Connect Google Calendar without code

Google Calendar's docs confirm it works in Claude. You don't need a terminal or a config file. Check Google Calendar's docs first: some vendors give you a personal URL or an API key to use in place of the plain endpoint.

Claude (web and desktop app)

If Google Calendar shows up when you browse connectors in Claude, connect it from there instead. That skips steps 2 to 4.

In Claude, open Customize → Connectors.
Click + Add, then Add custom connector.
Name it “Google Calendar”, paste the server URL https://calendarmcp.googleapis.com/mcp/v1, and click Continue.
Review the sign-in settings Claude detected and click Add.
Click Connect and sign in to Google Calendar. Then ask Claude something like “What can the Google Calendar connector do?”

On Team and Enterprise plans, an Owner adds the connector first under Organization settings → Connectors → Add → Custom → Web. Each person then connects it from Customize → Connectors. Free plans can add one custom connector.

Steps from the Claude Help Center: support.claude.com, checked 2026-10-16

From Google Calendar's docs: Developer Preview: requires Google Workspace Developer Preview Program membership and a Google Cloud project with the Google Calendar API and Google Calendar MCP API enabled. In Claude.ai/Claude Desktop (Enterprise, Pro, Max or Team plan) add a custom connector with your own OAuth client ID and secret (redirect URI https://claude.ai/api/mcp/auth_callback). Google also documents Antigravity setup.Source: developers.google.com, checked 2026-10-16

Developer setup (Claude Code, Cursor)

Add this to .mcp.json (Claude Code, project root) or ~/.cursor/mcp.json (Cursor). Remove the // comment line if your client requires strict JSON.

{
  "mcpServers": {
    "google-calendar": {
      "url": "https://calendarmcp.googleapis.com/mcp/v1"
    }
  }
}

Add the endpoint to your client config (above), or as a custom connector in Claude.
Complete the OAuth sign-in. In Claude Code, run /mcp and pick the server.
Test it with a prompt like: “List the tools the Google Calendar MCP server exposes.”
