Google Calendar MCP Server

The Google Calendar MCP server lets any AI agent — Claude, ChatGPT, Cursor, or Codex — call Google Calendar through AllMCP's single hosted endpoint. Connect once and your agent gets 16 Google Calendar tools across calendars, events, availability. There is nothing to install or keep running: AllMCP hosts the connector, you get one URL and one sign-in.

How to connect an AI agent to Google Calendar

1. Add the AllMCP endpoint https://go.allmcp.co/mcp/ to any MCP client (Claude, ChatGPT, Cursor, Codex). Sign in with Google or GitHub when the browser opens — no card, no passwords.
2. Ask your agent to connect Google Calendar. When your agent first calls a Google Calendar tool, AllMCP opens a browser tab to sign in with Google Calendar — no API key to copy or paste.
3. Your agent can now call all 16 Google Calendar tools directly. The first 20,000 tool calls each month are free; system and discovery calls never count.

Google Calendar connects with OAuth — sign in with Google Calendar when your browser opens, no API key required.
