From: Rohan G Date: Thu, 8 Oct 2026 04:20:38 +0530 Subject: [PATCH 02/38] feat(guardrails): extend Akto guardrail to responses, MCP tools, attachments and masking (#44343) * feat(guardrails): extend Akto guardrail to responses, MCP tools, attachments and masking - post_call now waits for Akto and blocks or masks the reply instead of only logging it - pre_mcp_call and post_mcp_call check MCP tool arguments and tool results - attached images, audio and files are sent to Akto's file check - streamed replies are checked every streaming_sampling_rate chunks - context_source routes traffic to Akto's endpoint or agentic policies - tags carry user email, team alias and key alias for attribution * fix(guardrails): harden Akto MCP detection, keep AGENTIC default, block unmappable masking - MCP handling trusts the logger's call type, so request body keys can't skip the prompt check - context_source defaults to AGENTIC, as before - masking that also hits text we can't write back now blocks - move tests to tests/unit and rename attachments.py to akto_attachments.py - regenerate the OpenAPI snapshot and dashboard types * fix(guardrails): ignore a client-sent response in Akto output checks - a "response" field sent in the request body is no longer scanned in place of the model's reply - MCP tool calls in the reply are still checked in that case - split match or-patterns so CodeQL can follow the bound names - cover a masked payload that is not JSON and drop unused test imports * refactor(guardrails): read Akto attachment fields directly instead of pattern captures * fix(guardrails): check Akto attachments in both messages and input * fix(guardrails): check every Akto attachment source and keep more prompt text in scope - check all of a file or image block's sources (file_data, file_url, file_id), since providers pick different ones - send Anthropic search_result blocks to the file check as text - keep document title and context, and legacy functions, in the checked request - take the client IP from the proxy's requester_ip_address before client forwarding headers - read litellm_params identity only from server-side call details * fix(guardrails): never drop an Akto attachment the text check removed - optional metadata (filename, title, format, media type) that isn't a string is ignored instead of failing the block - an attachment block that still can't be read blocks the request - search_result text is checked once, as a file, instead of also in the text check * fix(guardrails): strip only what the Akto file check sends from the text check - the text check keeps every attachment field except the ones the file check sends - document title/context and search_result source/title go to the file check as text, since the /v1/messages text check drops them - accept every image shape LiteLLM forwards (image_url or url, string or object) and check each source - ignore blocks whose type is not a string instead of failing the file check * fix(guardrails): keep model-visible text in the Akto text check - document title/context, text documents and search_result stay in the text check, so no Akto backend skips them - on /v1/messages the text check reads the messages Anthropic receives, with the guardrail's skip/scan scoping applied - a client-sent "response" key can only add reply checks, never skip recording or MCP tool-call checks - a "messages" key on the Responses API can't replace its input in the text check - the recorded IP comes only from the proxy's requester_ip_address * fix(guardrails): keep AktoGuardrail positional args backward compatible * fix(guardrails): keep zero Akto timeouts working and record every stream check A guardrail_timeout of 0 used to fall back to the default; the new ge=1 made the config invalid, so the proxy dropped the guardrail. Zero settings now fall back to the defaults again. The end-of-stream check can be skipped when the last sampled check covered the reply, so mid-stream checks now record, like base. * fix(guardrails): use defaults for non-positive Akto timeouts and sampling rate A zero or negative guardrail_timeout, file_guardrail_timeout or streaming_sampling_rate used to reach the HTTP call or the stream cadence.

The chat stream wrapper wrapped it a second time, and the router unwraps one layer, so the client saw the inner sentinel (message prefixed litellm.MidStreamFallbackError, type null) instead of the provider's RateLimitError. The chat wrapper now re-raises an already wrapped error untouched. * test(streaming): type the bridged stream regression test's locals * fix(streaming): rebuild a bridged mid-stream error with the outer wrapper's bookkeeping * test(integration): cover the bridged stream error typing on every surface Checked-in audit cells for the Responses bridge: chat completions through the OpenAI SDK and httpx, /v1/messages through httpx and the Anthropic SDK, native /v1/responses, the litellm and Router SDK stream paths, and a chaos file with a mixed burst, a worker SIGKILL and a proxy SIGTERM against an owned two-worker proxy. Every cell scripts the provider through a wire server and asserts the caller's body, the upstream's received requests and the spend row by id. * test(integration): read bridged chat content through one helper * test(integration): build the bridged fallback config without mutating the loaded yaml --------- Co-authored-by: mateo-berri <277851410+mateo-berri@users.noreply.github.com> --- .../litellm_core_utils/streaming_handler.py | 20 + .../integration/_support/responses_stream.py | 128 +++++ ...test_responses_bridge_stream_errors_sdk.py | 137 ++++++ .../test_responses_bridge_stream_chaos.py | 368 ++++++++++++++ .../test_responses_bridge_stream_errors.py | 460 ++++++++++++++++++ .../test_streaming_handler.py | 44 +- 6 files changed, 1156 insertions(+), 1 deletion(-) create mode 100644 tests/integration/_support/responses_stream.py create mode 100644 tests/integration/sdk/test_responses_bridge_stream_errors_sdk.py create mode 100644 tests/integration/streaming/test_responses_bridge_stream_chaos.py create mode 100644 tests/integration/streaming/test_responses_bridge_stream_errors.py diff --git a/litellm/litellm_core_utils/streaming_handler.py b/litellm/litellm_core_utils/streaming_handler.py index 43611eb3192..a78e6f17cc9 100644 --- a/litellm/litellm_core_utils/streaming_handler.py +++ b/litellm/litellm_core_utils/streaming_handler.py @@ -2303,9 +2303,29 @@ class CustomStreamWrapper: 429 (rate-limit) is explicitly exempted from the 4xx filter because it is transient and the Router should switch to another model group. + + An error an inner stream already wrapped (the chat-to-Responses bridge + consumes a Responses stream) is rebuilt around the provider exception + with this wrapper's own bookkeeping, so the Router's one-level unwrap + surfaces the provider exception and is_pre_first_chunk says whether + this wrapper's consumer received anything (the inner stream counts a + lifecycle event the bridge never forwards as its first chunk).

schema builds across threads (#45034) A deferred LiteLLM model whose first use happens on two threads at once could lose its freshly built validator to the second thread's rebuild, so GenericLiteLLMParams.model_validate handed back a CredentialLiteLLMParams and the request failed 400 on use_litellm_proxy. LiteLLMBaseModel.model_rebuild now runs under one process-wide re-entrant lock, so a thread arriving mid-build waits for the finished validator instead of rebuilding over it Co-authored-by:
