What is the VAT Tax Validator MCP Server?
Validating a European VAT number or a corporate Tax ID requires complex, country-specific mathematical algorithms. LLMs hallucinate these checks, which can lead to agents generating illegal invoices or fraudulent contracts. This MCP solves that entirely.
The Superpowers
- Local Algorithmic Checking: Verifies the format and checksum of VAT numbers across all EU countries natively in V8.
- B2B Billing Shield: Ensures that before your agent creates an invoice in Stripe or Xero, the tax ID is structurally valid.
Built-in capabilities (1)
Pass the tax number string and the engine performs offline mathematical validation against the correct country format. Validates European and international VAT (Value Added Tax) numbers offline using strict country-specific algorithms
Why Vercel AI SDK?

Frequently asked questions
Does it connect to VIES API?
No, it checks the mathematical format (checksum) local. This guarantees sub-millisecond validation without network dependency.
Which countries are supported?
All European Union member states (GB, DE, FR, IT, ES, etc).
Does it validate corporate names?
No, it purely validates the mathematical format of the VAT number itself.
How does the Vercel AI SDK connect to MCP servers?
Import createMCPClient from @ai-sdk/mcp and pass the server URL. The SDK discovers all tools and provides typed TypeScript interfaces for each one.
Can I use MCP tools in Edge Functions?
Yes. The AI SDK is fully edge-compatible. MCP connections work on Vercel Edge Functions, Cloudflare Workers, and similar runtimes.
Does it support streaming tool results?
Yes. The SDK provides streaming primitives like useChat and streamText that handle tool calls and display results progressively in the UI.
createMCPClient is not a function
Install: npm install @ai-sdk/mcp
