Connect Commerzbank to Windsurf

This guide gives Windsurf read-only access to your Commerzbank account. You sign in to Commerzbank once in its own web form, add BankingMCP to Windsurf, and ask about balances and transactions. No app, no code.

BankingMCP€5 a month

Short answer

Yes, Commerzbank works. It is in the bank directory BankingMCP connects through, via XS2A (PSD2). Your assistant gets your balance and transactions, read-only, for €5 a month after a 7-day free trial. Nothing to install. Windsurf reads your Commerzbank accounts through BankingMCP: list accounts, read balances, search transactions. It cannot move money.

Guide: connecting Commerzbank to Windsurf

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

Share Commerzbank with BankingMCP

  1. 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.
  2. In BankingMCP, search for “Commerzbank” and sign in to Commerzbank in its own web form with Benutzername/Teilnehmernummer. Your banking credentials never reach us.

Add BankingMCP to Windsurf

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

Commerzbank, Ava and MCP

Commerzbank has its own AI avatar, Ava, in its banking app since April 2025: it orders and blocks cards and changes limits, inside Commerzbank's app. There is no Commerzbank MCP server and no API for private customers.

BankingMCP brings your Commerzbank accounts into Claude, ChatGPT or another assistant, next to your other banks. Former Dresdner Bank accounts are Commerzbank accounts today and connect the same way.

As of November 2026, from Commerzbank's help pages and its press release on Ava (April 2025). Banks change their products; check with the bank for the current state.

What you can ask Windsurf about Commerzbank

  • “What's the balance on my Commerzbank account right now?”
  • “How much did I spend on groceries last month?”
  • “Which subscriptions are still charging my Commerzbank account?”
  • “Did both tenants pay their rent this month?”

Connecting Commerzbank 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 Commerzbank 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 Commerzbank account stops immediately.

Questions about Commerzbank

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 Commerzbank account available as an MCP server, so your assistant looks up balances and transactions directly instead of you uploading bank statements.
Does BankingMCP support Commerzbank?
Yes. Commerzbank 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 Commerzbank with Windsurf?
No. BankingMCP runs in the browser on any computer or phone. You connect Commerzbank once, then add one address to Windsurf.
Does my assistant see my Commerzbank balance?
Yes, along with your transactions. Your assistant reads the balance when it asks, together with the time Commerzbank last delivered it.
How up to date are my Commerzbank transactions?
Your assistant fetches your balance and transactions with every question and gets them as Commerzbank last delivered them, with a timestamp. If the Commerzbank consent expires, it only sees the last state until you log in again – and tells you so.
Can I use Commerzbank 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 Commerzbank?
Commerzbank's own login form asks for: Benutzername/Teilnehmernummer. You enter them at Commerzbank, not at BankingMCP and not in the chat.
Does my assistant see my Commerzbank login?
No. You log in at Commerzbank in its own web form. Neither BankingMCP nor your assistant ever receives your PIN, password or TAN.
Do I need programming skills to use Commerzbank with Windsurf?
No. You connect Commerzbank in the browser and add one address to Windsurf. Every assistant has a step-by-step guide.
Can my assistant transfer money from my Commerzbank 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 Windsurf and it stops working immediately, without touching your other assistants.
