set_pause · macOS Control MCP Server MCP: Risk & Policy

WHAT IT DOES

What set_pause does on macOS Control MCP Server

AI agents invoke set_pause to trigger actions in macOS Control MCP Server. 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 set_pause needs a policy

This tool modifies the behavior of PyAutoGUI's execution engine by configuring the pause between automated actions. While it doesn't directly execute GUI actions itself, it configures the runtime execution environment of an automation framework, placing it closest to Execute.

Verdict

set_pause Rate-limited

set_pause 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.

What risk level is set_pause? +

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

Can I rate-limit set_pause? +

Yes. Add a rate_limit block to the set_pause 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 set_pause completely? +
