Unity MCP Server
The Unity MCP Server installs a bridge package inside the Editor so the AI can act on your scene directly: create GameObjects, edit Transforms and component values, write C# scripts into the project, and read Console errors.
The biggest time-saver is debugging — hand it a console error and it can see the full stack trace and the relevant scripts, then trigger a recompile to check the fix. No more bouncing between the Editor and your IDE.
Install / Connect

# See the repo's README for the exact command:
# https://github.com/CoplayDev/unity-mcpFollow the official README; env and args vary per server.
Why use it
Good for: Unity developers, especially solo devs and prototypers — having the AI rough out a scene beats dragging things by hand.
Before connecting: it can modify your project files and scenes directly. **Commit your project to version control first** so you can roll back if the AI gets it wrong.
