About CartCut

Connects Claude, and any other MCP client, to the CartCut video editor running on your computer. Claude edits the project you have open: cutting from a transcript, adding captions, trimming and restaging clips, motion, transitions and effects. Every edit lands in CartCut's own undo history, so ⌘Z takes it back.
