Peru Invoice MCP 🇵🇪 — How can my AI agent issue a factura o boleta electrónica in Peru?

Remote MCP server that lets any AI agent issue Peru electronic CPE (comprobante de pago electrónico — factura for B2B, boleta for consumers), declared to SUNAT via Nubefact. Stateless, bring-your-own credentials, never stores anything.

Live endpoint: https://inv-pe.wishpool.app/mcp · Registry: app.wishpool/peru-invoice-mcp

Quick start

{
  "mcpServers": {
    "peru-invoice": {
      "type": "http",
      "url": "https://inv-pe.wishpool.app/mcp",
      "headers": {
        "x-nubefact-ruta": "https://api.nubefact.com/api/v1/<your-hash>",
        "x-nubefact-token": "<your-token>"
      }
    }
  }
}

A free DEMO account at nubefact.com gives you both a RUTA and a TOKEN (menu Api-Integración). The same credentials switch to production at the account level (numbering resets on go-live), so results report mode: "nubefact-account" honestly — verify demo vs production in your Nubefact dashboard.

Tools

⚠️ Numbering is merchant-managed. This server is stateless and does not track sequences — the caller supplies serie and the next numero. Reusing a numero is rejected by SUNAT; skipping one leaves a gap.

Owner policy guardrails ride optional headers (x-agentpay-max-amount, x-agentpay-approval-above, x-agentpay-allowed-tools) — set by the human owner in client config; the agent cannot relax them. The cap applies to the invoice total in PEN.

node test/e2e.js     # protocol + validation + IGV math + fake-cred live probes

Safety

Pure stateless translation layer. The SUNAT certification burden sits with Nubefact (OSE/PSE); credentials travel per-request in headers, nothing is stored. Privacy policy.
