How to connect Square to Cursor

1. 1. Enable Square in Metorial

   In your Metorial portal, enable the Square MCP server and sign in with the account that owns the data. Access stays governed by your team policies.

2. 2. Add Metorial to your MCP config

   Use ~/.cursor/mcp.json for every project, or .cursor/mcp.json for one.

   Copy

   {
     "mcpServers": {
       "metorial": {
         "url": "<your-magic-mcp-url>"
       }
     }
   }

3. 3. Sign in

   Open Customize in the sidebar, find Metorial and sign in to load Square tools.

• Cursor shows each Square tool response in chat, with expandable views of the arguments and the result.

Metorial connects but tools are missing or failing

Open the Output panel (Cmd+Shift+U), choose MCP Logs, and look for authentication or connection errors.

Your company blocks the server

Enterprise admins approve remote servers in Team Settings, then MCP Configuration. Ask them to add a URL entry for your Metorial URL.

Cursor asks before every tool call

That is the default. Allowlist the Metorial tools you trust in your Run Mode settings to run them without a prompt.

Based on the Cursor MCP documentation.
