Vatnode Mcp

vatnode/vatnode-mcp

Connects Claude and other MCP clients to EU VAT validation through five focused tools. The free tier handles offline lookups: current VAT rates for 45 European countries (pulled daily from the European Commission TEDB), format validation against country regexes, and bulk rate queries across all 27 EU members. Add a free vatnode API key and you unlock live VIES validation that returns company names, addresses, and audit-grade consultation numbers. Runs locally via npx with zero hosted dependencies. Reach for this when you're building invoicing flows, onboarding EU customers, or need to verify VAT numbers without leaving your AI chat session.
