I recently built a few MCP servers that let AI assistants search listings, find products, and check prices and availability.

The idea was simple: instead of opening several websites and searching each one manually, I wanted to ask an assistant to find what I was looking for.

So far, I’ve built servers for:

Apple Store : products, configurations, prices, delivery estimates, and pickup availability

MediaMarkt, MediaWorld, and Saturn : product search, store search, and pickup availability

MaxGaming : gaming products, prices, and availability across storefronts

Kleinanzeigen : searching and reading listings

What I learned

MCP gives each server a consistent way to expose tools to an assistant. The more interesting work is figuring out how to get useful data from each site and return it in a form the assistant can work with.

Every site is different.…
