A calorie tracker that connects to Claude and ChatGPT

You log meals in the Know My Meals app. Then you can connect it to Claude or ChatGPT and ask about your eating there: your protein this week, what drives your calories, or a table of everything you ate in October.

Where it works today

ClaudeWorks now. Add it as a custom connector with one URL
ChatGPTAdd it as a custom connector with the same URL, on ChatGPT plans that allow custom connectors. See ChatGPT setup

You need a Know My Meals account with an active plan. The connector is included in the $11.99 a month or $71.99 a year subscription.

What it can read

Claude can read your logged meals and ingredients, calorie and macro totals, and targets. It can also access the profile details you entered, including goal, height, weight, age, sex, activity level, dietary style and restrictions.

Use it to understand eating patterns and see which foods contribute the most calories or protein.

Totals and averages count only meals you've confirmed with Log meal, so unchecked estimates don't skew the numbers.

What it can't do

  • It can't log meals. The connector is read-only. It can't add, change or delete anything. You log in the app.
  • It can't see your coach chats, your voice recordings or your payment details.

Details are in the privacy policy, section Connected AI assistants.

Things to ask

  • "How was my protein this week compared with last week?"
  • "Do I eat more on weekends?"
  • "Where do most of my calories come from?"
  • "I've got 600 calories left. Ideas for dinner?"
  • "Make a chart of my daily calories for October."

Set it up in Claude

  1. In Claude, open Settings, then Customize.
  2. Open Connectors, tap Add, then Add custom connector.
  3. Name it Know My Meals and paste this URL: https://api.knowmymeals.com/mcp
  4. Tap Add, then Connect, and sign in with your Know My Meals account.

You can disconnect any time in Claude. The full help page is Connect your AI.

Other apps with assistant connections

If logging from inside the chat is what you want, Know My Meals doesn't do that today. Some apps do:

  • Foodnoms says its connector lets Claude and ChatGPT both read your log and log food, and it needs a Foodnoms+ subscription1.
  • MyFitnessPal has an app inside ChatGPT for recipe ideas and macro and protein guidance2.

Ask Claude which foods contribute the most calories or protein, using the ingredients and amounts in your meal log.

Questions

Can I log food from ChatGPT or Claude with Know My Meals?

No. The connector is read-only. You log meals in the Know My Meals app by talking, typing or taking a photo, and Claude can then read them and answer questions.

Does Know My Meals work with ChatGPT?

Yes. Add Know My Meals in ChatGPT as a custom connector with the URL https://api.knowmymeals.com/mcp and sign in with your Know My Meals account. ChatGPT allows custom connectors only on some plans and workspaces, so check your account first.

Is my data safe if I connect it?

You choose when to connect, you sign in with your Know My Meals account, and you can disconnect any time in Claude. The connector can't see coach chats, voice recordings or payment details, and it can't change anything.

Do I need to pay for Claude?

Custom connectors are a Claude feature, so check which Claude plans include them. On our side you need an active Know My Meals plan.
