What is the Cal Dot Com Mcpserver MCP server?

Connect Cal Dot Com Mcpserver to Claude, Cursor or any other MCP client and it stops being a tab you switch to. MCP server for Cal.com Calendar API integration. The cal dot com mcpserver mcp server is what makes that connection.

What the server does

An MCP server implementation that integrates with Cal.com Calendar API, providing appointment scheduling capabilities.

  • Add Appointments — Schedule new calendar appointments with attendee details
  • Update Appointments — Modify existing appointment details such as time and notes
  • Delete Appointments — Cancel and remove existing appointments
  • List Appointments — View scheduled appointments for specific date ranges

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • calcom_add_appointment — Create new calendar appointments
  • Inputs — - eventTypeId (number): The Cal.com event type ID
  • calcom_update_appointment — Update existing calendar appointments
  • calcom_delete_appointment — Delete existing calendar appointments
  • calcom_list_appointments — List calendar appointments in a date range

Credentials and setup notes

Configuration is passed through the environment: CALCOM_API_KEY. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.

Installation

Setup follows the usual MCP pattern — install or clone the server, register it in your client's configuration file, restart the client. The configuration blocks on this page cover the common clients.

Worth knowing first
