OpenIBAN MCP — validate an IBAN's checksum + bank code and resolve the

Part of Pipeworx — an MCP gateway connecting AI agents to 1476+ live data sources.

Tools

Tool Description

validate_iban Validate an IBAN: check its checksum and (where supported) its bank code, and resolve the bank name, BIC, and city. Returns whether the IBAN is structurally valid plus bank details when available. Best coverage for EU/DACH banks (DE, NL, BE, CH, AT, LU); for other countries the checksum is still validated but bank details may be empty. IBANs with spaces are accepted (e.g. "DE89 3704 0044 0532 0130 00").

suggest_iban Suggest corrected IBANs for a possibly-mistyped IBAN. Returns a list of candidate IBANs with validity and bank name/BIC. Coverage is limited; if no suggestions are available this returns an error field.

Quick Start

Add to your MCP client (Claude Desktop, Cursor, Windsurf, etc.):

{
  "mcpServers": {
    "openiban": {
      "url": "https://gateway.pipeworx.io/openiban/mcp"
    }
  }
}

What this endpoint actually serves

tools/list at https://gateway.pipeworx.io/openiban/mcp returns the tools in the table above plus the shared Pipeworx meta-tools — ask_pipeworx, discover_tools, search_within, remember/recall and the rest of the gateway-wide set. So the tool count you see is larger than this table: a single-pack endpoint currently lists roughly 30 shared tools alongside the pack's own. The connection's initialize response states its exact scope, and is the authoritative answer for a given day.

This is deliberate, not multiplexing by accident. The meta-tools are what let a scoped connection answer a question this pack does not cover — via ask_pipeworx, which routes across the whole catalog — without you adding a second MCP server. There is currently no way to mount a pack endpoint without them; if the extra schemas cost you more context than the routing is worth, connect to the full gateway once rather than to several pack endpoints.

Or connect to the full Pipeworx gateway to get every pack's tools listed directly, instead of just this one's:

{
  "mcpServers": {
    "pipeworx": {
      "url": "https://gateway.pipeworx.io/mcp"
    }
  }
}

Both URLs reach the same gateway and the same 1476+ data sources. The only difference is which pack's tools are listed directly; ask_pipeworx reaches all of them from either one.

Using with ask_pipeworx

Instead of calling tools directly, you can ask questions in plain English — this works on the pack endpoint above as well as on the full gateway:

ask_pipeworx({ question: "your question about Openiban data" })

The gateway picks the right tool and fills the arguments automatically.
