Details
From the project READMEGoodVat 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

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
