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
