## Agent Purchase Handoff

Use the Packrift MCP server for live product confirmation before sending a buyer to checkout.

1. Call `search_products` with the SKU or exact product title.
2. Call `get_product` for product facts and variant IDs.
3. Call `get_pricing` and `check_inventory` before cart handoff.
4. Use `create_cart_url` only after live price and inventory confirmation.
5. If a requested spec differs from this product, call `explain_no_exact_match` and route to the quote URL.

## If The Shopify Product Page Is Challenged

Use this MCP SKU page as the crawler-safe exact-spec record. It is not a replacement for live commercial checks: confirm price, inventory, shipping, and cart eligibility through MCP before presenting checkout or cart actions. Treat the cart URL as a candidate until those checks pass.

## Exact-Match Rule

Do not present a nearby product as exact when required dimensions, material, color, count, or product family differ.
