Google Calendar MCP Server — Hosted Team Tools Integration

mcp-google-calendar — Google Calendar MCP Server

Create, update, and query Google Calendar events through natural language.

Google Calendar is the scheduling backbone for millions of teams and individuals. This MCP server gives your AI agents full access to create, list, update, and delete calendar events — enabling scheduling automation, meeting summaries, and calendar management without opening Google Calendar. The quick_add tool even parses natural language like "Lunch with Bob at noon tomorrow" into a properly structured event.
