Call this BEFORE invoking any external MCP tool or API to check if it is working RIGHT NOW. Returns a verdict (healthy | degraded | down | unknown) plus the live success rate from real agent usage in the last hour, typical p50/p95 latency, top current error signatures, and any active breakage. Use it to decide whether to call a tool, choose a fallback, or tune timeouts and retries — it prevents wasted calls and dead-ends on broken tools. Cheap and fast; safe to call routinely before tool use.
