The stack covers what an AI-operated Argentine company needs to exist and
operate: identity (AFIP/ARCA), payments, invoicing, banking, government
filings, communications, and a forensic audit log. The deepest package,
[`@ar-agents/mercadopago`](./packages/mercadopago), exposes 89 typed tools
across the agent-relevant Mercado Pago API surface for the
[Vercel AI SDK](https://ai-sdk.dev) 6 `Experimental_Agent`, one of the 33
packages in the `@ar-agents/*` stack:
> Payments · Subscriptions · Checkout Pro · Marketplace OAuth · Order Management ·
> Customers · Cards · Cuotas · QR · 3DS · Point devices · Stores+POS ·
> Account/Balance/Settlements · Webhooks · Disputes · Lookups · Bank Accounts
Edge Runtime. Vercel KV adapters for state, OAuth, idempotency, and audit.
OpenTelemetry instrumentation. Deterministic idempotency by default.
Programmatic HITL on irreversible operations.
```bash
pnpm add @ar-agents/mercadopago ai zod
```

Deploys [`apps/mp-hello`](./apps/mp-hello), a runnable agent on Vercel with
Edge Runtime API routes, MP webhook handler, and Upstash-backed subscription
state. Around 2 minutes from click to live.
## Governance layer for AR sociedades-IA
Since Argentina announced a sociedad-IA regime (Sturzenegger,
28-abr-2026), this repo additionally hosts a complete open-source
governance scaffolding for AI-only Argentine corporations:
- **6 RFCs (001–006)** — civil liability (3-layer) / discovery / cross-
jurisdictional reciprocity / operational-log wire format / Ed25519
asymmetric extension / hash-chained ledger + external anchoring. All
CC-BY-4.0. Documents the legislation can cite by reference.
- **2 frozen test-vectors files** — 7 RFC-004 HMAC vectors + 3 RFC-005
Ed25519 vectors. Byte-exact deterministic signatures. Reference impl
passes all 10 (103 vitest tests in 6 files).
- **Public certifier** at [`ar-agents.ar/certifier`](https://ar-agents.ar/certifier) —
paste any URL, score 0-100 against RFC-002 + RFC-004 + RFC-005 in
seconds. Programmatic API at `/api/certifier?url=...`. Reference impl
self-scores 100/100 Rating A. Cookbook recipes 26 (single-shot) +
27 (monitoring) + 28 (operator readiness).
- **Live time-series** at `/api/conformance-history` — 365-entry capped
KV-backed history per URL, daily Vercel cron auto-population.
- **Public well-known endpoints** — `/.well-known/agents.json` (RFC-002),
`/.well-known/sociedad-ia/verify-key?challenge=` (RFC-004 § 5
challenge-response), `/.well-known/sociedad-ia/keys` (RFC-005 § 4
Ed25519 public key publication).
- **Bilingual narrative pages** — [`/legislacion`](https://ar-agents.ar/legislacion)
(Spanish for AR legislators) + [`/en/legislation`](https://ar-agents.ar/en/legislation)
(English for international press / comparative-law scholars).
- **One-page regulator brief** at [`/auditor`](https://ar-agents.ar/auditor) —
print-friendly, 7-minute read, every claim links to evidence.
- **Public registry** at [`/registro`](https://ar-agents.ar/registro) —
self-listed implementations with live cert-badges per entry.
- **Glossary, outreach templates, BibTeX refs, visual timeline** —
see `/glossary`, `/share`, `/refs`, `/timeline`.
For an outsider arriving cold: start at the [auditor's brief](https://ar-agents.ar/auditor)
or the [legislative synthesis](https://ar-agents.ar/legislacion).

import {

mercadoPagoTools,
InMemoryStateAdapter,
} from "@ar-agents/mercadopago";
const mp = new MercadoPagoClient({

});
const agent = new Agent({
model: "anthropic/claude-sonnet-4-6",
tools: mercadoPagoTools(mp, {
state: new InMemoryStateAdapter(), // swap for VercelKVStateAdapter in prod
backUrl: "https://yoursite.com/subscription/done",
}),
stopWhen: stepCountIs(8),
});
const { text } = await agent.generate({
prompt: "Creá una subscription mensual de $1000 ARS para customer@example.com.",
});

## How it compares
| | `@ar-agents/mercadopago` | `mercadopago` (official) | Stripe Agent Toolkit |
| ---------------------------------------------- | :----------------------: | :----------------------: | :------------------: |
| Vercel AI SDK 6 tool schemas | ✓ | no | ✓ (Stripe) |
| Argentine-specific (cuotas, ARCA, AR phone) | ✓ | partial | no |
| Tool count | 89 | thin REST client | 26 (Stripe) |
| Webhooks: HMAC + dedup + replay window | ✓ | client only | ✓ |
| Edge Runtime + Vercel KV adapters | ✓ | Node-only | optional |
| OpenTelemetry instrumentation | ✓ | no | no |
| Deterministic idempotency by default | ✓ | no | no |
| Programmatic HITL on irreversible ops | ✓ | no | no |
| MercadoPago coverage | full | full | n/a |
Both official SDKs are excellent at what they do (generic REST clients for
their respective APIs). `@ar-agents/mercadopago` is opinionated for the
agent-operating-an-Argentine-business case, and composes with `mercadopago`
under the hood when needed. See [`MIGRATION.md`](./packages/mercadopago/MIGRATION.md).

The agent picks tools from natural-language prompts. Each package is an
independent npm release; there are no cross-package runtime dependencies
beyond the optional adapter subpaths, so you only ship the surface you use.
## Other AR primitives in this monorepo
Same approach, applied to the rest of the stack an Argentine business needs:
| Package | Tools | What it does |
| --- | :---: | --- |
| [`@ar-agents/identity`](./packages/identity) | 2 | CUIT/CUIL validation + AFIP/ARCA padrón lookup (constancia con monotributo + condición IVA). WSAA SOAP via subpath. |
| [`@ar-agents/identity-attest`](./packages/identity-attest) | 5 | Verification orchestrator (WhatsApp OTP, email magic-link, Auth0, Magic.link, MP Identity), returns HMAC-signed attestation with `trustLevel`. |
| [`@ar-agents/whatsapp`](./packages/whatsapp) | 6 | WhatsApp Business Cloud API. Webhook + HMAC. AR phone normalizer. `scopedTo` mode binds outbound tools to a single sender. |
| [`@ar-agents/facturacion`](./packages/facturacion) | 10 | AFIP/ARCA factura electrónica (WSFE). Factura A/B/C, NC/ND, FCE MiPyMEs. Local pre-flight validator. |
| [`@ar-agents/banking`](./packages/banking) | 5 | CBU/CVU validation + bank/PSP lookup + BCRA Central de Deudores. |
| [`@ar-agents/shipping`](./packages/shipping) | 6 | Andreani (full) + OCA + Correo Argentino. Provincia + CPA helpers. |
| [`@ar-agents/mcp`](./packages/mcp) | wraps all | Model Context Protocol server. Drop the toolkit into Claude Desktop, Cursor, any MCP host. |
Each package ships a `README.md` for humans and an `AGENTS.md` for LLMs reading
the docs at runtime, following the [agents.md](https://agents.md/) format
(tool-selection rules, result schemas, error patterns).
## Live demos
| App | URL | Shows |
| --- | --- | --- |
| Landing | | Toolkit overview |
| `cuit-hello` | | CUIT validation + ARCA padrón (real AFIP cert) |
| `whatsapp-hello` | | Billing assistant: MP composed with identity, identity-attest, whatsapp |
| `mp-hello` | dev-only | MP Subscriptions full flow (`pnpm dev`, port 3013) |
## Develop
```bash
pnpm install
pnpm test # 719 tests across 8 packages
pnpm typecheck
pnpm build
pnpm dev # mp-hello on http://localhost:3013
```
Requires Node 20+ and pnpm 10+. CI runs build, typecheck, coverage,
manifest-drift, publint, arethetypeswrong, and size-limit on every push.

## Stability
All packages are pre-1.0. Public API may evolve in 0.x; we follow semver, so
minor bumps may include breaking changes and patch bumps never do. Pinning a
minor in production is safe.
