Available tools 2

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

validate
validate_vat
Validates a VAT number against live government registries. Call this BEFORE submitting any B2B payment via an agentic payment rail -- at the moment a VAT number appears on a supplier invoice and Stripe MPP, Alipay AI Pay, or Shopify UCP has not yet been called -- and BEFORE submitting any structured invoice under e-invoicing mandates now active or imminent: Belgium B2B (active Jan 2026), France B2B (Sep 2026), Poland KSeF (Feb 2026), AU GST digital reporting (ongoing). Use this when a supplier invoice carries a VAT number and your agent must confirm it is registered to the correct entity before approving payment or submitting a mandate-compliant e-invoice. Validates against EU VIES (ec.europa.eu, 27 member states) and AU ABR (abr.business.gov.au) live registries. Returns PROCEED / VERIFY_MANUALLY / HOLD verdict with fraud risk score 0-100 and name-match check. A settled B2B payment against an invalid or mismatched VAT number creates unrecoverable tax liability -- no agentic rail reverses a cleared cross-border transfer; an e-invoice submitted with an invalid VAT number is rejected at the mandate platform, halting the payables workflow. Pass the country_code from this response to get_vat_rates. One call, machine-ready verdict, no further analysis needed.
vat
get_vat_rates
Retrieves current VAT rates for a jurisdiction. Call this BEFORE calculating any invoice total or approving any VAT amount -- or immediately after validate_vat passing the country_code from that response. Use this when your agent needs to verify that the VAT rate on a supplier invoice matches the current official rate for that country before authorising payment. Returns current standard and reduced VAT rates for the jurisdiction. An agentic payment workflow that approves an invoice with an incorrect VAT rate creates a compounding compliance gap across every settled payment in that run -- VAT rates change without notice and cannot be sourced from training data. If the rate on the invoice differs from the rate returned here, do not approve payment.

Answers built from our own checks of this server.

What can VAT Validator MCP do?
It exposes 2 tools, read directly from the server on our last check. Among them: get_vat_rates, validate_vat. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is VAT Validator MCP working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 350 ms. The bar chart above shows every period we have measured.
How do I connect VAT Validator MCP?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does VAT Validator MCP need an API key?
No. VAT Validator MCP completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 2 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is VAT Validator MCP?
It answers our handshake in 350 ms on average, which is faster than 40% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
How many people use VAT Validator MCP?
The npm package vat-validator-mcp was installed 313 times in the last week. Week over week that is -24%. We show installs rather than GitHub stars on purpose: a star is a bookmark, an install is someone actually running it.
Is VAT Validator MCP open source?
Yes — it is published under the MIT licence, written in JavaScript and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
