You can now ask an AI assistant about your own training and get an answer built from your real numbers instead of a guess. The plumbing behind it is MCP, the Model Context Protocol, and fitness apps are adopting it unevenly: Strava has a connector for Claude but not ChatGPT, Hevy has one for ChatGPT but not Claude, and Garmin, Whoop and Oura have none of their own. We went through every fitness app we could find with an MCP connector in November 2026: which assistants each one works in, what it can read, whether it can change anything, and what it costs.
Disclosure: Fitcoin is our app and it is on this list. We shipped its MCP connector in November 2026, so read that section knowing who wrote it; we have tried to describe it the way we describe everyone else's, weaknesses included. We have no relationship with Strava, Intervals.icu, Hevy, Peloton, Garmin, Whoop, Oura, Google, Anthropic, OpenAI or any of the hosted services named here, and we take no referral fees.
The short version
Only a handful of fitness apps run an MCP connector of their own. Strava's works in Claude, and in Gemini for US subscribers, but not ChatGPT, and only if you pay for Strava. Intervals.icu's works in Claude, ChatGPT, Gemini and Grok on its $4 a month Supporter plan. Hevy and Peloton work inside ChatGPT only. Fitcoin's works in Claude, ChatGPT, Cursor and any other MCP client, costs nothing, and reads whatever your watch or ring writes to Apple Health or Health Connect, plus Whoop and Oura. Garmin, Whoop, Oura and Fitbit have no connector of their own, so for those you need a community server or a paid hosted service.
What an MCP connector actually does
MCP, the Model Context Protocol, is an open standard Anthropic published in late 2024 that lets an AI assistant call tools on another service. For fitness it works like this: you ask "how did I sleep this week compared with last week?", the assistant asks the fitness app for your last fourteen nights, the app sends back the numbers, and the assistant answers from them instead of guessing. You add the connector once, sign in to the fitness app in a pop-up, and tap Allow. After that it only reads when you ask a question.
Three kinds of connection get called "MCP" in search results, and the difference matters for your privacy:
- First-party connectors are run by the fitness app itself. Your data goes straight from the app you already trust to the assistant. Strava, Intervals.icu, Hevy, Peloton and Fitcoin are in this group.
- Hosted third-party services sign in to your wearable account for you, keep a copy of your data and serve it to the assistant. They fill the gap for brands with no connector, at a monthly price, and add another company that holds your health data.
- Community servers are open-source projects you run on your own computer with your own API keys. Free and private if you set them up well, but they are hobby projects and most only work with desktop apps such as Claude Desktop or Cursor.
Separately, Claude and ChatGPT both have built-in health features that read Apple Health directly. Those are not something you add by URL, and both are still US-only. We cover them below.
Every fitness MCP connector, compared
| App | Who runs it | Claude | ChatGPT | Cursor and others | Cost |
|---|---|---|---|---|---|
| Fitcoin | Fitcoin | Yes | Yes | Any MCP client | Free |
| Strava | Strava | Yes | No | Gemini (US) | Strava subscription |
| Intervals.icu | Intervals.icu | Yes | Yes | Gemini, Grok | $4 a month |
| Hevy | Hevy | No | Yes, @hevy | No | Free |
| Peloton | Peloton | No | Yes | No | Peloton account |
| Garmin | Community or hosted | Via others | Via others | Community servers | Free to about $9 a month |
| Whoop | Community or hosted | Via others | Via others | Community servers | Free to about $10 a month |
| Oura | Community or hosted | Via others | Via others | Community servers | Free to about $10 a month |
"Via others" means the brand has no connector, but a hosted service or community project can bridge it. Prices for those are covered further down.
The connectors, one by one
1. Fitcoin: free, read-only, and works in every assistant
Fitcoin is a fitness rewards and insights app. It reads Apple Health on iPhone and Health Connect on Android, with optional direct Whoop and Oura connections, and turns that into a daily FitScore, SleepScore, Recovery and Energy. Its connector, at https://www.fitcoin.co/api/mcp, gives an assistant eleven read-only tools: today's scores, history for any metric, workouts, sleep, food diary, gym sessions with sets, check-ins, cycle logs if you keep them, your profile basics, and your in-app balance, streak and challenges.
Because Fitcoin sits on top of Apple Health and Health Connect, it is the indirect route to data from brands with no connector of their own. A Garmin, Galaxy Watch, Pixel Watch or smart ring that writes to Apple Health or Health Connect ends up readable by your assistant through Fitcoin. Unlike the built-in health features in Claude and ChatGPT, it also works outside the US.
- Works in: Claude (web, desktop and mobile), ChatGPT, Cursor and any client that supports remote MCP. Clients that cannot open a sign-in window can use a personal key instead.
- Can it change anything? No. It cannot log workouts, edit your profile, post or spend anything.
- What it cannot see: other members, messages, precise GPS routes, reward codes, payment details, your email address or phone number.
- Off by default: nothing is shared until you sign in and tap Allow, and you can revoke one assistant or switch the whole thing off at fitcoin.co/connect.
- Limits: up to 240 reads a day per connection; personal keys last a year.
The honest weaknesses: it is new, so it has less history behind it than Strava's. It only knows what reaches Fitcoin, so a device that never writes to Apple Health or Health Connect is invisible to it. And it is read-only by design, so it will not put a workout on your calendar the way Intervals.icu can.
2. Strava: official, but Claude and Gemini only
Strava launched its own connector on 1 June 2026. It started on Claude, added Google Gemini for US subscribers from late October 2026, and still has no ChatGPT version. It is read-only: it can read your activities and training history but cannot upload or edit anything. It is included with a paid Strava subscription, including the Strava and Runna bundle, Family and Student plans; a free trial does not qualify. You revoke it from the MCP section of Strava's settings.
In Claude you find it in the connector directory rather than pasting a URL. In Claude Code the command is claude mcp add --transport http strava-mcp https://mcp.strava.com/mcp.
One catch matters if you shop around: Strava's API terms do not let third-party apps pass Strava data to AI tools. That is why the hosted multi-wearable services below leave Strava out, and why the many community Strava servers on GitHub carry a policy risk. If your activities live in Strava and you use Claude, the official connector is the one to use. Our does Strava pay you? piece covers what the subscription does and does not include.
3. Intervals.icu: the most assistants, and it can plan
Intervals.icu, the training-analysis site many cyclists and triathletes use, runs an official connector that works in Claude, ChatGPT, Gemini and Grok. It needs the Supporter plan at $4 a month. Beyond reading activities, wellness and fitness and fatigue trends, it can read your workout library and put saved workouts on your calendar. It can delete things too, and it shows you what it is about to delete and waits for a yes, even when the assistant is set to run tools without asking.
It is the most capable connector here for structured endurance training. It is also the most specialised: if you do not already use Intervals.icu, starting just for the connector means moving your training analysis there first.
4. Hevy: ChatGPT only, for building routines
Hevy replaced its old HevyGPT with an official ChatGPT plugin in September 2026. You type @hevy in any chat, describe what you want, and ChatGPT builds a routine you can send straight to the Hevy app. It works on free Hevy and free ChatGPT accounts. There is no Claude or Gemini version, and Hevy pitches it for planning rather than analysing your lifting history. Our Hevy review covers the app itself.
5. Peloton: ChatGPT only, for classes
Peloton's ChatGPT integration lets you connect your account and ask ChatGPT to find classes and build a plan around them. It was also one of the launch partners for ChatGPT Health in January 2026. It is useful if Peloton is your main workout source and you use ChatGPT, and irrelevant otherwise.
Built into the assistants: Claude and ChatGPT health features
Both big assistants now read health data directly, without a connector URL. They are worth knowing about, but check the small print before you plan around them.
| ChatGPT Health | Claude health integrations | |
|---|---|---|
| Launched | 7 January 2026 | 20 January 2026, in beta |
| Fitness sources | Apple Health (iPhone), MyFitnessPal, Peloton, Weight Watchers, AllTrails | Apple Health (iPhone), Health Connect (Android) |
| Medical records | Yes, through b.well, US only | Yes, through HealthEx and Function Health |
| Where | US; the UK, EU and Switzerland were excluded at launch | US only, on Pro and Max, when we checked |
| Works in Cursor or other clients | No | No |
If you are in the US on a paid plan and only use one assistant, the built-in route is the simplest. Everywhere else, or if you want the same data in more than one assistant, you need a connector. That is the gap Fitcoin's fills: it reads the same Apple Health data and Health Connect data, in any country, in any MCP client.
Garmin, Whoop, Oura and Fitbit: no official connector yet
None of the four big wearable brands runs an MCP server. Each has a developer API, and the community has built servers on top of them.
- Garmin opened an official Personal API to individual athletes in October 2026. It is read-only, keys expire, and it does not include the Training API, so nothing built on it can push a workout to your watch. Several open-source MCP servers use it and run on your computer. Avoid older Garmin servers that ask for your Garmin password: the Personal API makes that unnecessary. A hosted option, Fitness AI Connector, uses Garmin's Health API with a proper sign-in and is listed in ChatGPT's directory.
- Whoop has no official server. Community and hosted ones use the Whoop Developer API to read recovery, strain, sleep and workouts. If you are weighing up the strap itself, our Whoop alternatives guide may help.
- Oura has no official server either. Oura retired personal access tokens in December 2025, so working servers now sign in with OAuth; older guides that tell you to paste a token are out of date.
- Fitbit and Pixel Watch are mid-migration: Google is replacing the Fitbit Web API with the Google Health API in late 2026, so check that any server you pick has moved over.
The simplest workaround for all four is to let the device write to Apple Health or Health Connect, which they all can, and connect something that reads from there. Our guide to wearing an Oura Ring with an Apple Watch explains how those sources merge.
Hosted services that bundle several wearables
If you want one connector for several brands and are happy for another company to hold a copy of your data, these are the main paid options. Prices are as each service listed them in November 2026.
| Service | Covers | Price as listed | Worth knowing |
|---|---|---|---|
| athletedata | Garmin, Whoop, Oura, Hevy and more | $9 a month for the MCP tier | Leaves out Strava because of Strava's API terms |
| freddy | Several wearables | Free for one source and 7 days; $49 a year for the rest | Listed in Claude's connector directory |
| Wellness Project | Fitbit, Health Connect, Apple Health, Whoop | Free Basic; Pro $9.99 a month | Connector included on the free tier |
| IcuSync | Intervals.icu | $20 a year | Works on the free Claude plan |
Before you connect health data to any assistant
Five questions we would ask of any connector, ours included:
Which one should you use?
- Apple Watch, Android phone, any assistant, any country: Fitcoin. Free, and it covers everything that reaches Apple Health or Health Connect.
- Strava subscriber who uses Claude: Strava's own connector.
- Structured cycling or triathlon training: Intervals.icu, for the planning tools.
- Lifter who wants ChatGPT to write the routine: Hevy.
- US iPhone user on a paid ChatGPT or Claude plan: the built-in Apple Health feature, if one assistant is enough.
- Garmin owner who likes to tinker: a community server on Garmin's Personal API.
They are not exclusive. Claude and ChatGPT both let you add several connectors, and an assistant will happily pull your runs from Strava and your sleep from Fitcoin in the same answer. If you are still choosing where your runs should live in the first place, see our best running apps roundup.

Frequently asked questions
Which fitness apps work with Claude?
Fitcoin, Strava and Intervals.icu all run official connectors that work in Claude. Strava's needs a paid Strava subscription and Intervals.icu's needs its $4 a month Supporter plan; Fitcoin's is free. Garmin, Whoop and Oura data can reach Claude through community or hosted servers, or through Fitcoin if the device writes to Apple Health or Health Connect.
Which fitness apps work with ChatGPT?
Fitcoin, Intervals.icu, Hevy and Peloton have official ChatGPT connections. ChatGPT Health also reads Apple Health, MyFitnessPal, Peloton, Weight Watchers and AllTrails directly in the US. Strava has no official ChatGPT connector.
Does Strava work with ChatGPT?
Not officially. Strava's own connector works in Claude, and in Gemini for US subscribers. Strava's API terms do not allow third-party apps to pass Strava data to AI tools, so unofficial ChatGPT workarounds carry a policy risk.
Does Garmin have an MCP server?
No. Garmin opened an official read-only Personal API to individual athletes in October 2026, and several community MCP servers are built on it, but Garmin does not run an MCP server itself. Garmin data that syncs to Apple Health or Health Connect can also reach an assistant through Fitcoin.
Can I connect Apple Health to Claude or ChatGPT outside the US?
Not with their built-in health features, which were US-only when we checked in November 2026. A connector such as Fitcoin's reads Apple Health on your iPhone and works in Claude and ChatGPT in any country.
Can Cursor read my fitness data?
Yes, through any connector that supports remote MCP. Fitcoin's works in Cursor with a sign-in, or with a personal key added to Cursor's MCP settings. Most community Garmin, Whoop and Oura servers are built for desktop clients like Cursor too.
Is it safe to connect fitness data to an AI assistant?
It can be. Prefer a connector run by the fitness app itself, that is read-only, that asks you to approve access on its own page rather than taking your password, and that lets you revoke access. Remember that what the assistant reads becomes part of your chat with it.
What is a fitness MCP server?
A service that lets an AI assistant ask a fitness app for your data using the Model Context Protocol. You add its URL to Claude, ChatGPT or Cursor, sign in to the fitness app and allow access, and the assistant can then answer questions from your real workouts, sleep and scores.
Method: Checked November 11, 2026 against manufacturer product pages, published help documentation and independent reviews. Prices are US list at publication unless noted. Fitcoin has no commercial relationship with the hardware brands named here. Wellness estimates only, not medical advice.
