Connect Cursor

1. Open the MCP settings

In Cursor, go to Settings, then Features, then MCP. Choose “Add new MCP server”, or edit ~/.cursor/mcp.json directly for a global connection, or .cursor/mcp.json in your project for a project-only connection.

2. Add the Nucifra server

{
  "mcpServers": {
    "nucifra": {
      "url": "https://mcp.nucifra.com/mcp"
    }
  }
}

3. Sign in

Cursor lists Nucifra as a server with a status dot. Ask the agent to use a Nucifra tool. Cursor opens your browser for sign-in with Google or GitHub, then returns you to the chat with the tool call already finished.

Test it

send this file to nucifra and give me the link

If the server shows a green status dot in MCP settings and the agent returns a link, the connection works.
