lumiclip MCP Server (io.github.lumiclip/lumiclip)

The io.github.lumiclip/lumiclip Model Context Protocol (MCP) server turns YouTube videos into short-form clips. It accepts a YouTube link, selects strong moments, reframes output for vertical 9:16 video, adds subtitles, and returns download-ready clips for AI assistants that support MCP.

🛠️ Key Features

Convert YouTube videos to short clips
Identify “best moments” from provided links
Reframe clips for vertical (9:16) format
Add subtitles to the output
Produce download-ready clip files

🚀 Use Cases

Short-form repurposing of long YouTube videos
Generating vertical video suitable for mobile viewing
Using the server from MCP-enabled AI assistants (e.g., Claude, Cursor)

⚡ Developer Benefits

Works with any MCP-supported AI assistant
Input is a YouTube URL and output is download-ready clips

⚠️ Limitations

Source material does not specify tool count or additional integrations beyond YouTube and MCP.

@lumiclip/mcp-server

Turn long 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.lumiclip.ai/developers
Run:

bash

LUMICLIP_API_KEY=sk_live_... npx @lumiclip/mcp-server

Setup

Claude Desktop / Cursor

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

json

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

Cursor Directory

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.

Webhooks

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

Completed:

json

{
  "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.lumiclip.ai/exports/premium/.../clip-32538b9c-....mp4",
      "thumbnail_url": "https://cdn.lumiclip.ai/exports/premium/.../clip-32538b9c-...-thumb.jpg",

  ]
}

Failed:

json

{
  "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-Lumiclip-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=<hex>).

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.lumiclip.ai/api/v1/clips/generate with Header Auth (Authorization: Bearer sk_live_...) and body:
json
```
{
  "url": "https://www.youtube.com/watch?v=...",
  "callback_url": "https://your-n8n.com/webhook/abc123"
}
```
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.lumiclip.ai/api/v1/projects/{{ $json.project_id }} → IF status is not completed, loop back to Wait.
