## Install

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

```bash
godot-cli install-extension com.IvanMurzak.Godot.MCP.Terrain3D
```

## When to ask the AI for it

Ask for open-world ground in Godot — set up a Terrain3D and raise or lower height at a location.

Not sure if it's installed? Ask the agent "Do you have Terrain3D tools available?" — the terrain3d- tools only exist when the package is present.

## Example prompts

1. Create a Terrain3D node with a 1024 region size, then raise the terrain to height 20 at the origin.
2. How many regions does the Terrain3D have?
