IBAN Checker for WooCommerce

Prevent invalid IBAN numbers from reaching your payment processor. The plugin validates each IBAN at checkout via the ibanchecker.cash API and blocks submission with a clear error message if the number fails.

define( 'IBANCHECKER_API_KEY', 'iban_...' );

MCP Server for AI Assistants

Model Context Protocol lets AI assistants like Claude use external tools directly, with no copy-paste and no manual API calls.

The ibanchecker MCP server exposes five tools your AI assistant can invoke in real time during any conversation.

Add to Claude Code

The server is hosted at https://mcp.ibanchecker.cash/mcp, so there is nothing to install. One command:

claude mcp add --transport http ibanchecker https://mcp.ibanchecker.cash/mcp

Add to Claude Desktop

Add the following to your Claude Desktop config file (~/Library/Application Support/Claude/claude_desktop_config.json on macOS):

{
  "mcpServers": {
    "ibanchecker": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://mcp.ibanchecker.cash/mcp"]
    }
  }
}

Run locally over stdio (npm)

Prefer running the server on your own machine instead of the hosted endpoint? The package is published as @ibanchecker/mcp. Any MCP client that launches a stdio command can use it directly:

{
  "mcpServers": {
    "ibanchecker": {
      "command": "npx",
      "args": ["-y", "@ibanchecker/mcp"],
      "env": { "IBANCHECKER_API_KEY": "iban_..." }
    }
  }
}

One official client per language

Each one wraps the same five operations with typed results and typed errors, and keeps the untouched response body alongside them, so a field added to the API later is reachable without waiting for a client release.

A malformed IBAN comes back as a result with valid set to false, never as a thrown error. All six are free and MIT licensed.
