# pedagio-mcp — servidor MCP
> **Distribuição pública:** este servidor é publicado em **[github.com/brazilayer/mcp](https://github.com/brazilayer/mcp)**

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)
```bash
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)
```json
{
"mcpServers": {
"pedagio": {
"command": "npx",
"args": ["tsx", "/caminho/para/pedagio/mcp/servidor.ts"],
"env": {
"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 — 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.
