I launched a SaaS product called QRflows — a dynamic QR code platform. Two months in, I decided to build an MCP (Model Context Protocol) server for it. Now Claude can create, update, and track QR codes directly from a chat conversation, without touching a dashboard.
This post is about why I built it, how it works technically, and what I learned along the way.
What is MCP and why did I care
MCP is Anthropic's open protocol that lets AI assistants like Claude connect to external services. Think of it like a USB standard — any MCP-compatible server can plug into Claude and give it new tools.
For QRflows, this meant Claude could become a QR code manager. A user types "create a QR code for my restaurant menu that routes to the breakfast version before 11am and the dinner version after" — and it just happens.
