NPM package @chrischall/musescore-mcp
Claude Code 
claude mcp add musescore-mcp -e 'MUSESCORE_WS_PORT=<MUSESCORE_WS_PORT>' -e 'MUSESCORE_OUTPUT_DIR=<MUSESCORE_OUTPUT_DIR>' -- npx -y @chrischall/musescore-mcp@1.2.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "musescore-mcp": {
            "command": "npx",
            "args": [
                "-y",
                "@chrischall/musescore-mcp@1.2.0"
            ],
            "env": {
                "MUSESCORE_WS_PORT": "<MUSESCORE_WS_PORT>",
                "MUSESCORE_OUTPUT_DIR": "<MUSESCORE_OUTPUT_DIR>"
            }
        }
    }
}

Environment variables

  • MUSESCORE_WS_PORT Override the fetchproxy WebSocket port (default 37149).
  • MUSESCORE_OUTPUT_DIR Directory every file-writing tool is confined to (default ~/Downloads): an output_path/output_dir outside it is refused, a relative path is resolved against it, and musescore_svg_to_pdf only reads svg_paths from inside it.
