Implementing that method also flips the proxy's unified-vs-native dispatch, which would move request traffic off these guardrails' own hooks. Add an opt-out that keeps every lifecycle event on the native hooks, so only the endpoint changes. * test(guardrails): cover the remaining native-hook opt-out dispatch sites Adds regression tests for the parallel post-call path, the MCP post-call hook, and the policy engine step, so every read of the opt-out flag fails when removed. --- litellm/integrations/custom_guardrail.py | 5 +- .../litellm_core_utils/realtime_streaming.py | 2 + litellm/proxy/common_request_processing.py | 12 +- .../guardrail_hooks/azure/prompt_shield.py | 20 +- .../guardrail_hooks/azure/text_moderation.py | 20 +- .../proxy/policy_engine/pipeline_executor.py | 4 +- litellm/proxy/utils.py | 14 +- .../azure/test_azure_prompt_shield.py | 76 +++++ .../azure/test_azure_text_moderation.py | 75 +++++ .../policy_engine/test_pipeline_executor.py | 39 +++ .../test_proxy_logging_hook_detection.py | 289 +++++++++++++++++- tests/test_litellm/proxy/test_proxy_utils.py | 30 ++ 12 files changed, 561 insertions(+), 25 deletions(-) diff --git a/litellm/integrations/custom_guardrail.py b/litellm/integrations/custom_guardrail.py index f721e01e2c8..0172c789d1e 100644 --- a/litellm/integrations/custom_guardrail.py +++ b/litellm/integrations/custom_guardrail.py @@ -102,6 +102,9 @@ class CustomGuardrail(CustomLogger): # If True, during_call runs async_moderation_hook instead of the unified apply_guardrail path. use_native_during_call_hook: ClassVar[bool] = False + # If True, every proxy lifecycle event runs this guardrail's own hooks, not apply_guardrail. + use_native_lifecycle_hooks: ClassVar[bool] = False + records_own_guardrail_information: ClassVar[bool] = False def __init__( @@ -632,7 +635,7 @@ class CustomGuardrail(CustomLogger): return type(self).apply_guardrail is not CustomGuardrail.apply_guardrail def _deployment_pre_call_target(self) -> "CustomLogger": - if not self.uses_apply_guardrail_interface(): + if not self.uses_apply_guardrail_interface() or self.use_native_lifecycle_hooks: return self try: from litellm.proxy.utils import unified_guardrail diff --git a/litellm/litellm_core_utils/realtime_streaming.py b/litellm/litellm_core_utils/realtime_streaming.py index d68bdc4a250..6491362efb3 100644 --- a/litellm/litellm_core_utils/realtime_streaming.py +++ b/litellm/litellm_core_utils/realtime_streaming.py @@ -745,6 +745,8 @@ class RealTimeStreaming: for callback in litellm.callbacks: if not isinstance(callback, CustomGuardrail): continue + if callback.use_native_lifecycle_hooks: + continue if id(callback) in _already_run: continue if not any(callback.should_run_guardrail(data=_check_data, event_type=et) for et in _realtime_event_types): diff --git a/litellm/proxy/common_request_processing.py b/litellm/proxy/common_request_processing.py index 891915eb357..adae59a1174 100644 --- a/litellm/proxy/common_request_processing.py +++ b/litellm/proxy/common_request_processing.py @@ -2669,10 +2669,10 @@ class ProxyBaseLLMRequestProcessing: streaming pipeline (including unified_guardrail end-of-stream blocks) has completed. - Guardrails with apply_guardrail are skipped — they already ran via - unified_guardrail's streaming iterator.

Covers all three Bedrock surfaces: the Converse body requestMetadata field, and a signed X-Amzn-Bedrock-Request-Metadata header on Invoke chat completions and on Invoke /v1/messages, where the header is the only viable leg. The resolver reads both metadata variable names, reserves the whole user_api_key_ prefix against caller-supplied keys, caps the client slot budget explicitly at 16 minus the reserved count, and drops rather than rejects auto-injected values that violate Bedrock constraints. Caller-supplied requestMetadata keeps its existing 400 semantics. The request-metadata field and header are proxy-owned whenever forwarding is enabled. A caller-supplied value, reachable through the generic extra_headers passthrough, is dropped unconditionally and compared case-insensitively, and is replaced only by the proxy's own value, so identity in the AWS billing record cannot be forged. Absence of a resolved value still means absence on the wire rather than a fallback to the caller's. The guardrail headers keep their existing no-displace behaviour. --- litellm/__init__.py | 4 + .../bedrock/chat/converse_transformation.py | 23 +- .../amazon_openai_transformation.py | 11 +- .../base_invoke_transformation.py | 20 +- .../anthropic_claude3_transformation.py | 7 +- litellm/llms/bedrock/request_metadata.py | 199 +++++++++ .../llms/bedrock/test_request_metadata.py | 422 ++++++++++++++++++ 7 files changed, 673 insertions(+), 13 deletions(-) create mode 100644 litellm/llms/bedrock/request_metadata.py create mode 100644 tests/test_litellm/llms/bedrock/test_request_metadata.py diff --git a/litellm/__init__.py b/litellm/__init__.py index 8961de940a0..ae0fee11aeb 100644 --- a/litellm/__init__.py +++ b/litellm/__init__.py @@ -26,6 +26,7 @@ def _dev_env_hot_reload_enabled() -> bool: if os.getenv("LITELLM_MODE", "DEV") == "DEV": _dotenv.load_dotenv(override=_dev_env_hot_reload_enabled()) +from collections.abc import Sequence from typing import ( Any, Callable, @@ -217,6 +218,9 @@ add_user_information_to_llm_headers: Optional[bool] = ( overwrite_user_with_key_hash: bool = ( False # force the outgoing `user` param to the hashed api key, so providers see a stable, tamper-proof id ) +bedrock_request_metadata_fields: Optional[Sequence[str]] = ( + None # allow-list of `user_api_key_*` fields (+ `spend_logs_metadata`) sent as Bedrock `requestMetadata` +) store_audit_logs = False # Enterprise feature, allow users to see audit logs skip_system_message_in_guardrail: bool = False skip_tool_message_in_guardrail: bool = False diff --git a/litellm/llms/bedrock/chat/converse_transformation.py b/litellm/llms/bedrock/chat/converse_transformation.py index 85918d40e12..e4937136108 100644 --- a/litellm/llms/bedrock/chat/converse_transformation.py +++ b/litellm/llms/bedrock/chat/converse_transformation.py @@ -39,6 +39,12 @@ from litellm.llms.anthropic.chat.transformation import ( AnthropicConfig, ) from litellm.llms.base_llm.chat.transformation import BaseConfig, BaseLLMException +from litellm.llms.bedrock.request_metadata import ( + bedrock_request_metadata_headers, + bedrock_request_metadata_is_owned, + merge_bedrock_invoke_headers, + resolve_bedrock_request_metadata, +) from litellm.types.llms.bedrock import * from litellm.types.llms.openai import ( AllMessageValues, @@ -1652,6 +1658,13 @@ class AmazonConverseConfig(BaseConfig): user_continue_message=litellm_params.pop("user_continue_message", None), ) + request_metadata: Final = resolve_bedrock_request_metadata( + litellm_params=litellm_params, caller_metadata=_data.get("requestMetadata") + ) + if bedrock_request_metadata_is_owned(): + _data.pop("requestMetadata", None) + if request_metadata is not None: + _data["requestMetadata"] = request_metadata data: Final[RequestObject] = {"messages": bedrock_messages, **_data} return data @@ -1705,6 +1718,13 @@ class AmazonConverseConfig(BaseConfig): user_continue_message=litellm_params.pop("user_continue_message", None), ) + request_metadata: Final = resolve_bedrock_request_metadata( + litellm_params=litellm_params, caller_metadata=_data.get("requestMetadata") + ) + if bedrock_request_metadata_is_owned(): + _data.pop("requestMetadata", None) + if request_metadata is not None: + _data["requestMetadata"] = request_metadata data: Final[RequestObject] = {"messages": bedrock_messages, **_data} return data @@ -2258,7 +2278,8 @@ class AmazonConverseConfig(BaseConfig): ) -> dict: if api_key: headers["Authorization"] = f"Bearer {api_key}" - return headers + owned_names, metadata_headers = bedrock_request_metadata_headers(litellm_params) + return merge_bedrock_invoke_headers(headers, (), metadata_headers, owned_names) def should_fake_stream( self, diff --git a/litellm/llms/bedrock/chat/invoke_transformations/amazon_openai_transformation.py b/litellm/llms/bedrock/chat/invoke_transformations/amazon_openai_transformation.py index ddbb036df40..1671585be2d 100644 --- a/litellm/llms/bedrock/chat/invoke_transformations/amazon_openai_transformation.py +++ b/litellm/llms/bedrock/chat/invoke_transformations/amazon_openai_transformation.py @@ -13,6 +13,10 @@ import httpx from litellm.llms.bedrock.base_aws_llm import BaseAWSLLM from litellm.llms.bedrock.common_utils import BedrockError +from litellm.llms.bedrock.request_metadata import ( + bedrock_request_metadata_headers, + merge_bedrock_invoke_headers, +) from litellm.llms.openai.chat.gpt_transformation import OpenAIGPTConfig from litellm.passthrough.utils import CommonUtils from litellm.types.llms.openai import AllMessageValues @@ -169,9 +173,12 @@ class AmazonBedrockOpenAIConfig(OpenAIGPTConfig, BaseAWSLLM): """ Validate the environment and return headers. - For Bedrock, we don't need Bearer token auth since we use AWS SigV4. + For Bedrock, we don't need Bearer token auth since we use AWS SigV4.

Cache the bounded set of registered tag names under one aggregate key with the management-object TTL. Uncached request tags are filtered against it before any per-tag DB fetch, so unregistered tags cost zero DB reads on a warm path. An empty registry is cached as a valid answer; DB errors are not cached and fall back to the per-tag lookup; tables past TAG_REGISTRY_MAX_SIZE cache an overflow sentinel that disables filtering. Tag create/update/delete endpoints now evict the registry and per-tag keys and publish cross-worker invalidation (they previously evicted nothing). The per-tag write-back also gains the management TTL it was missing, and the hand-built tag:{name} key strings are replaced with a shared builder. * fix(proxy): skip per-request end-user DB reads via restricted-id registry Every request carrying a user id ran get_end_user_object, and with high-cardinality auto-created end-user rows (hundreds of thousands of ids, all restriction fields NULL) the per-pod cache missed on nearly every request, so each one paid a Postgres find_unique that queued behind the Prisma pool during background-job bursts. True misses were never cached, and unknown ids paid the read twice per request. Cache the bounded set of end-user ids that carry any restriction (blocked, budget, region, default model, or object permission) under one aggregate key with the management-object TTL. When an id misses the per-id cache and is absent from a usable registry, get_end_user_object returns None with zero DB reads; restricted ids keep today's fetch-and-cache path. The skip is bypassed whenever litellm.max_end_user_budget_id is set (default budgets make unrestricted rows behaviorally distinct from missing rows), validate_end_user_id_in_db is on (existence checks need the row), or the token carries end_user_max_budget from custom auth (the row's recorded spend seeds the budget counter). Empty registries cache as a valid answer, DB errors are never cached, and oversized tables cache an overflow sentinel that disables filtering. Customer create/update/block/delete now evict the registry and per-id keys and publish cross-worker invalidation (they previously evicted nothing), and the per-id write-back gains the management TTL it was missing so Redis entries no longer live forever. * refactor(proxy): single generic registry loader with error sentinel and single-flight Code review follow-ups on the two registry caches. Registry DB errors now cache the overflow sentinel for a short REGISTRY_ERROR_NEGATIVE_CACHE_TTL window and log at warning, so a degraded Postgres stops paying the failing registry scan on every request on top of the per-id fallback. Cold registry loads are single-flight per worker behind per-registry locks with a recheck after acquire, so a TTL expiry no longer fans out one full-table scan per in-flight request. The tag and end-user loaders collapse into one _load_bounded_registry with per-entity fetch closures, and the triplicated evict-then-broadcast protocol becomes one evict_and_broadcast helper beside publish_auth_cache_invalidation, shared by the tag, customer, and project eviction paths. * chore(lint): suppress fail-safe registry excepts and ratchet BLE001 budget * docs(proxy): trim registry cache commentary to single-line why docstrings * fix(lint): move tag fetch return to else block to satisfy TRY300 budget --- litellm/constants.py | 7 + litellm/proxy/auth/auth_checks.py | 369 +++++++-- litellm/proxy/auth/user_api_key_auth.py | 2 + .../auth_cache_invalidation_pubsub.py | 22 + .../proxy/common_utils/reset_budget_job.py | 3 +- .../proxy/common_utils/user_api_key_cache.py | 30 + .../customer_endpoints.py | 31 + .../tag_management_endpoints.py | 24 + litellm/proxy/proxy_server.py | 10 +- .../spend_tracking/budget_reservation.py | 5 +- .../proxy/auth/test_auth_checks.py | 750 +++++++++++++++++- .../auth/test_custom_auth_end_user_budget.py | 49 ++ .../proxy/auth/test_user_api_key_auth.py | 135 ++++ .../test_customer_endpoints.py | 127 +++ .../test_tag_management_endpoints.py | 187 ++++- 15 files changed, 1668 insertions(+), 83 deletions(-) diff --git a/litellm/constants.py b/litellm/constants.py index 8f236eba327..75aacd2e6f1 100644 --- a/litellm/constants.py +++ b/litellm/constants.py @@ -1593,6 +1593,13 @@ DEFAULT_MCP_ACCESS_GROUP_NEGATIVE_CACHE_TTL: Final = 10 # in a single ``/{name1,name2,...}/mcp`` URL.
