Allows turning YouTube videos into short, vertical-format clips with subtitles by providing tools to process video URLs, monitor generation status, and manage project clips.
@crabcut/mcp-server
Turn YouTube videos into short clips — from Claude, Cursor, or any AI assistant that supports MCP.
You give it a YouTube link. It finds the best moments, reframes them for vertical video, adds subtitles, and gives you download links. All from a chat.

How billing works
