Connect Cursor to ConvertKit
One line gives Cursor your ConvertKit account as tools: 11 endpoints, subscribers, sequences, broadcasts, called with your own connection. No key in the prompt, a receipt for every call, revoke Cursor's access alone any time.
Three steps
- Create a free 0n3 account and connect ConvertKit. Paste a key or sign in; it lands in your vault, encrypted.
- Install 0n3 into Cursor. One-click install link, or the mcp.json block.
- Ask Cursor: whoami. Then: "List subscribers in ConvertKit".
One-click install
The line above carries a placeholder; 0n3.app/install mints a real key named for Cursor and fills it in.
