Ibanchecker MCP Server

Ibanchecker MCP server exists for a simple reason — assistants are far more useful when they can act on Ibanchecker directly instead of describing what you should do. IBAN validation, extraction, format specs and BIC/SWIFT lookup tools for AI assistants.

What you get

MCP (Model Context Protocol) server for ibanchecker.cash. Gives AI assistants like Claude five finance tools backed by the ibanchecker.cash validation engine:

Setting it up

Being a remote server, there is no local install. You register the endpoint with your client, authorise it once, and the tools appear.

What the assistant can call

Once Ibanchecker is connected, these are the calls the assistant has available:

• Authorization — Bearer / x-api-key header (remote mode)

Configuration and credentials

You will need one environment variable: IBANCHECKER_API_KEY. The server will not start without them, which is usually why the tools fail to appear on a first run. Keep credentials in your client's env block or a secrets manager rather than in a file you might commit.

Before you rely on it

• Your data travels to the provider's service, so the usual questions apply about what you send and what they retain.
• Missing credentials fail quietly in some clients — if no tools show up, check the environment block first.
• MCP clients confirm each tool call by default. Leave that on until you have watched what the ibanchecker mcp server does with a few real requests.

Choosing this one

Plenty of developer tooling servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Ibanchecker's toolset — Authorization — is a fair guide to whether it matches your workflow. It is maintained by koraykoylu; worth a glance at recent repository activity before you build anything load-bearing on it.
