Connect Cursor to AWS

One line gives Cursor your AWS account as tools: 5 endpoints, s3, send email, lambda, called with your own connection. No key in the prompt, a receipt for every call, revoke Cursor's access alone any time.

Get the line for CursorConnect AWS first

Three steps

  1. Create a free 0n3 account and connect AWS. Paste a key or sign in; it lands in your vault, encrypted.
  2. Install 0n3 into Cursor. One-click install link, or the mcp.json block.
  3. Ask Cursor: whoami. Then: "List customers in AWS".
One-click install

Install

The line above carries a placeholder; 0n3.app/install mints a real key named for Cursor and fills it in.
