* feat(mcp): hand listed-tool metadata to pre-call hooks with per-caller catalog identity Track the tools each MCP server listed per caller identity so pre_mcp_call and during_mcp_call hooks receive the tool description and input schema the client saw. Servers with no caller-dependent inputs share one slot; user identity, forwarded headers, stdio env, relayed bearers, and server-specific auth get their own. Local registry and OpenAPI paths pass the registered metadata and admin description overrides. The Agent 365 guardrail reads the new fields into its evaluate payload.

Server definition changes also drop the cached upstream OAuth metadata. OpenAPI listings look tools up under the normalized registry prefix with the separator, so an overlapping sibling prefix no longer leaks into the list.

Invalidation now bumps a per-server generation and the fetch only stores when the generation it captured before I/O is unchanged. The MCPJWTSigner-based per-caller discovery classification and the api_key to token key change had no reproduction (the signer only injects on tools/list, and UserAPIKeyAuth hashes api_key in place), so both go back to the merge-base behavior. Integration coverage under tests/integration/mcp: overlapping OpenAPI aliases, a config-declared server name with a space, OAuth metadata refetch after a save, and the in-flight stale-write race Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): keep OAuth metadata generations only while a fetch is in flight Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): count queued OAuth metadata fetchers so invalidation survives lock handoff Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): keep a held OAuth metadata lock registered even when no fetcher slot claims it Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(mcp): prove a peer worker drops stale upstream OAuth metadata after a save elsewhere Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(mcp): return one masked text per scanned string in the selected-guardrail REST test Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): fold the signed caller into the discovery digest instead of a second key hash Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): satisfy type discipline gate on listed-tool identity Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): hand tools/call hooks the exact catalog entry tools/list served get_listed_tool re-applied the admin description override on top of the cached listing, so a guardrail-masked description was restored to its original wording at call time, and the OpenAPI / local-registry call path built its metadata from the registry instead of the guarded caller catalog. Both paths now return the cached entry as served, falling back to the registry only when no listing was recorded Adds tests/integration/mcp/test_mcp_listed_tool_metadata.py (red on the prior head for the two regressions, red on the merge base for the feature, green on this head) Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): key OpenAPI listed-tool entries per caller so tools/call reads its own guarded listing Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(mcp): align listed-tool slot tests with per-caller keying Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): keep oauth2 listing on the minted or signed credential, not the stored BYOK secret The listing helper that keys the per-caller catalog by the stored BYOK credential also handed that credential to the upstream client, which on an oauth2 server short-circuited the client_credentials mint and the MCPJWTSigner gate. Split the two: the catalog identity keeps the stored credential so tools/call finds the caller's slot, while an oauth2 server's tools/list sends only the per-request header, letting the M2M mint or signed JWT proceed as on main Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * test(mcp): oauth2 BYOK listing sends the minted token, not the stored secret, through the real proxy Integration cell for the listing fix: a client_credentials BYOK server with a stored user credential, one tools/list as that user, the peer must see a live minted bearer and one /token mint. Red at the pre-fix tip (zero mints, stored secret upstream), green at the fixed head and at the merge base Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): keep the stored BYOK credential for catalog identity only on tools/list Listing used the resolved stored credential both to key the caller's catalog slot and as the upstream transport header, so REST api_key and bearer_token listings sent the user's secret instead of the server's static token and the MCPJWTSigner gate went quiet. The upstream client and the signer gate now read the caller-supplied mcp_auth_header for every auth type, exactly as before the catalog existed, and the stored credential only names the slot tools/call reads Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): type the listed-tool metadata read from pre-call kwargs for the basedpyright gate Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): hand never-listed tools/call hooks name and arguments only The local-registry call path fell back to the registry entry with the admin description override when no tools/list had been recorded for the caller, so a pre_mcp_call guardrail scanned a description the caller was never served and blocked OpenAPI calls that passed before, and base's own selected-guardrail REST test failed on the two-text redaction. _registered_tool_metadata now returns the listed entry or None, so a tools/call with no prior listing sends name and arguments only as promised, and that REST test double goes back to its base shape * fix(mcp): keep during_mcp_call hooks on name and arguments only call_tool handed the caller's listed entry to the during-hook task as well, so during_mcp_call guardrails scanned the description line and schema leaves of any listed tool after the upstream call had already run, blocking calls that passed before whenever the policy matched the description, returned a fixed-length texts list, or hit the depth guard on a deep schema. The listed entry is only disclosed for pre_mcp_call, so the during task no longer receives it and its request object carries no description or schema, as before * fix(mcp): key the BYOK catalog slot by the client's header, not the stored credential tools/list resolved the stored BYOK credential to pick the caller's catalog slot, which read the credential store before the classified try block. With Postgres down and a cold per-worker cache that made every REST tools/list on an is_byok server fail with tools=[] and no upstream call, and the read seeded the per-worker cache (including a negative entry), so a tools/call on another worker after a store, rotate or revoke on this one kept using the stale value. The slot is now keyed by what the client supplied plus the caller's hashed key, on both sides. _get_tools_from_server and call_tool take a keyword-only catalog_auth_header that defaults to mcp_auth_header as received (the default is the builtin Ellipsis so it survives a module reload). The /mcp fan-out and execute_mcp_tool, which swap the resolved credential into mcp_auth_header, pass the client's value explicitly. What goes upstream is unchanged. _byok_catalog_auth_header is gone. * fix(mcp): drop a listed catalog recorded across a server save _record_listed_tools ran after the awaited upstream fetch, so a PUT /v1/mcp/server that landed mid-fetch had its invalidation undone when the fetch completed: hooks then saw the pre-save description next to the post-save definition until the next listing, instead of name and arguments only. The manager now keeps a per-server listed-tools generation, bumped by _invalidate_server_definition_caches. _get_tools_from_server reads it before the fetch and _record_listed_tools skips the write when it moved; the next listing records normally. * fix(mcp): drop the catalog again once a saved OpenAPI server's registry is rebuilt add_server and update_server publish the saved definition before the OpenAPI registry entries are rebuilt from the spec, so a listing recorded during that fetch held the pre-save entries under the new generation. The generation is bumped a second time after the registry refresh. The during-hook task no longer accepts a listed entry, the one-line wrapper over get_listed_tool is inlined at its two call sites, and the per-server generation map is a plain dict. * fix(mcp): keep discovery and OAuth metadata caches across an OpenAPI spec re-read add_server and update_server ran the full server-definition invalidation a second time after the awaited OpenAPI spec fetch, which also dropped the prompts/resources/templates discovery entries and the OAuth protected-resource metadata filled under the already-published definition, so the next request went upstream again. Only the listed-tool catalog recorded during the fetch holds pre-save entries, so the post-fetch pass now drops just that catalog and bumps its generation via the new _drop_listed_tools helper, which the full invalidation also calls. * fix(mcp): look a called tool up in the listed catalog by its bare name only get_listed_tool stripped the server prefix a second time when the exact name was absent from the caller's listing, so a never-listed upstream tool whose bare name starts with the server prefix resolved to the listed sibling and that sibling's description and input schema reached the pre-call hooks for a call to a different tool. Every caller already passes the once-stripped bare name, so the lookup is now exact. Tests that looked the catalog up by a prefixed name now use the bare name the callers pass; two new tests pin the never-listed sibling case at the manager and at the tools/call path. * fix(mcp): record a listed-tool catalog only for a listing the caller is served _get_tools_from_server now records the catalog into the caller's listed-tools slot only when asked (record_listing=True), which the served listings pass: the /mcp and Responses API tools/list handlers via _get_tools_from_mcp_servers, MCPServerManager.list_tools, and the REST listing via _list_server_tools. Four internal listings stop recording, so a later tools/call hands pre_mcp_call hooks name and arguments only, as on main: - _list_tools_before_first_call, the implicit listing inside tools/call when this worker does not yet expose the tool - fetch_pinnable_tool_catalog, the admin pin snapshot listed without the catalog guard and without description overrides - _initialize_tool_name_to_mcp_server_name_mapping, the startup fill - get_tools_for_server, used by the semantic tool filter _create_prefixed_tools returns to its tool-name mapping job only; the record follows it in _get_tools_from_server. * fix(mcp): opt every listing out of catalog recording unless it is served The aggregate listing and _list_mcp_tools now default to record_listing=False, so a catalog fetched inside a tools/call no longer fills the caller's listed-tools slot. The /mcp/proxy meta-tools (call_tool, search_tools, get_tool_schema) and the tool-search virtual tool stop recording: /mcp/proxy serves only the meta-tools and the search serves only its hits, so a later pre_mcp_call hook was reading a description the caller never listed. The tools/list handler, the Responses MCP handler and the /v1/mcp/tools management listing opt in with record_listing=True, since each serves the catalog to the caller. * fix(mcp): key the listed-tool slot by the caller's admission identity and forwarded bearer The slot a tools/list records for a later tools/call was keyed by (user_id, api_key) only, so every team-only JWT caller shared one slot and one JWT user acting in two teams shared a slot; a tools/call then handed pre_mcp_call hooks a description another caller was served. The slot is now keyed by the hashed key, user, team and organization, plus the admission credential of a caller admitted with neither a key nor a user. The caller bearer split the slot only on client-forwarded-token and token-exchange servers; a legacy delegated oauth2 server (delegate_auth_to_upstream without client credentials) also forwards it upstream and served a different catalog per bearer into one slot. The bearer now splits the slot on every server whose egress forwards it (_consumes_caller_authorization) or exchanges it. * fix(mcp): record only tools served by the bridge Co-Authored-By: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> * fix(mcp): keep bridge tool metadata request-local * refactor(mcp): centralize listed catalog recording guard * fix(mcp): preserve base TPM reservations for listed tool calls * fix(mcp): preserve project token reservations for listed calls * fix(mcp): record served catalogs and preserve call message bytes * test(mcp): align listing expectation with deferred recording * test(mcp): audit listed metadata across callers and bridge lifecycles * test(mcp): preserve guardrail fixture worker affinity * refactor(mcp): expose listed catalog recording API * feat(mcp): pass served_tools through the anthropic messages bridge /v1/messages auto-execution now hands this request's resolved tool definitions to _execute_tool_calls, matching the Responses and chat completions bridges: the pre_mcp_call hook receives the description and input schema the model was shown for that call. Request-local only; the shared listed-tools catalog is untouched. * test(mcp): pin served_tools handoff on the anthropic messages bridge Mirrors the credentials-forwarding test: the request's resolved tool definitions must reach _execute_tool_calls under served_tools so pre_mcp_call hooks judge the call on the description and input schema the model was shown. Fails without the previous commit's one-liner. * style(mcp): sort the local import block ruff flagged * fix(mcp): keep the admin include_disabled_tools view off the listed-tools catalog GET /mcp-rest/tools/list?include_disabled_tools=true is the admin-only configuration view: apply_tool_filters is False, so it serves the full server catalog. Recording that response into the caller's listed-tools slot warmed tools/call metadata no runtime listing ever served, breaking the only-a-served-listing-records invariant (Bugbot). The record is now gated on apply_tool_filters; disabled tools stay unreachable (the call-time allowlist 403 fires before hooks), so the observable fix is the slot no longer warming from a settings view. Verified live: the new test fails on the unfixed head and passes here, and the rest of the listed-tool-metadata suite is unchanged. --------- Co-authored-by: yucheng <yucheng@berri.ai> Co-authored-by: Devin AI <158243242+devin-ai-integration[bot]@users.noreply.github.com> |
