* feat(mcp): add BYOM (Bring Your Own MCPs) submission + admin review workflow
Non-admins can now submit MCP servers for review via POST /v1/mcp/server/register.
Admins get a Submissions tab in the UI to approve or reject pending servers.
Approved servers enter the active runtime; rejected ones stay out with notes.
- DB: add approval_status, submitted_by, submitted_at, reviewed_at, review_notes
to LiteLLM_MCPServerTable with migration
- Backend: new endpoints register, submissions, approve, reject
- reload_servers_from_database now only loads approval_status=active servers
- UI: Submissions tab with stat cards, card list, confirm dialogs; non-admin
"Submit MCP Server" button wired to /register endpoint
- Fix get_mcp_submissions to filter by submitted_at IS NOT NULL (not submitted_by,
which can be null for team-scoped keys without an associated user)
* feat(mcp): rename nav item to Team MCPs + add New badge
* fix(mcp): revert nav label, rename Submissions tab to Team MCPs + New badge
* feat(mcp): add MCP Standards — required fields config + CI-style checks on submissions
Adds a "Standards" tab (admin-only) to MCP Servers where admins define which
server fields are required for a submission to pass. Each submission card in
Team MCPs then shows a green ✓ or red ✗ for each required field, with a
summary "N/M checks" badge in the header — like GitHub CI status rows.
Also adds a `source_url` field (GitHub / Source URL) to the MCP server schema
so non-admins can link to the source repo when submitting a server.
- schema.prisma: add `source_url String?` to LiteLLM_MCPServerTable
- migration: 20260309000001_add_mcp_source_url
- _types.py: source_url on NewMCPServerRequest, UpdateMCPServerRequest, LiteLLM_MCPServerTable
- types.tsx: source_url on MCPServer interface
- create_mcp_server.tsx: GitHub/Source URL form field
- MCPStandardsSettings.tsx: new — toggle which fields are required (stored in general settings as mcp_required_fields)
- mcp_servers.tsx: Standards tab (admin-only)
- MCPSubmissionsTab.tsx: load required fields + CI-style check pills on each card
* refactor(mcp): move submission rules into Team MCPs tab, grouped free-form UI
Folds the Standards tab into Team MCPs. Submission Rules panel now lives at the
top of the Team MCPs tab — collapsible, shows active rules as chips when closed,
expands to a grouped checkbox editor (Documentation / Source / Connection /
Security). Removes the separate Standards tab from the nav.
MCPStandardsSettings.tsx is now constants-only (FIELD_GROUPS, MCP_REQUIRED_FIELD_DEFS,
SETTINGS_KEY) — the UI lives in MCPSubmissionsTab.
* feat(mcp): add mcp_required_fields to ConfigGeneralSettings + config/list endpoint
Registers mcp_required_fields as a proper general_settings field so the UI
can read/write it via /config/list and /config/field/update without the
"Invalid field" error. Also fixes a pre-existing pyright None-check issue
in _sync_ui_settings_to_general_settings.
* ui(mcp): GitHub-style PR checks panel on submission cards
* ui: rename Team MCPs -> Submitted Tools, Team Guardrails -> Submitted Guardrails
* address greptile review feedback (greploop iteration 1)
* fix: inline import, add approval workflow tests, rename Submitted MCPs
* fix(mcp): allow re-approval of rejected MCP server submissions
* fix(mcp): evict rejected servers from runtime; enforce mcp_required_fields on /register
* fix(mcp): sort submissions newest-first; force active status on admin-created servers
* fix(mcp): add missing mock in test, show Approve for rejected, clear submission metadata, drop spurious Content-Type
* fix(mcp/ui): show Reject for active servers; show submit form to non-admins with team-key note
* fix(mcp): conditional reload on reject; view-only admin for submissions; block admin from /register
* fix(mcp): match auth_type required-field validation to UI compliance check (reject 'none')
* fix(mcp): block view-only admin from /register; log settings failure; warn on active server reject
* fix(mcp): allow view-only admin to use /register; add _validate_mcp_required_fields tests
* fix(mcp): validate field names in mcp_required_fields; surface backend error in submit UI
* fix(mcp): fix falsy field check; add field-name validation; add take limit; document server-managed fields; close dialog on error
Resolve conflict in perplexity/responses/transformation.py by keeping
the simplified ~50 line version (PR's goal) instead of main's ~410 line
version. Added supports_native_websocket() -> False from main.
Keep unified _FINISH_REASON_MAP dict approach, discard upstream's
inconsistent _VALID_OPENAI_FINISH_REASONS frozenset that mapped to
values not in the OpenAIChatCompletionFinishReason Literal.
* fix(mcp): add AWS SigV4 auth for Bedrock AgentCore MCP servers
Add aws_sigv4 auth type to MCP client via httpx.Auth subclass that
signs each request with SigV4 using botocore. Enables mcp_servers
config to connect to AgentCore-hosted MCP servers.
* docs(mcp): add AWS SigV4 auth documentation for Bedrock AgentCore
Add dedicated docs page for configuring MCP servers with AWS SigV4
authentication, update MCP overview with aws_sigv4 auth type and
config example, and link from Bedrock AgentCore provider docs.

* fix(mcp): address Greptile review — requires_request_body, full header signing, health check
- Add requires_request_body = True to MCPSigV4Auth so httpx buffers the
request body before calling auth_flow (prevents empty body hash for
streaming requests)
- Pass all request headers to AWSRequest for canonical SigV4 signing
instead of only Content-Type
- Exclude aws_sigv4 from health check skip logic since it has its own
credential fields (not authentication_token)
- Fix docs: mark aws_access_key_id/aws_secret_access_key as optional
(falls back to boto3 credential chain)
- Add test for requires_request_body flag

- Add 'token' to MCPAuth enum for custom token auth format
- Implement token auth in MCP client (_get_auth_headers)
- Add token auth support for OpenAPI-based MCP tools
- Add comprehensive unit tests to existing test_mcp_client.py
- Fixes issue where MCP servers expecting 'Authorization: token <value>' header could not connect
When guardrails return the full data dict (e.g. guardrails_ai), the
guardrail response logged to spend logs and OTEL traces could contain
data["secret_fields"].raw_headers with plaintext Authorization headers.
This adds a pop("secret_fields") in the guardrail logging path,
matching the existing pattern used by Langfuse and Arize integrations.
Tested: Verified fix removes secret_fields/raw_headers/authorization
from both /spend/logs/ui responses and OTEL trace span attributes.
* fix(streaming): map unknown finish_reason values to finish_reason_unspecified
Some LLM providers return non-standard finish_reason values that are not
in the OpenAIChatCompletionFinishReason Literal (e.g. ZhipuAI/GLM returns
'network_error' when a streaming error occurs mid-response).
Previously map_finish_reason() fell through with return finish_reason,
passing the unknown value directly to Choices.__init__() which calls
Pydantic validation. This caused a ValidationError that was caught by
stream_chunk_builder() and re-raised as the misleading:
litellm.APIError: Error building chunks for logging/streaming usage calculation
Fix: after all known provider-specific mappings, check if the value is in
the valid set (stop, length, tool_calls, content_filter, function_call,
guardrail_intervened, eos, finish_reason_unspecified, malformed_function_call).
Any value not in this set is mapped to 'finish_reason_unspecified' instead
of being returned as-is.
This is consistent with how other unknown stop reasons (e.g. Vertex AI's
FINISH_REASON_UNSPECIFIED) are already handled.
* refactor: use get_args(OpenAIChatCompletionFinishReason) for valid set
Per code review feedback: replace the hardcoded _valid_finish_reasons set
with a module-level frozenset derived dynamically from the source-of-truth
Literal type via typing.get_args(). This ensures the valid-reason check
stays in sync automatically when new finish reasons are added to the Literal,
and avoids recreating the set on every streaming chunk call.
* test(map_finish_reason): add unit tests and warning log for unknown finish reasons
- Add TestMapFinishReason class in test_core_helpers.py covering:
- All known OpenAI-native values pass through unchanged (parametrized)
- Provider-specific mappings: Anthropic, Cohere, Vertex AI
- Unknown/provider-specific values map to 'finish_reason_unspecified'
- Regression test for ZhipuAI/GLM-5 'network_error' case
- Add verbose_logger.warning() in map_finish_reason() when an unknown
finish_reason is encountered, so operators can track which providers
return non-standard values
When assistant content is already a list containing thinking blocks
inline (not str/None), SEQUENTIAL MODE was still prepending all
thinking_blocks from provider_specific_fields, causing duplication
and breaking Anthropic's position-dependent signature verification.
Now detects if the content list already has thinking blocks and skips
the extend(thinking_blocks) to preserve the original interleaved order.
Addresses the correctness gap identified by Greptile review where
list-content messages bypass INTERLEAVED MODE.

Gemini 2.0+ natively accepts JSON Schema in tool parameters, including
bare {} (TYPE_UNSPECIFIED), anyOf with null, and lowercase types. The
existing _build_vertex_schema pipeline was coercing {} to {"type": "object"},
breaking JsonValue/Any field semantics (issue #22391).
Add _build_vertex_schema_for_gemini_2() that only resolves $ref (which
Gemini doesn't support in tools) and filters unsupported fields. Use it
for Gemini 2.0+ models, keeping the full transform for Gemini 1.5.
