Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

MCP server for European invoicing rules — VAT rates, e-invoicing requirements, format standards, and compliance validation for EU-27 + EEA countries

Readme

euinvoice-mcp

An MCP server for European invoicing rules. Query VAT rates, e-invoicing requirements, format specifications, and compliance rules for EU-27 + EEA countries — directly from your AI assistant.

Why

European invoicing is fragmented. Every country has different VAT rates, e-invoicing mandates, accepted formats, and compliance rules. This MCP server puts all of that knowledge at your fingertips.

What's included

10 tools covering the full EU invoicing landscape:

| Tool | Description | |------|-------------| | get_vat_rates | VAT rates for any country (standard, reduced, super-reduced, parking) | | list_vat_rates | Compare standard VAT rates across all countries | | get_einvoicing_requirements | E-invoicing mandates, systems, and formats per country | | get_invoice_format | Format specs (UBL, CII, Factur-X, XRechnung, FatturaPA, Peppol BIS) | | validate_invoice_fields | Required fields per country and transaction type (B2B/B2G/B2C) | | get_reverse_charge_rules | When and how to apply reverse charge | | get_oss_rules | One-Stop Shop rules for cross-border B2C sales | | get_b2b_mandate_status | B2B e-invoicing mandate timeline across all countries | | get_en16931_info | EN 16931 standard details and CIUS extensions | | compare_countries | Side-by-side comparison of two countries |

4 resources for direct data access:

  • euinvoice://data/vat-rates — Complete VAT rates database
  • euinvoice://data/einvoicing-requirements — E-invoicing requirements per country
  • euinvoice://data/invoice-formats — Format specifications
