What is Vatnode?

Vatnode is an official MCP server that provides VAT validation and EU tax data for AI agents. It allows AI assistants to look up VAT rates, check VAT number formats, and validate VAT IDs against the EU VIES service without leaving the conversation.

How to use Vatnode?

Add Vatnode to your MCP client configuration (e.g., Claude Desktop, Cursor, ChatGPT) by specifying the command npx -y vatnode-mcp and optionally setting the VATNODE_API_KEY environment variable. Free tools (rates, format checks) work without an API key; live validation requires a free vatnode account and key.

FAQ from Vatnode

What is needed for live VIES validation?

A free vatnode API key from vatnode.dev. The free tier includes a monthly request quota.

Are the free tools really offline?

Yes. VAT rates and format data are bundled via the eu-vat-rates-data package and updated daily from the European Commission TEDB.

Which MCP clients are supported?

Vatnode works with any MCP-compatible client, including Claude Desktop, Cursor, ChatGPT (via custom connectors), Continue, and Cline.

Can I use Vatnode without an API key?

Yes. All tools except validate_vat_number are free and work without an API key.

What is the difference between free and paid functionality?

Free tools provide offline VAT rates and format checks. The paid API key unlocks live VIES validation, including company name, address, and an audit-grade consultation number.
