Mcp Server Cal

Overview

Mcp Server Cal is a Model Context Protocol (MCP) server: Cal.com scheduling MCP server: manage bookings, event types, and availability. Because it speaks the Model Context Protocol, AI assistants can use Mcp Server Cal as a set of callable tools instead of you copy-pasting between apps.

It runs locally: the npm package @aiwerk/mcp-server-cal speaks MCP over stdio on your machine. Configuration happens through environment variables — you'll need CAL_API_KEY. The current release is v1.0.6, published under the MIT license, with source at AIWerk/mcp-server-cal on GitHub.

On mcp.site, Mcp Server Cal sits in the Productivity category. Any MCP client can use it — Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed among them — via the install snippets below.
