Google Calendar MCP Server

An MCP (Model Context Protocol) server for Google Calendar integration using service account authentication with domain-wide delegation. This server enables AI assistants to interact with Google Calendar to list events, create events, manage calendars, and query availability.

People connecting productivity tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

One of 28 MCP servers published from pulsemcp/mcp-servers. Stars and repository activity are shared across all of them. See all 28 →

Claude Code

claude mcp add pulsemcp-mcp-servers-experimental-google -- npx -y google-calendar-workspace-mcp-server

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "pulsemcp-mcp-servers-experimental-google": {
      "command": "npx",
      "args": [
        "-y",
        "google-calendar-workspace-mcp-server"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key

06 · Google Calendar FAQ

What is Google Calendar?

Is Google Calendar still maintained?

Yes - as of 2026-08-25, its last commit was 2026-07-26. We re-verify nightly.

How do I install Google Calendar?

Run `npx -y google-calendar-workspace-mcp-server`. The README documents 4 environment variables (GCAL_SERVICE_ACCOUNT_CLIENT_EMAIL, GCAL_SERVICE_ACCOUNT_PRIVATE_KEY, GCAL_IMPERSONATE_EMAIL…) to set first. Set GCAL_SERVICE_ACCOUNT_CLIENT_EMAIL, GCAL_SERVICE_ACCOUNT_PRIVATE_KEY, GCAL_IMPERSONATE_EMAIL, ENABLED_TOOLGROUPS before connecting. You can also paste the ready-made client config above.

Does Google Calendar run locally?

Yes - it's a stdio server: it runs on your machine (via npx) with your user's permissions. Your data stays local unless the server itself calls external APIs.
