MacroFactor MCP

Your MacroFactor nutrition in ChatGPT and Claude, through Apple Health or Health Connect.

MacroFactor has no official MCP server.

Memory.fit is a hosted MCP server for athletes. It has no direct MacroFactor connection: link MacroFactor to Apple Health or Health Connect, connect Apple Health or Health Connect in the Memory.fit app, add one address to your AI, and it reads the day's calories, protein, carbs and fat, fiber, sugar and sodium, when shared.

You need the Memory.fit app on Android (the iPhone app is coming), and an AI that can add a custom connector.

Your options

Every way to get MacroFactor into an AI

MacroFactor runs no MCP server. Community servers run on your own computer, hosted services run it for you, and so does Memory.fit.

OptionWhat you need
Hosted MCP serverMemory.fit MCPHosted, in ChatGPT, Claude, Grok Bot, Gemini and any MCP appThe Memory.fit app with Apple Health (iPhone) or Health Connect (Android) connected, and MacroFactor exporting nutrition there. $9 a month or $69 a year, with 7 days free.

When another option is better

  • You want your AI to log food straight into MacroFactor: there is no working way today, since MacroFactor has no public API. Memory.fit reads your daily totals and changes nothing in MacroFactor.

Limits, said plainly

  • MacroFactor has no public API. What your AI sees is what MacroFactor exports to Apple Health or Health Connect.
  • MacroFactor shares a daily total, not single meals. It counts on days nothing else was logged.
  • Memory.fit reads your nutrition and changes nothing in MacroFactor.

Questions

MacroFactor MCP, in short.

  • No. MacroFactor does not run an MCP server.

  • Yes, through Apple Health or Health Connect. Link MacroFactor to Apple Health or Health Connect, connect Apple Health or Health Connect in the Memory.fit app, add Memory.fit to ChatGPT as a connector, and ChatGPT reads each finished session. Claude and every MCP app work the same way.

  • No. Memory.fit is hosted: you add one address to your AI and sign in with your Memory.fit account. Nothing to install, no password of another service to paste.

  • Each AI gets only the permissions you allow, every change shows in the app with who made it, and you can disconnect an AI or a source at any time.

  • MacroFactor exports daily totals of calories, macros and micronutrients to Apple Health and Health Connect, so meals stay in MacroFactor. If your AI logs a meal, the day counts it once alongside the total.
