Wellness Cgm Mcp

davidmosiah/wellness-cgm-mcp

Plugs Dexcom Developer API and FreeStyle Libre (via LibreLink Up) into Claude as an MCP server. Exposes 19 tools for reading glucose values, calculating time-in-range stats, detecting hypo events, and analyzing meal response curves. Ships with synthetic mock data by default so you can prototype without credentials. When configured, it pulls live CGM readings and computes ADA-standard metrics like GMI, coefficient of variation, and two TIR profiles (diabetic 70-180 and metabolic health 70-140). The meal response tool is designed to pair with food logging MCPs to close the "what I ate and what happened" loop. Built as the free local alternative to $199/month subscription CGM coaching apps.
