Rename Visibility to Enabled, collapse VisibilityRule into the transform,
and move enabled filtering from Provider to Server level so server-level
transforms can override provider-level disables.
Server authors opt-in by setting list_page_size on FastMCP.
Client convenience methods auto-fetch all pages transparently.
Use _mcp methods with cursor parameter for manual pagination.
- Filter task-eligible components in FastMCPProvider.get_tasks()
- Catch AuthorizationError in get_* methods and return None for consistency
- Remove AggregateProvider from top-level exports
FastMCPProvider now calls _get_* methods instead of get_* to ensure
nested server transforms are applied during lookups. Also converts
string versions to VersionSpec in MCP handlers.
- get_*() now does aggregation + component auth (raises AuthorizationError)
- Deleted _get_*() overrides - inherited from Provider applies transforms
- Simplified AuthMiddleware to global auth only
- Changed version params to VersionSpec | None (not str | None)
- Updated tests to use _get_*() where visibility filtering is expected
Replace _get_all_transforms() with a .transforms property that returns
[*self._transforms, self._visibility]. This cleanly separates user transforms
from visibility filtering while keeping visibility applied last (outermost).
Also:
- AuthMiddleware now uses get_* instead of _get_* for proper component auth
- Remove redundant _is_component_enabled checks (visibility is a transform)
- Delete dead code (get_component method)
- Add versions field to FastMCPMeta
- Replace asserts with NotFoundError in component_service
- Add None checks in auth and tool transform tests
- Add assertions in component_service.py for None returns
- Add type ignore comments for max() with version_sort_key
- Override _get_tool/resource/template/prompt in FastMCP to apply
server transforms over provider aggregation
- Update FastMCPProvider get_* methods to check for None (not
NotFoundError since get_* now returns None)
- Update versioning tests to expect None instead of NotFoundError
when requesting filtered/nonexistent versions
Resolved conflicts to combine Provider inheritance refactor with versioning feature:
- FastMCP now properly inherits from Provider
- get_tool/resource/template/prompt return None instead of raising NotFoundError
- Deduplication uses version_sort_key to keep highest version per name/URI
- _source_* methods eliminated in favor of inherited _* methods
FastMCP now properly inherits from Provider, eliminating ~200 lines of
duplicated _source_* methods. Key changes:
- get_tool/resource/prompt return None instead of raising NotFoundError
- Visibility filter separated from transforms (applied last)
- Nested server middleware runs on both list and execution operations
- Resource auth failure doesn't fall back to templates
- AggregateProvider kept as user-facing utility class
Updates FastMCP's telemetry to align with the new MCP semantic conventions
from open-telemetry/semantic-conventions#2083. This gives us interoperability
with other MCP implementations while keeping fastmcp.* attributes for things
unique to our framework.
Changes:
- Span names now follow `{method} {target}` format (e.g., `tools/call greet`)
- Added `mcp.method.name` and `mcp.resource.uri` attributes
- Renamed `fastmcp.session.id` to standard `mcp.session.id`
- Kept fastmcp.* attributes for server name, component info, provider details

Validates that session_id is captured on both client and server
spans when using HTTP transport, and that they share the same ID.
