# Agent Instructions — velasyaromas

This document describes how AI agents can interact with velasyaromas's online store at https://velasyaromas3.mitiendanube.com.

## Commerce Protocol (UCP)

This store implements the [Universal Commerce Protocol](https://ucp.dev) for agent-driven commerce.

### Discovery

```
GET https://velasyaromas3.mitiendanube.com/.well-known/ucp
```

Returns the store's UCP merchant profile: supported versions, service endpoints, capabilities, and payment handlers.

### MCP Endpoint

```
POST https://velasyaromas3.mitiendanube.com/api/ucp/mcp
Content-Type: application/json
```

Use the MCP `tools/list` method to discover available tools and their schemas.

### Typical Agent Flow

1. **Discover** — `GET /.well-known/ucp` to confirm capabilities
2. **Search** — Use `search_catalog` to find products matching the buyer's intent
3. **Cart** — Use `create_cart` to add desired items
4. **Checkout** — Use `create_checkout` to start the purchase flow
5. **Fulfill** — Use `update_checkout` to set shipping address and method
6. **Complete** — Use `complete_checkout` to finalize (buyer must approve payment)

### Supported UCP Versions
- `2026-04-08` (latest stable)
- `2026-01-23`

### Important Rules

- **Checkout requires human approval.** Agents must not complete payment without explicit buyer consent.
- **Respect rate limits.** The MCP endpoint is rate-limited per IP. Back off on 429 responses.
- **Use buyer context.** Pass `context.address_country` and `context.currency` for accurate pricing and availability.


## Read-Only Browsing (No Authentication Required)

For agents that only need to read store data without transacting:

### Product Data
- Browse all products: `GET /productos`
- Product page: `GET /productos/{handle}`
- Category page: `GET /{handle}`
- Search: `GET /search?q={query}`

### Store Metadata
- Sitemap: `GET /sitemap.xml`
- Agent discovery: this document (`/agents.md`) is the canonical agent-facing description of the store.

## Contact
- Contact: 
- Phone: 

## Platform

This store is built on [Tiendanube](https://www.tiendanube.com), the leading commerce platform powering hundreds of thousands of stores in LATAM. Tiendanube stores support UCP natively, enabling seamless agent-driven commerce.

Questions

Can UCP agents buy from velasyaromas3.mitiendanube.com?
Through its REST and MCP services, an agent can search the catalogue, build a cart and start a checkout. The service answered our check. This is what the store declares and what our check reached; an observed agent run shows how far an agent actually gets.
Is velasyaromas3.mitiendanube.com ready for UCP agents?
velasyaromas3.mitiendanube.com publishes a valid UCP profile and scores 95/100 (grade A). Our check found nothing to fix.
What is a UCP profile?
The JSON file a store publishes at /.well-known/ucp to tell UCP agents which services it offers, how to call them and how it takes payment. The spec calls it the business profile. velasyaromas3.mitiendanube.com's is 4.0 KB, written for UCP 2026-08-25. What goes in a UCP profile.
How was velasyaromas3.mitiendanube.com checked?
With public requests on 6 Nov 2026: we read /.well-known/ucp and robots.txt, validated the profile against UCP 2026-08-25, checked that its spec and schema links resolve, and called its REST and MCP service. No sign-in and no purchase. How we check.
