Cal.com MCP
UpCal.com MCP is Cal.com's official open-source MCP server: 34 tools for bookings, event types, schedules and availability, including getBooking, createBooking, rescheduleBooking and cancelBooking. It runs as a remote Streamable HTTP endpoint (mcp.cal.com/mcp) and locally via `npx @calcom/cal-mcp@latest`. The --all-tools flag unlocks the extended set.
Why this server
- 34 tools, including getBooking, createBooking, rescheduleBooking and cancelBooking
- Runs both as remote Streamable HTTP and as a local stdio server via npx
- The --all-tools flag unlocks the extended set beyond the core booking tools

Usage examples
Prompt: Show all my bookings for tomorrow and move the 3pm meeting to 4pm
Result: The agent fetched the list via getBookings and moved the meeting with rescheduleBooking — no trip to the Cal.com dashboard.
Prompt: Create a new "30-min demo" event type and book a slot for Thursday right away
Result: The agent called getEventTypes to check first, then createBooking created the Thursday booking under the new event type.
