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

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:

unity-mcp-cli run-system-tool ping --input-file args.json

Or pipe via stdin (recommended):

unity-mcp-cli run-system-tool ping --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.
