Cal.com
Connect your AI agents to Cal.com through its vendor-hosted MCP server.
Generic MCP server
Cal.com builds and hosts this MCP server. Agent Handler proxies your agent’s calls to it, so you get the same auth, tool access controls, and audit trail you get on a Merge Connector. The tool surface itself comes from Cal.com.
Manage bookings, event types, and availability.
Authentication
Cal.com authenticates over OAuth. Your end user approves access in Cal.com’s own consent screen during Magic Link, and Agent Handler holds the token.
Available tools
Tools on a generic MCP server are defined by Cal.com, not by Merge, so the list changes when Cal.com changes it. Agent Handler discovers the current tools when the connection is made and re-discovers them on each resync, which means your agent always sees what the server actually exposes today.
To see the tools available right now, connect Cal.com in the dashboard and open its Connector page, or read Cal.com’s own MCP documentation.
How this differs from a Merge Connector
Merge Connectors are written and tested by Merge against the vendor’s REST API. Merge owns the tool names, the input schemas, the error messages, and the regression tests, so the surface stays stable and the tool descriptions are tuned for agents.
A generic MCP server is the vendor’s own. You get whatever the vendor ships, on the vendor’s release schedule. Agent Handler still handles credential storage, OAuth, tool policy, and audit logging identically, so the governance story is the same either way.
