WHAT IT DOES

What wake_on_lan does on Mcp Nettools

AI agents invoke wake_on_lan to trigger actions in Mcp Nettools. 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.

RISK

Why wake_on_lan is rated High

This tool triggers an external operation (sending a network packet) that causes a remote machine to power on. It is not merely reading data, nor is it destructive or financial. It executes an action with real-world side effects (waking/powering on hardware), making Execute the appropriate category. Severity is medium because misuse could power on unintended systems, but it is reversible and limited in blast radius.

RECOMMENDED RULE

The rule that runs wake_on_lan safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Mcp Nettools, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For wake_on_lan, this is the rule to start with:

wake_on_lan Rate-limited

wake_on_lan 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.
