpreters: gil_stats reports exactly one GIL release per sync OCR call and the async path completes, matching the 0.23.5 baseline. cargo fmt, clippy, and the workspace tests pass on both 3.13 and 3.14 with the lockfile locked, and the lock churn is confined to the pyo3 crates Part of #26343; addresses the pyo3 build failure reported in #33116 --- litellm-rust/Cargo.lock | 94 ++++--------------- litellm-rust/Cargo.toml | 4 +- .../crates/ai-gateway/src/python/config.rs | 2 +- litellm-rust/crates/python-bridge/src/gil.rs | 4 +- litellm-rust/crates/python-bridge/src/lib.rs | 2 +- 5 files changed, 22 insertions(+), 84 deletions(-) diff --git a/litellm-rust/Cargo.lock b/litellm-rust/Cargo.lock index 9bffe9f9ec6..f563c18ea14 100644 --- a/litellm-rust/Cargo.lock +++ b/litellm-rust/Cargo.lock @@ -19,12 +19,6 @@ version = "1.1.2" source = "registry+https://github.com/rust-lang/crates.io-index" checksum = "1505bd5d3d116872e7271a6d4e16d81d0c8570876c8de68093a09ac269d8aac0" -[[package]] -name = "autocfg" -version = "1.5.1" -source = "registry+https://github.com/rust-lang/crates.io-index" -checksum = "f2032f911046de80f0a198e0901378627c33f59ea0ac00e363d481118bd70a53" -

The exception was swallowed to a warning while /register still returned 200, so the minted client was never stored and every access-token expiry forced a full re-authorization Persist the acquired DCR client (client_id, client_secret, token_endpoint_auth_method, redirect_uris, encrypted at rest) in a dedicated LiteLLM_MCPServerOAuthClient store keyed by server_id when the server has no row, overlay it onto the in-memory config server so the refresh_token grant can authenticate within the process, and rehydrate it when the registry syncs from the database (which runs after the DB connects, unlike config load) so restarts and other pods pick it up. The store is encrypted at rest and is re-encrypted by the master-key rotation path alongside the server rows, through a shared helper so the two sites cannot diverge. The DB-backed server path is unchanged, and guarding the None return removes the swallowed-crash footgun Resolves the config.yaml DCR persistence regression introduced in v1.92.0 by #31912 --- .../migration.sql | 9 + .../litellm_proxy_extras/schema.prisma | 7 + litellm/proxy/_experimental/mcp_server/db.py | 82 +++- .../mcp_server/discoverable_endpoints.py | 144 +++++-- .../mcp_server/mcp_server_manager.py | 34 ++ litellm/proxy/schema.prisma | 7 + litellm/repositories/table_repositories.py | 4 + schema.prisma | 7 + .../mcp_server/test_db_credentials.py | 64 +++ .../mcp_server/test_discoverable_endpoints.py | 370 ++++++++++++++++++ .../mcp_server/test_mcp_sigv4_auth.py | 2 + 11 files changed, 679 insertions(+), 51 deletions(-) create mode 100644 litellm-proxy-extras/litellm_proxy_extras/migrations/20260717000000_add_mcp_server_oauth_client_table/migration.sql diff --git a/litellm-proxy-extras/litellm_proxy_extras/migrations/20260717000000_add_mcp_server_oauth_client_table/migration.sql b/litellm-proxy-extras/litellm_proxy_extras/migrations/20260717000000_add_mcp_server_oauth_client_table/migration.sql new file mode 100644 index 00000000000..7aa6cdb1e33 --- /dev/null +++ b/litellm-proxy-extras/litellm_proxy_extras/migrations/20260717000000_add_mcp_server_oauth_client_table/migration.sql @@ -0,0 +1,9 @@ +-- CreateTable +CREATE TABLE IF NOT EXISTS "LiteLLM_MCPServerOAuthClient" ( + "server_id" TEXT NOT NULL, + "credentials" JSONB, + "created_at" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, + "updated_at" TIMESTAMP(3) NOT NULL DEFAULT CURRENT_TIMESTAMP, + + CONSTRAINT "LiteLLM_MCPServerOAuthClient_pkey" PRIMARY KEY ("server_id") +); diff --git a/litellm-proxy-extras/litellm_proxy_extras/schema.prisma b/litellm-proxy-extras/litellm_proxy_extras/schema.prisma index f842bf13da9..a99cec49417 100644 --- a/litellm-proxy-extras/litellm_proxy_extras/schema.prisma +++ b/litellm-proxy-extras/litellm_proxy_extras/schema.prisma @@ -396,6 +396,13 @@ model LiteLLM_MCPUserEnvVars { @@index([server_id]) } +model LiteLLM_MCPServerOAuthClient { + server_id String @id + credentials Json? + created_at DateTime @default(now()) @map("created_at") + updated_at DateTime @default(now()) @updatedAt @map("updated_at") +} + // Generate Tokens for Proxy model LiteLLM_VerificationToken { token String @id diff --git a/litellm/proxy/_experimental/mcp_server/db.py b/litellm/proxy/_experimental/mcp_server/db.py index d55eb3ac014..7129582ff2a 100644 --- a/litellm/proxy/_experimental/mcp_server/db.py +++ b/litellm/proxy/_experimental/mcp_server/db.py @@ -33,6 +33,7 @@ from litellm.proxy.common_utils.encrypt_decrypt_utils import ( from litellm.proxy.utils import PrismaClient from litellm.repositories.object_permission_repository import ObjectPermissionRepository from litellm.repositories.table_repositories import ( + MCPServerOAuthClientRepository, MCPServerRepository, MCPUserCredentialsRepository, ) @@ -639,6 +640,7 @@ async def delete_mcp_server( for model, label in ( (prisma_client.db.litellm_mcpusercredentials, "credential"), (prisma_client.db.litellm_mcpuserenvvars, "env var"), + (prisma_client.db.litellm_mcpserveroauthclient, "OAuth client"), ): try: await model.delete_many(where={"server_id": server_id}) @@ -823,26 +825,66 @@ async def update_mcp_server( return updated_mcp_server -async def rotate_mcp_server_credentials_master_key(prisma_client: PrismaClient, touched_by: str, new_master_key: str): +async def get_mcp_server_oauth_client_credentials(prisma_client: PrismaClient, server_id: str) -> object | None: + """Read the persisted (encrypted) DCR OAuth client blob for a server from the + server-scoped store, or None.

dbb5b813c1e70329ea977ceec59831cba4ef4522 Mon Sep 17 00:00:00 2001 From: ryan-crabbe-berri Date: Fri, 17 Jul 2026 20:02:22 -0700 Subject: [PATCH 83/90] test(e2e): budget reset diagonal for team, org, user, and #32005 team-member keys (#33771) * test(e2e): budget reset diagonal for team, org, user, and #32005 team-member keys Adds E2E-7/8/10/11 from the budget-level x key-kind coverage matrix: each budget level serves traffic again after its budget_duration window elapses, walking the same ladder as the enforcement diagonal. New registry rows and tests cover the team, organization, and internal-user reset rungs, plus the #32005 interplay where a team-member key frozen by its owner's user budget comes back when the user's window renews; the bare-key and per-team-member rungs already had coverage Each case isolates the cap to one entity, drives spend to a budget_exceeded block, then polls past the window until a call succeeds, holding every refusal as a budget block so a reset that no-ops (stays blocked forever) or crashes (leaks a 5xx) fails the test. budget_duration becomes an optional param on the budget_client create_team / create_user / create_org helpers * test(e2e): fold the reset diagonal into test_budget_reset_e2e.py and address greptile nits Move the team / org / user / #32005 reset cases out of the standalone test_budget_reset_diagonal_e2e.py and into test_budget_reset_e2e.py, absorbing the pre-existing bare-key reset into the same TestBudgetResetDiagonal spec class so the whole reset ladder reads as one file (mirroring how the enforcement diagonal lives in test_budget_enforcement_e2e.py) and the drive/poll helpers are defined once instead of duplicated across reset files. Greptile nits: bound the drive phase to under one window (12 attempts x 2s < 30s) so a block is observed before the reset job can fire, and replace the bare assert in the poll loop with a pytest.fail that prints the HTTP status, so a provider 429 or a crashed reset path is distinguishable from a budget block at a glance. * test(e2e): trim reset diagonal docstrings back to the file's original style * test(e2e): inline single-use drive-loop bounds * test(e2e): cut the reset module docstring to one line * test(e2e): make the org reset test wait for a scheduled window (bugbot) /organization/new stores budget_duration without scheduling budget_reset_at, so the reset job's NULL catch-up branch zeroes org spend on its first 5-10s tick; the org reset test could pass off that catch-up instead of a real window roll (tracked as LIT-4570). The test now reads the org's budget_id and polls /budget/info until budget_reset_at is scheduled before driving spend, so the recovery it observes can only come from a genuine window expiry. Verified live: the org case now runs ~33s (a full window) instead of beating the rescheduler --- .../coverage_registry/quota_management.yaml | 3 + .../quota_management/budgets/budget_client.py | 41 +++++- .../budgets/test_budget_reset_e2e.py | 127 +++++++++++++----- 3 files changed, 132 insertions(+), 39 deletions(-) diff --git a/tests/e2e/coverage_registry/quota_management.yaml b/tests/e2e/coverage_registry/quota_management.yaml index 0d61f48703d..633351ca97c 100644 --- a/tests/e2e/coverage_registry/quota_management.yaml +++ b/tests/e2e/coverage_registry/quota_management.yaml @@ -18,6 +18,9 @@ - {id: quota_management.budget.model_max.isolates_per_model, module: quota_management, tier: P1, behavior: budget, variant: model_max, assertions: [isolates_per_model], exercised_on: [chat_completions], source: "proxy/hooks/model_max_budget_limiter.py", rationale: "model_max_budget caps one model without touching a sibling's budget"} - {id: quota_management.budget.soft.alerts_without_blocking, module: quota_management, tier: P1, behavior: budget, variant: soft, assertions: [alerts_without_blocking], exercised_on: [chat_completions], source: "proxy/auth/auth_checks.py", rationale: "soft_budget alerts but never blocks traffic"} - {id: quota_management.budget.key.resets_after_window, module: quota_management, tier: P1, behavior: budget, variant: key, assertions: [resets_after_window], exercised_on: [chat_completions], source: "proxy/common_utils/reset_budget_job.py", rationale: "budget_duration zeroes key spend after the window;

Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * feat(proxy): surface custom deployment token limits on /v1/models via cheap index lookup Add Router.get_configured_token_limits, an O(1) model-name index lookup that reads a concrete deployment's configured max_input_tokens/max_output_tokens without triggering pattern matching or deep copies. create_model_info_response layers this over the cost map so custom deployments absent from the cost map still surface their limits, and admin-configured limits override cost-map defaults, while wildcard-expanded names stay on the fast path.

From f759c75466f0475362a5016ad4cd03c1ecbbd515 Mon Sep 17 00:00:00 2001 From: yucheng-berri Date: Fri, 17 Jul 2026 20:31:29 -0700 Subject: [PATCH 86/90] feat: add Straiker guardrail integration (#33781) * feat: add Straiker guardrail integration Implements LLM security guardrails via Straiker with prompt and response inspection, multi-mode execution (pre_call, post_call), and configurable blocking or redaction of flagged content across providers, streaming, images, and tool calls. * fix(guardrails): harden straiker source attribution and error-path consistency Use the operator-configured source for Straiker application attribution instead of a caller-supplied agent_id metadata value, so a caller cannot spoof which application a detection is attributed to. Make _fail reuse _block so a post_call error raises ModifyResponseException like a deliberate post_call block rather than GuardrailRaisedException, and type the blocking helper as NoReturn so the type checker enforces that execution never falls through the BLOCKED branch. Serialize the webhook payload once and send it as raw content to avoid re-serializing on the size check and on every retry. * fix(guardrails): read straiker config and metadata from all supported shapes Handle a dict optional_params in _get_config_value so nested guardrail settings loaded from YAML or the DB (timeout, unreachable_fallback, and the rest) are applied instead of silently falling back to defaults; previously only attribute-style access was supported. Build the webhook metadata bag from the merged metadata so client tags stored under litellm_metadata on routes like /v1/messages reach Straiker the same way identity and application fields already do, and widen the internal-key skip prefix to user_api so proxy-injected budget values are not forwarded. * fix(guardrails): fail safe on straiker interventions without redactions Block instead of passing content through when Straiker returns GUARDRAIL_INTERVENED without replacement texts, so a positive intervention verdict can never silently forward the original flagged content. Fix the streamed-request detection to read the request body from proxy_server_request.body, where the proxy stores it, instead of a top-level body key that is never populated; the previous fallback was dead, so a streamed response whose stream flag was not lifted to the top level would have been redacted rather than blocked while buffering replayed the original chunks. * revert(guardrails): restore straiker caller agent_id application attribution Restore the original behavior where a request-scoped agent_id in metadata sets the Straiker application source, falling back to the configured source. This is the integration's intended per-application attribution; litellm already resolves a key-owned agent_id ahead of any caller-supplied value, so a configured key cannot be spoofed. * revert(guardrails): restore straiker webhook metadata scoping Restore the original behavior where the Straiker webhook metadata bag is built from request-scoped metadata only. Forwarding litellm_metadata was a scope change to what the integration sends to Straiker; keep the author's intended scoping. * fix(guardrails): keep proxy key material out of straiker webhook metadata Widen the internal-key skip prefix from user_api_key_ to user_api so the proxy-injected user_api_key hash and user_api_end_user_max_budget are not copied into the Straiker webhook metadata bag. The narrower prefix missed the bare user_api_key name, leaking the hashed key to the vendor. Keeps the request-scoped metadata source unchanged. --------- Co-authored-by: cs-mehta --- .../guardrail_hooks/straiker/__init__.py | 71 ++ .../guardrail_hooks/straiker/straiker.py | 541 +++++++++++++
