概覽

AI 產生的概覽

Brazilayer 讓助理查詢巴西公開資料——企業登記、制裁名單、合約、市場、大宗商品、基金等——依每次呼叫以 USDC 付費。

可以做什麼
  • 查詢 CNPJ 企業登記：狀態、營業活動、地址、股東、分支機構，並可依名稱、地點、活動或股東搜尋
  • 核查制裁與誠信名單、政府採購合約與公開招標，以及企業是否為獲授權的金融機構
  • 取得市場資料：附情緒評分的新聞、Selic、IPCA、PTAX 與 Focus 指標、匯率及 BRL 加密溢價
  • 查詢大宗商品資料：降雨與霜害風險、火點、出口、水庫及每日簡報
  • 檢視 CVM 投資基金：資金流、註冊資訊、排名、持股與機構動向
  • 依 NCM 代碼查詢稅改待遇、毀林（EUDR）警示與排名、因果鏈解讀，以及一次呼叫的整合結果或免費樣本
適用情境
適合需要巴西企業盡職調查、供應商或交易對手查核、採購與制裁篩選，或巴西總體經濟、大宗商品與基金資料的情境，且願意依每次呼叫以加密貨幣付費。
執行需求
以本機程序（stdio）執行；Claude Desktop 使用可下載的安裝包，其他用戶端需從原始碼執行，依賴 Node.js 與 npm。選用環境變數 BRAZILAYER_PRIVATE_KEY 存放支付呼叫費用的錢包私鑰，錢包需在 Base 上持有 USDC。選用 BRAZILAYER_API_URL 可覆寫預設 API 位址。需要能連線至 Brazilayer API 的網路。
安裝前請注意
BRAZILAYER_PRIVATE_KEY 是真實錢包私鑰，用於簽署付款，每次付費呼叫都會花費 Base 上的 USDC；請使用餘額較少的專用錢包。未提供該金鑰時僅有免費樣本與信任檢查工具可用。查詢內容會傳送給第三方 Brazilayer API。

安裝

  1. 開啟 儀表板中的 Brazilayer: Brazilian Public Data，將其新增到工作區。

Brazilayer MCP server

Official Brazilian public data for AI agents, paid per call in USDC on Base through the x402 protocol. No account and no API key: the server pays each call from a wallet you configure, and the free tools work without one.

Install

Claude Desktop. Download brazilayer-mcp.mcpb from the latest release and open it. The installer asks for the wallet key, which is optional.

Claude Code, from source:

bash
git clone https://github.com/brazilayer/mcp && cd mcp && npm installclaude mcp add brazilayer -e BRAZILAYER_PRIVATE_KEY=0xYOUR_KEY -- npx tsx "$PWD/servidor.ts"

Other MCP clients (Cursor and others), after the same git clone and npm install:

json
{  "mcpServers": {    "brazilayer": {      "command": "npx",      "args": ["tsx", "/path/to/mcp/servidor.ts"],      "env": { "BRAZILAYER_PRIVATE_KEY": "0xYOUR_KEY" }    }  }}

Configuration

  • BRAZILAYER_PRIVATE_KEY (optional): private key (0x…) of the wallet that pays for calls. It needs USDC on Base. Without it the free tools work, and the paid ones explain the 402 they received.
  • BRAZILAYER_API_URL (optional): defaults to https://api.brazilayer.com.

The key signs real payments. Use a dedicated wallet with a small balance.
