VIES VAT Validation + Meta Muse

Validate EU VAT numbers via the European Commission VIES (VAT Information Exchange System) REST API. Confirms that a VAT number is registered for intra-Community trade and returns the trader name and address when the member state exposes them.

Prerequisites

See the full setup instructions baked into the connector (visible in the in-app store when you select the connector). The required environment variables for this connector are:

(none — public API)

Step 1 — Get credentials

Use for B2B invoice compliance: before issuing an intra-EU invoice without VAT, confirm the buyer's VAT number is valid via this adapter.

Country codes: ISO 3166-1 alpha-2, plus EL for Greece and XI for Northern Ireland. Common codes: DE, AT, FR, IT, ES, NL, BE, PL, DK, SE, FI, IE, PT, CZ, HU, RO.

Format: VAT number must NOT include the country code prefix (e.g. for DE123456789 pass countryCode='DE' and vatNumber='123456789').

Response: valid: true/false, plus name and address when provided by the member state. Some countries (DE, ES) do not return name/address for privacy reasons — in that case only valid is authoritative.

…(continued in the in-app connector instructions)

Step 2 — Install the adapter

curl -fsSL https://raw.githubusercontent.com/HelpCode-ai/anythingmcp/main/docker-compose.quickstart.yml -o docker-compose.yml
printf 'JWT_SECRET=%s\nENCRYPTION_KEY=%s\n' "$(openssl rand -hex 32)" "$(openssl rand -hex 32)" > .env
docker compose up -d

Step 3 — Add the connector in Muse

Your server URL: in AnythingMCP, open MCP Servers → the server this connector is on, and copy its URL (https://cloud.anythingmcp.com/mcp/…). Use it wherever this guide shows YOUR_SERVER_ID.

Muse adds remote MCP servers as custom connectors and signs in to them with OAuth.

  1. In Muse, open Settings → Connectors and choose Add custom connector.
  2. Paste the MCP server URL https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID.
  3. Muse opens the AnythingMCP sign-in page: sign in and approve access.
  4. In a chat, ask Muse for something that needs the VIES VAT Validation tools.

You can also set it up from a chat, on the web, in the iOS and Android apps or in WhatsApp. Send Muse this message:

Create a Custom Connector for a new remote MCP server, then connect to it:
Name: AnythingMCP
Transport: remote streamable HTTP
URL: https://cloud.anythingmcp.com/mcp/YOUR_SERVER_ID
Auth: OAuth

Self-hosting? Use your instance's public HTTPS address instead of https://cloud.anythingmcp.com. Muse connects from Meta's cloud, so localhost does not work.

FAQ

Where is Muse available? Meta currently offers Muse in the US and Canada, on the web, in the iOS and Android apps and in WhatsApp.

Does Meta review this connector? No. Meta doesn't review custom connectors. Muse sees only the tools you switched on for this MCP server in AnythingMCP, and you can disconnect it anytime under Settings → Connectors.
