WHAT IT DOES

What denoise_audio does on MusicGPT MCP Server

AI agents use denoise_audio 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 denoise_audio needs a policy

This tool processes and modifies audio data by removing background noise, which is a reversible data transformation (the original can be preserved). It creates a new or modified version of the audio, classifying it as Write. Severity is medium as misuse could alter audio files in unintended ways, but effects are not irreversible if originals are retained.

From the tool's definition 'Remove background noise from audio' — modifies an existing audio file by filtering out noise components
