About BrasilAPI MCP Server
Empower your AI agent to orchestrate your entire Brazilian institutional research workflow with BrasilAPI, the modern interface for Brazilian public data. By connecting BrasilAPI to your agent, you transform complex national lookups into a natural conversation. Your agent can instantly geolocate addresses via CEP, audit company profiles using CNPJ, and retrieve banking information without you ever touching a government portal. Whether you are conducting KYC checks or managing national logistics, your agent acts as a real-time institutional analyst, ensuring your Brazilian data is always verified and up-to-date.
Pydantic AI validates every BrasilAPI tool response against typed schemas, catching data inconsistencies at build time. Connect 6 tools through Vinkius and switch between OpenAI, Anthropic, or Gemini without changing your integration code. full type safety, structured output guarantees, and dependency injection for testable agents.
What you can do
- CEP Auditing — Retrieve high-resolution address details for any Brazilian zip code (CEP) and identify neighborhoods and cities instantly.
- Corporate Oversight — Audit Brazilian companies using CNPJ to retrieve detailed registration metadata, including tax status and economic activity.
- Banking Intelligence — List all banks operating in Brazil and retrieve official codes and clearing metadata.
- Asset Monitoring — Query vehicle prices from the FIPE table to understand current market valuations in Brazil.
- National Monitoring — List national holidays and retrieve state (UF) metadata from IBGE to coordinate regional operations.
The BrasilAPI MCP Server exposes 6 tools through the Vinkius. Connect it to Pydantic AI in under two minutes — no API keys to rotate, no infrastructure to provision, no vendor lock-in. Your configuration, your data, your control.
