This tool provides a foundational Model Context Protocol (MCP) server designed for deployment on Cloudflare Workers, featuring seamless integration with Google OAuth. It enables developers to establish a secure, remote MCP endpoint where users authenticate via their Google accounts. The project serves as a comprehensive reference for incorporating various OAuth providers into MCP servers using the `workers-oauth-provider` library, managing complex OAuth flows, and leveraging Cloudflare's Durable Objects for persistent state and secure token storage. It's an ideal starting point for building custom AI-powered tools that require user authentication.
