What is the Multi MCP server?

Most team communication work still happens through a UI a human drives. Multi MCP server moves it into the conversation instead. Manage multiple Gmail accounts in Claude Desktop — search, send, reply, draft, and organize.

The short version

A Model Context Protocol (MCP) server that lets Claude Desktop manage multiple Gmail accounts simultaneously. Listed on the official Anthropic MCP registry and published on npm.

  • Connect unlimited Gmail accounts — personal, work, side projects
  • Search — any inbox using full Gmail search syntax
  • Read — complete emails with MIME parsing
  • Send — , reply in thread, and create drafts
  • Organize — with labels: add, remove, list, archive
  • Mark as read / unread —

Getting it running

multi-gmail-mcp on npm is all you need. Most clients run it directly, so configuration is a few lines and a restart.

The tools it exposes

The server publishes 1 tool. What each one is for:

  • Organization — The Organization tool exposed by this server

What it needs from you

Configuration is passed through the environment: GOOGLE_CLIENT_ID, GOOGLE_CLIENT_SECRET. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

  • Node.js >= 22.5.0 - A Google Cloud project with the Gmail API enabled - Claude Desktop ---

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Plenty of team communication servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Multi's toolset — Organization — is a fair guide to whether it matches your workflow. It is maintained by gx-55; 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.
