Developed authentication and identity features for the jlowin/fastmcp repository, focusing on secure OAuth and OpenID Connect workflows using Python. Migrated Google authentication from a deprecated endpoint to the current /oauth2/v3/userinfo, updating token verification logic to use user IDs and enhancing error handling and scope validation for improved security. Introduced an alias for the OpenID Connect discovery endpoint, enabling consistent access to OAuth server metadata across various deployment paths. Enhanced the OAuthProvider to support path-aware issuers, registered new routes, and expanded test coverage. Work emphasized robust API integration, backend development, and maintainable authentication infrastructure without addressing bug fixes.

Mar 1, 2026March 2026 (2026-03) highlights: Implemented Google Authentication Verification and Token Handling Enhancements in the jlowin/fastmcp repo. Migrated from the deprecated /oauth2/v1/tokeninfo to the current /oauth2/v3/userinfo endpoint, added robust error handling and scope validation, and updated token verification to identify users via 'sub' (user ID) instead of 'aud' (app ID). Delivered through two commits that solidified the Google sign-in workflow and security posture. Key commits: c3f0223bbbb72cfcf5d33ec68c1c3930827e93cb (replace deprecated /oauth2/v1/tokeninfo with /oauth2/v3/userinfo) and 5be249ada302ce10f6e34ad6b3ee00b1a8e07726 (use sub for client_id instead of aud).
