Analysis summary

Cal.com MCP Server is an officially published MCP server from Cal.com. Anomity scores its risk at 20 out of 100 (low).

Cal.com's official server exposes scheduling — availability, event types, and bookings — so an agent can find a slot and book it as part of a longer workflow rather than handing the user a link.

Declared capabilities are outbound network access and credential access. Booking is a state-changing action with real-world consequences and a social cost when it goes wrong, which puts it in the category of tools worth keeping behind confirmation. Calendar data is also quietly revealing: attendee lists and meeting titles describe deals, hiring, and incidents to anyone who can read them.
