PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs in the cloud
  • Transport: Streamable HTTP
  • Category: Accounting, finance & tax
  • You need to fill in: Authorization

Install

Pick the AI app you use, then copy the settings.

Before you install

Values marked secret are keys to your account. Never share them or paste them into a chat.

You need

Which app do you use?

Pick your app above. We remember it, so next time the button says “Install in …”.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Run this in your terminal

claude mcp add --transport http einvoice https://einvoicechecker.com/v1/mcp --header 'Authorization: your-value'

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "einvoice": {
      "url": "https://einvoicechecker.com/v1/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "einvoice": {
      "type": "http",
      "url": "https://einvoicechecker.com/v1/mcp",
      "headers": {
        "Authorization": "your-value"
      }
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This address needs a key in a request header, which the add-connector menu cannot set. Use Claude Code, Cursor or VS Code instead.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

  • Authorization secret HTTP header
    Bearer . Optional: free key at https://einvoicechecker.com/developers/; without it the anonymous rate limit applies.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Tool names and descriptions exactly as the server reported them on Nov 8, 2026. The maker wrote them, not us; we show them as plain text.

  • list_supported_formats

    Which formats, profiles and rule sets this service supports, and what each tool costs.

  • detect_invoice

    Identify the format, syntax, profile/customization and country standard of an e-invoice file. Cheap first step before validating.

  • parse_invoice

    Extract the invoice as normalised JSON: number, dates, seller, buyer, lines, VAT breakdown, totals, payment details. Works for every supported format.

  • fix_invoice

    Fix validation errors of an EN 16931 invoice (XRechnung, Peppol BIS, ZUGFeRD/Factur-X XML, UBL, CII) deterministically: empty elements, decimals, date and code formats, specification ids; with totals=true also recalculates totals and the VAT breakdown from the lines. Data that is

  • validate_invoice

    Run the official rule set for the detected format (KoSIT for XRechnung/ZUGFeRD/Factur-X, OpenPeppol for Peppol BIS, FA(3) schema for KSeF, Porezna uprava HR-CIUS schematron for Croatian eRačun, Facturae XSD + calculation/NIF/DIR3 rules for Spain, LHDN SDK rules for MyInvois). Ret

  • render_invoice_html

    Human-readable invoice document (HTML, A4 print layout) from the XML, in the requested language.

  • render_invoice_pdf

    Human-readable PDF of the invoice (counts as 2 requests). Returned as a base64 resource.

  • my_usage

    Plan, monthly quota, usage this month and subscription state of the API key used for this connection. Free.

Common questions

Is E-Invoice Checker safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

You need to fill in: Authorization

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.2) reached the registry 25 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?
