Has anyone used Claude as a training and diet coach with real wearable data?

I want Claude to act as my personal coach: read my health data (sleep, heart rate, steps, workouts) and adjust my training and diet plans based on it. My setup: two watches (CMF Watch from Nothing for workouts, a Timberland watch for daily wear) plus my phone, all syncing to Health Connect on Android 16. I have a home lab and a VPS, so I’m thinking of building a small pipeline: Health Connect → my own server → a custom MCP connector so Claude can query the data when I ask. Before I build anything: Has anyone connected wearable or Health Connect data to Claude? Which connector or MCP server did you use? Does it actually give useful, adaptive advice, or does it get generic after a while? How do you handle memory across conversations, so Claude keeps track of the plan and progress over weeks? Projects, a skill, something else? Any concerns about sharing health data this way, and how did you deal with them? Genuine question about my own setup, not promoting anything. Refined this idea in a conversation with Claude and used it to help structure and write the post in English (I’m Portuguese).
