What happens if a country's VAT service is offline?

Yes, the validate_vat_batch capability allows you to pass a list of up to 5 VAT numbers in a single call.

Do I need an API key or registration to use this MCP?

No. VIES is a free public service of the European Commission. every capability in this MCP works without any authentication. The batch capability is limited to 5 numbers per call out of respect for fair use.

Why do some valid VAT numbers return no company name or address?

Member states decide how much data they share through VIES. Belgium, Greece and others return validity only (match score 3 = 'no data returned'). The number is still legally valid. only the trader data is withheld. Use the matchScore legend in validate_vat_details to interpret results correctly.

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.
