How do I use Vatlayer with my AI client?

You connect the Vatlayer MCP through Vinkius to your client, such as Claude or Cursor. Once connected, you can use natural language to trigger tax capabilities.

Can this MCP verify company names?

Yes. When you use the validation capability, it retrieves official company details and addresses alongside the VAT status.

Does it support all EU countries?

Yes, the MCP provides access to VAT rates and validation for EU member states.

What do I need to get started?

You will need a Vatlayer Access Key to authenticate your requests through the MCP.

Can it calculate total prices?

Yes, the calculate_price capability handles math for specific amounts and product types based on country-specific VAT rules.

How can I check if a specific EU VAT number is valid and active?

Use the validate_vat capability by providing the VAT number (e.g., LU26375245). The agent will return the validation status along with company name and address details.

Can I get a complete list of VAT rates for all EU member states at once?

Yes, simply run the get_rate_list capability. It will fetch the full set of VAT rates for all 28 EU member states in a single response.

How do I calculate a VAT-compliant price for a specific country?

Waiting for input…

Works with modern AI clients that support MCP, including ChatGPT, Claude, Cursor, and more.

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 · 4 capabilities

Automate a task

Put Vatlayer 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

Vatlayer 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 Vatlayer 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 Vatlayer, so you can see the experience inside your AI.

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