Automated IBAN checks for Mastra AI agents

Embed `validate_iban` as a critical step in your agent workflows. If the check fails, your agent can immediately ask the user for a correction. This prevents downstream errors in your payment pipelines. You build a gate that only lets valid, mathematically sound account numbers through to your treasury system.

Conditional branching based on IBAN validity

Your Mastra AI agents use the tool output to make real-time decisions. If a check returns invalid, trigger an automated retry or escalate to a human agent. It removes the guesswork from your agent's decision loop. You define the path, and the agent follows the logic based on the hard math of the checksum.

High-speed local execution for agents

The server runs locally, meaning your agents don't stall waiting for remote validation. It processes the Modulus 97 math in milliseconds. This fits perfectly into your high-volume transaction handlers. You get the speed of local code with the intelligence of an agent-driven framework.

Setup guide

Set up IBAN Bank Validator MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All IBAN Bank Validator tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "iban-bank-validator-mcp-client",
  servers: {
    "iban-bank-validator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "IBAN Bank Validator Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to IBAN Bank Validator tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent IBAN Bank Validator transactions"
);
console.log(result.text);

Common questions about IBAN Bank Validator MCP in Mastra AI

Add the server to your agent configuration. Once registered, spread the `validate_iban` tool into your agent's toolset and use it as a conditional step in your workflow.

Yes. If the tool reports a validation failure, you can set up a branch in your workflow to notify the user and prompt them to re-enter their details.

Regex only checks format. This server performs the full Modulus 97 checksum, which catches transposition errors that simple string matching would miss entirely.

You can wrap the tool call with manual approval flags. If the validation fails, the agent pauses for a human to review the input before proceeding.

The tool executes in a secure, ephemeral process. It performs the math in memory and discards the IBAN string immediately after the check, ensuring no persistence of your data.
