Try asking

• "What box should I use to ship a ceramic mug that's 4.5 x 3.5 x 4 inches?"
• "Find 12x12x12 shipping boxes and show me the cheapest per box."
• "I need poly mailers for folded t-shirts. What size, and what would 500 cost delivered to 75201?"
• "Price 10 packs of Packrift SKU 1066 delivered to 10001, then give me a checkout link."
• "I need 2,000 printed 18x12x12 boxes. How do I get a quote?"

How it works

• Live data. Prices, stock and shipping rates come from Packrift's Shopify store at request time.
• Fit. Inside dimensions plus cushioning by item type (about 1/2 in per side for sturdy items, 1 to 2 in for electronics, 2 in for fragile items), box strength by ECT rating against the item's weight, flat-mailer and tube fits, and billable weight including the packaging (UPS and FedEx divide by 139; USPS also divides by 139 since July 12, 2026, but only above one cubic foot).
• Delivered price. Checkout shipping rates with automatic volume discounts and free-shipping thresholds applied. Tax is excluded; checkout shows the final amount.
• Checkout. create_cart_url returns a https://mcp.packrift.com/c/... link that opens packrift.com checkout with the chosen items and automatic volume discounts; it also returns the discounted subtotal.
• Exact matches only. A different size, strength, thickness or pack count is never presented as an exact match.
• Resources and prompts. resources/list offers a packaging guide, an overview of Packrift, tool guidance, setup and the privacy notice. prompts/list offers five starter prompts.

Earlier tool names from 0.x (get_pricing, check_inventory, compare_alternatives, pack_calculator and others) remain callable for existing integrations but are no longer listed.

Privacy

The server receives only the arguments your assistant sends to its tools. It keeps usage records (tool, time, search text, SKUs returned, assistant type) for up to 90 days and does not store names, email addresses, phone numbers, street addresses or IP addresses from MCP requests. Full notice: https://mcp.packrift.com/privacy.

Development

The server is a Cloudflare Worker (TypeScript, Hono, Zod) backed by the Shopify Admin GraphQL API.
