About isvat MCP Server
Empower your AI agent to orchestrate your entire European VAT validation workflow with isvat, the simple and fast API for tax ID verification. By connecting isvat to your agent, you transform complex VAT lookups into a natural conversation. Your agent can instantly verify if a European VAT number is valid without you ever touching a manual lookup tool. Whether you are conducting financial due diligence or managing international invoicing, your agent acts as a real-time compliance assistant, ensuring your tax data is always verified.
The Vercel AI SDK gives every isvat tool full TypeScript type inference, IDE autocomplete, and compile-time error checking. Connect 3 tools through Vinkius and stream results progressively to React, Svelte, or Vue components. works on Edge Functions, Cloudflare Workers, and any Node.js runtime.
What you can do
- VAT Auditing — Verify if any European VAT number is valid and retrieve immediate confirmation status.
- Batch Oversight — Validate multiple VAT numbers simultaneously to maintain strict control over large contact lists.
- Compliance Intelligence — Identify valid tax IDs for businesses across the European Union to assist in financial auditing.
- Operational Monitoring — Check API status to ensure your verification workflow is always operational.
