Your AI does the work. We keep it safe and sound.

No other AI tool gives you this. Your workflow runs in the client you already love, your account stays protected, and you decide what the agent can and cannot do. It is the whole reason to make the switch.

Each Connector lives inside our infrastructure, the same place where your workflow runs. The three things below are already part of it, working quietly in the background so you never have to think about them. Nothing to add, nothing to set up, nothing to worry about.

V8 Isolate01

Each Connector runs inside its own sealed environment.

Each Connector runs inside its own sealed V8 runtime — no access to your files, your system, or other servers. A Connector never sees past its own request.

Kill Switch02

One switch stops every agent. Instantly.

One action deactivates every Connector, revokes every token, and ends every session at once. AI Governance keeps the record.

FinOps per User03

Spending limits that pause instead of surprise.

Every user keeps their own connections and credentials, isolated from everyone else. Anything that would cross your spending limit is held for your approval, not billed.

Three controls, built into the layer your AI connects through.

Curated set · 1 capability

We ship only the actions that matter.

Capability set01 / 01

01

1 capability in this set.

Part of 1 available through IBAN Tools.

  1. 01

    Validate iban

    This capability runs the Modulus 97 checksum calculation on a provided IBAN string to confirm it is mathematically valid. It checks both the structure and the checksum to ensure the account number is correct.

Real work

What teams actually run

01

Payment Processing

Verify bank details before sending instructions to a payment gateway.

02

Data Cleaning

Sanitize and format raw user input from web forms into valid IBAN strings.

03

Error Prevention

Catch invalid account numbers before they cause transaction rejections.

04

Automated Auditing

Run checks on large datasets of bank accounts to ensure structural integrity.

Automate a task

Put IBAN Tools to work on one thing.

Step-by-step automations your AI runs through this Connector: the workflow, the prompts to start with, and the exact capabilities behind each move.

One connector, every AI

IBAN Tools works with the most popular AI clients.

These are the most popular clients, each with a step-by-step guide: one link, set up once, with governance and visibility built in. And because everything runs on the MCP standard, the same connection also works in any other compatible client — nothing to rebuild.

Building your own app? The connector is yours to use.

You don't need a client to put IBAN Tools to work: the same hosted connection plugs into your own applications and agent code, with the same governance on every request. Build with it, chat with it — one connection for both.

Preview access · not provider authentication

The vk_preview_* token belongs to Vinkius preview infrastructure. It lets Claude discover and display the capabilities of IBAN Tools, so you can see the experience inside your AI.

It does not authenticate your account with IBAN Tools. Actions requiring credentials or live account data may not run until you activate the Connector and authorize the service.

Who it's for

Built for the work IBAN Tools owners hand off.

This is built for anyone building automated payment or financial workflows where accuracy is non-negotiable.

  • 01

    Fintech Developers

    They hand off IBAN strings to the agent to ensure data is clean before hitting payment APIs.

  • 02

    Operations Managers

    They use it to verify bulk payment lists to prevent failed international transfers.

  • 03

    Automated Agents

    They use the capability to perform the math they aren't natively capable of doing.

FAQ

Questions IBAN Tools owners ask.

  • 01

    Why can't my AI client just validate IBANs itself?

    LLMs struggle with the complex Modulus 97 arithmetic required for IBANs. They often guess, which leads to invalid numbers being accepted as correct.

  • 02

    What exactly does the Modulus 97 check do?

    It performs a specific mathematical checksum calculation that verifies the structural and mathematical validity of the IBAN string.

  • 03

    Can this MCP handle messy user input?

    Yes, the capability can be used to sanitize strings by removing spaces and verifying the resulting format.

  • 04

    Which AI clients can use this MCP?

    Any MCP-compatible client like Claude, Cursor, Windsurf, or VS Code can use this capability once connected via Vinkius.

  • 05

    Does this capability check for country-specific rules?

    Yes, it verifies the exact alphanumeric patterns and lengths required for different countries.

  • 06

    Does it connect to banks?

    No, it purely validates the mathematical checksum of the IBAN structure.

  • 07

    Is it secure?

    Yes, 100% local evaluation. No data is transmitted.

  • 08

    What countries are supported?

    All official SEPA and international countries that use the standard IBAN format.
