} Frequently asked questions
What is the Cal.com MCP server?
It is a Model Context Protocol (MCP) server — a small piece of software that gives AI assistants like Claude a secure, governed connection to Cal.com. Manage Cal.com scheduling by natural language — view bookings, reschedule, check open slots, and edit event types. Hosted or self-hosted with 34 tools.
Is there an official Cal.com MCP server?
Yes. The Cal.com MCP server is an official integration, maintained by the vendor or the Model Context Protocol project, which makes it the safest default for business use. It is maintained by Cal.com.
Is the Cal.com MCP server hosted, or do I run it myself?
Both. Cal.com runs a hosted endpoint at https://mcp.cal.com/mcp, so most people just paste that URL into their AI client. You can also run the server locally with npx, supplying your own credentials.
Do I need an API key for the Cal.com MCP server?
No API key is needed for the hosted server. You sign in through Cal.com's own OAuth screen, and the assistant only gets the access your account has.
What can an AI assistant actually do with Cal.com?
Through this server an assistant can work with bookings, rescheduling, availability, event types — reading from and acting on Cal.com directly instead of you copy-pasting between windows. What you allow it to do is controlled by the permissions you grant.
How do I set this up for my business?
The setup section above has copy-paste config for Claude Code, Claude Desktop, Cursor and VS Code. If you want it rolled out across a team with permissions, governance and support handled, that is what Crox's Build engagement covers.

Want this connected to your business — with governance handled?
Crox maps your processes, connects AI to the tools you already use, and keeps it working as models change. Start with a readiness assessment or talk to us about a build.
