Several Unity projects at once

You can open several Unity projects at the same time, each with its own server.

  • The port comes from the project path, in the range 51726–51825. The same project always gets the same port, so client configs stay valid across restarts. If the port is taken, the server moves to the next free one; use the port shown in Window > Unity MCP Server.
  • The client config is written for you — .mcp.json for Claude Code, and Cursor or Claude Desktop through the Setup Wizard.
  • /health names the project. Ask it before you trust a connection:
Terminal window
curl http://127.0.0.1:<PORT>/health

The answer includes the project name and path, process ID, package version, protocol version and transports. If projectPath is not the project you meant, update the client’s URL.

The unity://project/info resource gives the AI itself the same answer.
