Overview

AI-generated overview

Lets an assistant match a German shopping list to current store offers and plan an optimal multi-stop shopping route.

What you can do
It offers two tools. plan_optimal_shopping_route matches each item on a list to current offers across German supermarkets and drug stores such as REWE and Aldi, plans a multi-stop route from a starting location, and gives a worth-it verdict. swap_route_item replaces one item's chosen offer on an existing route with an alternative and returns the recomputed route with corrected costs.
When to use it
Use it when someone already has a German grocery and drugstore shopping list and wants to know which stores to visit and whether the trip is worth it, or to correct a poor pick on an existing route.
Requirements
A remote endpoint connection with network access; no environment variables, headers or authentication are declared.
Before you install
Routes and costs depend on third-party live offer data that can change at any time; treat the plan as guidance and confirm actual prices and stock with the stores.

Installation

In SourceWeft

  1. Open offerhopper.ai — AI Supermarket & Drugstore Shopping Assistant for Germany in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/ai.offerhopper.mcp%2Fgerman-grocery-assistant/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

plan_optimal_shopping_route

Plan optimal grocery and drug store shopping trip

Plans the optimal shopping trip for a given list and starting location in Germany. Answers 'where should I go to buy this list, and is the trip worth it?' — not 'what's on offer near me'. Matches each item on the list to the best current offer across German supermarkets and drug stores (REWE, Aldi, Lidl, Penny, Netto, Norma, Edeka, DM, Rossmann, Mueller, Globus), then computes the cheapest realistic route by weighing product prices against travel distance and shopping time. Returns the chosen store(s), the per-item picks with live prices, the trip's savings and a worth-it Supports car, bicycle, and pedestrian travel modes. For corridor trips (A-to-B), supply 'end_location' to route stores along the way. Pricing note: 'price' is the standard shelf price available to all shoppers (do NOT say discounts require an app). 'app_credit' is optional wallet cashback (e.g. REWE Bonus: plus €0.50 into wallet). 'app_price' is an app-exclusive checkout price (e.g. Lidl Plus).

swap_route_item

Swap an item on a shopping route

Swaps one item's chosen offer on an existing shopping route (from a prior plan_optimal_shopping_route result) for one of its alternatives, then returns the RECOMPUTED route with corrected costs and the honest worth-it verdict. Use this to correct a poor pick (e.g. the engine matched a soup hen instead of a roasting chicken) or to take a cheaper/better option the agent spotted in the item's 'alternatives'. The alternative may be at the SAME store or at ANOTHER store ALREADY ON THE ROUTE — it must be the same item category, and its store must already be a stop (no new stores; for that, call plan_optimal_shopping_route again). Keys on stable offer ids: pass the current item's offer_id and the target alternative's offer_id (both taken verbatim from the prior response's products_to_buy / alternatives). The shared route (share_url) is updated in place so the interactive map reflects the swap.
