Google Calendar

Overview

Google Calendar is a Model Context Protocol (MCP) server: MCP server for Google Calendar integration with service account support and domain-wide delegation. In practice that means any MCP-compatible AI assistant can call Google Calendar's tools directly — the model decides when to use them in a conversation or agent run.

It runs locally: the npm package google-calendar-workspace-mcp-server speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need GCAL_SERVICE_ACCOUNT_CLIENT_EMAIL, GCAL_SERVICE_ACCOUNT_PRIVATE_KEY, GCAL_IMPERSONATE_EMAIL. The current release is v0.0.13, published under the MIT license, with source at pulsemcp/mcp-servers on GitHub, where it has earned 80 stars.

Google Calendar is listed under Productivity on mcp.site and works with any MCP client — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed and the rest of the ecosystem — using the install snippets below.
