Connect Cursor to ActiveCampaign
One line gives Cursor your ActiveCampaign account as tools: 10 endpoints, contacts, tags, automations, 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 ActiveCampaign. 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: "Create a contact in ActiveCampaign".
One-click install
The line above carries a placeholder; 0n3.app/install mints a real key named for Cursor and fills it in.
