Server and credential health (free)
healthCheck MCP server availability with a free liveness call that never spends credits. Confirms server status, reports version, and optionally validates your API token, making it safe for monitoring.
Instructions
Liveness check. FREE — this call never spends credits. Confirms the MCP server is up, reports its version, and (unless you disable it) verifies the credential against a free account endpoint. It never touches a paid data endpoint, so it is safe to call from a monitor.
