Connect AI clients to Cal.com scheduling through the Model Context Protocol using the hosted server at mcp.cal.com or a local instance.
The Cal.com MCP server wraps theCal.com API v2in theModel Context Protocol, letting you manage bookings, event types, schedules, and more through natural language in any MCP-compatible client.
The fastest way to get started is to connect your MCP client directly tomcp.cal.com. The hosted server uses Streamable HTTP transport with OAuth 2.1 authentication — your client handles the authorization flow automatically.
Point your MCP client to the hosted server URL:
When you first connect, your client walks you through an OAuth authorization flow where you grant the server access to your Cal.com account. No API key is needed.
macOS: ~/Library/Application Support/Claude/claude_desktop_config.json Windows: %APPDATA%\Claude\claude_desktop_config.json json theme={null} { "mcpServers": { "calcom": { "url": "https://mcp.cal.com/mcp" } } } json theme={null} { "mcpServers": { "calcom": { "url": "https://mcp.cal.com/mcp" } } } If you prefer to run the server locally, you can use stdio transport with an API key. This is useful for development or when you want full control over the server.
- Node.js >= 18
- A Cal.com API key — generate one inSettings → Developer → API Keys
Add the following to your MCP client's configuration:
{ "mcpServers": { "calcom": { "command": "npx", "args": ["@calcom/cal-mcp@latest"], "env": { "CAL_API_KEY": "cal_live_xxxx" } } } }
Replacecal_live_xxxxwith your actual API key.
Never share or commit your API key. If exposed, rotate it immediately in yourCal.com settings.
