What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

Connection: Runs in the cloud
Transport: Streamable HTTP
Category: Other

Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on the maker’s server: what you ask it goes through their server.
The registry lists no key to fill in.

You need

Runs in the cloudNothing to install; it connects over the internet

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Works in Claude on the web, desktop and mobile:

Open Settings → Connectors
Press Add custom connector
Paste the address below and press Add
If it asks you to sign in, sign in with the maker

https://databr.api.br/mcp

Run this in your terminal

claude mcp add --transport http databr https://databr.api.br/mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "databr": {
      "url": "https://databr.api.br/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "databr": {
      "type": "http",
      "url": "https://databr.api.br/mcp"
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

ChatGPT connects only to servers on the internet:

Open ChatGPT on the web → Settings → Connectors (Apps)
Press Create or Add (some plans need Developer mode under Advanced first)
Paste the address below, give it a name and save
If it asks you to sign in, sign in with the maker

https://databr.api.br/mcp

Menu names can differ slightly by plan and over time.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is DataBR — API de Dados Públicos Brasileiros safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 8 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

DataBR

API de dados públicos brasileiros para agentes de IA, com pagamento on-chain via protocolo x402 (USDC na rede Base).

Sem cadastro. Sem API key. Pague por consulta.

Documentação | Python SDK | MCP Server | MCP Marketplace | Smithery

Como funciona

Agente IA → GET /v1/bcb/selic → 402 Payment Required

→ Paga $0.003 USDC on-chain (Base) → Retry com header X-PAYMENT → 200 OK + dados

O protocolo x402 permite que agentes de IA paguem por dados automaticamente, sem cadastro ou chave de API. Basta ter USDC na rede Base.

Início rápido

curl (explorar sem pagar)

# Health check

curl https://databr.api.br/health

Ver requisitos de pagamento de qualquer endpoint

curl -I https://databr.api.br/v1/bcb/selic

→ 402 Payment Required + JSON com instruções x402

Python SDK

pip install databr

from databr import DataBR

client = DataBR(private_key="0x...") # wallet com USDC na Base

Taxa Selic

selic = client.bcb.selic() print(selic.data) # {"valor": "14.25", ...}

Empresa por CNPJ

empresa = client.empresas.consultar("33000167000101") print(empresa.data["razao_social"])

Due diligence completa

dd = client.empresas.due_diligence("33000167000101")

Formato LLM-ready

ipca = client.economia.ipca(format="context") print(ipca.context) # texto pronto para prompt
