🎵 Hermes Music Plugin

Music generation plugin for Hermes Agent — powered by Suno AI.

Generate music, compose from MIDI, search & curate your library — all from your agent's toolbox.

Features

• AI Music Generation — Generate songs via Suno AI with style tags, prompts, and model selection (V3.5–V5)
• Dual Track Support — Suno generates 2 tracks per request; both are indexed with independent curation (favorite, archive, play count)
• Local Playback — Play tracks directly via mpg123/ffplay/aplay with auto-stop when switching tracks
• MIDI Composition — Create MIDI files from note names/numbers, then use them as references for AI generation
• Music Library — Browse, search, favorite, archive, and delete songs with per-track granularity
• Multi-Agent — Track which agent created which song with agent_id attribution
• Async Support — Generate in blocking mode (wait for result) or async (poll for status)

Install

# Basic (Suno generation only)
pip install hermes-music

# With MIDI composition support
pip install hermes-music[midi]

# Everything
pip install hermes-music[all]

For local playback, install an audio player:

# Recommended
sudo apt install mpg123

# Alternatives
sudo apt install ffmpeg    # provides ffplay

Setup

Add your Suno API key to ~/.hermes/.env:

SUNO_API_KEY=***

Get a key at sunoapi.org.

The plugin auto-discovers via entry points — no config changes needed. After install, start a new Hermes session and the music tools will be available.

Enable the toolset:

hermes tools enable music

Tools

Examples

# In a Hermes chat session:
"Generate an ambient electronic track for coding"
"Play track 2 of that song"                        # auto-stops track 1
"Stop the music"
"Favorite track 2"
"Archive track 1 — the second one is better"
"Create a MIDI melody with C4 E4 G4 C5 and compose it into jazz piano"
"Search my music library for ambient tracks"

Data Storage

All data lives in ~/.hermes/music/:

~/.hermes/music/
├── audio/          # Downloaded MP3 files (2 tracks per generation)
├── archive/        # Archived/rejected tracks
├── midi/           # Generated MIDI files
└── tasks.json      # Task state & library metadata

Dual Track Model

Suno always generates 2 variants per request. Both are downloaded and indexed. Each track has independent:

• Favorite status
• Play count
• Archive status

Use music_play(task_id, track=1) or music_play(task_id, track=2) to audition both variants, then favorite the best and archive the other.
