Packing slips that carry no prices: what is in each carton, what it weighs, and what is still to pack. You raise a packing list against an order you name, declare what the order says is in it, and pack goods into named cartons one line at a time with a per-unit weight, each carton carrying a tare weight in whole grams and its outside dimensions in whole centimetres. packing_shortfall reports every line as short, complete, over-packed, or packed and not on the order at all, matched on SKU where there is one and on the description where there is not. carton_report gives tare, net, gross, volume, volumetric and chargeable weight per carton and for the whole shipment at a divisor of 4000, 5000 or 6000 cm3 per kg, because the divisor is a tariff term, not a constant. The slip itself carries no prices at all: the invoice against the same order is a different document, and no currency symbol reaches the rendered slip. Nothing derived is stored.
The packing lists live in the hosted store behind the token, so the three free open lists and the PL-YYYY-NNNN numbers follow the key rather than the machine. There is no network call inside the server on any route, so the carton arithmetic is the same here as on a laptop: mass in whole grams and dimensions in whole centimetres, the chargeable weight the greater of gross and volumetric at the divisor you name, and the slip carrying no prices at all. packing_slip's text comes back in the answer on every tier, and the Pro out_path form is a one-hour download link rather than a path.
| You say | Tool |
|---|---|
| Open a packing list against WO-2026-0044 for Harbour Cafe, shipping to 12 Dock Road, Bristol. | packing_list_create |
| Box 1 is 40 by 30 by 25, tare 800 grams: eight shelves at 1250 grams and all twenty-four brackets at 150. | carton_add then line_pack |
| What will DHL charge me for at their 5000 divisor? | carton_report |
On the worked shipment the chargeable weight is 20.000 kg at divisor 5000 and 20.400 kg at 4000, and only the second carton changes basis. A server that hardcoded 5000 would have under-billed that shipment by 400 g and nobody would have found it until the carrier's account was reconciled. The unit suite asserts that no currency symbol reaches the rendered slip, because a packing slip is the one document in this estate that must not carry money.
https://mcp.zovo.one/mcp/connect mints an anonymous token and prints a URL per server, including this one, shaped like https://mcp.zovo.one/mcp/packing-list/t/<token>. That URL works with no headers: the token is in the path, not in an Authorization field this form does not have.
Idle anonymous tokens are swept after 30 days. Since this route has no filesystem, a file MCP Packing List generates comes back as a download link that expires after one hour. A Pro key can replace the token in the same URL and removes the free-tier limits.
On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.
Free: Three open packing lists, draft and packed, with unlimited cartons, packed lines and declared order lines on every tier. The cap counts shipments in flight rather than shipments ever made, so marking one shipped or cancelling it frees its slot, and deleting a draft is free on every tier. Every text answer, including the packing slip itself, is free. Pro is $19 once, verified offline, and binds to the token after checkout.
No. Add custom connector offers an Advanced settings section with an OAuth Client ID and Client Secret, but the connect-by-URL route does not use it. Leave both blank: the token in the URL path is what authenticates.
That is documented, not a bug: on Team and Enterprise, only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, Add, Custom, Web. After that, members connect to the URL the Owner added from Customize, Connectors.
Yes. The token segment of the URL from /mcp/connect can be replaced with a Pro key, which removes the free-tier limits on MCP Packing List for that connector.
The connector runs server-side with no filesystem of its own, so any file MCP Packing List produces is handed back as a download link that expires after one hour, rather than a path on disk.
