Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "crabcut": {
      "command": "npx",
      "args": [

Common questions

Is Crabcut safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: CRABCUT_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (2.0.7) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

@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

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

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

Setup

Claude Desktop / Cursor

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

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

Cursor Directory

Install in Cursor

Remote (Streamable HTTP)

For n8n, custom integrations, or any client that supports remote MCP:

Endpoint: https://mcp.crabcut.ai/mcp
Auth: Authorization: Bearer sk_live_...
Transport: Streamable HTTP (POST)

Tools

Tool	What it does
`generate_clips`	Start clip generation from a YouTube URL. Returns a `project_id` right away.
`get_project_status`	Check progress and get clips when ready. Clips are sorted by score (best first).
`list_projects`	List your projects with status and clip counts.
`get_clip`	Get full details for a single clip.
`check_usage`	See your plan, remaining credits, and usage.

How It Works

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

Statuses

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

Processing steps: queued → DOWNLOADING_VIDEO → EXTRACTING_AUDIO → TRANSCRIBING → DETECTING_HIGHLIGHTS → CUTTING_CLIPS → EXPORTING_CLIPS → done

Clips: pending → exporting → completed (or failed). The download_url is available when clip_status is completed.

500	Internal server error	Try again later

Webhooks

Pass a callback_url when calling generate_clips to receive a POST when all clips are ready.

Completed:

"event": "project.completed", "project_id": "43dbe622-...", "status": "completed", "source_url": "https://www.youtube.com/watch?v=H51iLa1leOU", "clips": [ { "id": "32538b9c-...", "title": "One Dating Theory Leads to Chaos", "duration": 41.83, "score": 90, "download_url": "https://cdn.crabcut.ai/exports/premium/.../clip-32538b9c-....mp4", "thumbnail_url": "https://cdn.crabcut.ai/exports/premium/.../clip-32538b9c-...-thumb.jpg", "quality": "1080p" } ] }

Failed:

"event": "project.failed", "project_id": "43dbe622-...", "status": "failed", "error": "YouTube video is unavailable", "clips": [] }

Clips are sorted by score (highest first). We retry up to 3 times if your server doesn't respond.

Signature verification (optional): Each callback includes an X-Crabcut-Signature header. Compute HMAC-SHA256 of the request body using SHA-256(your_api_key) as the signing key. Compare with the header value (sha256= ).

Using with n8n

Option A — Webhook (recommended):

Create a workflow with a Webhook trigger node. Copy its URL.
Add an HTTP Request node: POST https://api.crabcut.ai/api/v1/clips/generate with Header Auth (Authorization: Bearer sk_live_...) and body:

"url": "https://www.youtube.com/watch?v=...", "callback_url": "https://your-n8n.com/webhook/abc123" }

3. When clips are ready, the Webhook node receives the payload.

Best clip: {{ $json.clips[0].download_url }}

Option B — Polling loop:

POST to generate clips (same as above, without callback_url).
Wait 15 seconds → GET https://api.crabcut.ai/api/v1/projects/{{ $json.project_id }} → IF status is not completed, loop back to Wait.

REST API

For direct HTTP calls without MCP:

Method	Endpoint	Description
`POST`	`/api/v1/clips/generate`	Start clip generation
`GET`	`/api/v1/projects/:id`	Get project status and clips
`GET`	`/api/v1/projects`	List projects
`GET`	`/api/v1/clips/:id`	Get single clip details
`GET`	`/api/v1/account/usage`	Check credits and plan

Base URL: https://api.crabcut.ai — All endpoints require Authorization: Bearer sk_live_...
