Over the last week it answered 99.4% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

Available tools 8

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

render

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.

detect

detect_invoice

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

fix

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 not in the file (Leitweg-ID, seller contact, endpoint ids, payment terms) is taken from "values"; missing ones are listed in needs_input. Returns the change list, the remaining errors and the corrected XML. Counts as 2 requests.

parse

parse_invoice

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

supported

list_supported_formats

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

usage

my_usage

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

validate

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). Returns valid/invalid with every failed rule: id, severity, message, XPath.

E-Invoice Checker — questions

Answers built from our own checks of this server.

What can E-Invoice Checker do?

It exposes 8 tools, read directly from the server on our last check. Among them: detect_invoice, fix_invoice, list_supported_formats, my_usage, parse_invoice, render_invoice_html and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

Is E-Invoice Checker working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 92 of 92 checks got a reply (100.0%), average response time 978 ms. The bar chart above shows every period we have measured.

How do I connect E-Invoice Checker?

Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does E-Invoice Checker need an API key?

No. E-Invoice Checker completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is E-Invoice Checker?

It answers our handshake in 978 ms on average, which is faster than 8% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is E-Invoice Checker open source?

Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
