## About

# Ping

Lightweight readiness probe. Returns the input message or 'pong' if omitted.

## Inputs

- `message` (optional) — when present, echoed back verbatim.

## Behavior

No I/O, no Unity API calls — pure echo. Ideal for measuring round-trip latency or confirming the MCP transport is alive before invoking a heavier tool.

## How to Call

```bash
unity-mcp-cli run-system-tool ping --input '{
  "message": "string_value"
}'
```

> For complex input (multi-line strings, code), save the JSON to a file and use:
> ```bash
> unity-mcp-cli run-system-tool ping --input-file args.json
> ```
>
> Or pipe via stdin (recommended):
> ```bash
> unity-mcp-cli run-system-tool ping --input-file -  {"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 |
|------|------|----------|-------------|
| `message` | `string` | No | Optional message to echo back. |
