Unity MCP Server

What it does

Unity MCP Server transforms AI assistants into a full-scale Unity co-pilot. It provides deep integration with both the Unity Editor and Unity Hub, allowing an AI to manipulate scenes, create GameObjects, manage components, and even run builds and profiling tools without the developer leaving the chat.

Tools

• Scene & GameObject Management: Create, delete, and transform objects; manage the scene hierarchy.
• Unity Hub Control: Install editors, manage modules, and set installation paths.
• Advanced Game Dev: Tools for NavMesh baking, Terrain sculpting, Shader Graph editing, and Physics raycasting.
• Profiling & Debugging: Access to the Frame Debugger, Memory Profiler, and C# compilation errors.
• Multiplayer: Support for MPPM multiplayer playmode scenarios.
