## Install

Requires the base plugin com.ivanmurzak.unity.mcp. After installing, reopen the editor so the new tool family appears in the agent's list.

```bash
openupm add com.ivanmurzak.unity.mcp.probuilder
```

## When to ask the AI for it

Ask for blockout / greybox geometry and in-editor mesh editing without leaving Unity.

Not sure if it's installed? Ask the agent "Do you have ProBuilder tools available?" — the probuilder- tools only exist when the package is present.

## Example prompts

1. Create a ProBuilder cube 4×3×4 at the origin and name it `Room`.
2. Extrude the top face of `Room` up by 2 units, then assign the `Concrete` material to it.
