brasilapi-mcp
An MCP server that gives AI assistants Brazilian public data through BrasilAPI: company registry lookups by CNPJ (including partners), addresses by CEP, offline CNPJ/CPF validation and national holidays.
It was built from experience with company due-diligence (KYC) workflows, where an agent has to check that a company exists, is active and who its partners are, and must not trust a number that fails its check digits. It is an independent project and is not affiliated with BrasilAPI or the Receita Federal.
