Kubova guide: from sign-up to AI integration
Everything you need to go from zero to a finished container load plan — create an account, run your first 3D calculation, read and export the result, and connect Kubova to your AI assistant.
What Kubova does
Kubova turns a list of boxes and a container into an optimized, true-to-scale 3D loading plan. You tell it what you're shipping and which container you're using; it works out how many units fit, the best way to arrange and stack them, and always respects real limits — weight, stacking height, and door clearance. No overflow tricks: what it shows is what genuinely fits. This guide walks you through it end to end.
1Create your account
You can try the calculator without an account, but signing up lets you save load plans, export PDFs, and use the API. It's free to start.
- Open kubova.com and click Get started (top right).
- Enter your email and a password, then submit.
- Check your inbox for the confirmation email and click the link to verify.
- You're in — you'll land on your dashboard.
Create an account 2Run your first calculation
From the dashboard or the top menu, open the Calculator. The wizard takes you through a few short steps:
- Add your cargo: enter the box's length, width and height (in cm), its weight (kg), and how many you're shipping. Give it a name and color so it's easy to spot in 3D.
- Set stacking and rotation rules: allow the box to be stacked on and rotated, unless your cargo can't be (for example, 'this side up' goods).
- Pick a container: 20ft, 40ft, 40HC, or define your own custom dimensions.
- Click Calculate — the plan is ready in seconds.


Tip: dimensions are the size of each carton, not the pallet.
3Read the 3D result
The result screen shows an interactive 3D model of the loaded container plus the key numbers:

- Drag to rotate, scroll to zoom, and inspect exactly where each unit sits.
- Units loaded: how many of your cartons actually fit.
- Volume utilization: how much of the container's space is used.
- Weight: total loaded weight against the container's payload limit.
- If some units don't fit, Kubova tells you how many are left over so you can decide on a second container or a different setup.

4Load mixed products (multiple SKUs)
Shipping different box sizes together? Add each one as a separate cargo item before calculating. Kubova packs them as a single combined load — which usually fits more than planning each product on its own. This is where it beats simple single-product calculators.
5Save and export your load plan
Once you're happy with a plan:
- Click Save to keep it in your dashboard under Saved packs.
- Click Download PDF for a clean, printable load plan — 3D views, the unit count, utilization and weight — ready to share with your team or freight forwarder.
- Reopen any saved pack later to review or re-export it.
6Estimate capacity (how many fit)
Need the reverse question — 'how many complete sets of my product fit in one container?' Use the Capacity tool. Enter the cartons that make up one set and a container; Kubova returns how many full sets fit with real 3D packing, and tells you whether space or weight is the limiting factor.

7Connect Kubova to your AI assistant (MCP)
Kubova ships an MCP server, so AI assistants like Claude, ChatGPT and Cursor can plan container loads for you in plain language. There are two ways to connect.
Skip the data entry — just send a photo or file
This is the real time-saver. Inside the chat you don't have to type a single number. Drop in a photo of your packing list, a spec sheet (PDF), or a spreadsheet of carton sizes and quantities — the AI reads the dimensions and counts straight from it, calls Kubova, and hands back the 3D load plan. You describe the goal; the AI does the data entry and the packing for you.

Option A — Connect by URL (no install)
The easiest way. Add Kubova as a remote connector with a single URL; your AI client opens a secure sign-in to your Kubova account — no API key, no terminal.
Connector URL:
https://kubova.com/mcp- Claude (claude.ai / Desktop): Settings → Connectors → Add custom connector → paste the URL.
- ChatGPT: Settings → Apps & Connectors → enable Developer mode → Create → paste the URL.
- Cursor / VS Code: add the URL as a remote MCP server and sign in when prompted.
Option B — Local install (npm)
Prefer a local server (offline config, CI, automation tools)? Get an API key from your dashboard, then add this to your MCP client's config file:
{
"mcpServers": {
"kubova": {
"command": "npx",
"args": ["-y", "@kubova/mcp@latest"],
"env": {
"KUBOVA_API_KEY": "kbv_..."
}
}
}
}Claude Desktop: claude_desktop_config.json · Cursor: ~/.cursor/mcp.json · Claude Code: ~/.claude/settings.json
Then restart your client and just ask, for example: 'Pack 20 boxes of 50×40×30 cm into a 40HC container — what's the utilization?' The assistant calls Kubova, packs the load, and explains the result.
The MCP server is open source on GitHub: Kubova-com/kubova-mcp.
8Automate with the REST API
For your own apps and scripts, the same engine is available over a REST API — pack, capacity and PDF report endpoints, authenticated with an API key. See the API reference for request and response formats.
Read the API referenceCommon questions
Is it free?
You can run calculations and see 3D results for free. Saving unlimited plans, PDF export at scale, the API and MCP packing are part of the paid plans, which include a 14-day trial.
Do I need to install anything?
No. The calculator runs in your browser. Connecting MCP by URL also needs no install; only the optional local MCP server uses an npm package.
What units does it use?
Dimensions are in centimeters and weight in kilograms by default. You can switch unit systems in your account settings.
Can it handle different boxes in one container?
Yes — add each box type as a separate item and Kubova packs them together as one mixed load.
