An [MCP](https://modelcontextprotocol.io) 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.
## Supported stores
**Denmark:** Netto, Meny, Lidl, REMA 1000, Foetex, Bilka, Spar, Kvickly, 365discount
**Norway:** REMA 1000, KIWI, Meny, Coop Prix, Extra, Bunnpris, Obs, Spar, Joker
**Sweden:** ICA (Maxi/Kvantum/Supermarket/Nara), Willys, Hemkop, City Gross, Coop, Stora Coop, Tempo
**Finland:** S-market, K-Market, K-Supermarket, K-Citymarket, Prisma, Lidl, Tokmanni, Alepa, Sale, Halpahalli, Minimani, Saiturinpörssi
All deal data is fetched via the [etilbudsavis.dk](https://etilbudsavis.dk) (Tjek) API, which serves flyer data for all four countries. Coverage varies; Denmark has the deepest data, followed by Finland, Sweden, and Norway.

## 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.
```
7-day meal plan (3 people)
Mon: Tomatrisotto (Italian, vegetarian)
Tue: Chow Mein (Asian, pork)
Wed: Laks i fad (Danish, fish)
Thu: Maangchi's Bulgogi (Asian, beef)
Fri: Fiskefilet med remoulade (Danish, fish)
Sat: Lasagne (Italian, beef)
Sun: Nudelsuppe med kylling (Asian, chicken)
Shopping list (58 items)
Buy at Netto: hakket oksekød 45 DKK, kyllingebrystfilet 49 DKK, ...
Buy at REMA: oksemørbrad 129.95 DKK, remoulade 10 DKK, ...
Buy at regular price: mozzarella, parmesan, kokosmælk, ...
```
### 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
> **You:** We have rice, soy sauce, and sesame oil at home.
These items get skipped in future shopping lists.
### Log what you cooked
> **You:** We made the bulgogi tonight, spent 185 kr at REMA.
No bulgogi for a while.
## 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.

Scored across 18 tools
Disambiguation5/5
Each tool has a clearly distinct purpose and scope. Even overlapping areas like deals are well-differentiated: deals_this_week shows best deals from preferred stores, search_deals searches across stores by keyword, and get_store_offers shows offers from a specific store. Descriptions include clear USE WHEN / NOT FOR guidance, minimizing ambiguity.
Naming Consistency5/5
All tools follow a consistent verb_noun pattern in snake_case (e.g., add_recipe, get_recipes, log_meal, update_household). Multi-word names like deals_this_week and generate_shopping_list still adhere to the pattern. No mixing of camelCase or other conventions.
Tool Count5/5
18 tools is well-scoped for a meal planning and grocery deal optimization server. It covers all necessary operations (CRUD for recipes, household, pantry; logging for meals and spend; multiple deal query methods; combined planning) without unnecessary redundancy. The number feels appropriate and each tool serves a clear purpose.
Completeness5/5
The tool surface covers the full lifecycle of meal planning based on deals: recipe management, household configuration, pantry tracking, meal history, spend tracking, deal discovery, recipe scoring, shopping list generation, and combined planning. There are no obvious gaps; for example, add_recipe also handles updates, and update_pantry can both add and remove items. The domain is fully addressed.
