Packrift MCP Server (`io.github.Packrift/packrift-mcp`)

This hosted no-auth Model Context Protocol (MCP) server supports exact-spec packaging procurement. It is designed to search packaging by item, SKU, or reorder need, then confirm live price, inventory, shipping, and provide a cart handoff workflow with no-match handling.

🛠️ Key Features

Hosted MCP server with no-auth access
Exact-spec packaging search, live price, stock, and shipping confirmation
Cart handoff and “no-match” behavior
MCP endpoints: POST /mcp, GET /mcp (SSE), plus GET /, GET /start, and GET /.well-known/mcp/server-card.json
Implementation stack: Cloudflare Workers, TypeScript (strict), Hono, Zod, Streamable HTTP transport
Tooling: 15 tools

🚀 Use Cases

Find packaging supply for a given item, SKU, or reorder need
Re-check current procurement details before proceeding to checkout
Handle cases where no exact match is found

⚡ Developer Benefits

Standard MCP integration via POST /mcp and SSE at GET /mcp
Server-card discovery at /.well-known/mcp/server-card.json
Shopify backing via Admin GraphQL API (2025-04) on packrift.myshopify.com

⚠️ Limitations

No-auth deployment (access is not authenticated)
Behavior depends on Shopify Admin GraphQL data availability and the server’s exact-spec matching rules

Tools

Tool	What it does
`search_products`	Search by product type, exact size or spec, or SKU. Returns live price, pack size, price per unit, stock and a product link; close sizes are labeled as not exact.
`find_packaging_for_item`	Give an item's length, width, height, weight and what it is; get boxes or mailers that fit, with cushioning, box strength and billable shipping weight.
`get_product`	Specs, pack count, live price and stock, whether a quantity can ship now, volume pricing and nearby sizes for one SKU.
`get_shipping_estimate`	Delivered cost to a US ZIP code, using checkout rates with automatic volume discounts and free-shipping rules applied.
`create_cart_url`	A packrift.com checkout link for the chosen SKUs and quantities. The buyer reviews and pays on packrift.com.
`get_bulk_quote_link`	A pre-filled quote request for pallet quantities, custom sizes, printing or freight.

Every tool is read-only (readOnlyHint: true, destructiveHint: false) and never places an order or takes payment. Each returns a short text answer plus a compact structuredContent object; pass response_format: "detailed" for the full catalog record.

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.

bash

npm install
npm test                 # offline unit tests and public-surface checks
npm run check:directory-surface
npx wrangler dev         # local worker; set SHOPIFY_PACKRIFT_TOKEN for live tool calls

scripts/v1-live-smoke.mjs exercises every tool against the live store with read-only calls; set SHOPIFY_PACKRIFT_TOKEN before running it.
