What it does

This server provides a reference implementation for building MCP servers with secure OAuth 2.1 authentication. It acts as an identity layer that allows MCP clients to authenticate users via providers like Google before accessing protected tools and resources.

Tools

authenticate: Initiates the OAuth flow for the current user.
verify_token: Validates an existing access token against the OAuth server.
get_user_profile: Retrieves identity information for the authenticated session.
