Magenta RealTime 2 MCP Skill

Description: Music generation via Magenta RealTime 2 (MRT2) on JAX/GPU (Windows/Linux) or MLX (Mac live streaming).

Setup (once)

just models-setup
just load-model

Tools

• magentart_ops(operation='status') — Check assets, checkpoint, and model load state.
• magentart_ops(operation='load_model') — Warm JAX model on GPU (first compile is slow).
• magentart_ops(operation='generate', prompt='...', duration_seconds=8) — Text-to-music WAV.
• magentart_ops(operation='generate_from_audio', audio_path='...') — Style from reference WAV.
• magentart_ops(operation='blend', prompts=[...], weights=[...]) — Blend text styles.
• magentart_ops(operation='continue', duration_seconds=4) — Extend prior generation state.
• magentart_agentic_workflow(goal="...") — Plan multi-step generation.

Models

• mrt2_base — higher quality (default; set MAGENTA_RT_MODEL)
• mrt2_small — faster, smaller

Platform notes

• Windows + RTX: offline GPU generation; not live-streaming latency.
• Mac Apple Silicon: use Google's MLX apps/plugins for live MIDI/streaming.
