WHAT IT DOES

What convert_audio_format does on MusicGPT MCP Server

AI agents use convert_audio_format 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 convert_audio_format needs a policy

Audio format conversion creates or modifies a file (the converted output) reversibly. The original file can still be preserved, and the operation can be undone or repeated. This is characteristic of Write operations, not Read (no mere retrieval), Execute (no arbitrary command execution), or Destructive (no irreversible deletion).

From the tool's definition Tool description states it converts audio files to "a different format". This modifies the audio file's format/encoding while preserving the underlying audio data (a reversible transformation).
