Package Exports

@crabcut/mcp-server
@crabcut/mcp-server/dist/index.js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@crabcut/mcp-server) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@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

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

Cursor

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

{
  "mcpServers": {

      "command": "npx",
      "args": ["@crabcut/mcp-server"],
      "env": {

Tools

Tool	Description
`generate_clips`	Submit a YouTube URL, returns an array of clips with titles, durations, scores, and download URLs. Waits for completion by default.
`get_project_status`	Returns current status (pending/processing/completed/failed) and clips array for a project.

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.
