How to Set Up and Use Melrose Music
Melrose MCP Server connects Claude and other MCP-compatible AI agents to the Melrōse music programming environment, enabling interactive composition and playback of melodies as MIDI output in real time. The server exposes tools for playing musical expressions written in the Melrōse DSL, adjusting playback tempo, listing available MIDI output devices, and switching the active MIDI destination. This makes it possible to have a natural-language conversation with an AI that results in actual music being performed through your DAW or synthesizer.
Prerequisites
- Go SDK (1.19+) installed to build the binary via go install
- A MIDI-capable DAW (Ableton, Logic, GarageBand) or hardware synthesizer connected to your computer
- Claude Desktop or another MCP client that can invoke tools
- macOS, Linux, or Windows with functioning MIDI subsystem
Install the melrose-mcp server binary
Install the MCP server binary using Go's package installer. The binary will be placed in $GOPATH/bin.
go install github.com/emicklei/melrose-mcp@latestConfirm the binary location
Check that the melrose-mcp binary is accessible on your PATH before configuring any MCP client.
which melrose-mcpOpen a MIDI receiver
Launch your DAW or activate a virtual MIDI port so the server has somewhere to send note events. On macOS, the built-in IAC Driver (via Audio MIDI Setup) creates a virtual MIDI bus.
Configure your MCP client
Add the melrōse server entry to your Claude Desktop config or equivalent MCP client configuration, pointing to the installed binary.
Restart Claude Desktop and test
Restart Claude Desktop and ask it to list available MIDI devices to verify the server is running and connected.
Melrose Music Examples
Client configuration
Place this JSON in ~/Library/Application Support/Claude/claude_desktop_config.json on macOS. Update the command path to match where your melrose-mcp binary was installed.
{
"mcpServers": {
"melrose": {
"command": "/Users/yourname/go/bin/melrose-mcp",
"args": []
}
}
}Prompts to try
Use these natural language prompts in Claude Desktop to compose and play music through the Melrōse server.
- "Play the C major scale"
- "Play the first 8 notes of Beethoven's Ode to Joy"
- "Play the C# minor chord at 90 BPM"
- "List all available MIDI output devices"
- "Change the MIDI output to my DAW and play a simple jazz progression"Troubleshooting Melrose Music
No sound when Claude invokes melrose_play
Ask Claude to call melrose_devices to list detected MIDI outputs. If the desired device is missing, open your DAW first and then ask Claude to call melrose_change_output_device to select it.
go install fails with module errors
Ensure Go 1.19+ is installed ('go version'), that your GOPATH is writable, and run 'go env GOPATH' to confirm the expected bin directory. Try 'go install github.com/emicklei/melrose-mcp@latest' again after updating Go.
Claude Desktop does not show the melrose tools
Verify the command path in your config is the absolute path to the melrose-mcp binary and that the binary is executable. Check Claude Desktop logs for startup errors related to the server process.
