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.
Unity-MCP is an open-source C# MCP server that connects AI coding assistants to the Unity Editor via the Model Context Protocol. It enables LLMs to manage assets, edit scenes, modify scripts, and automate tasks inside Unity.

Getting started:
Get from Unity Asset Store or clone repo. Requires Python 3.10+ and Unity Editor. Run MCP client like Claude Desktop, point to localhost server. Docs at coplay.dev. First command: AI says 'create new scene' -- watch it build.
Limitations:
Requires Unity Editor running and MCP client configured -- adds setup time. Limited to MCP-compatible AIs -- skips non-MCP tools like plain ChatGPT. C# focused -- best for Unity's MonoBehaviour scripts, less for shaders.
Cons
- Requires Unity Editor running and MCP client configured -- adds setup time.
- Limited to MCP-compatible AIs -- skips non-MCP tools like plain ChatGPT.
- C# focused -- best for Unity's MonoBehaviour scripts, less for shaders.
- Local-only -- no cloud Unity support or remote collab out of box.
