den for households
One memory for the whole house, in the Claude you already use. What the house keeps, how it is added to Claude once, what to say to it, and what it asks before it acts.

den for households is the house's memory behind Claude. You say things to the assistant you already talk to, on a phone or a computer, and the house keeps them: the grocery list, who lives here, who to call, the services and bills, and what happened. Everyone you invite sees the same thing from their own Claude. Nothing is typed twice and nothing gets lost.
#What the house keeps
| Place | What goes there | What you say |
|---|---|---|
| Groceries | The shopping list. Ticked in the shop, cleared when you say you shopped. | "Add milk." "We are out of cat food." "Got everything but the bread." |
| Members | Who lives here, with birthdays and the things worth knowing (an allergy, a school). | "The youngest is allergic to peanuts." "When is the birthday?" |
| Contacts | Who to call: the plumber, the vet, the school, the landlord. | "Who is our electrician?" "The new dentist is on King Street, 020 7946 0011." |
| Services | What the house pays for and when it renews: internet, insurance, subscriptions, with the bill attached. | "The internet went up to 89 a month." "When does the car insurance renew?" |
| Journal | Everything that happened, dated: a repair, a purchase, a meal out, a decision, an appointment. Anything with an amount is also counted. | "The plumber came and charged 180." "We decided to keep the old fridge." "How much did we spend on the car this year?" |
A new kind of thing does not need a new place. Say it, and Claude puts it in the journal. If a list or a table of its own would help, say so, and Claude makes one.
#Adding it to Claude, once
You need an account first: ask for one and a person answers. Then, on a computer:
Sign in to claude.ai, open Customize, then Connectors, and press + to add one.
Give it a name,
den, and paste the address:https://den.pkslabs.com/mcp/householdA den page opens. Sign in and tick Start a new workspace for it. It asks for a short id for the link, what you call the house, your currency and your time zone. That is the setup.
Open the Claude app on any phone in the house, signed in to the same Claude account, and switch den on for the chat.
The people who live with you get their own Claude account and their own den account. You invite them by email from the house, or by telling Claude "add my brother to the house, his email is name@example.com". They join the house, not a company.
If you use Claude Code, the same house is one install away:
claude plugin marketplace add https://den.pkslabs.com/.claude-plugin/marketplace.json
claude plugin install den-household@den-pkslabs-com#What it asks before it acts
- Removing anything. Taking a person off the house, a contact out of the list, or a bill out of the services waits for a yes. Ticking a grocery item does not.
- A day said loosely. "Next Tuesday" is confirmed as a date before it is booked.
- Something private. A matter about one person goes in that person's own place, not the shared journal, and Claude asks which you meant when it is unclear.
Two things it never does: it never keeps a password, a door code or a card number, however it is said, and it does not answer a question about the house from general knowledge. If the house has nothing on it, it says so.
#What is coming up
Dates live on the thing they belong to: a renewal on the service, a birthday on the member, an appointment in the journal. "What is coming up this month?" reads them all. Turn on the daily digest under Tokens and devices and the same list arrives by mail each morning, only on days something is due.
#Everything is yours
Every change keeps its history and who made it, so "who took eggs off the list" has an answer. Anything deleted goes to the trash, where it can be restored. A table downloads as a spreadsheet from its page, and the whole house can be exported as ordinary files. Nothing is locked in a format only den can read.
