Ask your body
anything.
freddy is an MCP server that plugs your wearables, CGMs, power meters, and gym apps straight into Claude, ChatGPT, and any AI agent that speaks MCP. Stop staring at dashboards. Just have the conversation.
ChatGPT
Your devices know everything.
Their apps tell you nothing.
You're collecting more signal than any athlete in history: sleep, HRV, glucose, power, lifts. The apps that ship with it ask you what you want for breakfast.
Three apps. Twelve scores. Zero answers.
You open Oura. Then WHOOP. Then Garmin. Then Dexcom. Then Hevy. Each one tells you a number. None of them tell you why.
One MCP. One conversation.
Connect freddy once. Then ask Claude, ChatGPT, or your favorite agent the question you actually have. They'll pull from your real numbers instead of guessing.
Built for the way
you track.
Three kinds of people get the most out of freddy. Find yourself, then steal their questions.
Athletes
Training load, recovery, race readiness. Ask hard questions across every session you have ever logged.
Biohackers
Cross-source experiments: sleep against glucose against bedroom air. Test what actually moves your numbers.
Longevity & healthspan
The long game: resting heart rate, HRV, weight and sleep drift measured over years, not weeks.
Three minutes.
Then ask anything.
No app to install. No new login to remember. freddy lives inside the AI tools you already use.
Connect your sources.
OAuth into Oura, WHOOP, Polar, Garmin, Dexcom, Wahoo, Hevy, and more. Read-only, revocable, encrypted.
Add it to your AI.
Find freddy in ChatGPT's app directory, or paste your MCP URL into Claude and any agent that speaks MCP.
Ask your AI anything.
Your data lives where the conversation happens. Real answers from your model, grounded in the numbers freddy serves.
Wherever you talk to AI,
freddy is there.
Chat with it, automate it, or build on it. Same data, same URL, your choice of surface.
In chat
Ask in plain language and get answers grounded in your own numbers. One click and you are in.
