SomviaWhat an Apple Health MCP server does
Apple Health stores data on your iPhone. An MCP server gives a compatible AI client a standard set of tools for reading that data. Instead of pasting a screenshot or uploading one giant file, the client can ask for a bounded date range, list the available workout sessions, and fetch a deeper series only when the question needs it.
Somvia separates the two jobs: the iPhone app handles Health authorization and syncing; the hosted MCP endpoint answers authenticated, read-only tool calls. The endpoint is https://somvia.app/mcp.
The useful distinction is depth, not “AI health” in general. Daily totals can answer “how many steps?” Training questions often need the session underneath them: intervals, splits, heart-rate shape, speed, power, or cadence.
How the remote MCP flow works
-
Choose what Somvia may read
Install Somvia on iPhone, sign in with Apple, and authorize only the Apple Health categories you want to share.
-
Sync the history you need
Choose how far back the first sync reads daily measurements: 7, 30, 90, or 180 days. Workout sessions and available detail series go back 180 days. New data keeps syncing after that and stays on the server until you delete it.
-
Connect your MCP client
GUI clients can use OAuth and Sign in with Apple. Headless or autonomous agents can use the private
som_access token shown in the app. -
Ask from the agent you already use
The agent discovers Somvia's tools and fetches only the structured data required for the answer. It answers with the model you selected in it, so you can use the strongest model you have, and that model only changes when you change it. Somvia runs no model of its own.
Remote MCP, local MCP, or export?
| Approach | Good fit | Trade-off |
|---|---|---|
| XML or CSV export | One-off archival analysis and tools that ingest a complete file | Manual, often large, and quickly becomes stale |
| Local MCP server | Users who want processing tied to their own computer | A machine and local server must remain available to the client |
| Somvia remote MCP | Automatic sync and access from multiple agents or devices | Selected data is stored on Somvia's managed cloud service until you delete it |
No option is universally best. Somvia is designed for people who value a continuously available endpoint and structured workout depth more than an entirely device-local workflow.
Apple Health MCP servers compared
Each row below comes from the product's own website, documentation or GitHub README, checked on October 19, 2026. Prices are US list prices.
| Product | How data arrives | Server and sign-in | Workout detail and scores | Price |
|---|---|---|---|---|
| Somvia | iPhone app syncs the Health categories you select to your Somvia account | Hosted, Streamable HTTP. Sign in with Apple over OAuth, or an app-issued token for agents without a browser | Splits, and heart-rate, speed, route, power and cadence series when Apple Health recorded them. Recovery score, training load, threshold pace and race predictions | Pro from $4.99 a month, with annual and lifetime options |
| HealthAPI | iPhone app uploads your history, then syncs in the background | Hosted, Streamable HTTP. OAuth approved on the iPhone, or an API key | Raw samples at full resolution, such as heart rate during a run, up to 31 days per request. No computed scores listed | Pro $4.99 a month (100 requests a day), Developer $9.99 a month |
| AthleteData | iOS app in TestFlight beta. Apple Health is one of more than 30 sources | Hosted. OAuth, or a keyed URL | Laps, per-kilometer splits on some runs, heart rate, cadence and pace every 10 to 25 seconds, no route. CTL, ATL, TSB and training load | MCP plan $9 a month or $69 a year, coaching $39 a month |
| Attune | iPhone app syncs Apple Health daily | Hosted, Streamable HTTP. Bearer token, and Claude Desktop connects through mcp-remote | HRV, sleep, heart rate, workouts and weight, with a readiness score | Pro $1.99 a month |
| Wellness Project | iPhone app reads Apple Health | Hosted, listed in Claude's connector directory. OAuth | Workouts, sleep stages, resting heart rate, HRV, body metrics and labs, as daily rows with baselines and trends | Pro $9.99 a month |
| HealthKite | Reads HealthKit live from the iPhone at query time, with no cloud copy | Local stdio server on your computer. The iPhone app must stay in the foreground on the same Wi-Fi. Pairing secret | Individual samples, including a workout's heart-rate series. No computed scores listed | Free |
| MetricBridge (health-export-mcp) | iPhone app exports 190 metrics to iCloud Drive, a synced folder or your local network | Local stdio server. Optional pairing code | One summary per workout, with no individual samples and no routes. Trends and period comparisons | MCP server free, app $24.99 one-time |
| vpetersson/apple-health-mcp-server | Manual Apple Health export, imported into DuckDB | Local, Streamable HTTP or stdio | Workout statistics, GPS routes, ECG waveforms and custom SQL. No computed scores | Free, MIT license |
| Open Wearables (Momentum) | Self-hosted platform. Apple Health through its iOS SDK or an XML upload | Your own backend, with a local MCP server | Daily summaries, workouts and intraday heart rate | Free, MIT license, self-hosted |
How to choose
- Nothing may leave your devices: HealthKite reads the iPhone live over your local network. vpetersson's server and MetricBridge keep the data in files you control.
- Claude on the web, ChatGPT, or an agent on a server: these clients reach a hosted server over the internet without a computer left running. Somvia, HealthAPI, AthleteData, Attune and Wellness Project are hosted.
- The agent should read training scores: Somvia calculates recovery, training load, threshold pace and race predictions on the iPhone. AthleteData calculates CTL, ATL and TSB.
- You only use the ChatGPT or Claude app in the US: both now read Apple Health directly. See the ChatGPT and Claude guides for when that is enough.
What an agent can query
| Layer | Examples | Why it matters |
|---|---|---|
| Daily measurements | Sleep, HRV, resting heart rate, steps, active energy | Trend and cross-metric questions |
| Workout summary | Activity, duration, distance, pace, energy, splits | Compare sessions without loading every sample |
| Workout series | Heart rate, speed, route, power, cadence, stroke rate | Analyze intervals, effort shape, pacing, and recovery |
The exact fields depend on what Apple Health recorded and what you selected. Somvia never invents a missing series, and it does not write to Apple Health.

Questions worth asking
- Compare my last four interval runs. Did pace improve at a similar heart rate?
- How did sleep duration and HRV change on the nights before my strongest workouts?
- Show the pacing and heart-rate drift across my long runs this month.
- Which training days were followed by a lower resting heart rate instead of a higher one?
These are personal fitness and wellness questions, not medical diagnosis. Use qualified medical care for symptoms, treatment, or clinical decisions.
Frequently asked questions
What is an Apple Health MCP server?
It is a bridge that exposes authorized Apple Health measurements as structured, read-only tools using the Model Context Protocol. A compatible AI client can request only the dates and detail needed for a question.
Does Somvia require an Apple Health XML export?
No. The Somvia iPhone app reads the Health categories you authorize and syncs the selected history to a private remote MCP endpoint.
Which Apple Health MCP server should I use?
If nothing may leave your own devices, use a local server such as HealthKite or a server that reads an Apple Health export. If you want Claude on the web, ChatGPT, or an agent on another machine to reach your data without a computer left running, use a hosted server such as Somvia, HealthAPI or AthleteData. Somvia also gives the agent a recovery score, training load, threshold pace and race predictions calculated from your history.
Which AI clients can connect?
Somvia uses standard Streamable HTTP MCP. OAuth-capable clients can sign in with Apple, while clients that connect with a key, such as Hermes, OpenClaw, Grok and Muse, can use an app-issued bearer token.
