Validate VAT numbers, look up VAT rates and review past checks and plan hits in Vatstack.
The publisher's own server: Ably MCP by usefulapi
Hosted Vatstack server that lets an assistant validate VAT numbers, look up VAT rates by country or IP, and review past checks and plan usage.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
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/io.usefulapi%2Fvatstack/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.Add this to your client's mcpServers config.

}Use your Vatstack account from Claude, Cursor, or any MCP client. Check VAT numbers against government registers, look up VAT rates, and read plan hit usage. Hosted, no local install: connect with your own credentials.

https://vatstack.usefulapi.io/mcp.claude mcp add --transport http vatstack https://vatstack.usefulapi.io/mcp, then run /mcp to log in.Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Vatstack credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/vatstack/
On first connect you provide a Vatstack secret key from your Vatstack dashboard, under your API keys. Use the secret key, not the public key. The server validates it and stores it per user. No keys go in config files.
read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.
Each paid plan covers this server only. Ask your AI to run vatstack_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with vatstack_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with vatstack_upgrade before then undoes the cancel. Or write to [email protected].

100% of the applicable checks met
How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.
