Building an MCP Server to Let Claude Read My Blood Sugar
2 January 2026
I started wearing a continuous glucose monitor, and within weeks I'd accumulated over 150,000 data points.
The data was interesting. The problem was accessing it. I wanted to actually interrogate my data - correlate glucose spikes with meals, compare patterns across weeks, ask questions I hadn't thought of yet.
So I built an MCP server that lets Claude query my blood sugar directly. Now I can ask "what was my average reading last week?" or "when do I typically see spikes?" and get real answers from my own data.
The code is open source and surprisingly simple - about 100 lines of Python.
