## Why music_play is rated High

This tool executes an action on an external application (Apple Music), controlling playback state. It has no data read/write side effects and no financial or destructive consequences, but it does trigger an external operation whose effect depends on the argument (track id). Misuse potential is very low — worst case is unwanted audio playback.

From the tool's own definition: "'Resume playback or play a track by id' — triggers an external operation (controlling media playback) on the local macOS Music app"

## Use case

AI agents invoke music_play to trigger actions in Apple Apps MCP. 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.
