Security Report

7.2

Moderate7.2Low Risk

A well-structured MCP server for Brazilian financial/commodity data with proper authentication via x402 payment protocol. Private keys are correctly managed via environment variables (not hardcoded), and all user inputs are validated with Zod schemas and URL-encoded before API calls. The server acts as a thin client with no direct database access or dangerous operations. Minor code quality observations around error handling breadth do not materially impact security posture. Supply chain analysis found 1 known vulnerability in dependencies (0 critical, 1 high severity).

pedagio-mcp: servidor MCP

Distribuição pública: este servidor é publicado em github.com/brazilayer/mcp (instalação para usuários finais lá). Esta pasta é a fonte interna; alterações aqui devem ser espelhadas no repo público.

Cliente fino da API pública do pedagio (SPEC §8): expõe os dados de CNPJ como ferramentas MCP pagáveis via x402. Sem acesso direto ao banco: cada ferramenta chama a API HTTP e paga com USDC (rede Base) usando a carteira configurada.

Instalação (Claude Code)

git clone https://github.com/aladaf/pedagio && cd pedagio/mcp && npm install
claude mcp add pedagio -e BRAZILAYER_PRIVATE_KEY=0xSUACHAVE -- npx tsx /caminho/para/pedagio/mcp/servidor.ts

Instalação (Claude Desktop / Cursor)

{
  "mcpServers": {
    "pedagio": {
      "command": "npx",
      "args": ["tsx", "/caminho/para/pedagio/mcp/servidor.ts"],

        "BRAZILAYER_PRIVATE_KEY": "0xCHAVE_DA_CARTEIRA_QUE_PAGA"
      }
    }
  }
}

Variáveis

BRAZILAYER_API_URL: default https://api.brazilayer.com
BRAZILAYER_PRIVATE_KEY: chave privada (0x…) da carteira que paga as chamadas (precisa de USDC na rede Base; na testnet, USDC de faucet na Base Sepolia). Sem ela, apenas cnpj_obter_amostra funciona; as demais explicam o 402.

⚠️ A chave configurada aqui assina pagamentos reais. Use uma carteira dedicada com saldo pequeno.

Escolha da integração x402↔MCP (SPEC §8)

Avaliado em 2026-07-20: adotados os pacotes oficiais @x402/fetch + @x402/evm (v2.19), que envelopam o fetch com o fluxo 402→assinatura→retry, e o servidor MCP usa esse fetch pagante em cada ferramenta. Alternativas de bridge MCP de terceiros foram descartadas por serem menos mantidas que o SDK oficial.
