Connect Cursor to Sunday

Before you start

You need a Sunday workspace and the connector address for this agent. The address is HTTPS, and it holds a secret token, so treat it as a password. Sunday is in private beta, and a workspace comes with early access.

The steps

Add this to .cursor/mcp.json in the project, or to ~/.cursor/mcp.json for each project.

{
  "mcpServers": {
    "sunday": { "url": "<address>" }
  }
}

Replace <address> with your connector address.

Do not put a file with the address into version control. The steps follow the docs of Cursor.¹

Check the connection

Ask Cursor to list your pages. It calls list_pages and tells you how many pages it can see.

A first task

Make a Sunday page that explains this module to a new engineer.

What Cursor can do in Sunday

It can list pages, read a page, edit a page, list comments, and reply to a comment. Each edit makes a new version, and the old version stays. You can limit Cursor to one page, and you can set an end time for its access.

Cursor runs on the plan that you already pay for. Sunday sells no AI and no credits.
