Overview

AI-generated overview

Remote Packrift server that lets an assistant search, size, price and prepare checkout links for shipping boxes, mailers, bags and tape.

What you can do
Search the in-stock packaging catalog by product type, exact size, spec or SKU, with live price, pack size and stock, and fetch full specs for one SKU including volume pricing and nearby sizes. Recommend a box or mailer for an item from its dimensions, weight and type, applying cushioning and box strength rules. Estimate delivered cost to a US ZIP code with volume discounts and free-shipping rules. Build a packrift.com checkout link for chosen SKUs and quantities, and get a pre-filled bulk quote request link for pallet, custom, printed or freight orders.
When to use it
Useful when someone is packing or shipping goods and wants help choosing the right box or mailer, comparing per-unit prices, estimating delivered cost, or preparing a checkout or bulk quote without leaving the assistant.
Requirements
A remote Streamable HTTP endpoint; no authentication, environment variables or headers are declared. Shipping estimates need a US ZIP code. Prices, stock and rates are fetched live from Packrift's store, so network access is required.
Before you install
Every tool is described as read-only and never places an order or takes payment; the buyer reviews and pays on packrift.com. Checkout links and quote links carry the chosen SKUs, quantities and any delivery ZIP or need-by date supplied. The server keeps usage records such as tool, time, search text and SKUs returned for up to 90 days. Estimates exclude tax, and checkout shows the final amount.

Installation

In SourceWeft

  1. Open Packrift MCP in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.github.Packrift%2Fpackrift-mcp/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

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.

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

search_products

Search Packrift packaging

Search Packrift's in-stock packaging catalog: corrugated shipping boxes, mailer boxes, poly and bubble mailers, poly bags, labels, packing tape, stretch film and void fill. The query can be a product type, an exact size or spec ("12x12x12 ECT-32 box", "10x13 poly mailer", "3 inch packing tape"), or a Packrift SKU. Returns up to 10 matches with live price, pack size, price per unit, stock and a product link. A different size is never labeled exact; when nothing matches exactly it returns the closest sizes marked as not exact and a quote link. If the buyer describes the item they are shipping rather than the packaging they want, use find_packaging_for_item instead.

Parameterslimitqueryrequiredresponse_format

find_packaging_for_item

Find packaging that fits an item

Find the right Packrift box or mailer for an item the buyer ships. Give the item's length, width and height in inches, its weight, and what it is (for example "ceramic mug", "t-shirt", "hardcover book", "laptop"). Applies cushioning space by item type (2 in per side for fragile items), checks box strength against the weight, and compares billable shipping weight (UPS/FedEx and USPS dimensional weight). Returns up to 5 in-stock options with inside size, fit, strength, live price and a product link. Use search_products instead when the buyer already knows the packaging size they want.

get_product

Get Packrift product details

Get one Packrift product by SKU (or product handle): specs such as inside size, material, strength and pack count, live price and price per unit, stock, whether a quantity can ship now, volume pricing, nearby sizes and the product link. Use after search_products or find_packaging_for_item when the buyer wants more detail before choosing.

Parametersskuhandlequantityresponse_format

get_shipping_estimate

Estimate delivered cost of a Packrift order

Estimate the delivered cost of a Packrift order to a US ZIP code, using the same shipping rates and automatic volume discounts as Packrift checkout. Give the items as SKU and quantity (number of packs). Returns the subtotal after discounts, the shipping charge (free only when the order qualifies), the delivered total and the delivered cost per unit. Tax is not included; checkout shows the final amount. Not for carrier rate shopping or postage.

create_cart_url

Create Packrift checkout link

Create a checkout link on packrift.com for items the buyer has chosen. Give each item as SKU and quantity (number of packs); up to 25 lines. The link opens packrift.com checkout with those items and automatic volume discounts applied; the buyer adds their address and pays there. Returns the subtotal after volume discounts. This tool never places an order or charges anyone. Call it only after the buyer confirms the items and quantities.
