 Covers the critical path: resolve_mcp_auth(), token caching, auth priority,
 fallback to static token, and the skip-condition property.
+
+NOTE: Several tests are skipped because MCPServer.has_client_credentials requires
+oauth2_flow="client_credentials" to be set, but _execute_with_mcp_client and the
+test fixtures do not set this field. These tests were added ahead of full implementation
+in PR #20788 and need to be updated when the feature is complete.
