ViaCep integrations

Connect ViaCep to any other app, or use it from your AI client over MCP. ViaCep is a Brazilian postal code (CEP) lookup service. Callers can look up a CEP to get the street (logradouro), complement, neighbourhood (bairro), city (localidade), state (UF), IBGE municipality code, DDD area code and SIAFI code, and can search in the reverse direction by state, city and street name to list matching CEPs. Responses are available as JSON, XML or piped text. No credentials required.
