MBH Bank (ex-MKB Bank) Open Banking & API Access

Reaching your MBH Bank (ex-MKB Bank) account data no longer means wrestling with eIDAS certificates or a bank sandbox. open-banking.io gives you PSD2 access to Hungary's MBH Bank through one dashboard covering 2,600+ European banks. Whether you hold a business or personal account, you approve access once and your balances and transactions flow into a workspace only you can decrypt — the service is zero-knowledge and holds nothing but your public key.

MBH Bank was formed from the merger of MKB Bank, Budapest Bank and Takarékbank, and its accounts carry the BIC FHKBHUHBXXX. A single consent stays valid for up to 180 days before you re-authorise.

How to connect MBH Bank (ex-MKB Bank)

Connecting happens entirely in the open-banking.io dashboard — there is no API call, code or key involved.

  1. Sign up for open-banking.io and open the dashboard.
  2. Set an encryption passphrase. Your keys are generated on your own device, so only you can later read your data.
  3. Pick MBH Bank (ex-MKB Bank) from the bank list and choose your account type — business or personal.
  4. You are redirected to MBH Bank's own secure login, where you approve the PSD2 consent directly on the bank's screen. Your credentials never touch open-banking.io.
  5. Your accounts sync back into the dashboard, ready to view.

That's the whole flow — pick, approve, done.

Access your data

Reading MBH Bank data programmatically is an optional step you take after connecting. On the Developers page, create an API key and export a credentials.json — this bundles the API key together with your private decryption key. From there use the CLI:

openbanking accounts
openbanking transactions
openbanking sync

or an SDK, or the REST API. Requests authenticate with the X-Api-Key header, and every response is decrypted locally with your own key. An API key alone only ever returns ciphertext — without your private key, nobody (including open-banking.io) can read it. Note the CLI and SDK only read and sync existing connections; there is no connect command.

All of this runs for roughly EUR 3/month, with no certificate paperwork.

FAQ

Do I need an eIDAS certificate for MBH Bank?

No. open-banking.io is certificate-free — you authorise access on MBH Bank's own consent screen and skip the regulatory paperwork entirely.

Can open-banking.io see my MBH Bank transactions?

No. The service is zero-knowledge and stores only your public key. Data is decrypted on your device with a private key that never leaves it.

Up to 180 days per authorisation. After that you simply re-approve through the dashboard to keep syncing.
