Grand Totalthe whole price, shipping included

Use Grand Total in your AI assistant

Ask Claude, ChatGPT or another assistant for the cheapest way to buy something, or a whole list, delivered, and it asks us. The total, the shipping and the split between shops come from the same optimizer as this site, not from the model's arithmetic.

Every assistant below uses the same address. No account and no API key:

https://grand-total.com/shopping/mcp

Then ask, for example: “Where is wood glue cheapest, delivered to Aarhus?” or “Cheapest delivered: a bike pump, two 28-inch inner tubes and tyre levers.”

Claude

Add to Claude

The button opens Claude's “Add custom connector” with Grand Total filled in; choose “Add”. Then switch Grand Total on in a chat's tools menu. Works on every Claude plan, including Free.

ChatGPT

Our ChatGPT plugin is waiting for OpenAI's review. Until it is listed, add the address by hand:

  1. Open chatgpt.com/plugins, choose + and then “Add custom MCP server”.
  2. Name it Grand Total, paste the address above and choose no authentication.
  3. Start a new chat, add Grand Total from the + menu and ask.

Which ChatGPT plans can add their own servers changes now and then; if you do not see the option, the plugin is the way in once it is listed.

Perplexity, Le Chat and others

  • Perplexity (Pro and up): Plugins → Add custom → Add MCP connector → Remote, paste the address, authentication None.
  • Mistral Le Chat: Connectors → Add Connector → Custom MCP Connector, paste the address.
  • Copilot Studio, Claude Team and Enterprise, ChatGPT Business: your admin can add the address once for everyone in the workspace.
  • The Gemini app lets only US accounts add their own servers so far, so it cannot reach Grand Total from Denmark yet.

The assistants rename their menus now and then. If a step above does not match what you see, look for “connectors”, “apps” or “plugins” in the settings.

What the assistant gets

  • Product search in Danish and English, a shopping list matched line by line, and a product found from a link to a Danish shop.
  • Categories, with the cheapest products in each delivered — for when you know what kind of thing you want but not which one.
  • The cheapest delivered basket, with shipping, free-shipping thresholds and any split between shops worked out — and the shops left out, with the reason.
  • Links to buy. They are our affiliate links, the same as on this site: we may earn a commission if you buy, and it does not change the price or the order. The assistant is asked to tell you so.

What we see

Your assistant sends us the list and the delivery country, and nothing about you: no account, no name, no conversation. The assistant's own company sees your chat under its own terms, not ours.

AI agents in your browser

This site also offers the same tools to agents built into the browser, through WebMCP, a standard Chrome is trying out. When an agent uses them, you see it at the top of the page.
