show_moom_menu · Moom MCP Server MCP: Risk & Policy

WHAT IT DOES

What show_moom_menu does on Moom MCP Server

AI agents invoke show_moom_menu 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 show_moom_menu needs a policy

This tool triggers an external UI action (displaying a popup menu) in macOS via Moom. It causes a side effect in the UI environment rather than simply reading data, making it Execute. The blast radius is low since it only surfaces a menu and does not modify or delete data.
