Read-only account access · no payments

We have €48,200 in the business account today. Will that last until the end of the year?

belege.ai · 12 months of incoming and outgoing payments queried

Yes. On average, about €4,100 more comes in each month than goes out on running costs. On top of that, these payments are due before the end of the year:

Nov 10VAT for Q3−€6,830quarterly
Nov 15Liability insurance−€1,186annual
Nov 30Christmas bonus−€9,200like last year

The tightest point is the end of November at about €39,200; by the end of December you're at around €43,300. Shall I break the forecast down week by week?

Example data. Your assistant writes the answer; the transactions come from belege.ai.

What you can use the connection for

Your assistant sees every incoming and outgoing payment in your account, so it can answer questions about your whole business, not just the bookkeeping.

  • Plan your cash flow

    Your assistant spots recurring payments in and out and projects the coming weeks. Just tell it your current balance.

    “Build a 13-week cash-flow forecast from our fixed income and expenses.”

  • Analyze spending

    Costs by merchant, category, or period – and what has changed compared with last year.

    “What did we spend the most on this quarter – and what has become more expensive?”

  • Review subscriptions and contracts

    Running subscriptions, insurance policies, and direct debits at a glance, including price increases and duplicates.

    “Which subscriptions still charge our account – and what do they cost per year?”

  • Keep an eye on incoming payments

    Check whether a customer has paid and see how your revenue develops.

    “Has the €4,760 payment from Müller GmbH come in yet?”

  • Summarize the month

    Income, expenses, and anything unusual as a short overview – for you, your co-founders, or shareholders.

    “Summarize September: income, expenses, biggest items, and anything unusual.”

  • With receipt search

    Find missing receipts

    belege.ai looks for the invoices behind your transactions in your inbox and supplier portals. Your assistant then knows which ones are still missing.

    “Which transactions from September are still missing a receipt?”

Works without the receipt search

Only want to analyze your transactions? A connected bank account is all it takes. You don't need to connect a mailbox, accounting software, or Telegram, and you can add the receipt search later.

    Sign-in and approval happen in belege.ai, not in the chat. Your assistant never sees your PIN, TAN, or password.

  • Encrypted at belege.ai

    belege.ai stores connection details encrypted. Approved transactions are kept on servers in Germany for reconciliation, receipt matching, and MCP.

    Every MCP client signs in via OAuth. You can revoke its access in the API token settings at any time.

Frequently asked questions about VR-Bank Chattengau and MCP

Can I connect VR-Bank Chattengau?

The definitive check happens after sign-in in the secured bank connection flow using your IBAN. This directory entry describes the intended workflow, but it is not a blanket support guarantee for every account, product, or authentication method.

Can I use the MCP just for my transactions?

Yes. A connected bank account is all it takes. You don't need to connect a mailbox, accounting software, or Telegram. Your assistant then works with your transactions, for example for cash-flow planning, spending analysis, or checking incoming payments. If you add the receipt search later, belege.ai matches invoices, surfaces receipt gaps, and prepares the handoff to DATEV or your tax adviser.

Can my assistant see my account balance?

No. belege.ai imports your bank's transactions, not the balance. For a cash-flow forecast, just tell your assistant the current balance; it knows the incoming and outgoing payments from belege.ai.

Does belege.ai store my banking data?

Yes. Reusable connection details are stored encrypted by belege.ai. Approved account and transaction data are synchronized to belege.ai and stored for bank reconciliation, receipt matching, and hosted MCP access.

Does the MCP server run entirely on my Mac?

No. Bank connection and data synchronization use authenticated belege.ai services. The current MCP server is hosted by belege.ai and accesses synchronized data after authentication. We do not currently promise a local-only MCP connection.

Can the MCP client make payments?

No. The current banking workflow reads accounts and transactions. Transfers and other payment initiation are not part of the Banking MCP connection.
