Fulcra connects your Apple Health data — from Apple Watch, Oura, Garmin, Whoop, CGMs, and more — to any AI agent you use. And, you can take it agent to agent, securely.

Read https://docs.fulcradynamics.com/agent-get-started.txt and help me connect my Fulcra Context data to this chat or agent environment.
Free tier available · Works with Claude, ChatGPT, OpenClaw, Hermes, and any Model Context Protocol (MCP)-compatible agent
CONNECT AGENTS
Fulcra is more than memory. Once your agent is connected, it can work with the agents your friends, family and colleagues use, in Claude, ChatGPT, Gemini or any other tool on Fulcra. Both sides opt in, each pair of agents gets its own channel, and nothing else in either account is shared.
Use Fulcra’s connect-our-agents skill (github.com/fulcradynamics/agent-skills) to connect me with [FRIEND OR COMMUNITY] on Fulcra.
THE PROBLEM
In January 2026, both ChatGPT and Claude launched Apple Health integrations.
But there are problems.
Within the app, Apple Health aggregates readings from multiple devices, normalizing or deduplicating them so that values are unified. But this does not happen when pulling that data into your MCP. Without normalization, your agent has no way to know which reading is accurate. With Fulcra, agents see all the data and have to figure out how to make sense of it.
When you integrate your health data with OpenAI or Anthropic, you send your health data to their servers. Their policies say they won't use it to train models. But "we've promised not to" isn't the same as "you own it and control it."
HOW IT WORKS
Install the Context app on your iPhone. Connect Apple Health, Oura, Garmin, Whoop, Dexcom, Google Calendar — whatever you already use. Fulcra collects and normalizes continuously.
Ask your agent to connect with Fulcra using a skill or prompt. Works with Claude, ChatGPT, OpenClaw, Hermes, Gemini in Colab, Copilot in Excel, or any agent you've built yourself.
Your agent reads from one normalized, deduplicated timeline of your health data — not a raw Apple Health export. Better data in, better answers out.
No separate signup — your account is created the first time you connect.
SETUP
Anything that writes to Apple Health comes along: Apple Watch, Oura, Garmin, Whoop, Withings, and Dexcom or Libre glucose monitors. You can turn on location and calendar in the same app.
Add https://mcp.fulcradynamics.com/mcp to any MCP client, or paste the prompt above into an agent. Exact steps for each tool are on its own page: Claude, ChatGPT, Gemini, OpenClaw and Hermes.
Over MCP, agents use tools such as get_sleep, get_workouts and get_time_series. Agents with a shell, and you, can use the CLI:
uvx fulcra-api catalog -n heart
uvx fulcra-api sleep-stages "1 week"
uvx fulcra-api apple-workouts "1 month"catalog -n heart lists the heart-related data types, so you can find the right one before you pull a time series.
Ask your agent: "Using Fulcra, compare my deep sleep on nights after a calendar event ending after 7pm with all other nights in the last 60 days. Show the dates you used and any nights with missing data."
WHAT FULCRA OFFERS
When your Apple Watch and Oura Ring both report HRV, Fulcra picks the right one. When two devices log the same run, Fulcra normalizes them. Your agents reason from clean data, not noise, or can see the raw data and compare devices.
Each user's data is encrypted with their own dedicated rotating keys. You control exactly which agents, coaches, or family members can see which data and you can revoke access at any time. Agents get just the data they need to answer your questions, not all of your data forever.
Every agent action is logged. You can see what any agent reads, when it reads it, and from what source.
Apple Watch, Oura, Garmin, Whoop, Dexcom, Libre, Withings, and anything else that writes to Apple Health — plus your calendar and location. For sources that don't write to Apple Health, point a connected agent at the data and it can bring it in.
Fulcra isn't locked to one agent. Connect Claude, ChatGPT, OpenClaw, Hermes, a notebook, or an agent you built yourself.
Not everything needs an agent. Query your data in Jupyter notebooks, Gemini in Colab, Copilot in Excel, or any analytics tool. Fulcra is a data layer, not just a chatbot backend.
Log what your devices can't capture: meals, supplements, medications, mood, stress, sleep environment, symptoms, and experiments.
Every data point — from wearables, apps, and your own annotations — organized into one scrollable, human-readable timeline. Search across years of history to spot patterns no single app can see.
Give your coach access to training load. Share sleep data with your doctor. Let a family member see what they need to. Each person sees only the slice you choose — with a full log of every access.
PRIVACY
Your health data is never used to train Fulcra's systems or anyone else's. This isn't a policy we can change — it's how the product is built.
Share your sleep data with your doctor without exposing your location. Share training load with your coach without exposing your medical history. Every access is logged. Grant access. Revoke it. Change agents. Keep the context.
Download everything in standard formats at any time. If you request deletion, it's gone. It’s your data, we believe it should be your decision.
FAQ
If you only ask health questions in Claude's iPhone app (US) or ChatGPT, their built-in connections are simpler. Fulcra is for when you want the same health data in desktop apps, coding agents or any MCP client, next to your calendar and location. See Is there an MCP server for Apple Health data?
No. The Context app syncs continuously, so your agent always reads current data.
Fulcra keeps the readings from each device so your agent can compare them, and it normalizes and deduplicates overlapping data so the agent isn't counting the same run twice.
Only agents and people you authorize. Data is encrypted at rest and in transit, never sold, and never used to train Fulcra's systems or anyone else's. You can share one slice, such as sleep with a coach, and revoke it any time. See Let someone else's agent see some of your context.
Yes. Ask your agent to create a custom data type and record entries over time, then chart them next to your health data. See How can an AI agent track a custom metric over time?
Yes, if you turn on location in the Context app. Agents can then ask where you were at a given time. See How can an AI assistant use my location history?
It depends on what you want to remember. Semantic memory servers recall facts from past chats, while Fulcra suits a user-owned store of files, records and health data shared by all your MCP clients and agents. Read the full answer.
Yes. A user-owned store like Fulcra lives outside any one assistant: you can export or delete it, and any agent you choose can read and write it. Read the full answer.
