## Install

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

## When to ask the AI for it

Ask for paths, rails, patrol routes, or anything that follows a curve.

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

## Example prompts

1. Create a closed-loop spline with 6 knots forming a rough circle of radius 5 around the origin.
2. Add a knot to the `Track` spline halfway along it and smooth its tangents.
