I Built an MCP Server for Vinted. Here's How Cross-Border Price Gaps Make You Money

I was browsing Vinted France and saw Nike Air Force 1s for €45. Out of curiosity, I checked the same shoe on Vinted Germany. €89. Almost double. That's when I realized: Vinted isn't one marketplace. It's 23 separate ones, each with its own pricing universe. And nobody is comparing them. So I built a tool that does. The Problem: 23 Countries, Zero Cross-Border Search Vinted operates in 23 countries. France, Germany, Italy, Spain, Netherlands, Poland, Czech Republic, Lithuania... the list goes on. Each country has its own domain, its own user base, and its own supply and demand dynamics. Here's the thing: there's no way to search across countries. If you're on vinted.fr , you only see French listings. If you're on vinted.de , only German ones. Vinted keeps these markets completely siloed. This creates massive price gaps. And I don't mean 5-10% differences. I mean this: Item Cheapest Country Price Most Expensive Price Spread PS5 Console Poland €285 Netherlands €415 46% iPhone 16 Pro Lithu
