VAT Validator MCP

MCP serverCommerce & finance

This integration lets your AI validate VAT numbers from the EU, UK, and Australia. Once added, your AI can check tax IDs on request and support EU ViDA e-invoicing compliance. That helps keep the tax details you collect accurate before they end up on invoices or in records.

Install VAT Validator MCP

The server’s own address, for the clients that take one directly. Or connect Ahel once and every client you use reads it from one address, with the account kept on Ahel rather than in each client’s config.

Claude Code
claude mcp add --transport http --scope user vat-validator-mcp 'https://vat-validator-mcp-production.up.railway.app'
Run it once in your project, then open /mcp to approve any sign-in the server asks for.
Claude Desktop
https://vat-validator-mcp-production.up.railway.app
Add a custom connector in Settings, paste this address, and approve the sign-in.
Cursor

Open the link and Cursor adds the server at that address.
ChatGPT

From the project's README

As published by ojaskord/vat-validator-mcp in README.md.

AI-powered VAT fraud detection and live VAT number validation for AI agents.

Validates EU, UK, and AU VAT numbers against authoritative live sources and uses AI pattern analysis to detect invoice fraud before payment is authorised. Built for compliance agents, invoice processing workflows, and supplier onboarding pipelines.

What This Solves

VAT fraud costs EU businesses €50bn annually. The most common attack vectors — missing trader fraud, carousel fraud, deregistered entity re-use — share one common signal: a VAT number that looks valid but isn't registered to the entity on the invoice.

Claude and other LLMs cannot reliably check live VAT registration status from training data. This tool calls the authoritative sources directly:

EU VIES — all 27 member states, real-time
UK HMRC VAT API v2 — OAuth2, authoritative
AU ABR — Australian Business Register

Tools

Tool	Free Tier	Use When
validate_vat	50/month	Before approving any EU, UK, or AU supplier invoice -- auto-detects jurisdiction, validates, and runs AI fraud analysis in one call
get_vat_rates	50/month	Before calculating cross-border invoice totals

Add to Your Agent

Claude Code — add to .mcp.json: { "mcpServers": { "vat-validator": { "type": "sse", "url": "https://vat-validator-mcp-production.up.railway.app/sse" } } }

LangChain: from langchain_mcp import MCPClient client = MCPClient( "https://vat-validator-mcp-production.up.railway.app/sse" )

OpenAI Agents SDK: from agents.mcp import MCPServerSse mcp_server = MCPServerSse( params={ "url": "https://vat-validator-mcp-production.up.railway.app/sse" } )
