How it works

1

Connect Your Calendar

Click "Connect via Google OAuth" and authorize access. Takes 30 seconds. Google Advanced Protection users can use the service account flow instead.

2

Get Your API Key

After connecting, you land on the dashboard with a unique API key. Copy it. That key is how your agent authenticates.

3

Add to Your Agent

One command or one settings field. Works with Claude.ai, Claude Code, Cursor, and any HTTP MCP client.

What you can build

CalendarMCP powers agent workflows across scheduling, travel, team coordination, and more.

Executive Assistant

Brief me on today, reschedule conflicts, prep meeting context, and find open time across multiple calendars.

Travel Planning

Add flights, hotels, and activities as all-day events. Never miss a check-in or departure.

Team Coordination

Find open slots across multiple calendars, schedule team events, and manage attendees without the back-and-forth.

Scheduling Automation

Let your agent handle the scheduling back-and-forth. Propose times, check availability, book it.
