unity-mcp-server
Python MCP server for Unity MCP — enables AI assistants (Claude, Cursor, VS Code Copilot, Windsurf) to control the Unity Editor via the Model Context Protocol.
Quick Start
1. Install the Unity package
In Unity: Window > Package Manager > + > Add package from git URL:
https://github.com/mzbswh/unity-mcp.git?path=unity-mcp
2. Configure your MCP client
