Suno Music - AI Music Generation
Generate music using Suno AI's API.
Setup (One-Time)
- Sign in to suno.ai
- Open browser DevTools (F12) → Console tab
- Run:
document.cookie - Find the
__session=eyJ...part (it's a long JWT token) - Export it:
export SUNO_COOKIE="__session=eyJ..."
Note: The __session token expires after ~1 hour. You'll need to refresh it periodically.
Usage
Run the generation script:
python3 ~/.claude/skills/suno-music/generate_music.py "your prompt here" [options]Options
| Option | Description | Default |
|---|---|---|
--custom | Treat prompt as lyrics (not description) | False |
--tags | Style/voice tags (e.g., "female voice, pop, upbeat") | None |
--title | Song title | None |
--instrumental | Generate instrumental only (no vocals) | False |
--output | Output directory path | ./generated_music |
--model | Model key (e.g., chirp-auk-turbo) | Default free model |

Songs are saved with format: {timestamp}_{sanitized_title}_{n}.mp3
Example: 20260106_morning_light_1.mp3
Suno generates 2 variations per request by default.
Credits
- Free tier: 50 credits/day (renews daily)
- Each generation uses 10 credits (5 per song × 2 variations)
- So you can generate 5 songs per day on the free tier

python3 ~/.claude/skills/suno-music/generate_music.py --creditsModels
