Cut Express is a video editing tool that connects to Claude via the Model Context Protocol, letting users describe edits in plain language and receive a rendered MP4 in return. Claude analyzes uploaded clips, reads transcripts, and writes a full timeline including cuts, captions, color grades, and audio. Cut Express then renders the result at up to 2K resolution in 9:16 or 16:9 format. Users can iterate on any version by sending follow-up messages, and every video retains an editable JSON timeline.
