  "description": "Cal.com ships an official hosted MCP server at https://mcp.cal.com that gives any MCP-compatible agent full control over scheduling workflows. The server exposes 34 tools covering event types (list, create, update), bookings (create, cancel, reschedule), availability queries, schedule management, and attendee handling. Authentication is OAuth 2.1 over Streamable HTTP — the client redirects once for authorization and the server handles token refresh automatically. Cal.com is free to start (Free plan covers personal scheduling), and the MCP is available to all users.",
