Setup

How to connect?

Nutrio plugs into the assistant you already use. Point it at one address, sign in once, and approve what it's allowed to do — then log a meal just by saying what you ate.

Claude

One tap

Claude takes a prefilled install link — the name and address are already filled in, so you just confirm and sign in.

Tap the button below; Claude opens on the add-connector dialog.
Confirm the connector. Nothing is shared yet.
Sign in to Nutrio and approve what Claude can do.

Claude asks for your approval the first time it uses a tool, so nothing lands in your journal unseen.

ChatGPT

On a computer

ChatGPT has no install link, so you paste the Nutrio address in yourself. Custom connectors are set up on a computer rather than on your phone.

Open Settings → Apps → Advanced settings and turn on Developer mode. OpenAI renames and moves this pane between releases — if it isn't there, search your settings for “developer”.
Create a connector, paste the Nutrio address, and name it Nutrio.
Sign in to Nutrio when it asks, and approve access.
In a new chat, open + → Developer mode and tick Nutrio.

ChatGPT asks you to confirm before it writes anything, so nothing lands in your journal unseen.

Or any other MCP-compatible client

Nutrio is a standard remote MCP server, so it isn't tied to either of those two. Cursor, Zed, your own agent — if it can add a remote MCP server, it can add Nutrio.

and anything else that speaks MCP

The Nutrio address

This is the only thing you ever paste. There is no password and no API key — your client identifies itself, sends you here to sign in, and you approve access on a screen that names it.

Transport: Streamable HTTP
Authentication: OAuth 2.1 with PKCE, client ID metadata documents or dynamic registration
Discovery: /.well-known/oauth-protected-resource/mcp

Then just talk

Say what you ate in ordinary words and it lands in today's journal, using the foods you've already saved.

“Chicken gyros and an ayran for lunch”“How's my week looking?”“What fits in the calories I have left?”

You can disconnect at any time from Settings in the Nutrio iOS app — it stops all access immediately and leaves your journal untouched. Stuck? Write to hello@nutrioapp.com and a real person will reply.
