lets see how this goes

I use Claude for a lot, but it could never see my own health data. I track workouts, sleep, and an Oura ring, and getting any of that into a conversation meant screenshots or copy-paste. None of the device makers ship an MCP server, and the community ones are self-host projects I did not want to maintain.

What worked was a hosted MCP connector. I connect my devices once on the web, then in Claude it is Settings, Connectors, Add custom connector, paste a URL, authorize, and from then on Claude can answer "how did my training look this week" or "show my sleep last month" from my real data. A few of the answers come back as interactive charts instead of text.

It is free right now and early, and it is just me building it, so I am mostly looking for people to tell me where it falls over. It works the same in ChatGPT if you live there instead.

I will leave the connector URL and the public tool catalog in a comment rather than the post.

I was an early GPT adopter, but it could never see my own health data. I track workouts, sleep, and a Fitbit, and getting any of that into a conversation meant screenshots or copy-paste. None of the device makers ship an MCP server, and the community ones are self-host projects I did not want to maintain.

What worked was a hosted MCP connector. I connect my devices once on the web, then in GPT you add a custom connector (paid required sadly), and from then on ChatGPT can answer "how did my training look this week" or "show my sleep last month" from my real data.

I kept wanting to ask ChatGPT (and later when I moved to Claude) about my own training, calories and sleep, but there is no official Fitbit, Oura, or Apple Health MCP server. The community repos exist, but every one I tried meant running it myself, storing OAuth secrets, and babysitting token refreshes. I just wanted to connect once and ask questions.

So I made a hosted one. You connect a device over OAuth on the web side, and it exposes everything to any MCP client through one authenticated endpoint. 60 tools across workouts, sleep, nutrition, body metrics, labs, and recovery, plus a few that render inline charts instead of a wall of numbers. It speaks streamable HTTP, so on claude.ai it is just Add custom connector and authorize. Desktop and scripted clients use a personal API key as a bearer token.

It is honestly early and it is just me building it. I would rather hear where it breaks than hear that it is neat. The full tool catalog and JSON schemas are public so you can see exactly what it exposes before you connect anything, and it is listed in the official MCP registry now.

I will put the repo and the endpoint in a comment so this is not just a link drop. Happy to get into how the OAuth and dynamic client registration flow and the inline-chart widgets are wired up.

So, I built a thing for myself that I'd like to share with others. The common pattern for AI health tools is one general chatbot answering questions with no real context. I went the other way and built eight specialist agents, training, nutrition, longevity, recovery, biohacking, running, and so on, that all read from one shared memory of the full history and synced wearable data.

The interesting design problem was that a search box that knows nothing about you can only give the average answer. Routing a question to the right specialist while keeping one shared context made the answers specific to the actual person. There is also an n of 1 experiment mode that tracks an intervention window and reports whether the metric moved.

It is early and solo. Free while I learn. Happy to talk architecture, the model routing and the shared memory design, in the comments. I will keep the link there too.

I have tracked macros for years and the two things that always wore me down were not knowing my real maintenance calories and the sheer friction of logging every day. Most apps hand you a formula number and a tedious search bar.

So I built my own. It works out your real TDEE from your actual intake and weight trend, so the number adapts to you instead of guessing. Casey, the nutrition coach I built, reads it without any good food or bad food moralizing. My goal is the easiest, most pain free calorie tracking I can manage, and I need real users to tell me where it is still annoying.

It is early and free right now. If you track macros closely I would love your honest read on the logging flow specifically. I will drop the link in a comment if that is allowed

Like a lot of you I have years of Apple Health data, rings, workouts, heart rate, sleep. Most apps either ignore it or just re-display it. I wanted something that reads it and tells me what to do next.

I built one app that holds Apple Health alongside my food and lifting in one memory, with eight specialist coaches on top, a strength one, a nutrition one, a biohacker, and so on, that all read the same history. So a question gets an answer that accounts for everything, not just the last workout.

It is early and it is a solo project. Free right now while I figure out if it helps people other than me. Would love feedback from this crowd specifically since you all already track. Link in a comment if that is okay here.

I have used a Fitbit for a long time and always felt the data went shallow once you got past steps and sleep. I wanted it to actually inform my training and recovery, not just sit in a separate app.

So I made one place that pulls Fitbit in with my workouts, food, and labs, with coaches that read all of it together. Max, the biohacker coach I built, knows your resting heart rate trend and what you actually did that week, which is a lot more useful to me than another dashboard.

It is still early and it is just me. It is free while I build it out. If you are a Fitbit person who has felt the same, I would love to hear if this scratches the itch. I can drop the link in a comment if the mods are fine with it.

I track a lot about myself, and I got tired of all of it living in separate places that never talked to each other. I wanted one spot that just holds everything and actually does something with it instead of handing me another chart.

So I built that. You can log basically anything you want to track about yourself, training, food, sleep, labs, mood, whatever you care about, and it also pulls in Apple Health, Fitbit, Oura, and Health Connect. It all sits in one unified profile, so when I ask a question the answer accounts for the whole picture and not just one slice of it.

I built it for me first, but it ended up working well enough that I want to know if it helps people who track as closely as this sub does. It is early and free right now while I figure out what is actually useful. Honestly I would rather hear where it falls short than hear that it is good. Also connects to chatgpt and claude if you prefer to chat about it / log that way.

Happy to answer anything. I will drop the link in a comment if that is allowed here.
