Details
From the project README@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

How It Works
- Call
generate_clipswith a YouTube URL - Get back a
project_idimmediately - Poll
get_project_statusevery 10–15 seconds (or pass acallback_urlfor 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.

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/generatewith Header Auth (Authorization: Bearer sk_live_...) and body:{ "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:
POSTto generate clips (same as above, withoutcallback_url).- Wait 15 seconds → GET
https://api.lumiclip.ai/api/v1/projects/{{ $json.project_id }}→ IF status is notcompleted, loop back to Wait.
REST API
For direct HTTP calls without MCP:
| Method | Endpoint | Description |
|---|---|---|

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
