Can't I just use the comdirect API?

If you write code, yes. The comdirect API needs a registration, OAuth2 and a TAN for each session. BankingMCP gives your assistant the same accounts without code, and your other banks with them.

The Model Context Protocol is an open standard that lets AI assistants like Claude or ChatGPT use outside tools. BankingMCP makes your comdirect account available as an MCP server, so your assistant looks up balances and transactions directly instead of you uploading bank statements.

Does BankingMCP support comdirect?

Yes. comdirect 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 comdirect with ChatGPT?

No. BankingMCP runs in the browser on any computer or phone. You connect comdirect once, then add one address to ChatGPT.

Does my assistant see my comdirect balance?

Yes, along with your transactions. Your assistant reads the balance when it asks, together with the time comdirect last delivered it.

How up to date are my comdirect transactions?

Your assistant fetches your balance and transactions with every question and gets them as comdirect last delivered them, with a timestamp. If the comdirect consent expires, it only sees the last state until you log in again – and tells you so.

Can I use comdirect 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 comdirect?

comdirect's own login form asks for: Zugangsnummer / Benutzername. You enter them at comdirect, not at BankingMCP and not in the chat.

Does my assistant see my comdirect login?

No. You log in at comdirect in its own web form. Neither BankingMCP nor your assistant ever receives your PIN, password or TAN.

Do I need programming skills to use comdirect with ChatGPT?

No. You connect comdirect in the browser and add one address to ChatGPT. Every assistant has a step-by-step guide.

Can my assistant transfer money from my comdirect 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.

What happens if I want to cut off access?

Each assistant has its own address. Deactivate or remove the one you gave ChatGPT and it stops working immediately, without touching your other assistants.

Guide: connecting comdirect to ChatGPT

Two parts, about five minutes: first you share your comdirect accounts with BankingMCP, then you add BankingMCP to ChatGPT.

Share comdirect with BankingMCP

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.
In BankingMCP, search for “comdirect” and sign in to comdirect in its own web form with Zugangsnummer / Benutzername. Your banking credentials never reach us.

Add BankingMCP to ChatGPT

In BankingMCP, add ChatGPT as an assistant and copy its personal MCP address.
In ChatGPT, open Settings → Security and login and turn on Developer mode.
Open Plugins, click +, name it BankingMCP, paste your MCP address and choose No authentication.
Start a chat, pick BankingMCP under Developer mode and ask your question.
Ask ChatGPT your first question, for example: “What's the balance on my comdirect account right now?”

MCP address

https://banking-mcp.com/api/mcp/<your-token>

This address is an example. You get your own after signing up, and it works like a password.

Good to know about comdirect

comdirect asks for your access number (Zugangsnummer) and PIN. You approve with photoTAN, in the app or on the reader.
Search for “comdirect” in the connection form. comdirect operates under 8 bank codes; if its name doesn't find it, your account's bank code will.
Your assistant doesn't see your comdirect depot: securities, prices and orders stay out. It sees your accounts with their balances and transactions.
If you share several accounts at comdirect, 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 comdirect consent expires; after that you log in once more.

comdirect has an API – why use MCP?

comdirect is one of the few banks with a public API for private customers: you register in your personal area and connect with OAuth2, confirming each session with a TAN. That's built for developers who write their own code.

BankingMCP needs none of that: you log in once, add one address to Claude or ChatGPT, and your assistant reads your comdirect accounts next to your other banks, read-only.

Your assistant doesn't see your comdirect depot: securities, prices and orders stay out. It sees your accounts with their balances and transactions.

Connecting comdirect 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 comdirect 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 comdirect account stops immediately.
