WHAT IT DOES

What system_power does on Omarchy-MCP

AI agents invoke system_power to trigger actions in Omarchy-MCP. 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 system_power is rated High

Tool can reboot or shut down the system, terminating all running processes irreversibly.

RECOMMENDED RULE

The rule that runs system_power safely

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

system_power Rate-limited

system_power 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.
