Quick Start

Remote MCP URL: https://mcp.youtubetranscript.dev

Claude, Cursor, and VS Code can add this as a remote MCP connector. ChatGPT users must enable Developer mode and create a custom app with this URL; availability depends on the workspace plan. OAuth-capable clients sign in once, so no API key is needed in the chat.

Full walkthrough: youtubetranscript.dev/resources/mcp-server

API key clients (if the tool has no OAuth): send Authorization: Bearer YOUR_API_KEY. x-api-token still works. Get a key from the account page.

Run locally (optional): npm install && npm run build && npm run start:http — then connect to http://localhost:8080.

Replace YOUR_API_KEY with your API key from youtubetranscript.dev/dashboard/account.

Configuration

Server Environment (for deployment)

Note: HTTP mode uses OAuth where the client supports it, including compatible Claude, Cursor, VS Code, and Grok clients. ChatGPT requires Developer mode and a custom MCP app. API-key clients can send Authorization: Bearer / x-api-token from the client. Do not put user keys in server env. For stdio mode, set YTSM_API_KEY. Always set YTSM_BASE_URL to https://www.youtubetranscript.dev — the apex host 301s and breaks POST/auth.

Tools Reference

get_stats

Credits left, transcripts created, plan, rate limit. No parameters.

transcribe_v2

Fast caption-based transcript (no ASR). Uses manual or auto captions only.

list_transcripts

List transcript history for the authenticated user.

get_transcript

Get full transcript by video_id.

delete_transcript

Delete transcript records.

*Provide at least one of ids or video_id.

Deployment (Optional)

For production, deploy to a service that supports long-lived connections (e.g. Cloud Run, Railway, Fly.io). Avoid serverless (Vercel, Lambda) for MCP — timeouts and concurrency limits cause issues.

docker build -f Dockerfile.cloudrun -t gcr.io/YOUR_PROJECT/youtube-transcript-mcp .
docker push gcr.io/YOUR_PROJECT/youtube-transcript-mcp
gcloud run deploy youtube-transcript-mcp --image gcr.io/YOUR_PROJECT/youtube-transcript-mcp ...

Stdio (Alternative)

Run as a subprocess instead of HTTP. Required: set YTSM_API_KEY in env (API key is not passed per-request for stdio).

{
  "mcpServers": {
    "youtubetranscript": {
      "command": "node",
      "args": ["dist/index.js"],
      "env": { "YTSM_API_KEY": "YOUR_API_KEY" }
    }
  }
}

Run from the project directory after npm run build. For globally installed package, use the path to dist/index.js in the package.

Development

npm install
npm run build
npm test
npm run start:http   # Local HTTP server (port 8080)

Quick test all tools (requires YTSM_API_KEY in env):

npm install && npm run build
export YTSM_API_KEY=your_key   # bash/mac
$env:YTSM_API_KEY="your_key"   # PowerShell
npm run test:all

See QUICK_TEST.md for full testing instructions.
