## 1. Agent Commerce Instructions

### 1.1 Universal Commerce Protocol (UCP)

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

**Endpoints:**
| Purpose | Method & Path |
|---|---|
| Discovery | `GET https://barkeepersfriend.com/.well-known/ucp` — returns supported versions, service endpoints, capabilities, and payment handlers |
| MCP endpoint | `POST https://barkeepersfriend.com/api/ucp/mcp` (`Content-Type: application/json`) — use MCP `tools/list` to discover available tools and schemas |

**Supported UCP versions:** `2026-04-08` (latest stable), `2026-01-23`

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

**Important rules:**
- **Checkout requires human approval.** Agents must not complete payment without explicit, contemporaneous buyer consent at the moment of payment.
- **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.

### 1.2 Read-Only Browsing (No Authentication Required)

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

| Data | Path |
|---|---|
| Browse all products | `GET /collections/all` |
| Product page | `GET /products/{handle}` |
| Product JSON | `GET /products/{handle}.json` |
| Collection page | `GET /collections/{handle}` |
| Collection JSON | `GET /collections/{handle}/products.json` |
| Search | `GET /search?q={query}&type=product` |
| Sitemap | `GET /sitemap.xml` |

### 1.3 Platform

This store is built on [Shopify](https://www.shopify.com). Shopify stores support UCP natively, enabling agent-driven commerce.
