# Agent Instructions — Rubbery

This document describes how AI agents can interact with Rubbery's online store at .

## About Rubbery

Rubbery is a premium sexual wellness brand. Ultra thin condoms, discreet EU delivery, minimal design. One product, done properly. See `/llms.txt` for full product details, pricing, and FAQ.

## Commerce Protocol (UCP)

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

### Discovery

```
GET /.well-known/ucp
```

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

### MCP Endpoint

The MCP endpoint is served on the store's **canonical Shopify domain**, not the
custom domain. Read the authoritative URL from the `mcp` transport `endpoint` in the
UCP profile above (`GET /.well-known/ucp`). It is currently:

```
POST https:///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.
