## Before you call it

1. Search the library before generating. A match costs no generation
2. Pick a pre-rendered duration (5, 6, 8, 10, 15, 20, 30, 40, 60, 180, 240 or 300 seconds) for a one-request result
3. Download tracks straight away. URLs expire after 900 seconds by default
4. Treat stream URLs as secrets. They carry the customer access token

## Connect

```bash
curl -X POST https://music-api.mubert.com/api/v3/public/tracks \
  -H "customer-id: $MUBERT_CUSTOMER_ID" -H "access-token: $MUBERT_ACCESS_TOKEN" \
  -H "content-type: application/json" \
  -d '{"playlist_index":"1.0.0","duration":60,"format":"mp3","intensity":"medium","mode":"track"}'
```

```bash
claude mcp add --transport http mubert-music https://mcp.mubert.com/mcp
