Tools & Capabilities Breakdown

Brasil Data MCP Tools (15)

consultar_cnpj

Consulta dados cadastrais de uma empresa brasileira pelo CNPJ na Receita Federal (via BrasilAPI). Retorna em JSON: razão social, nome fantasia, situação cadastral (ativa/baixada/etc), data de abertura, endereço completo, CNAE principal e secundários, sócios (QSA), capital social, natureza jurídica, porte (MEI/ME/EPP/Demais), telefones, e-mail, simples nacional/MEI. Use quando o usuário pedir informações sobre uma empresa identificada por CNPJ. Fonte: BrasilAPI por padrão (sem chave), inclusive CNPJ alfanumérico (IN RFB 2.229/2024). Se a variável de ambiente CPFCNPJ_TOKEN estiver definida, usa o provedor premium cpfcnpj.com.br (dados oficiais em tempo real, pacote configurável) e cai para a BrasilAPI se o provedor falhar; aí o campo 'fonte' na resposta indica a origem. Sem o token a resposta é o JSON cru da BrasilAPI, igual às versões anteriores. NÃO use para: CPF (pessoa física), empresas estrangeiras, ou validação local de formato (rejeite formato inválido sem chamar a tool). Aceita CNPJ com ou sem máscara.

consultar_cep

Consulta endereço completo a partir de um CEP brasileiro via BrasilAPI v2 (agrega ViaCEP, Postmon e outros provedores com fallback automático). Retorna em JSON: estado (UF), cidade, bairro, logradouro e, quando disponível, coordenadas geográficas. Use quando o usuário pedir o endereço de um CEP, validar um CEP, ou descobrir cidade/UF a partir de um CEP. NÃO use para: códigos postais de outros países, descobrir CEP a partir de endereço (a operação é só CEP → endereço, não inversa). Aceita CEP com ou sem hífen.

consultar_banco
