How to add Square to Cursor

Open Cursor Settings → MCP and add a new server, or edit ~/.cursor/mcp.json (or .cursor/mcp.json in a project).
Paste the remote URL, or the install config from the server page for a local server.
Sign in if the server asks, then use it in Agent chat.

Menus change, so check Cursor's MCP docs. Every server page has a copy-paste config for Cursor.
