Mexico Invoice MCP 🇲🇽 — How can my AI agent issue a CFDI factura electrónica in Mexico?

Remote MCP server that lets any AI agent issue Mexico CFDI 4.0 electronic invoices (factura electrónica, stamped/timbrada through a SAT-certified PAC) via Facturapi. Stateless, bring-your-own credentials, never stores anything.

Live endpoint: https://inv-mx.wishpool.app/mcp · Registry: app.wishpool/mexico-invoice-mcp

Quick start

{
  "mcpServers": {
    "mexico-invoice": {
      "type": "http",
      "url": "https://inv-mx.wishpool.app/mcp",
      "headers": { "x-facturapi-key": "sk_test_..." }
    }
  }
}

Free sk_test_ keys from facturapi.io never reach SAT. Your CSD certificate stays in your own Facturapi account — this server never sees it.

Tools

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.

Develop

node test/serve.js   # local server on :3226
node test/e2e.js     # protocol + validation + fake-key live probes

Safety

Pure stateless translation layer. The SAT/PAC certification burden sits with Facturapi; credentials travel per-request in headers, nothing is stored. Privacy policy.
