Install Crabcut in Claude Code, Cursor or VS Code

Runs npx -y @crabcut/mcp-server on your machine. Read the scan report first; the gateway never runs local packages.

claude mcp add crabcut -- npx -y @crabcut/mcp-server
Add to Cursor

What the publisher says

From the Crabcut repository's README, as published. We do not edit it. Read it on GitHub

@crabcut/mcp-server

Turn YouTube videos into short clips — from Claude, Cursor, or any AI assistant that supports MCP.

Give it a YouTube link. It finds the best moments, reframes for vertical video (9:16), adds subtitles, and returns download-ready clips.

Quick Start

  1. Get an API key at app.crabcut.ai/developers
  2. Run:
CRABCUT_API_KEY=sk_live_... npx @crabcut/mcp-server

Setup

Claude Desktop / Cursor

Add to your config file — claudedesktopconfig.json for Claude, .cursor/mcp.json for Cursor:

{
  "mcpServers": {
    "crabcut": {
      "command": "npx",
      "args": ["@crabcut/mcp-server"],
      "env": {
        "CRABCUT_API_KEY": "sk_live_..."
      }
    }
  }
}

How It Works

  1. Call generate_clips with a YouTube URL
  2. Get back a project_id immediately
  3. Poll getprojectstatus every 10–15 seconds (or pass a callback_url for webhook)
  4. When done, clips are sorted by score (best first), each with a download_url

Statuses

Project: pending → processing → completed (or completednoclips / failed)

Processing steps: queued → DOWNLOADINGVIDEO → EXTRACTINGAUDIO → TRANSCRIBING → DETECTINGHIGHLIGHTS → CUTTINGCLIPS → EXPORTING_CLIPS → done

Clips: pending → exporting → completed (or failed). The downloadurl is available when clipstatus is completed.
