Real-time IBAN validation for Vercel AI SDK

The `validate_iban` tool runs directly inside your edge functions, providing immediate feedback on account strings. You get the result before the user finishes typing. This MCP Server keeps your UI snappy. Since it runs locally, you don't wait for external API round-trips or loading spinners that kill your conversion rates.

Modulus 97 math inside your streams

Your AI client handles the checksum math automatically. It parses input strings, calculates the Modulus 97, and returns a binary valid or invalid flag. This moves the validation logic out of your backend and into the agent's context. You stop invalid data from hitting your payment processors at the source.

Zero-latency structure checks

The MCP server maps specific country rules against the provided IBAN. It catches length errors and character mismatches immediately. Your application logic stays clean. By offloading these checks to the agent, you handle format errors without writing custom regex for every jurisdiction.

Setup guide

Set up IBAN Bank Validator MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all IBAN Bank Validator tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent IBAN Bank Validator transactions",
});

console.log(text);
await mcpClient.close();

Common questions about IBAN Bank Validator MCP in Vercel AI SDK

Install the MCP client package via npm. Initialize the client with your endpoint and pass the `validate_iban` tool definition directly into your `generateText` or `streamText` function call.

No. The server performs all Modulus 97 calculations locally. Your Vercel AI SDK app stays fast because no network traffic leaves your environment to check the math.

It supports over 80 country formats natively. The tool automatically detects the country code from the IBAN string and applies the correct ISO 13616 length and checksum rules.

The tool returns a clear false status along with the specific reason for failure. You can feed this error back to the user instantly through your UI.

The server only processes the raw string to run checksum math. It never logs your input or stores account numbers, keeping your user data ephemeral and isolated.
