Google Calendar MCP Server
Check your schedule, search events and find open meeting times in Google Calendar.
Officialby GoogleHosted, nothing to installChecked October 18, 2026
Google's hosted Calendar server gives Claude your calendars and events so it can answer questions about meetings, attendees and free time, and suggest slots that work across several calendars. The server also has tools to create, change and delete events, but Claude's directory connector is currently documented as read-only.
Who it is for
- Busy professionals who live in Google Calendar
- Assistants and operations staff who coordinate meetings
- Founders planning their week
Prompts to try
Once it is connected, ask in plain words. Claude decides when to use the server and asks before it changes anything important.

How we checked it
Checked Google's Calendar MCP setup guide (Developer Preview, updated 2026-10-12), Claude's Calendar connector page and the directory listing; the endpoint lists 9 tools and requires Google OAuth for tool calls.
