This MCP server provides a bridge between the Model Context Protocol and the Unity Editor, enabling real-time interaction with Unity projects through AI assistants. It exposes editor state, scene hierarchy, game object information, and project settings to clients over WebSocket, and allows executing C# code directly within the Unity Editor. In addition to code execution, it includes robust filesystem tools for reading, writing, editing, and listing files, confined to the Unity project assets directory for security. The server works in tandem with a Unity plugin (C#) and a Node.js-based MCP server (TypeScript/JavaScript), communicating via JSON over WebSocket to transfer commands and data. Key capabilities include retrieving editor state, obtaining current scene details, inspecting objects, reading and modifying files, and managing logs and errors. It also supports monitoring and controlling the Editor’s play mode, and provides convenient methods to locate assets by type and enumerate project files. This setup is suitable for AI-assisted development, asset creation, script editing, debugging, and automated workflows within Unity.
