WHAT IT DOES

What start_audio_extraction does on Mcp Ffmpeg

AI agents invoke start_audio_extraction to trigger actions in Mcp Ffmpeg. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.

WHY IT NEEDS A POLICY

Why start_audio_extraction needs a policy

This tool executes FFmpeg operations to extract audio from video files. Even though extraction is not inherently destructive, it triggers external command execution that processes user-supplied media files through a job queue system. This represents the Execute category: it runs code/operations whose effects are determined by arguments (input video file, output format, codec settings).

From the tool's definition Tool is named 'start_audio_extraction' and belongs to the mcp-ffmpeg server which performs 'video processing tasks' including transcription and format conversion.
