About Google Calendar MCP

Google Calendar MCP is a Model Context Protocol server that connects AI assistants to Google Calendar, enabling natural-language event management, scheduling, and availability checking. You can create, update, delete, and search calendar events, check free/busy slots across multiple calendars, and handle recurring event modifications, all through Claude Desktop, Cursor, and other MCP-compatible clients. The server supports multi-account and multi-calendar operations, meaning you can connect several Google accounts and list events from multiple calendars in a single request. Cross-account conflict detection automatically warns you when a new event overlaps with existing commitments across any connected calendar. Natural language date and time understanding lets you say things like "schedule a meeting next Tuesday at 3pm" without worrying about date formatting or timezone conversion, the server handles automatic timezone detection from your Google Calendar settings. Several community implementations exist, with the most popular (nspady/google-calendar-mcp) providing a TypeScript-based server focused on reliability and feature completeness. Advanced features include intelligent import from images, PDFs, or web links, the AI can extract event details from a conference flyer or meeting invitation and create the calendar entry automatically. Authentication uses OAuth 2.0 with both Desktop app and Web application credentials supported, and credentials are stored securely on your local machine. The server is open source and free to use.
