prevent_sleep
Prevent the Mac from sleeping for a specified duration using caffeinate. The assertion is transient — it auto-releases when the timer elapses; no manual stop is required.

What prevent_sleep does on Iconnect
AI agents invoke prevent_sleep to trigger actions in Iconnect. 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 prevent_sleep is rated High
This tool executes an external system command (caffeinate) that modifies the Mac's power management state. It triggers an OS-level operation with side effects (preventing sleep), making it Execute category. Misuse could keep a machine awake indefinitely or drain battery, hence medium severity.
From the tool's definition 'Prevent the Mac from sleeping for a specified duration using caffeinate' — runs the caffeinate system command to alter power management behavior
Attacks that exploit this kind of access
The rule that runs prevent_sleep safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Iconnect, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For prevent_sleep, this is the rule to start with:
prevent_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 Iconnect, apply this rule, and every prevent_sleep call is checked against it from then on.
Questions about prevent_sleep
Prevent the Mac from sleeping for a specified duration using caffeinate. The assertion is transient — it auto-releases when the timer elapses; no manual stop is required. It is categorised as a Execute tool in the Iconnect MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Iconnect MCP server in PolicyLayer and add a rule for prevent_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 Iconnect. Nothing to install.
prevent_sleep is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the prevent_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.
Set action: deny in the PolicyLayer policy for prevent_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.
prevent_sleep is provided by the Iconnect MCP server (iconnect-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
