WHAT IT DOES

What system_sleep does on AirMCP

AI agents invoke system_sleep to trigger actions in AirMCP. 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_sleep is rated High

This tool triggers an external system-level operation (sleep) on the Mac. It is not merely reading data, nor is it destructive in the sense of deleting data, but it executes a significant system action that interrupts all running processes and user sessions. Misuse by an AI agent could disrupt work, interrupt running tasks, or cause data loss in unsaved applications, giving it a high severity blast radius.

RECOMMENDED RULE

The rule that runs system_sleep safely

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

system_sleep Rate-limited

system_sleep 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.

The button opens the PolicyLayer dashboard: create your workspace, connect AirMCP, apply this rule, and every system_sleep call is checked against it from then on.

FAQ

Questions about system_sleep

What does the system_sleep tool do? +

Put the Mac to sleep. It is categorised as a Execute tool in the AirMCP MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.

How do I enforce a policy on system_sleep? +

Register the Air MCP server in PolicyLayer and add a rule for system_sleep: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches AirMCP. Nothing to install.

What risk level is system_sleep? +

system_sleep is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.

Can I rate-limit system_sleep? +

Yes. Add a rate_limit block to the system_sleep rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block system_sleep completely? +

Set action: deny in the PolicyLayer policy for system_sleep. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides system_sleep? +

system_sleep is provided by the Air MCP server (airmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
