Claude and ChatGPT
Claude and ChatGPT can manage bookings through CallSlot's MCP server. It is the same client-facing surface as the API: list bookings, check availability, book, reschedule, cancel, and send an On The Fly Link. It cannot change members, billing, API keys, webhooks, or settings. The Connect AI assistants guide has every step, including Claude Code and Cursor.
- On a Pro space, the owner adds the server address https://app.callslot.app/api/mcp to the assistant.
- The assistant opens CallSlot. Sign in, pick the space, and choose what the assistant may do. No API key is needed.
To stop an assistant, the owner opens Settings → Connections and chooses Disconnect under Connected apps.
Claude
- In Claude, open Customize → Connectors and choose Add custom connector. On a Team or Enterprise plan, an owner adds it first from Organization settings → Connectors → Add → Custom → Web.
- Name it CallSlot. Set the MCP server URL to https://app.callslot.app/api/mcp.
- Choose Add, then Connect, and sign in to CallSlot.
- In a chat, open + and turn the CallSlot connector on.
Claude Code signs in too. Add the server with this command, then run /mcp and choose Authenticate. It can also use an API key. The Connect AI assistants guide has both ways.
