>>MCP Affiliate Shopping Engines

As someone else once said, I want a Grocery Shopping Engine. "Here's my shopping list, taking into consideration delivery times and costs, please buy this for the lowest cost from any combination of supermarkets and deliver by day after tomorrow at the latest."

If MCPs gave the LLMs a window into all the major supermarkets home shopping sites that looks like it's a step closer.

This requires arithmetics and constraint solving skills that are wildly out of reach to any pure-LLM platform. At the very least you would need interfacing with a real SMT or LP solver to get something that fits the bill.

And how exactly will they do that?

  • There are existing comparison services that keep track of prices and locations of grocery items. MCP is just the glue code.

  • Not OP but perhaps the following mcp tools: google maps api, nearest supermarkets, puppeteer their product listing pages?

    Though to be honest not sure why you would need so much info - if I need lettuce or tomatoes for example, I know theyre gonna be at essentially every supermarket in my area....

    • In the UK, most supermarkets offer their own home delivery services.

      I was hoping that an LLM would do the heavy lifting of working out who can get your shopping cheapest from various supermarkets.

      Probably not worth it if you're buying lettuce and tomatoes, but if you have a large family with a £100+ grocery bill per week it might be worth it?
