OneHaus is now available in ChatGPT, Claude and Claude Code

OneHaus Team2026-06-114 min read

Yesterday, OneHaus arrived in the browser. Today it goes somewhere no household app has any business being: inside the conversation you were already having.

OneHaus now connects to ChatGPT, Claude and Claude Code. Ask what's on this week, add milk to the shopping list, move the dentist appointment, or check when the car's MOT is due, all in plain language, from the assistant you already talk to every day. No app switch, no copy and paste. Say it, and it's done.

One Sentence Away From Done

Once connected, your assistant can see and update your real OneHaus household, the same one on your iPhone and at onehaus.app. That means everyday admin becomes part of whatever conversation you're already in:

  • Tasks and chores: "What's due today?", "Add take out the bins", "Assign the dishwasher to Sam."
  • Calendar: "What's on this weekend?", "Add dentist on Thursday at 3pm", "Move parents evening to next week."
  • Shopping lists: "What's on the list?", "Add milk, eggs and coffee", "Mark bread as bought."
  • The rest of the house: contacts, pets, vehicles, appliances, documents and subscriptions. "When is the dog due for worming?", "What's the model of our washing machine?", "What subscriptions do we pay for?"
  • A summary on demand: "Give me a rundown of what needs attention this week."

You're mid-conversation planning the weekend and remember the school forms? One sentence, and it's a task with a due date, assigned, synced to everyone's phone. That's the whole feature.

How It Works, and Why It's Safe

OneHaus speaks MCP, the open standard AI assistants use to connect to outside tools. There is exactly one thing to know:

https://mcp.onehaus.app

Add that address to your assistant as a custom connector, then sign in with your OneHaus account when prompted. Your assistant handles the secure sign in for you, so you never paste a password or an API key into a chat box.

You stay in control:

  • Your assistant asks for permission to view your household and to make changes on your behalf, and most assistants confirm before changing anything.
  • It can only ever act on the household tied to your OneHaus sign in. Access follows your account, nothing more.
  • Disconnect at any time by removing the OneHaus connector in your assistant's settings.

Works Where You Already Talk

  • ChatGPT: add OneHaus as a custom connector. Custom connectors are a paid ChatGPT feature, and some plans need developer mode switched on.
  • Claude: connect on the web or desktop. Adding connectors is available on paid Claude plans.
  • Claude Code: yes, really. Add OneHaus as an MCP server and manage the household without leaving the terminal.
  • Other MCP tools: anything that speaks MCP can connect the same way.

WhatsApp support is coming soon. And connecting is rolling out gradually, so if your household can't connect yet, it's on the way.

Same Household, Now With a Voice

This is the third leg of the same stool. iPhone in your pocket, browser at your desk, and now the assistant you think out loud with. They all share one household and one source of truth.

Ask Claude to add eggs to the shopping list and they're on your partner's phone before you finish the conversation. Tick a chore off in the app and your assistant knows it's done. Every change syncs in real time, in every direction.

How to Get Started

  1. Open your assistant's connector settings and add https://mcp.onehaus.app as a custom connector.
  2. Sign in with your OneHaus account and approve access.
  3. Ask for something. "What needs attention this week?" is a good first question.

The connection guides walk through the exact steps for each assistant. New to OneHaus? Every plan starts with a free 7-day trial, no card needed.

Frequently Asked Questions

Do I need a paid ChatGPT or Claude plan?

For the assistant side, usually yes: custom connectors are a paid feature in both ChatGPT and Claude, and their options change over time, so check your assistant's connector settings for the latest. On the OneHaus side, there's nothing extra to buy.

Does this cost extra on top of my OneHaus subscription?

No. One household subscription covers everyone in your home on every platform: iPhone, web, and connected AI assistants.

What can my assistant actually see and do?

Exactly what your OneHaus account can: view your household's tasks, calendar, lists and records, and make changes when you ask it to. It asks for both permissions when you connect, and you can disconnect at any time from your assistant's settings.

Which assistants are supported?

ChatGPT, Claude on web and desktop, Claude Code, and any other tool that supports MCP connectors. WhatsApp support is coming soon.

Your Home, In Every Conversation

Household admin has always had one real cost: switching to it. Opening the app, finding the list, typing it in, getting back to what you were doing. Now the gap between "we should sort that" and "it's sorted" is one sentence long.

Connect your assistant, or start with the iPhone app and the browser and add the connector when you're ready.
