Your AI can read your email, check your calendar, manage your contacts, and track your tasks — but only if it can talk to Google. GSuite MCP is the bridge. It runs locally as an MCP server and gives any MCP-compatible client access to four Google APIs through 33 tools.

Install

brew install 2389-research/tap/gsuite-mcp

Or build from source:

go build ./cmd/gsuite-mcp

What it does

Gmail — read, search, send, draft, label, trash, and delete messages. CC/BCC supported.

Calendar — list, view, create, update, and delete events.

Contacts — search, browse, create, update, and delete via the People API.

Tasks — manage task lists and individual tasks: create, update, complete, delete.

Beyond the tools, the server ships with prompts for common workflows: triaging your inbox, composing threaded replies, scheduling around your availability, reviewing pending tasks, and looking up contacts. It also exposes live MCP resources — today’s calendar, unread mail, overdue tasks — so your AI has context before you ask.

Multi-account support is built in. Connect your work and personal Google accounts, then tell your AI which one to use:

“Check my work email for anything urgent” “What’s on my personal calendar this week?”

How it works

GSuite MCP runs as a local process. You authenticate once with gsuite-mcp setup, which opens a browser for Google OAuth. Your OAuth tokens stay on your machine in ~/.local/share/gsuite-mcp/. When you run a tool, the server calls the relevant Google API directly and returns the results to your MCP client and its model, so your account data flows between Google, your machine, and whatever model your client uses. It never passes through a server we run, and the server requests only the OAuth scopes it needs.

Add it to Claude Code with one command:

claude mcp add gsuite gsuite-mcp -- mcp

Or drop the config into any MCP-compatible client.

Requirements

Google Cloud project with OAuth credentials (credentials.json)
Gmail, Calendar, People, and Tasks APIs enabled on that project
Go 1.21+ (only if building from source)
