Common questions

Is Eurovalidate MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: EUROVALIDATE_API_KEY

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Python (uv) on your computer.

What can I use instead?

EuroValidate MCP Server

MCP (Model Context Protocol) server for EuroValidate — lets Claude, ChatGPT and any MCP-capable agent validate EU VAT numbers (VIES), IBANs and EORI customs numbers, look up company data, and fetch VAT rates through one reliable REST API.

Why

Validating European business data normally means juggling five fragmented government services: the VIES SOAP API (which times out constantly — Germany alone generates 95% of its errors), the EC EORI endpoint, HMRC, GLEIF, and national registries. EuroValidate wraps them into one cache-first JSON API with per-country circuit breakers and graceful degradation — and this MCP server exposes it to LLM agents as ready-to-use tools.

Tools

Tool	What it does
`validate_vat`	Validate an EU/UK VAT number via VIES/HMRC — returns validity + registered company name & address (where the member state exposes it) + confidence level
`validate_iban`	Validate an IBAN (offline MOD-97) and resolve bank name + BIC
`validate_eori`	Validate an EORI customs number (EU / GB / XI Northern Ireland)
`lookup_company_by_lei`	Company data by Legal Entity Identifier (GLEIF)
`lookup_company_by_vat`	Company data by VAT number — fallback for DE/ES where VIES hides names
`get_vat_rates`	Current VAT rates for an EU country
`check_service_status`	Live health of VIES (per country), EORI, HMRC, GLEIF — no API key needed

Setup

Get a free API key (100 requests/month, no credit card) at eurovalidate.com.
Add the server to your MCP client:

Claude Desktop / Claude Code

"mcpServers": { "eurovalidate": { "command": "uvx", "args": ["eurovalidate-mcp"], "env": { "EUROVALIDATE_API_KEY": "your_api_key" } } } }

Claude Code one-liner:

claude mcp add eurovalidate -e EUROVALIDATE_API_KEY=your_api_key -- uvx eurovalidate-mcp

Any other MCP client

Run over stdio:

EUROVALIDATE_API_KEY=your_api_key uvx eurovalidate-mcp

Or install permanently: pip install eurovalidate-mcp → eurovalidate-mcp.

Example prompts

*"Validate VAT number DE811569869 and tell me the company behind it"*
*"Check if this IBAN is valid and which bank it belongs to: DE89 3704 0044 0532 0130 00"*
*"Is VIES down for Germany right now?"*
*"What's the VAT rate in Portugal?"*
*"Validate the VAT numbers of these 5 suppliers before I invoice them"*

Notes for agents (and humans)

Germany and Spain never return company name/address over VIES (data-protection law) — use lookup_company_by_vat as a fallback.
Greece is EL in VIES but GR in ISO 3166 — both are accepted.
Every response carries confidence: HIGH|MEDIUM|LOW|UNKNOWN and the upstream source, so agents can reason about data freshness when a government service is down.
Free tier: 100 requests/month. Paid plans from €19/mo (500,000 requests/month) at eurovalidate.com.

Agent Skill

skills/eu-business-validation/SKILL.md is a portable Agent Skill that teaches an agent *when* to validate, how to read status/confidence correctly (e.g. unavailable ≠ invalid), the DE/ES/EL/XI gotchas, and how to write checkout/KYB code that never blocks a sale when VIES is down. It works with this MCP server or falls back to plain REST calls.

# Claude Code (personal skills)

mkdir -p ~/.claude/skills && cp -r skills/eu-business-validation ~/.claude/skills/

Claude plugin

This repository is also a Claude plugin bundle (.claude-plugin/plugin.json): it installs the skill above plus this MCP server, pinned to eurovalidate-mcp==0.1.1 and launched with uvx. On install you are asked for your EuroValidate API key; it is stored in Claude's secure credential store and passed only to the MCP server as EUROVALIDATE_API_KEY.

Data and network

The MCP server and the skill send only the identifiers you ask to check (VAT, IBAN, EORI, LEI numbers or a country code) to https://api.eurovalidate.com, together with your API key in the X-API-Key header. check_service_status sends no identifiers and needs no key.
Nothing else is read from your machine or sent anywhere else. No telemetry.
EuroValidate in turn queries public government services (EU VIES, EC EORI, UK HMRC, GLEIF) and caches results (VAT/EORI 24 h, IBAN 1 h). See the privacy policy and terms.
uvx downloads the eurovalidate-mcp package from PyPI on first run.
