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": {
    "ytscribe": {
      "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.
