Arquitetura

Code
src/
  index.js              → Entrypoint: cria McpServer, conecta StdioServerTransport
  registerTools.js      → Registra todas as tools no servidor
  handlers/             → Um arquivo por tool handler
    validateCPF.js
    generateCPF.js
    validateCNPJ.js
    generateCNPJ.js
    validateCEP.js
    searchCEP.js
    getCurrencyQuote.js

Design: Tools independentes

Cada tool é autocontida. Os handlers não dependem de outros arquivos do projeto — cada um contém toda a lógica necessária para funcionar. Isso significa que alguns códigos podem estar duplicados entre handlers, e isso é intencional. O objetivo é:

  • Zero acoplamento: cada tool pode ser entendida, testada e modificada isoladamente
  • Facilidade de contribuição: basta criar um handler novo em src/handlers/ e registrar em registerTools.js

Convenção de idioma

  • pt-BR (português brasileiro): tudo que o usuário final vê ou interage — nomes de tools, parâmetros, descrições, mensagens de retorno, propriedades do JSON de resposta.
  • Inglês: código interno — variáveis, funções, imports, lógica, nomes de arquivos

Exemplo: a tool se chama validar_cpf, mas a função interna é validateCPF.

Contribuindo

Contribuições são muito bem-vindas! Sinta-se livre para:

  • Implementar novas tools da lista de planejadas acima
  • Reportar bugs via Issues
  • Sugerir novas funcionalidades que não estão na lista
  • Melhorar documentação ou testes

Padrões para novas tools

  • Handler exporta uma função nomeada (em inglês)
  • Input schema usa z.object() do zod
  • Handler retorna { content: [{ type: "text", text: JSON.stringify(result) }] }
  • Nomes de tools, parâmetros e descrições em pt-BR
  • Código interno em inglês
  • Cada handler é independente — não importe outros handlers

Stack

  • Runtime: Node.js (ESM)
  • Execução: tsx
  • Schema: zod
  • MCP SDK: @modelcontextprotocol/sdk
  • Testes: vitest
