概览

AI 生成的概览

Brazilayer 让助手查询巴西公共数据——企业登记、制裁名单、合同、市场、大宗商品、基金等——按次以 USDC 付费。

可以做什么
  • 查询 CNPJ 企业登记：状态、经营活动、地址、股东、分支机构，并可按名称、地点、活动或股东搜索
  • 核查制裁与诚信名单、政府采购合同与在招项目，以及企业是否为获授权的金融机构
  • 获取市场数据：带情绪评分的新闻、Selic、IPCA、PTAX 与 Focus 指标、汇率及 BRL 加密溢价
  • 查询大宗商品数据：降雨与霜冻风险、火点、出口、水库及每日简报
  • 查看 CVM 投资基金：资金流、注册信息、排名、持仓与机构动向
  • 按 NCM 编码查询税改待遇、毁林（EUDR）预警与排名、因果链解读，以及一次调用的打包结果或免费样例
适用场景
适合需要巴西企业尽职调查、供应商或交易对手核查、采购与制裁筛查，或巴西宏观、大宗商品与基金数据的场景，且愿意按次以加密货币付费。
运行要求
以本地进程（stdio）运行；Claude Desktop 使用可下载的安装包，其他客户端需从源码运行，依赖 Node.js 与 npm。可选环境变量 BRAZILAYER_PRIVATE_KEY 存放支付调用费用的钱包私钥，钱包需在 Base 上持有 USDC。可选 BRAZILAYER_API_URL 可覆盖默认 API 地址。需要能访问 Brazilayer API 的网络。
安装前请注意
BRAZILAYER_PRIVATE_KEY 是真实钱包私钥，用于签署付款，每次付费调用都会花费 Base 上的 USDC；请使用余额较少的专用钱包。不提供该密钥时只有免费样例与信任检查工具可用。查询内容会发送给第三方 Brazilayer API。

安装

在 SourceWeft 中

  1. 打开 控制台中的 Brazilayer: Brazilian Public Data，将其添加到工作区。
  2. 为需要使用其工具的对话启用该服务。

Desktop only，通过 STDIO。 STDIO 服务会启动本地进程，因此需要 SourceWeft 桌面宿主。

其他 MCP 客户端

参照 仓库 中的启动说明。

README

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.
