* feat: add curated MCP server registry for discovery UI
Curated list of 31 well-known MCP servers with names, icons,
categories, transport config, and registry URLs. Includes HTTP
endpoints for GitHub, Atlassian, Sentry, Snowflake, and Cloudflare.
* feat: add GET /v1/mcp/discover endpoint for MCP discovery
Admin-only endpoint that serves the curated MCP registry with
optional query and category filters. Used by the UI discovery modal.
* feat: add DiscoverableMCPServer types for MCP discovery
* feat: add fetchDiscoverableMCPServers network function
* feat: add MCP discovery modal component
Compact list-row layout with category filters, search, and
grouped server list. Follows dev-tool aesthetic.
* feat: wire MCP discovery modal into server management page
Add MCP Server button now opens discovery modal. Card click
pre-fills the create form. Custom Server opens blank form.
* feat: add prefill from discovery and back-to-registry link
Create form accepts prefillData from discovery selection and
shows a Browse MCP Registry link to return to discovery modal.
* test: add unit tests for MCP discovery endpoint and registry
Tests for registry JSON structure validation and endpoint
query/category filtering logic. 15 tests total.
* fix: sync registry with official MCP API and fix stdio prefill

* fix: address Greptile review feedback
- Move `import json` and `import os` to module top level
- Move mcp_registry.json into litellm/proxy/ for pip distribution
- Fix `Text` component: destructure from antd Typography instead of deprecated Tremor
- Update test fixture path to match new registry location

* fix: inject NPM_CONFIG_CACHE into STDIO MCP subprocess env for Docker
npm/npx needs a writable cache directory. In containers the default
(~/.npm) may not exist or be read-only, causing STDIO MCP servers
launched via npx to fail with ENOENT. Inject NPM_CONFIG_CACHE=/tmp/.npm_mcp_cache
into the subprocess env when not already set.
* test: add unit test for NPM_CONFIG_CACHE injection in STDIO MCP
Verifies that NPM_CONFIG_CACHE is auto-injected when not set, and
preserved when explicitly provided. Also moves the import to module
level per code style rules.
* Update litellm/constants.py

* Fix MCP health check CancelledError handling for parallel test execution
Add asyncio.CancelledError handler in health_check_server() and missing
@pytest.mark.asyncio decorator on test_mcp_server_manager_config_integration_with_database.
In Python 3.8+, CancelledError inherits from BaseException, not Exception,
so it bypassed the generic exception handler when pytest-xdist cancels
running tasks after a failure.

* Regenerate poetry.lock to resolve merge conflict markers
The lock file had unresolved conflict markers from a previous merge,
causing poetry to fail with "Invalid statement (at line 8534, column 1)".

- Fix skip condition to detect claude models (was only checking for
"anthropic" in model name, missing "claude-haiku-4-5")
- Add missing skip for OpenAI tests when OPENAI_API_KEY is not set
- Fix TypeError in utils.py when metadata is explicitly None instead
of missing (use `or {}` fallback)
HuggingFace Text Embeddings Inference (TEI) returns embeddings as raw
arrays [[0.1, 0.2, ...]] instead of wrapped format {"embedding": [...]}.
This change handles both formats:
- Raw array: [[...]] (TEI, some HF models)
- Wrapped: {"embedding": [[...]]} (standard HF format)
Fixes SagemakerError: "HF response missing 'embedding' field" when using
TEI containers on SageMaker.

* fix(oldteams.tsx): show policies when creating
* fix(proxy/_types.py): ensure mcp rest endpoints can be called by virtual key
ensures UI works with virtual key testing mcp endpoints
* refactor: migrate get object permissions table logic to happen in user api key auth - allows functions to trust user api key object they receive has what they need
* fix(rest_endpoints.py): filter for allowed tools based on what key has access to
* fix(mcp_server_manager.py): ensure only allowed MCP's are returned to the user, via rest endpoints
* fix:fix: prompt_cache_key OAI + Azure OpenAI
* test_prompt_cache_key_supported
* test_azure_openai_with_prompt_cache_key
* fix: remove unnecessary async from test_azure_openai_with_prompt_cache_key
Addresses Greptile feedback: litellm.completion() is synchronous, so
async def is unnecessary and would silently pass without running.

PermissionDeniedError (403) is defined in litellm/exceptions.py but was
never added to the import block in litellm/__init__.py. This makes it
the only standard HTTP error exception not accessible as
litellm.PermissionDeniedError, forcing users to import from
litellm.exceptions directly.
Fixes#20959
1. Cross-account false match: Added _parse_arn_account_and_role_name()
helper that compares partition + account ID + role name (not just
role name) to prevent same-name-different-account false matches.
2. SSL verify: _is_already_running_as_role() now passes ssl_verify to
the STS client via self._get_ssl_verify(), consistent with all other
boto3 client creation in this module.
3. Overbroad AccessDenied fallback: The catch in _auth_with_aws_role now
only falls back to ambient credentials when _is_already_running_as_role
positively confirms the caller is the target role. Genuine trust-policy
or permission misconfigurations are re-raised.

When aws_role_name is configured but the environment (ECS task role, EC2 instance
profile) is already running as that role, AssumeRole is unnecessary and can fail
with AccessDenied. This adds same-role detection for ECS/EC2 (extending existing
IRSA support) and a fallback to ambient credentials when AssumeRole returns
AccessDenied.

Arize Phoenix and Arize loggers now create dedicated TracerProviders
instead of fighting over the global singleton, and the otel callback
dedup check no longer incorrectly matches Arize subclasses.
