Setup

This plugin is the Unity-side component of Unity MCP Pro. To use it with AI assistants, you also need the MCP server.

Install this plugin (see above)
Get the MCP server — Available at unity-mcp.abyo.net

Build the MCP server:

cd server && npm install && npm run build

Configure your AI client (or use the built-in Window → Unity MCP Pro → Server Setup):

{
  "mcpServers": {
    "unity-mcp-pro": {
      "command": "node",
      "args": ["/path/to/server/build/index.js"]
    }
  }
}

Open Unity — The plugin auto-connects when the editor starts. Check Window → Unity MCP Pro for connection status.

Architecture

AI Assistant  ←—stdio/MCP—→  Node.js MCP Server  ←—WebSocket—→  Unity Editor Plugin (this repo)

The plugin runs a WebSocket client inside the Unity editor that connects to the MCP server on 127.0.0.1:6605–6609. All tool calls are dispatched through the CommandRouter to domain-specific command handlers.

Multi-Editor Support

Run multiple Unity editors simultaneously on ports 6605-6609. Set the UNITY_MCP_PORT environment variable to target a specific instance.

Running Tests

Open Unity → Window → General → Test Runner
Select EditMode tab
Click Run All

Requirements

Unity 2021.3 LTS or later
Node.js 18+ (for the MCP server)
Any MCP-compatible AI client
