MuseScore MCP Server

What is MuseScore MCP Server?

This MCP server integrates MuseScore with LLM clients like Claude Desktop, enabling basic music composition through natural language commands. It is intended for musicians and composers who want to use AI to interact with an open MuseScore score programmatically.

How to use MuseScore MCP Server?

Install Python 3.9+ and MuseScore 3 or 4, then clone the repository and install dependencies. Copy the musescore-mcp-plugin into your MuseScore plugins directory, then configure your LLM client (e.g., Claude Desktop) to run server.py via a JSON config. Open MuseScore, load a score, and launch the plugin from the Plugins menu. Afterwards, you can issue natural language queries such as "Compose a simple melody" or "Help me come up with possible chords for the melody."
