Enables AI assistants to interact with Gmail and Calendar services through a Model Context Protocol (MCP) server.
Gmail MCP server exists for a simple reason — assistants are far more useful when they can act on Gmail directly instead of describing what you should do. Enables AI assistants to interact with Gmail and Calendar services through a Model Context Protocol (MCP) server.
Once Gmail is connected, these are the calls the assistant has available:
Security — The Security tool exposed by this serverPrerequisites — The Prerequisites tool exposed by this serverInstallation — 1. Clone and install dependencies: bash git clone [repository-url] cd gmail-mcp-server npm installYou will need 3 environment variables: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET, GOOGLE_REFRESH_TOKEN. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.
Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client.
Among the team communication options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Gmail's toolset — Security, Prerequisites, Installation — is a fair guide to whether it matches your workflow. It is maintained by zacco16; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
