Using Mealuna with an AI assistant

What it is

Once Mealuna is connected to an assistant that speaks MCP — Claude, for example — you can ask about your kitchen in plain language, and the answer comes from your own account rather than a guess.

The connection needs Mealuna Premium on the household being asked about. Ask about a household on the free plan and the assistant is told so by name.

A new connection only reads unless you tick Allow changes when you connect. The three guides below show what you can ask, and what the assistant does once you allow changes.

Your pantry and shopping lists

Ask what is in the pantry, what is about to expire, what is on a list and what you may need soon. With changes allowed, it adds to a list, ticks the cart, removes items and says what ran out. It also adds what you bought from a receipt and takes stock of the fridge from a photo.

Recipes and the menu

Ask what to cook — by time, diet, what is about to expire or what your group likes. With changes allowed, it plans meals as drafts, saves, changes and deletes your group's recipes, and sets your favourites.

Logging what you ate

Tell it what you ate and it hands you a link that opens Mealuna with the meal filled in. Nothing is saved until you press Log. If it was one of your Mealuna recipes, the link opens that recipe on its Mark as eaten card instead.

Allowing changes

A connection only reads unless you allow changes. To let an assistant make changes, tick Allow changes on the Mealuna page that opens when you connect — or later open the Mealuna app, go to Settings → AI assistants and turn on Allow changes for it. Turning it off there takes the permission away again, with no need to connect again. If you connect the same assistant again, what you choose on that page replaces the earlier choice.

It changes something only when you ask. If what it was about to change changed after it looked, it leaves it alone and says so. For a receipt or a photo, it first shows what it will add and change, and writes only after your yes.

When a recipe or a food list names something Mealuna does not know, it becomes a product of your group, the same as typing it in the app. It has no nutrition until you add it in the app. From a receipt or a photo, a new product is made only when you agree.

What it cannot do

Apart from menu drafts, your favourite marks, your group's own recipes, your shopping lists and your pantry, nothing in your account can be added, changed or deleted — not your groups, and not which lists you have. It cannot publish a recipe or confirm a meal in your menu.

Your food diary never leaves your phone, so it cannot be read at all — the logging link exists precisely because there is no other way in.

Connecting, and disconnecting

In Claude, Mealuna is in the connector directory: Customize → Connectors, choose + and search for Mealuna. In ChatGPT, Mealuna is in the plugin directory: open Plugins, search for Mealuna and choose Install plugin. In any other assistant, setup is on the AI connection page at mealuna.eu/mcp: add one address as a custom connector. Either way you then continue with Apple or Google on the Mealuna page that opens — that is the approval. There are no keys to copy.

Your assistant keeps its own copy of what Mealuna can do, so a new ability may not reach it straight away. If Claude says it cannot do something these guides describe, refresh the connector's tool list: Settings → Connectors → Mealuna → ⋮ → Refresh tools list. Only if that does not help, remove the Mealuna connector and add it again. In ChatGPT there is nothing to refresh: OpenAI checks Mealuna's new abilities and adds them to the plugin itself, so they can take a while to appear there.

In the Mealuna app, Settings → AI assistants lists every assistant you connected, where each connection goes, and when it was connected and last used. Allow changes and Disconnect are there.

Removing the connector in your assistant stops that assistant using it, but does not end the connection on Mealuna's side: disconnect it in the app, or it ends by itself 30 days after it was last used. Deleting your Mealuna account removes every connection with it.
