Connect Postbank over MCP in three steps
Create an account
Create a BankingMCP account and start the 7-day free trial. You add payment details at Stripe, and you pay nothing if you cancel within the trial.
Connect Postbank
Choose Postbank and log in through its own PSD2 web form. Your banking credentials never reach us.
Set up your assistant
Add the MCP address to Claude, ChatGPT or another assistant. It picks up the banking tools on its own, and you ask your first question.
Good to know about Postbank
- Search for “Postbank” in the connection form. Postbank operates under 73 bank codes; if its name doesn't find it, your account's bank code will.
- Postbank asks for Postbank ID / FKN at login. You enter them in the bank's own form, not at BankingMCP and not in the chat.
- If you share several accounts at Postbank, your assistant sees all of them. You can add more accounts later with one click.
- Banks ask you to confirm access again after a set period. BankingMCP shows you when the Postbank consent expires; after that you log in once more.

Assistants you can use with Postbank
Each one has its own setup guide. Connect one, or all of them.
Connecting Postbank through regulated bank access
- Read-only. Over MCP your assistant only gets read tools: it can list accounts, read balances and search transactions. There is no payment tool in this connection.
- You log in at Postbank itself. Access runs through finAPI, a PSD2-licensed account information service, and your banking credentials never reach BankingMCP.
- BankingMCP doesn't keep your balances and transactions; it fetches them for each question your assistant asks. Only account details and an access log, kept for 90 days, are stored.
- Every assistant gets its own address. Deactivate one and its access to your Postbank account stops immediately.
Questions about Postbank
- What is MCP?
- The Model Context Protocol is an open standard that lets AI assistants like Claude or ChatGPT use outside tools. BankingMCP makes your Postbank account available as an MCP server, so your assistant looks up balances and transactions directly instead of you uploading bank statements.
- Does BankingMCP support Postbank?
- Yes. Postbank is listed in the bank directory with a XS2A (PSD2) interface, which is how BankingMCP connects. The live check on this page confirms your exact institution.
- Do I need to install an app to use Postbank with Claude or ChatGPT?
- No. BankingMCP runs in the browser on any computer or phone. You connect Postbank once, then add one address to your assistant.
- Does my assistant see my Postbank balance?
- Yes, along with your transactions. Your assistant reads the balance when it asks, together with the time Postbank last delivered it.
- How up to date are my Postbank transactions?
- Your assistant fetches your balance and transactions with every question and gets them as Postbank last delivered them, with a timestamp. If the Postbank consent expires, it only sees the last state until you log in again – and tells you so.
- Can I use Postbank together with other banks?
- Yes. Connect up to 50 accounts across several banks, personal and business. Your assistant answers across all of them, and the price stays at €5 a month.
- What do I need to log in to Postbank?
- Postbank's own login form asks for: Postbank ID / FKN. You enter them at Postbank, not at BankingMCP and not in the chat.
- Does my assistant see my Postbank login?
- No. You log in at Postbank in its own web form. Neither BankingMCP nor your assistant ever receives your PIN, password or TAN.
- Do I need programming skills to use Postbank with Claude or ChatGPT?
- No. You connect Postbank in the browser and copy one address into your assistant's settings. Every assistant has a step-by-step guide.
- Can my assistant transfer money from my Postbank account?
- No. The connection is read-only and has no payment tool. Payments are planned as a separate feature, where you approve every transfer in your own banking app.
Another account at a different bank?
Every bank runs on the same €5 monthly plan. Connect them together and your assistant answers across all your accounts at once.
