Connect your AI to vaulink

vaulink has a connector for your own AI. Claude is the example here, but any AI client that supports remote MCP servers can use it. The AI reads your accounts and balances and can propose changes. Nothing that moves money is applied until you confirm it in the app.

Enter the code
Claude opens a vaulink page that asks for a code. Tap "Get code" in the app, enter the code on that page, and press "Allow access". The code is valid for ten minutes.
Ask about your accounts
Ask about your accounts
Ask Claude about your accounts. The first answer appears after the app has uploaded your accounts: open vaulink once while signed in, or tap "Refresh data now" on that screen.

Requirements

An iPhone with the vaulink app, signed in. In guest mode nothing is sent.
An active vaulink PRO subscription. Without it the server answers 403 "PRO subscription required".
An AI client that supports custom remote MCP connectors.
Some changes need a recent app (2.3 build 41 or newer). With an older app the server refuses them and says why.

Tools

Read tools only return data. Every write tool puts a request in a queue. The app picks the queue up the next time you open it. Your client lists the tools that are switched on for your account; a few are enabled gradually.

Import

Confirmation on the phone

Changes that move money or cannot be undone (balances, deposits, trades, credit limits, loan payments, archiving, operations, cashback) always open a confirmation sheet in the app. This cannot be switched off.
Other changes (rename, group, restore, new account or category) are also confirmed by default. In the app you can allow some of these to apply without a sheet.
A rejected request is not applied. Ask the AI for the status with get_command_status.

Never leaves your phone

~~Transactions~~

The phone uploads only account names, types, currencies and balances, groups, the credit limit of credit cards, and category names. Transactions are never sent.
Extra data is closed by default: account details (deposit, card, loan terms) and balance history are separate switches, and the AI sees them only when they are on and shared.
The AI you connect receives what it reads. That data goes to that AI’s developer and falls under its rules.
A statement file sent to import_statement is processed in memory and not stored.
To disconnect, open Profile → Links → Your own AI → Close the link. This revokes all access and keys and erases the copy of your accounts on the vaulink server. Removing the connector in Claude alone does not tell vaulink, so use the app. You can also revoke a single key on the same screen.

Known limits

Changes are not instant. They apply when you open vaulink on the phone. A queued change expires after 7 days, and recorded operations after 24 hours.
market_buy and market_sell change the position on the investment account but do not take money from or add money to another account. Only the optional broker commission is charged to the account you name. To reflect the cash, change that account’s balance separately with set_account_balance, which needs its own confirmation.
A request already in the queue cannot be withdrawn through the connector. Decline it on the phone.
Balances are the ones the phone last uploaded. The AI sees when they were updated and is told that a balance older than 7 days may be out of date.
Limits: 50 waiting changes per user, 200 requests per 10 minutes, 5 statement imports per minute (file up to about 650 KB).
