2 things to look at

  • no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
  • 1 stars1 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

Estrutura minima (Python)

from fastmcp import FastMCP
mcp = FastMCP("nome-do-servico")

@mcp.tool()
def minha_ferramenta(parametro: str) -> str:
    """Descricao clara do que faz."""
    return resultado

Boas praticas

  • Cada tool faz UMA coisa
  • Descricoes claras nos tools
  • Tipos explicitos em parametros
  • Erros retornam mensagem util, nao stack trace
  • Auth via env vars
  • Rate limiting se API externa tem limites
  • Timeout em chamadas externas

Registro em ~/.claude/.mcp.json

{
  "mcpServers": {
    "nome": {
      "command": "python",
      "args": ["/caminho/server.py"]
    }
  }
}

Seguranca

  • Nunca expor credenciais nos logs
  • Validar todo input
  • HTTPS para chamadas externas
  • Permissoes minimas
