Can Claude convert a video to MP3?
Not on its own. a chat AI can't run programs or write files on your computer. With the GUI Hub Essentials MCP server installed, Claude (Desktop or Code), Cursor, VS Code and other MCP clients can extract the audio from a video as MP3 locally: the assistant calls the ffmpeg_audio tool, which runs FFmpeg on your machine. Files are not uploaded.
