Google Workspace MCP Server

The Google Workspace MCP Server bridges the gap between AI assistants and the full breadth of Google’s productivity suite. By exposing Gmail, Drive, Calendar, Docs, Sheets, Slides, Forms, Tasks, Chat, and Spaces as first‑class MCP resources, it gives developers a single, consistent API surface to orchestrate complex workflows across these services. The server’s architecture is built on FastMCP, ensuring low‑latency interactions and efficient resource handling even when scaling to multiple concurrent users.

A core value proposition is its support for both single‑user and multi‑user OAuth 2.1 authentication. Developers can spin up a private instance that authenticates each user through Google Desktop OAuth clients, eliminating the need for custom redirect URIs or port forwarding. This streamlined flow is especially beneficial for internal tools, where users already have Google accounts and the overhead of setting up a public OAuth client would be unnecessary. The server also caches service objects to reduce API round‑trips, further improving performance for long‑running assistant sessions.

Key capabilities include end‑to‑end email management (compose, send, archive, label), full calendar CRUD with event reminders and attendee handling, file operations across Google Drive—including Office format conversion—and rich document editing (comments, revisions, collaborative formatting). Spreadsheet and presentation manipulation are exposed with fine‑grained cell access, formula evaluation, and slide layout controls. Forms can be created, updated, and queried for responses, while Chat and Spaces integration allows the assistant to participate in conversations or post updates directly. Tasks and To‑Do lists are also available, giving a holistic view of productivity data.

Real‑world use cases span from automated report generation—where an assistant pulls data from Sheets, compiles it into a Docs document, and schedules a meeting via Calendar—to personalized email assistants that draft replies based on prior conversation context. Workflow automation tools can trigger actions across services (e.g., moving a Drive file to a new folder when a Gmail attachment is received). In enterprise settings, the server can be deployed behind a corporate firewall, providing a private cloud instance that respects internal security policies while still enabling AI augmentation of Google Workspace.

What sets this MCP server apart is its breadth and depth: it covers every major Google Workspace product with comprehensive, fine‑grained controls, all while maintaining a developer‑friendly interface. The one‑click Claude installation and 1‑click OAuth configuration lower the barrier to entry, allowing teams to prototype AI‑enhanced productivity tools quickly. For developers building intelligent assistants or custom integrations, the Google Workspace MCP Server delivers a robust, scalable foundation that turns everyday Google services into programmable building blocks.
