I Replaced MyFitnessPal and Other Apps With a Single MCP Server: Here's How I Did It

My doctor asked me to keep a food diary. I tried MyFitnessPal, Lifesum, and others — none of them could easily export a summary for a date range. So I vibe-coded a remote MCP server in one evening using Claude Code. Now I just snap a photo of my food, send it to Claude, and it logs everything with calories and macros. When I need a report, I ask for it in conversation. No app, no manual entry — just a database and a chat.
