What extract_audio_segment does on FFmpeg Python MCP Server

WHY IT NEEDS A POLICY

Why extract_audio_segment needs a policy

This tool reads from a video source and writes a new audio file (extraction/creation). It does not delete or overwrite the original, and does not execute arbitrary code or involve financial operations. The primary effect is creating a new derived file, placing it in the Write category. Severity is medium as it processes potentially large media files but has limited blast radius.
