Your meals, workouts, and habits — tracked by talking, not tapping. bios is an MCP server that gives Claude memory of your body. No forms, no dashboards, no calorie database to search. Say "chicken tikka, around 65g protein" — Claude estimates, confirms, logs. Ask "how's my week?" — real answer, not a chart. Tracks meals, workouts, supplements, sleep, mood — anything. Runs on Cloudflare Workers + D1. Self-hostable in 5 minutes; free tier covers solo use indefinitely.
