Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "vatnode": {
      "command": "npx",
      "args": [
        "-y",
        "vatnode-mcp"
      ],
      "env": {
        "VATNODE_API_KEY": "your-value",
        "VATNODE_API_URL": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add vatnode --env VATNODE_API_KEY=your-value --env VATNODE_API_URL=your-value -- npx -y vatnode-mcp

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "vatnode": {
      "command": "npx",
      "args": [
        "-y",
        "vatnode-mcp"
      ],

        "VATNODE_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "vatnode": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",

      ],
      "env": {
        "VATNODE_API_KEY": "your-value",
        "VATNODE_API_URL": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

VATNODE_API_KEY secret env
vatnode API key (free tier available at https://vatnode.dev). Required only for the validate_vat_number tool — the four other tools (rates, format checks, country list) work offline without a key.
VATNODE_API_URL env
Override the vatnode API base URL (for self-hosting or staging environments). Defaults to https://api.vatnode.dev.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Common questions

Is Vatnode 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: VATNODE_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 (1.3.0) reached the registry 37 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

vatnode-mcp

Official Model Context Protocol server for [vatnode](https://vatnode.dev) — VAT validation and EU tax data for AI agents.

Lets AI assistants (Claude Desktop, Cursor, ChatGPT, Continue, Cline, …) look up VAT rates, check VAT number formats, and validate VAT IDs against the EU VIES service without leaving the chat.

Free, offline — VAT rates and format checks for 45 European countries, no account needed
Live validation — verify EU VAT numbers against VIES, get the registered company + the VIES consultation number (requires a free vatnode API key; the consultation number is produced once you set your own VAT as requester in dashboard Account details)
Five focused tools — well-described for accurate agent tool selection
Pure stdio, zero hosted dependencies, runs locally via npx

Tools

Tool	Free	Description
`get_country_vat_rates`	✅	Standard / reduced / super-reduced / parking rates + VAT number format for a country
`list_eu_vat_rates`	✅	All 27 EU member states (plus XI for Northern Ireland) at once
`check_vat_format`	✅	Offline syntactic check of a VAT number against the country regex
`list_supported_countries`	✅	All 45 supported countries and which ones support full VIES validation
`validate_vat_number`	🔑	Live VIES validation — returns validity, company name, address, registration date, and (when a requester VAT is set in dashboard Account details) the VIES consultation number

Free tools work fully offline — data is bundled via eu-vat-rates-data and updated daily from the European Commission TEDB.

validate_vat_number requires a vatnode API key. The free tier includes a monthly request quota — get one in 30 seconds.

Install

Claude Desktop

Add to your claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

"mcpServers": { "vatnode": { "command": "npx", "args": ["-y", "vatnode-mcp"], "env": { "VATNODE_API_KEY": "vat_live_your_key_here" } } } }

Restart Claude Desktop. The vatnode tools will appear in the tool picker.

You can omit VATNODE_API_KEY if you only need the free tools (rates, format checks).

Cursor

Settings → MCP → Add new server:

"mcpServers": { "vatnode": { "command": "npx", "args": ["-y", "vatnode-mcp"], "env": { "VATNODE_API_KEY": "vat_live_your_key_here" } } } }

ChatGPT (custom connectors / Apps SDK)

Configure as an stdio MCP server with the same npx -y vatnode-mcp command. See the Apps SDK docs.

Continue / Cline / other clients

Any MCP-compatible client can connect — point it at npx -y vatnode-mcp and (optionally) pass VATNODE_API_KEY via environment.

Get an API key

validate_vat_number requires a vatnode account. The platform also offers things the MCP doesn't expose:

Webhooks for VAT status changes (monitor a customer's VAT continuously)
Bulk validation
National-database fallback when VIES is down
VIES consultation numbers (a timestamped record that the check was made against VIES)
Per-key rate limiting + dashboard analytics

Example session

You: What's the VAT rate in Finland and Germany?

*(Agent calls get_country_vat_rates for FI and DE — free, no key.)*

Agent: Finland's standard VAT is 25.5%, Germany's is 19%. Finland has reduced rates of 14% and 10%; Germany has 7%.

You: Is IE6388047V a valid VAT?

*(Agent calls validate_vat_number — requires API key.)*

Agent: Yes, it's valid. Registered to GOOGLE IRELAND LIMITED at Gordon House, Barrow Street, Dublin 4.

Configuration

Env var	Required	Default	Purpose
`VATNODE_API_KEY`	for `validate_vat_number`	—	API key from https://vatnode.dev
`VATNODE_API_URL`	no	`https://api.vatnode.dev`	Override the API base (self-hosting / staging)

Releasing

Releases are published to npm via Trusted Publishing — no NPM_TOKEN secret, every release signed with npm provenance.

# bump the version in ALL of: package.json, src/index.ts (VERSION),

and server.json (top-level "version" + packages[0].version — the MCP

Registry publish reads server.json and rejects a duplicate version).

Commit, then:

git tag v0.3.2 git push --tags

CI on .github/workflows/release.yml picks up the tag and publishes.
