How to connect Attio to ChatGPT
- In ChatGPT, turn on developer mode (Settings → Apps / Connectors → Advanced; on Business, Enterprise and Edu an admin enables it first).
- Add a custom MCP server and paste the server URL from the server page.
- Sign in when asked, then mention the app with @ in a chat.
