Gmail

This connects Claude to Gmail via OAuth, exposing the full Gmail API as MCP tools. You get message and thread operations (list, get, send, forward, modify), draft management, labels, filters, attachments, and vacation responders. The server acts as an OAuth proxy so you don't store tokens yourself. It runs locally over HTTP and handles the Google OAuth dance automatically. Reach for this when you want Claude to handle email workflows like finding receipts for expense reports, tracking packages by digging through shipping notifications, or setting up vacation mode across multiple services. The thread-based tools are generally preferred over individual message operations for better context.
