Vatnode MCP runs on your own machine — the client starts it, so there is no endpoint to ping. 115 installs a week from npm. Last commit 12 Aug 2026.
Official MCP server: EU VAT validation via VIES, plus offline rates and format checks.
Today is the operative word: we check Vatnode MCP every 15 minutes and re-read its code on every release. Watch it and you find out the day that stops being true.
This server runs on your own machine — install it with the package manager and the client starts it for you. Package name taken from the official registry entry.

This one needs environment variables set before it will start:
VATNODE_API_KEY (vatnode API key (free tier available at https://vatnode.dev). Required only for the validate_vat_number tool — the four other tools (rates, format checks, country list) work offline without a key.), VATNODE_API_URL (Override the vatnode API base URL (for self-hosting or staging environments). Defaults to https://api.vatnode.dev.).
The author declared them in the registry entry; get the values from the project itself.
