unity-mcp-pro-plugin

Overview

This is a comprehensive MCP server implementation that connects AI assistants to the Unity game editor via a WebSocket-based communication protocol. It supports full Undo/Redo integration with Unity's native system, features production-grade WebSocket with heartbeat and auto-reconnect capabilities, and includes smart type parsing for seamless conversion between string inputs and Unity data types. The architecture clearly separates the Unity plugin from the Node.js MCP server, allowing for reliable domain reload safety and multi-editor support.
