WHAT IT DOES

AI agents use change_audio_speed to create or update resources in MusicGPT MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your MusicGPT MCP Server environment.

WHY IT NEEDS A POLICY

Why change_audio_speed needs a policy

This tool creates a modified version of audio without permanently deleting or destroying the original, and does not execute arbitrary code, delete data, or move money. The change is reversible by adjusting speed back to original. It fits the Write category (modifies data reversibly) rather than Execute (no code execution or external operation triggering) or Destructive (original audio preserved).

From the tool's definition Tool modifies audio by changing playback speed ('Change the playback speed of audio'), which is a reversible transformation of existing audio data.
