* feat: add TokenCache utility and caching to GitHubTokenVerifier
Extract the caching machinery from IntrospectionTokenVerifier into a
shared TokenCache class in fastmcp.utilities.token_cache, then wire
it into both IntrospectionTokenVerifier and GitHubTokenVerifier.
* Remove dead constant, validate negative cache params
* Fix overwrite eviction bug, skip cache on scope lookup failure
* feat: make upstream_client_secret optional in OAuthProxy
Extract _create_upstream_oauth_client() factory method for subclass
override. Cookie signing falls back to JWT key material when no secret.
* fix: include client_id in revocation requests for public clients
* fix: use factory method for revocation auth
* fix: normalize Google scope shorthands and surface valid_scopes
Google accepts shorthand scopes like "email" in authorization requests but
returns full URIs like "https://www.googleapis.com/auth/userinfo.email" in
token responses. The verifier now normalizes shorthands at initialization so
the subset check works regardless of which form was used. GoogleProvider also
now exposes valid_scopes for controlling which scopes clients can request
beyond the required minimum.

* Replace vendored DI with uncalled-for
FastMCP vendored a minimal DI engine extracted from Docket (~164 lines)
with try/except fallback patterns everywhere. The `uncalled-for` package
is a clean, typed extraction of this same system, and since Docket will
also depend on it (chrisguidry/docket#353), `uncalled_for.Dependency`
becomes the single canonical base class.
This deletes the `_vendor/docket_di/` directory, replaces all the
try/except import patterns with direct `uncalled_for` imports, and
updates the `Dependency.execution` → `current_execution` ContextVar
references to match the Docket branch. The `Progress` class now
delegates to an internal impl and returns `self` from `__aenter__`
(matching Docket's pattern) so that ty's generic resolution works
without `type: ignore` suppressions.
Temporarily points pydocket at the `use-uncalled-for` branch so both
sides can be validated together in CI.

* Support Shared() dependencies without docket
Enters a SharedContext at server lifetime so that Shared() dependencies
from uncalled-for resolve once and are cached across tool/resource/prompt
calls. When running with docket, the Worker already handles this; this
covers the non-docket path and direct call_tool() usage.
Also re-exports Shared from fastmcp.dependencies.

* Pair SharedContext __aenter__ with __aexit__ in Context lifecycle
The old `_ensure_shared_context` on the server called `__aenter__()` on a
lazy `SharedContext` but never `__aexit__()`, leaking the exit stack and
its resources. Moved the SharedContext management into Context's own
enter/exit so it's properly paired: when docket is available the lifespan
handles it, otherwise Context creates and cleans up a per-request one.
Updated Shared() tests to use Client (which runs the lifespan) rather
than calling server methods directly, since cross-request sharing
requires a lifespan.

Adds the PropelAuthProvider which delegates to the IntrospectionTokenVerifier
and optionally does an additional resource check.
Adds an example server and client which makes an authenticated request
and gets information from the token.
Updates the documentation (but only for v3 as this isn't in v2).
* Replace type: ignore[attr-defined] with isinstance assertions in tests
* Fix isinstance assertions in failing tests

* Fix Azure provider to handle OIDC scopes correctly
OIDC scopes (openid, profile, email, offline_access) were being
incorrectly prefixed with identifier_uri, causing Azure to reject
authorization requests. This fix:
- Detects OIDC scopes and sends them unprefixed to Azure
- Filters OIDC scopes from token validation (Azure doesn't include
them in access token scp claims)
- Still advertises OIDC scopes to clients via valid_scopes
- Also handles dot-notation scopes (e.g., User.Read) correctly
Fixes#2451, #2420
* Fix dot-notation scopes to be prefixed (custom scopes can have dots)
* Improve Azure scope handling docs with clear examples
* Add Discord OAuth provider and corresponding tests
* Update DiscordProvider client_secret and required_scopes documentation
* Add Discord to authentication support list in README
* Fix Discord token verifier to match actual API response format
Discord's /api/oauth2/@me endpoint returns:
- "scopes" as a list, not "scope" as a space-separated string
- "expires" as ISO timestamp, not "expires_in" as seconds
- "user" data directly in the response (no need for extra API call)
* Simplify Discord token verifier

* Fix Azure scope validation
Azure returns unprefixed scopes in JWT tokens but requires prefixed scopes in authorization requests. The previous implementation incorrectly validated tokens against prefixed scopes, causing "invalid_token" errors.
Simplified AzureProvider to use standard JWTVerifier with unprefixed scopes for validation. Scopes are only prefixed when building the Azure authorization URL via _build_upstream_authorize_url() override.

* Fix Azure scope mismatch causing MCP client validation errors
The AzureProvider was prefixing scopes during authorization but not in
token validation or Protected Resource Metadata, causing MCP clients to
reject tokens with "Server granted unauthorized scopes".
Changes:
- Prefix required_scopes once during __init__ and use consistently
- Pass prefixed scopes to JWTVerifier for token validation
- PRM now advertises prefixed scopes to MCP clients
- Remove unnecessary idempotent prefixing logic in authorize()
- Update comprehensive documentation explaining scope handling
- Update tests to reflect corrected behavior
Closes#2151
* Clarify that identifier_uri is optional in docstring
* Use anyio as testing backend
* Remove asyncio markers
* Update streamable http tests
* Replace all subprocess 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
