Check a UK or EU VAT number against official sources and get the registered name and address
The publisher's own server: UK Data: Compliance and finance checks
Overview
Remote MCP server that lets an assistant check UK or EU VAT numbers against official sources and return the registered name and address.
- What you can do
- Validate a UK or EU VAT number against official sources
- Retrieve the registered business name and address linked to a checked VAT number
- Work within a free daily allowance, with an optional key for higher usage
- When to use it
- Useful when an assistant needs to confirm that a business VAT number is valid, or to pull the registered name and address for a company before invoicing, onboarding or record-keeping.
- Requirements
- A remote streamable HTTP endpoint; no local install or package. No authentication is required for the free daily allowance. An optional Authorization header with a bearer key, obtained from the provider, raises the limit.
Installation
In SourceWeft
- Open UK Data: VAT number checks in the dashboard and add it to a workspace.
- Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/uk.co.reliness%2Fvalidation/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.Other MCP clients
Add this to your client's mcpServers config.
