@crabcut/mcp-server

@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.

Setup

• Get an API key at app.crabcut.ai/developers
• Run:

CRABCUT_API_KEY=sk_live_... npx @crabcut/mcp-server

That's it. The server connects via stdio and works with any MCP-compatible client.

Claude Desktop

Add this to your Claude config (claude_desktop_config.json):

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

Cursor

Add to .cursor/mcp.json in your project:

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

Examples

"Make clips from this video"

Just paste a YouTube link in the chat. The assistant will call generate_clips and return your clips when they're ready.

"Only clip the first 5 minutes"

Use start_time: 0 and end_time: 300 to process a specific segment.

How billing works

Each minute of video you process costs credits. You can check your balance anytime with check_usage. Buy credits at crabcut.ai/pricing.
