Connect Fuuud to Claude, ChatGPT and Cursor

Your Fuuud memory can follow you into the AI apps you already use. Add one connector and any app that supports MCP can check meals against your allergies.

Last reviewed 7 October 2026

The connector URL

One address works for every app:

https://www.fuuud.site/api/mcp

It is a hosted MCP server protected by OAuth, so you sign in once and each app gets its own key. Apps do not need your password and never see the health record unless you approve it.

Add it to your app

Menu names change between versions, so look for “connectors” or “MCP” in settings.

Claude (web, desktop and mobile)

In settings, open Connectors and add a custom connector, then paste the URL. Custom connectors are on paid plans. Add it on the web; it then shows up in the mobile app.

ChatGPT

In settings, enable developer mode under advanced connector settings, create a connector, and paste the URL.

Cursor

Add it to your MCP configuration:

{
  "mcpServers": {
    "fuuud": { "url": "https://www.fuuud.site/api/mcp" }
  }
}

VS Code

Add it to .vscode/mcp.json:

{
  "servers": {
    "fuuud": { "type": "http", "url": "https://www.fuuud.site/api/mcp" }
  }
}

Claude Code and Gemini CLI

claude mcp add --transport http fuuud https://www.fuuud.site/api/mcp

For Gemini CLI, add the same URL as an HTTP server in its settings.

Approve it once

The first time, the app opens a Fuuud page. Sign in with Google, then choose whether the app may only read your memory or may also write to it. Writing is what lets it remember a new allergy. Approve, and you are sent back to the app.

What the app can do

  • recall_memory: Look up what you have told it, newest facts first.
  • remember_fact: Save a dated fact such as an allergy or a dislike.
  • forget_fact: Retract a fact. It asks you to confirm first.
  • check_meal: Check a meal against your allergies and conditions. If it cannot tell, it says unknown, not safe.
  • list_memory: Show everything it has stored, including writes still saving.

Your data in a third-party chat

Anything the app recalls becomes part of that conversation with its AI provider, under that provider's terms. Only connect apps you trust with your health information.

Disconnect it

In Fuuud, open Settings and find connected apps. Disconnecting stops the app immediately and discards the key we held for it. You can also remove its key from your account. See how Fuuud keeps your health memory private.
