unity-mcp and unity-mcp-plugin
These are competing implementations of the same MCP-to-Unity bridge concept, both enabling AI assistants to control Unity Editor through the Model Context Protocol, with the first being more established (6,920 stars) while the second offers a broader tool set (268 tools) as a UPM package.
About unity-mcp
CoplayDev/unity-mcp
Unity MCP acts as a bridge, allowing AI assistants (like Claude, Cursor) to interact directly with your Unity Editor via a local MCP (Model Context Protocol) Client. Give your LLM tools to manage assets, control scenes, edit scripts, and automate tasks within Unity.
This project lets you control your Unity Editor using plain language commands through AI assistants like Claude or Cursor. You can tell your AI to manage game assets, manipulate scenes, modify scripts, and automate various tasks within Unity. It's designed for game developers, 3D artists, and Unity creators who want to streamline their workflow with AI assistance.
About unity-mcp-plugin
AnkleBreaker-Studio/unity-mcp-plugin
Unity MCP Plugin (UPM) — Editor bridge for AI-assisted game development. Enables Claude, Cursor & MCP-compatible AI to control Unity Editor with 268 tools: scenes, GameObjects, components, builds, profiling, Shader Graph, Amplify Shader Editor, terrain, physics, NavMesh & more. Free & open source.
This tool helps game developers accelerate their workflow by allowing AI assistants like Claude to directly control the Unity Editor. It takes commands from your AI assistant, translates them, and executes them within Unity, enabling the AI to create scenes, build levels, manage assets, and even write C# scripts. This is ideal for Unity game developers, technical artists, or level designers who want to leverage AI for rapid prototyping and content generation.
