Fixes breaking changes from mcp-python-sdk PR #982 which updated
BearerAuthBackend to use TokenVerifier protocol instead of OAuth providers.
Changes:
- Add verify_token() method to BearerAuthProvider implementing TokenVerifier protocol
- Add verify_token() method to InMemoryOAuthProvider implementing TokenVerifier protocol
- Update BearerAuthBackend usage in setup_auth_middleware_and_routes() to pass TokenVerifier
- Add comprehensive unit tests for TokenVerifier implementations
- Add integration tests for BearerAuthBackend with TokenVerifier
- Add tests for HTTP auth setup functions
All existing functionality preserved with full backwards compatibility.
