What the Claude Grasshopper Bank connector changes for your finances
Instead of exporting statements and building a spreadsheet, you ask Claude a question about your money the way you would ask a bookkeeper. It reads your Grasshopper accounts and posted transactions itself and answers in the conversation: how much went on client dinners last month, which software subscriptions the business pays for, what the balance looks like today.
A spending breakdown without a spreadsheet. The founder of a small agency wants to know where last quarter's money went. transactions_list returns the transactions, accounts_list the balances and account types, and Claude groups the spending by category and vendor.
A view of what is already scheduled. Before a slow month, a business owner checks which payments are queued. scheduled_transfers_list returns one-time and recurring scheduled transfers, so Claude can list who gets paid and when.
The right statement, located. An accountant asks for the statements from the first quarter. documents_list finds the periodic statements, and Claude hands back a link that opens each one in online banking after you sign in.
What it does not do: the platform behind the connector says the assistant can only read, never move money, so no transfer, payment or account change happens through Claude. Pending transactions do not show up, only posted ones, and Claude cannot display a full statement inside the chat. Nothing runs by itself either: there is no alert when a large payment clears. That kind of monitoring belongs to an automation tool, a different job described from the Integrations hub.
The vocabulary in one minute
Five words you will see while connecting your bank.
- Connector
- The link you set up once between Claude and an account you already hold, so Claude can consult it while it answers you.
- Tool
- One named action a connector gives Claude. Claude picks the tools it needs by itself; the directory lists each one by its name.
- Authorization
- The bank's own sign-in screen, where you hand Claude the access it will use. Given once per person, and you can take it back.
- Approval
- The confirmation Claude waits for before it goes ahead with a step that touches your account, shown in the chat at that moment.
- MCP
- The shared standard connectors are built on: it is what lets an assistant like Claude talk to an outside service such as your bank.
Connect Grasshopper Bank to Claude in three steps
- 01
Find the connector
Open Claude's settings, go to Customize then Connectors, and look for Grasshopper Bank. On a Team or Enterprise workspace, an Owner or Primary Owner has to enable the connector before each member can sign in with their own banking login.
- 02
Sign in to your bank
Click Connect. Then sign in to the bank in the window it opens: that sign-in is run by the bank, not by Claude. If the connection stops working, Disconnect and connect again.
- 03
Review the bank's screens
Read the authorization screen before you accept: it belongs to the bank, not to Claude, and it sets what the access covers. You can withdraw it later from the bank side too.

What Claude reads (6)
6 toolsSix tools that consult your accounts without moving or changing anything.
accounts_list
Asks you firstRetrieves your accounts with their balances, status and account type, which is the starting point for almost any question about where you stand.
documents_list
Finds your monthly and periodic statements. Claude sees what each document is and when it was issued, then gives you a link to open it.
external_accounts_list
The bank's FAQ mentions it only through linked external accounts: those fully verified appear, those still under verification do not. It sits on the read side because the platform states, in general terms, that the assistant only reads.
products_list
Lists the products your bank offers for account opening, which lets Claude answer questions about what else the institution could do for you.
scheduled_transfers_list
Returns transfers already scheduled on your accounts. That covers one-time payments as well as recurring ones, each with its recipient, so Claude can lay out what is about to leave and when.
transactions_list
Asks you firstBrings back transactions from one account or several, the raw material for any spending analysis, chart or monthly comparison Claude prepares.
What Claude asks before it acts
By default, Claude stops and asks for your go-ahead before any action it would carry out on an account for you. On top of that, the bank's platform guide shows dialog boxes asking for access to your account data and your transaction data, where you choose to allow once or always.
The platform also says users must explicitly authorize access to their data for each new chat session. On Team and Enterprise, workspace owners decide whether members may let some actions through without being asked every time, and they can restrict what a connector may do for the whole organization. Claude works with your banking rights, nothing more. And if your online banking is locked, the connector stops working as well, until the bank unlocks the account.
Which plans it is available on
None of the 819 sheets in the official directory shows plan availability. Connector by connector, that answer is published nowhere: a real gap in the catalogue.
The general rule is published: remote connectors are open to all users on Claude, Cowork, Claude Desktop and mobile. On Team and Enterprise, an Owner or Primary Owner enables a connector for the organization before members connect. The bank's platform documentation says something narrower, and even contradicts itself; the limits section sets it out. For the live status, the Grasshopper Bank sheet in the official directory is the place to check.
Where the Claude Grasshopper Bank connector stops
A connector is not an automation. Claude calls these tools while it answers you; nothing starts on its own when a payment clears.
Only the bank's platform provider documents this connector; Claude's help center has no article on it. A sheet that shows nothing but reading is an observed floor rather than a promise, since an administrator can open actions that appear on no public sheet, and the partner badge is not a security audit: Anthropic says on every sheet that it neither picks the tools a publisher exposes nor guarantees how they behave. Connect it only if you trust the publisher.

What this page followsNo side settles it. The platform's two pages disagree with each other, and both describe the custom connector route, while Anthropic's rule covers connectors in the directory. Check the Grasshopper Bank sheet in the directory while signed in to your own account.
