First-party MCP tool catalog

34 named MCP tools · Calendly-hosted MCP server

The complete exact tool list published for Calendly's hosted server at mcp.calendly.com. Reviewed Jul 10, 2026. Calendly hosts the server and does not support self-hosting. Authentication requires OAuth 2.1 Authorization Code with PKCE and dynamic client registration; static client credentials and personal access tokens are unsupported. The server currently issues both scheduling read and write scopes. Booking requires a paid plan, and routing tools require Teams or higher. Booking, cancellation, availability changes, and organization invitations require explicit confirmation.

Read each catalog boundary before enabling them.

Authentication: OAuth 2.1 with dynamic client registration
