- Move from fastmcp.experimental.sampling.handlers.openai to fastmcp.server.sampling.openai
- Update docs and tests to use new import path
- Remove experimental handlers directory
* Implement MCP background tasks (SEP-1686) using Docket
Adds support for background task execution via the MCP task protocol,
powered by Docket for task queue management.
- Tools, resources, and prompts can be marked with `task=True` to run async
- Progress dependency for tracking task progress
- CurrentDocket and CurrentWorker dependencies for advanced use cases
- Client API with `.call_tool(..., task=True)` returns task handles
- Task status notifications via subscriptions
- CLI worker command for distributed task processing
Configuration via environment:
- FASTMCP_ENABLE_DOCKET=true
- FASTMCP_ENABLE_TASKS=true
- FASTMCP_DOCKET_URL=redis://... (or memory:// for single-process)

* Fix tasks example import (TaskStatusResponse → GetTaskResult)
The example was using a non-existent TaskStatusResponse type.
Updated to use mcp.types.GetTaskResult which is what the
on_status_change callback actually receives.

* Fix env var name in Docket error messages
The error messages referenced FASTMCP_EXPERIMENTAL_ENABLE_DOCKET but the
actual setting is FASTMCP_ENABLE_DOCKET.

- TokenHandler now wraps SDK's handle() to transform `unauthorized_client`
to `invalid_client` on 401 responses per OAuth 2.1 spec
- Update `sample()` return type to use SDK's SamplingMessageContentBlock
- Update test expectations for new SDK fields (`task`, `_meta`)

* Bump ty to >=0.0.1a25 with type fixes
Follow-up to #2295. Updates ty and fixes compatibility issues with alpha 25, including:
- Updated ignore comment syntax (possibly-unbound-attribute → possibly-missing-attribute)
- Fixed async generator type handling with anext()
- Fixed type narrowing for timeout parameters
- Converted base_url assignments to AnyHttpUrl after string manipulation
- Added CallToolResult to return type annotations
- Removed redundant type casts
- Fixed test form data to use strings instead of bytes
ty alpha 25 has limitations with isinstance() narrowing on unions (see pyproject.toml for details), requiring some targeted type ignores.
* Pin ty to ==0.0.1a25
Alpha releases can have breaking changes, so pin to the tested version.
* switch from pre-commit to prek

* Add comprehensive keyring integration tests
Prevents OS keyring pollution during testing by adding a global mock in
conftest.py. Tests verify keyring behavior across platforms and fallback
scenarios without writing to the actual system keyring.
- Add global mock_keyring fixture to tests/conftest.py
- Add TestOAuthProxyKeyring class with 6 keyring-specific tests
- Remove try/except ImportError for keyring (now required dependency)
- Add keyring extra to py-key-value-aio dependency
- Clean up extraneous implementation comments in oauth_proxy.py
* Update OAuth keyring documentation
Update all OAuth-related documentation to reflect keyring-based key management:
- Add version badges to jwt_signing_key, token_encryption_key, and client_storage parameters
- Standardize "Default behavior (`None`):" formatting with backticks
- Ensure consistent messaging about development-only defaults across all docs
- Update oauth-proxy.mdx, oidc-proxy.mdx, http.mdx, storage-backends.mdx, and upgrade-guide.mdx
Changes settings.home from `Path.home() / ".fastmcp"` to use platformdirs.user_data_dir(), following platform conventions (~/Library/Application Support on macOS, ~/.local/share on Linux, %APPDATA% on Windows).
* Use anyio as testing backend
* Remove asyncio markers
* Update streamable http tests
* Replace all subprocess tests
* Replace anyio task groups with asyncio context managers in tests
- Convert run_server_async from anyio task group pattern to asyncio.create_task with async context manager
- Remove task_group fixture from conftest
- Update all test fixtures to use async with run_server_async pattern
- Remove TaskGroup imports from all test files
- Tests now work with pytest-asyncio instead of pytest-anyio
* Update test_github_provider_integration.py
* Upgrade to MCP 1.17+ with RFC 9728 compliance
Updates FastMCP to require MCP 1.17+ and implements RFC 9728-compliant
OAuth protected resource metadata URL handling.
The key change is that .well-known/oauth-protected-resource endpoints
are now registered at path-aware locations. For example, if an MCP
server is mounted at /mcp, the metadata endpoint is now at
/.well-known/oauth-protected-resource/mcp instead of
/.well-known/oauth-protected-resource.
This ensures proper OAuth discovery for path-based resource servers
and aligns with the MCP SDK's implementation of RFC 9728 §3.1.
Changes include:
- Update minimum MCP version from 1.12.4 to 1.17.0
- Use build_resource_metadata_url() for RFC 9728 compliance
- Configure CI to test with latest package versions (--upgrade)
- Update tests for path-aware metadata URLs
- Add icons field to Tool model (introduced in MCP 1.17)
* Fix RemoteAuthProvider integration tests for RFC 9728
* Fix parameterized test for nested base URL paths
