Melrōse Music MCP server

This is a small helper that lets your AI create and play music using Melrōse, a tool where you write melodies as code. It is handy if you like music, are curious about making tunes with your AI, or want to hear a quick idea played out loud. You do not need to be a musician to try it.

What this MCP server does

You ask your AI for a tune, like a short melody or a famous song opening. The AI writes that tune in the Melrōse music language, which is a way of writing notes as text. It then asks this helper to play that text through Melrōse. Melrōse sends the notes to a MIDI receiver, such as a music program or a hardware keyboard, and you hear the music. You can also ask the AI to change the tempo or pick a different output device.

What you can do with it

• Play a short melody you describe in words
• Play the opening of a well-known tune
• Change the tempo to make it faster or slower
• List the MIDI devices Melrōse can send music to
• Switch to a different output device
• Hear a chord or a few notes played back

Try asking your AI

• “Play the music sequence C D E”
• “Play the first bar of Fur Elise”
• “Play the notes of Frere Jacques”
• “Change the tempo in Melrōse to a lower value”

What it gives back to you

You get a short confirmation in the chat, like the AI saying it played the tune at a certain tempo. For a play request, it often shows how long the music took, for example a few seconds. For device requests, it lists the MIDI devices it found. You hear the actual music through your MIDI setup, not in the chat.
