Availability: InStock
Author: iceener

What it does

Connects AI assistants to Google Calendar so they can search events across all calendars, create and update events (including via natural language like "Lunch tomorrow at noon"), check free/busy availability, respond to invitations, and auto-generate Google Meet links. It runs as a streamable HTTP MCP server with full OAuth 2.1 PKCE authentication, supporting both local Node/Bun and remote Cloudflare Worker deployments.

Tools

search_events — Search events across all calendars by default, with text search, date ranges, and pagination
create_event — Create events using natural language or structured input; supports Google Meet links, attendees, recurrence
update_event — Update or move existing events with PATCH semantics
delete_event — Remove events from any calendar
check_availability — Check free/busy status across calendars before scheduling
list_calendars — Discover available calendars and their IDs
respond_to_event — Accept, decline, or tentatively accept event invitations
