net_ping · LuzzyTool MCP: Risk & Policy

WHAT IT DOES

What net_ping does on LuzzyTool

AI agents invoke net_ping to trigger actions in LuzzyTool. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why net_ping needs a policy

This tool executes a ping command (a shell/network operation) to check host reachability and latency. It triggers an external network operation whose effects depend on the target argument. While ping is generally benign and read-like in intent, it is an active execution of a system/network command, making Execute the appropriate category.

From the tool's definition 执行 ping 检测 (execute ping detection) — actively runs a network diagnostic command against a host

Verdict

net_ping Rate-limited

net_ping stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
