VAT Validator MCP

Overview

VAT Validator MCP is a Model Context Protocol server that validates EU, UK, and AU VAT numbers for AI agents while maintaining EU ViDA e-invoicing compliance. It exposes VAT validation as callable tools, enabling AI assistants to integrate tax compliance checks directly into their workflows without manual data transfer.

Run VAT Validator MCP via the hosted endpoint at https://vat-validator-mcp-production.up.railway.app or locally using npx -y vat-validator-mcp. You'll need to set ANTHROPIC_API_KEY in your environment. The current release is v2.0.30 under the MIT license, with source code available at OjasKord/vat-validator-mcp on GitHub.

VAT Validator MCP is listed in the AI & Agents category and works with MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain this server, claim this listing to verify your ownership and keep information current.
