MCP server
Early access · what's next

Your AI, meet your Apple Health.

MetricBridge lets Claude, ChatGPT and Cursor read your Apple Health data through a free, open-source MCP server, with no account and no MetricBridge server in the path. It's available today.

Coming next, still in testing: more sources alongside Apple Health (Oura, Whoop, Garmin), agent skills, and a pilot for coaches. Join the list and we'll email you once when early access opens.

We'll send a confirmation link first. We store only your email, the option you pick below, and which link brought you here. Details in our privacy policy.

We've sent a confirmation link to . Tap it and you're on the list. It can take a minute; check spam if it doesn't arrive.

Optional: what would you use this for? It helps us invite you to the right pilot.

Real answers, with the numbers behind them

Ask an agent a plain-language question. It calls the read-only MCP server, the real numbers come back, and every answer carries its provenance: the metric, the window, the date range. This works today. (Example below, with made-up numbers.)

claude · health-export-mcp · your-machine
you: why is my recovery slipping this week?
→ get_trends(metric: "heart_rate_variability")
HRV 7d avg 54 ms vs 62 ms prior (−13%)
→ get_sleep_sessions(start: "Mon", end: "Sun")
asleep after 00:30 on Weds + Thurs, 6h 05m avg
→ get_workouts(start: "Mon", end: "Sun")
evening runs Weds + Thurs, ended 22:10 and 22:40
samples: 7 · window: Mon to Sun · read-only, on device

How it works

1
Export from the app (on-device).
The MetricBridge app writes your Apple Health data as local JSON to a place you choose.
2
Add the MCP server (one command).
claude mcp add health-export -e HEALTH_DATA_DIR="/path/to/export" -- npx -y health-export-mcp
3
Ask your agent.
Sleep, heart rate variability, workouts, trends over time. With the numbers and the provenance.

The wedge, stated plainly

  • No MetricBridge server. The app writes your data where you choose, and the MCP server reads it on your own machine. Nothing passes through us.
  • No account. There is no MetricBridge account. Your data goes only where you send it.
  • Provenance on every answer. Every number names its metric, window and date range.
  • Works with Claude, ChatGPT, Cursor, and any MCP client (Claude Code, VS Code, opencode, OpenClaw, Hermes).

For coaches and teams

Fitness, running and wellness coaches: help clients bring their own Apple Health numbers to your sessions. It's the same read-only server, pointed at an export the client shares with you, using a pairing code the client controls and can revoke.

MetricBridge is a wellness tool, not a medical device. It doesn't diagnose, treat or monitor any condition, so please don't use it for clinical decisions.

Coaching on your own? Join the list above and pick "Coaching clients" after you sign up, and we'll invite you to the coaching pilot first.

Running a team, club or organisation? Talk to us directly: Email us about a team pilot

It goes to the founder, who replies personally. Tell us your sport, roughly how many people, and what you'd want to see. Please don't send anyone's health data.

Questions

Does my health data leave my phone?

Only to the destination you configure (iCloud Drive, a local folder, your LAN, or a webhook you run). There is no MetricBridge server in the loop, and the MCP server makes zero network requests. One thing to know: when your agent calls a tool, the numbers it asked for go to that agent, like anything else you share with it. With Claude or ChatGPT that means their service, under their terms. With a local model it stays on your machine.

What does joining the list get me?

One email when early access opens, and nothing else. Access isn't guaranteed: these features are still being tested, and pilots may be small. You can unsubscribe at any time from the link in the email.

Is MetricBridge out already?

Yes. The app, the Apple Health export and the MCP server are available today. The list is only for what comes next.

What does it cost?

The app is a single $24.99 one-time unlock with no account. The upcoming agent skills are included in that unlock at no extra charge.

Which clients are supported?

Claude Desktop, Claude Code, ChatGPT (via MCP), Cursor, VS Code, opencode, OpenClaw, Hermes, and any other MCP client. The server is zero-dependency and runs wherever Node.js runs.

Do I need the app to use the MCP server?

Yes. The server reads the JSON export the MetricBridge app writes. The server itself is free and open source; the app that produces the export is the one-time purchase.
