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

Which login do I use?

Usually your PSD-Key or alias and your online banking PIN; a few PSD Banks use the VR-NetKey instead. You enter them in your bank's own web form and confirm with the TAN method you already use.

Does my assistant see my login details?

No. You log in through your PSD Bank's web form. Neither BankingMCP nor your assistant ever sees your PSD-Key, PIN or TAN.

Can my assistant transfer money from my PSD Bank 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.

Which approval method do I need?

SecureGo plus, as in online banking. You confirm the access once when you connect, and again when the consent runs out.

What happens if I want to cut off access?

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

Connect PSD Bank to Windsurf

BankingMCP is an MCP server for your PSD Bank account, whichever of the 16 PSD Banks in the directory it is with. You connect your bank once through its regulated web form and add the MCP address to your assistant. From then on it reads balances and transactions – nothing more.

BankingMCP€5 a month

Short answer

All 16 PSD Banks are in the bank directory with an interface BankingMCP connects through. Your assistant gets balances and transactions, read-only, for €5 a month after a 7-day trial. There is nothing to install. Windsurf reads your PSD Bank accounts through BankingMCP: list accounts, read balances, search transactions. It cannot move money.

Guide: connecting PSD Bank to Windsurf

Two parts, about five minutes: first you share your PSD Bank accounts with BankingMCP, then you add BankingMCP to Windsurf.

Share PSD Bank 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 your PSD Bank and sign in to it in its own web form. Your banking credentials never reach us.

Add BankingMCP to Windsurf

In BankingMCP, add Windsurf as an assistant and copy its personal MCP address.
Add the entry shown here to ~/.config/devin/mcp_config.json, or run devin mcp add bankingmcp followed by your address.
Reload the agent and ask about your accounts.
Ask Windsurf your first question, for example: “What's the balance on my PSD Bank account right now?”

~/.config/devin/mcp_config.json

{
  "mcpServers": {
    "bankingmcp": {
      "url": "https://banking-mcp.com/api/mcp/<your-token>",
      "transport": "http"
    }
  }
}

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

PSD Bank at a glance

The PSD Banks are cooperative banks that work much like direct banks: few or no branches, online banking first. You log in with your PSD-Key and PIN and approve in SecureGo plus, the same app the Volksbanken use.

Each PSD Bank is its own bank with its own bank code. The list below shows all of them with code and BIC.

As of November 2026, from the PSD Banks' online banking guides. Banks change their products; check with the bank for the current state.
