WHAT IT DOES

What cut_audio does on MusicGPT MCP Server

WHY IT NEEDS A POLICY

Why cut_audio needs a policy

The tool modifies audio by trimming it to a specified duration. This is a Write operation (reversible data modification), not Destructive because trimming is not irreversible — the original file remains available or can be regenerated, and the operation is predictable and bounded by explicit parameters.

From the tool's definition Tool description states 'Cut or trim audio to a specific duration' — a reversible modification operation that alters audio content without permanent deletion or execution of arbitrary code.
