TilbudsTrolden

The deal troll that lives under the bridge between your fridge and your wallet.

An MCP server for Nordic grocery shopping. It finds the best deals across supermarkets in Denmark, Norway, Sweden, and Finland, plans your weekly dinners around what's cheap, and builds shopping lists grouped by store. You talk to your AI assistant about dinner; the troll does the legwork.

Works with any MCP-compatible client: Claude Desktop, Claude Code, VS Code, Cursor, Windsurf, ChatGPT, and others.

Features

Deal search

Search current deals across grocery chains in Denmark, Norway, Sweden, and Finland. Compare unit prices (kr/kg for Scandinavian kroner, €/kg for Finnish euros) side by side. Check what's on offer at a specific store, or get a combined view from all your preferred stores at once.

Recipe library

Ships with 32 starter recipes (Danish households) spanning Danish, Italian, Asian, Mexican, and Swedish cuisines. Deals are matched to ingredients automatically. Add your own recipes in your local language, remove ones you don't like, or tweak the defaults. Norwegian, Swedish, and Finnish households start with a clean slate for adding recipes with local search terms.

Meal planning

Plan your week's dinners. The planner checks current deals, picks the cheapest combination of recipes, and makes sure you're not eating chicken four nights in a row. You set the rules: no pork, slow-cook only on weekends, at least 3 Asian dishes this week. It handles the rest.

Shopping lists

Get a shopping list from any set of recipes. Shared ingredients are added up across recipes (8 carrots, not "2 for this + 3 for that + 3 for the other"). Pantry items are excluded. Current deals are matched per ingredient and grouped by store.

Household config

Tell the assistant which country you're in (DK, NO, SE, or FI), how many people you're cooking for, which stores you prefer, and any dietary restrictions. Everything else follows from that: deals from your stores rank higher, pork disappears if you said no pork, and shopping lists scale to your household. Country defaults to Denmark if not set.

Pantry tracking

Tell the assistant what you already have at home. Those items get skipped in shopping lists, so you don't come home with a third bottle of soy sauce.

Meal and spend logging

Record what you cooked and what you spent. The planner keeps track so you don't end up eating lasagne every Tuesday.

Example conversations

Real examples of how you'd talk to your AI assistant with TilbudsTrolden running.

Set up your household

You: We're 3 people, no pork, and we shop at Netto, REMA 1000, and Meny.

The assistant saves your setup. From now on, deals from Netto, REMA, and Meny get priority, and pork recipes are excluded from meal plans.

You: Switch me to Finland. We shop at Prisma, K-Supermarket, and Lidl.

Country becomes FI, stores update, and deals now come from Finnish chains. Prices show in €/kg instead of kr/kg.

Check deals

You: What's on sale at my stores this week?

You get a summary per store: expiring deals that need action, biggest savings, and highlights.

You: Find me the cheapest hakket oksekoed.

Found 6 deals for "hakket oksekød":
1. Hakket okse- eller grisekød - 99 DKK (76.15 kr/kg) @ Bilka
2. Hakket oksekød 8-12% - 36.66 DKK (91.65 kr/kg) @ Fleggaard
3. Velsmag hakket oksekød 7-10% - 45 DKK (112.50 kr/kg) @ Netto
...

Plan a full week

You: Plan next week's dinners. No pork except Tuesday, mix of Asian and other.

You get a 7-day plan with no consecutive protein or cuisine repeats, plus a shopping list for the whole week.

Add your own recipe

You: Save a recipe for chicken tikka masala: 500g kyllingebryst, 200g yoghurt, tikka masala paste, hakkede tomater, piskefloede, ris. Medium, Indian, chicken.

The recipe is saved. It shows up in meal plans and deal matching from now on.

Shopping list for specific meals

You: Make a shopping list for bolognese and tacos, 4 people.

Shared ingredients (like onions used in both) are aggregated. Pantry items are excluded.

Track pantry

These items get skipped in future shopping lists.

Log what you cooked

You: We made the bulgogi tonight, spent 185 kr at REMA.

How deal matching works

Nordic grocery deals bundle products in creative ways ("Rejer, kold- eller varmroget laks"). TilbudsTrolden tells raw ingredients apart from processed products using language-specific food terminology for Danish, Norwegian, Swedish, and Finnish. Searching for "laks" as a cooking ingredient won't match roget/rokt/rokt laks or palaeg/palegg/palagg, and searching for "jauheliha" in Finland won't match savustettu makkara. Your preferred stores get priority in results.

The scoring engine uses locale-specific indicators for each country: processed meat terms (roget/rokt/rokt/savustettu), raw meat terms (fersk/fersk/farsk/tuore), non-food filters, and dietary exclusion patterns. All four languages have full coverage for pork, beef, lamb, fish, shellfish, dairy, gluten, beans, nuts, and egg exclusions.

The meal planner won't repeat the same protein or cuisine more than twice in a week, and you can restrict slow-cook recipes to specific days.

Data storage

All data lives in a single JSON file: ~/.tilbudstrolden.json. Override the path with the TILBUDSTROLDEN_DATA environment variable.

Everything lives there: household config, recipes, pantry, meal history, and spend log. Created automatically on first use. No database, no cloud service, no account required.
