create_quad_layout · Moom MCP Server MCP: Risk & Policy

WHAT IT DOES

What create_quad_layout does on Moom MCP Server

AI agents invoke create_quad_layout to trigger actions in Moom 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 create_quad_layout needs a policy

This tool executes programmatic window layout operations on macOS, repositioning and resizing multiple application windows into a 2x2 grid. It triggers external operations (via Moom) whose effects depend on arguments (which display, which windows). While reversible in principle, it's an Execute-class action as it manipulates the OS window environment.
