FAQ from Vat Validator MCP

How does Vat Validator MCP differ from basic VAT validation?

Basic validation only confirms a VAT number is real. The server's AI tools catch fraud signals that raw validation misses, such as mismatched company names or newly registered shell companies.

What runtime or API key is required?

The free tier requires no API key — just connect and go. Paid plans (Pro and Enterprise) are available at kordagencies.com.

Where do validation results come from?

Results are sourced directly from live official government registries: EU VIES, UK HMRC, and Australian ABR. The server does not log or store your query content.

What are the known limits or downtime risks?

Free tier is limited to 20 calls per month. The EU VIES registry experiences periodic downtime; the server includes explanatory error messages and retry guidance.

How is the server accessed and authenticated?

Standard MCP URL-based configuration. No authentication is needed for the free tier. Paid plans provide higher call volume limits and batch validation access.
