Packing List MCP

mcp-packing-list

MCP server for packing slips and packing lists: cartons, contents, weights, chargeable weight and what is still to pack. Packing slips that carry no prices: what is in each carton, what it weighs, and what is still to pack.

Works with Claude Desktop, Claude Code, Cursor and any Model Context Protocol client. Runs on your own machine, or hosted with no install.

Product page: https://mcp.zovo.one/s/packing-list — what it does, the tools it exposes, and a live token endpoint.

Install

Hosted, nothing to install. Get a token from https://mcp.zovo.one/mcp/connect (the connect page) or https://mcp.zovo.one/mcp/token (the same token as JSON); a free anonymous one is issued on the spot and a Pro key works the same way. Then point an MCP client at https://mcp.zovo.one/mcp/packing-list over streamable-http and send the token as Authorization: Bearer <token>.

If your client cannot set headers, put the token in the path instead: https://mcp.zovo.one/mcp/packing-list/t/<token>. Both forms work. The bare URL with no token answers 401 on tools/call, so the token is not optional.

Claude Desktop, one click. Download packing-list.mcpb from the latest release and double-click it.

From source. The mirror is self-contained: every @theluckystrike/* dependency is vendored, so a fresh clone builds with no extra setup.

git clone https://github.com/theluckystrike/mcp-packing-list.git
cd mcp-packing-list
npm install && npm run build

Then point your client at the built entry point:

{
  "mcpServers": {
    "packing-list": {
      "command": "node",
      "args": ["/absolute/path/to/mcp-packing-list/dist/index.js"]
    }
  }
}

@theluckystrike/mcp-packing-list is not published on npm yet, so an npx -y @theluckystrike/mcp-packing-list command will fail. The three paths above are the working ones and each is exercised by CI.

In the official MCP Registry (io.github.theluckystrike/packing-list). The packing slip for a shipment, and the answer to the only two questions anybody asks while packing one: what is in which box, and what is still to pack. A packing list is raised against an order you name, the lines that order says should ship are declared on it, cartons are added with a tare weight and their outside dimensions, and goods go into cartons one call at a time. packing_shortfall then reports every line as short, complete, over-packed, or packed and not on the order at all. carton_report gives the tare, net, gross, volume, volumetric and chargeable weight per carton and for the shipment.

That is not a simplification, it is what the document is for: it travels inside the box, and the consignee's warehouse is not the party that sees what the goods cost. The invoice against the same order is a different document and lives in @theluckystrike/mcp-invoice. There is no money arithmetic in this server at all, and a test asserts there is not.

Mass is in whole grams everywhere and dimensions in whole centimetres, for the same reason money is in minor units: a kilogram carried as a float accumulates error over a hundred lines and then disagrees with the carrier's scale.

Nothing derived is stored. A record holds its cartons, its declared order lines and its packed lines; every weight and the whole shortfall are computed on the call. A stored gross weight is a second copy of what the lines already say, and it is the copy that gets believed after somebody unpacks a line.

The chargeable weight, which is the number that costs money

Couriers bill the greater of what a box weighs and what its volume is worth. The volumetric weight is length x width x height / divisor, in centimetres, and the divisor is a tariff term: 5000 cm3/kg is the courier air default, 6000 the older IATA air figure, 4000 appears on some road tariffs. It is a parameter on every tool that reports it and never a constant inside a formula, because a chargeable weight computed against the wrong divisor is a carrier invoice nobody catches until the account is reconciled.

Two refusals matter here and both are deliberate:

• A carton with only two of its three dimensions is refused outright. Two of three cannot make a volume, and a partially measured box would drop silently out of the shipment total.
• If any carton has no dimensions at all, the shipment's volumetric and chargeable totals come back as null, never as a total that quietly skipped three boxes.

npm publish for @theluckystrike/mcp-packing-list is pending, so the npx line below returns 404 today. Build from source in the meantime; see llms-install.md.

Tools

Tool	What it does
packing_list_create	Open a packing list against an order: the reference, the consignee, where it ships to, the date
packing_expect	Declare an ordered line, so the shortfall is real. Nothing is read from the quotes, work-order or invoice store
carton_add	Add a carton: a label, the empty weight in whole grams, and all three outside dimensions or none
pack_item	Put a quantity of one item into a named carton, with the per-unit weight in whole grams
unpack_item	Take a packed line back out by its L01-style id. Deleted, not zeroed
packing_list_show	The whole list: cartons with contents and weights, the ordered lines, the shortfall, and whether it is ready to ship
packing_list_list	Packing lists newest first, filtered by status, order reference or consignee
carton_report	Tare, net, gross, volume, volumetric and chargeable weight, per carton and for the shipment
packing_shortfall	Ordered against packed: what is short, what is over-packed, what is not on the order
packing_list_status	draft to packed to shipped, or cancelled. Shipping records the carrier and tracking, and freezes the list
packing_slip	The slip as text on every tier. Pro also writes it to out_path as a .txt file
packing_list_delete	Delete a list for good. A shipped list is refused: it is the record of what left the building
license_status	Which tier this install is on and where the key came from
license_activate	Store a Pro key for this server

There is also a resource, packinglist://contract, carrying the status machine, the weight basis, what each shortfall state means, the free-tier limits and the one directory this server writes; and a prompt, pack_the_shipment, that walks the whole job in order.

Free vs Pro

	Free	Pro
Open packing lists at once	3	unlimited
Cartons, packed lines, ordered lines	unlimited	unlimited
carton_report, packing_shortfall, packing_list_show	yes	yes
The packing slip as text	yes	yes
Writing the slip to a file with out_path	no	yes

The cap is on shipments in flight, not on knowing what is in a box. Marking a list shipped or cancelling it frees its slot, and so does deleting a draft, so a free user can always get back under the limit without a key.

Privacy

All data stays local, in ${XDG_DATA_HOME:-~/.local/share}/mcp-servers/packing-list/. There is no network call anywhere in this server, no API key, and no account. The only file it reads that it does not own is the shared business profile, for the name and address at the top of the slip, and it never writes to it.
