Overview

AI-generated overview

A remote MCP server giving assistants Brazilian public data lookups: CNPJ company records, CEP postal codes, Selic/IPCA/PTAX rates, holidays and bank ISPB…

What it does
It exposes Brazilian reference-data lookups to an assistant: CNPJ company registration data, CEP postal-code lookups, central-bank indicators such as Selic, IPCA and PTAX exchange rates, national holidays, and bank codes (ISPB). It runs as a hosted remote endpoint, so no local package is installed. Calls are billed individually in USDC through the x402 payment scheme.
When to use it
Worth adding when an assistant regularly needs Brazilian business, address, banking or economic-indicator data, for example validating a supplier's CNPJ, resolving a CEP, or checking current Selic, IPCA or PTAX figures. Less useful if you only need occasional lookups or data outside Brazil.
Requirements
A remote MCP client that supports streamable HTTP, plus network access to the provider's endpoint. No account, API key or environment variable is declared. Because calls are paid per use in USDC via x402, a funded crypto wallet or payment setup compatible with x402 is needed.
Before you install
Each call costs USDC under the x402 pay-per-call scheme, so usage spends real funds and costs should be monitored. Payment typically requires a crypto wallet or signing key; treat any such credential as sensitive. Lookup queries are sent to a third-party hosted service, so avoid submitting confidential data.
