name: script-execute
description: Compiles and executes C# code dynamically using Roslyn. The provided code must define a class with a static method to execute.

# Script / Execute

## How to Call

```bash
unity-mcp-cli run-tool script-execute --input '{
  "csharpCode": "string_value",
  "className": "string_value",
  "methodName": "string_value",
  "parameters": "string_value"
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-tool script-execute --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-tool script-execute --input-file - <<'EOF'
> {"param": "value"}
> EOF
> ```

### Troubleshooting

If `unity-mcp-cli` is not found, either install it globally (`npm install -g unity-mcp-cli`) or use `npx unity-mcp-cli` instead.
Read the /unity-initial-setup skill for detailed installation instructions.

## Input

| Name | Type | Required | Description |
|------|------|----------|-------------|
| `csharpCode` | `string` | Yes | C# code that compiles and executes immediately. It won't be stored as a script in the project. It is temporary one shot C# code execution using Roslyn. IMPORTANT: The code must define a class (e.g., 'public class Script') with a static method (e.g., 'public static object Main()'). Do NOT use top-level statements or code outside a class. Top-level statements are not supported and will cause compilation errors. |
| `className` | `string` | No | The name of the class containing the method to execute. |
| `methodName` | `string` | No | The name of the method to execute. It must be a static method in the class provided above. |
| `parameters` | `any` | No | Serialized parameters to pass to the method. If the method does not require parameters, leave this empty. |
