Overview

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."

Frequently asked questions

What are the runtime requirements?

Python 3.9 or later, MuseScore 3 or 4 installed locally, and the MCP Python SDK (installed via `pip install -r requirements.txt`).

How do I install the MuseScore plugin?

Copy the `musescore-mcp-plugin` folder into your MuseScore plugins directory (e.g., `~/Documents/MuseScore4/plugins` on macOS). Then select the plugin from MuseScore’s Plugins menu and launch it.

Can the server handle multiple voices within a staff?

No. The current limitation is that it cannot understand or navigate between multiple voices within a single staff.

Where does the data live?

The server operates on the local MuseScore file you have open; no data is sent to external servers beyond the LLM client you configure (e.g., Claude Desktop).

Which transport does the server use?

The server communicates via the Model Context Protocol (MCP) over standard input/output (stdio).
