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"
}'
