music21 MCP Server

Servidor MCP de análise musical usando music21 + FastMCP + Pydantic.

Complementa o seu MIDI-compostion-tools-MCP focado em construção: enquanto o toolkit constrói composições, este servidor analisa arquivos existentes.


🛠 Tools disponíveis (8)

Tool O que faz
score_info Visão geral: título, compositor, partes, assinaturas, duração
analyze_key Detecta tonalidade (algoritmo Krumhansl-Schmuckler) com confiança
analyze_harmony Extrai acordes, numerais romanos, cadências, progressão resumida
analyze_melody Contorno, âmbito, intervalos, clímax, lista de notas
analyze_rhythm Fórmula de compasso, tempo, densidade, síncope, padrões rítmicos
analyze_form Detecta seções (A, B, A'…), repetições, forma geral (ABA, Rondó…)
check_counterpoint Erros de voice-leading: quintas paralelas, cruzamentos, saltos
analyze_motifs Motivos recorrentes e suas transformações (inversão, retrogrado…)

📦 Instalação

# 1. Clonar / copiar a pasta music21-mcp
cd music21-mcp

# 2. Criar ambiente virtual (recomendado)
python -m venv .venv
source .venv/bin/activate      # Linux/macOS
.venv\Scripts\activate         # Windows

# 3. Instalar dependências
pip install -r requirements.txt

▶️ Executar

python server.py

O servidor roda via stdio — padrão para integração local com Claude Desktop, Cursor, etc.


⚙️ Configuração no Claude Desktop

Adicione ao seu claude_desktop_config.json:

{
  "mcpServers": {
    "music21": {
      "command": "python",
      "args": ["/caminho/absoluto/para/music21-mcp/server.py"],
      "env": {}
    }
  }
}

Dica: se usar virtualenv, use o Python do venv: "/caminho/para/music21-mcp/.venv/bin/python"


🔗 Integração com seu MCP Music Toolkit

Pipeline típico:

music21 MCP (analyze_harmony)
    → detecta progressão do arquivo
    → passa para seu toolkit (comp_set_progression)
    → gera variação ou arranjo

music21 MCP (check_counterpoint)
    → aponta erros no MIDI gerado
    → seu toolkit (theory_voice_lead_sequence)
    → corrige o voice leading
