Goodvat Mcp Server
GoodVat MCP Server
A Model Context Protocol (MCP) server that gives AI assistants and agents access to global tax compliance knowledge and tools — built and maintained by GoodVat.
If you're selling anything, anywhere, this server answers the tax questions that come up: VAT rates and rules across the EU and UK, US state sales tax, India GST, registration thresholds, invoicing requirements, and more — plus live lookup tools to verify tax IDs.
What it does
- Tax guides & Q&A — ask natural-language questions like "what's the VAT rate in France for digital goods?" or "do I need to register for sales tax in California?" and get accurate, sourced answers covering:
- UK VAT
- EU VAT (all member states)
- US Sales Tax (state-by-state)
- India GST
- more jurisdictions added regularly
- VAT number lookup (EU) — validates EU VAT numbers in real time via the official VIES registry.
- UK VAT number lookup (HMRC) — coming soon.
Usage
GoodVat's MCP server is hosted remotely over streamable HTTP at:
https://api.goodvat.com/mcp
Option 1: Connect directly (remote HTTP)
If your MCP client supports remote/HTTP servers natively (e.g. Claude.ai, Claude Desktop's remote connectors, Cursor), point it straight at the URL above — no install needed.
{
"mcpServers": {
"goodvat": {
"url": "https://api.goodvat.com/mcp"
}
}
}
Option 2: stdio bridge (this package)
Some clients only support local stdio-based MCP servers. This package (@goodvat/mcp-server) is a thin stdio-to-HTTP bridge: it speaks stdio to your client and forwards each message to the remote endpoint above.
npx @goodvat/mcp-server
Add to your client's MCP server config:
{
"mcpServers": {
"goodvat": {
"command": "npx",
"args": ["@goodvat/mcp-server"]
}
}
}
Requirements
- Node.js >= 18
