Protocolo MCP

Host (Claude) → Client → [stdio] → Este Server
                                      ├── tools/list → retorna 3 tools
                                      └── tools/call → executa e retorna resultado

Aprendizados-chave

MCP Server expõe tools que qualquer host MCP-compatível pode invocar
server.tool(name, description, schema, handler) registra uma tool
Retorno padrão: { content: [{ type: 'text', text: '...' }] }
isError: true sinaliza falha na execução
Transporte stdio: comunicação direta entre processos (sem HTTP)
