An end-to-end MCP server that bridges Google Workspace services with AI assistants. It integrates Gmail, Drive, Calendar, Docs, Sheets, Slides, Forms, Tasks, and Chat, plus search capabilities, delivering comprehensive control and automation across Workspace. Built on FastMCP for high performance, it features advanced authentication handling, service caching (30-minute TTL), and streamlined development patterns. The server supports both single-user operation and multi-user authentication via OAuth 2.1, with a simplified setup that leverages Google Desktop OAuth clients—no redirect URIs or port configuration required. It offers transport options including Streamable HTTP and SSE for MCP, as well as stdio and HTTP modes for Claude Desktop. Key security features include automatic token refresh, session management, and a transport-aware architecture with a robust CORS proxy. It also supports stateless container-friendly operation and an external OAuth 2.1 provider mode for external auth flows. Claude Desktop integration provides a one-click install path, while the internal credential store and tooling system enable selective service loading and secure credential management. Reverse proxy compatibility is documented for external deployments.
