play_music · AutoBot MCP: Risk & Policy

WHAT IT DOES

What play_music does on AutoBot MCP

AI agents invoke play_music to trigger actions in AutoBot 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.

WHY IT NEEDS A POLICY

Why play_music needs a policy

Playing music from a URL initiates an external operation on the device (media playback), which constitutes an execution-type action. It causes side effects on the device state (audio output, network usage) and involves fetching and playing content from an arbitrary URL, which could be misused to play unwanted audio or consume resources.
