Connect Cursor to Unity

Add the server to the project’s .cursor/mcp.json:

.cursor/mcp.json

{
  "mcpServers": {
    "nanora-unity-mcp": { "type": "sse", "url": "http://localhost:<PORT>/sse" }
  }
}

The port is shown in Window > Unity MCP Server. The Setup Wizard writes this file for you when it detects Cursor (Configure All Detected Clients).

Turn on Optimize for MCP in the Setup Wizard so Unity keeps answering while Cursor is in front.
