How I Built an Open-Source MCP Server for E-Commerce (And What I Learned)

I've always had this gut feeling that AI-to-AI communication would eventually become the norm — machines talking to machines on behalf of humans. But for the longest time, I had no idea how to actually get there. From vibe coding to a real product problem I'm a solo fullstack developer who builds with AI. Not just uses AI — builds with it. Vibe coding is incredible: you can prototype, ship, and iterate faster than ever before. With a product background and neural networks as my co-pilot, I've been shipping projects solo that would have required a team just two years ago. At some point, I had an idea: what if I could build a SaaS that generates an AI chat widget for any small or mid-sized business in about 10 minutes, just by feeding it the website's content? So I built it. And then I realized — there are dozens of tools like this. The difference isn't the widget. The difference is specificity. The moment everything clicked My first real client was a store I had previously built a Next.
