Let an AI assistant read and check European electronic invoices.
Point Claude (or any MCP-compatible client) at a .pdf or .xml invoice and it
answers with the contents in plain language, plus a consistency check against
the European standard **EN 16931**.
Supports **Factur-X**, **ZUGFeRD**, **XRechnung**, **UBL** and **CII**.
Why this exists
A Factur-X invoice is a PDF with structured data hidden inside it. The page a
human reads and the data a machine imports are two different things, and they do
not always agree. This server exposes both, so an assistant can answer "what is
actually in this file?" rather than reading the visible page and hoping.
France made structured e-invoicing mandatory for receiving on 1 September 2026,
so these files are now arriving in ordinary inboxes.
Install
No dependencies. Python 3.10 or newer is all you need.
1. Download facturolia_mcp.py.
2. Get a free API key at facturolia.fr/en/pricing.
3. Add it to your client configuration. For Claude Desktop, that is
claude_desktop_config.json:
Restart the client. Two tools appear.
Tools
| Tool | What it returns |
|---|---|
| read_invoice | Full contents: parties, dates, lines, VAT breakdown, totals, IBAN, plus the EN 16931 check |
| check_invoice | The compliance verdict and anomalies only, for "is this invoice correct?" |
Both take one argument, path, an absolute path to a .pdf or .xml file.
Configuration
| Variable | Default | Meaning |
|---|---|---|
| FACTUROLIA_API_KEY | required | Your key |
| FACTUROLIA_LANG | en | Response language, en or fr |
| FACTUROLIA_BASE_URL | https://facturolia.fr | Override for testing. Must be https:// (plain http:// only for localhost), otherwise the key is not sent |
With FACTUROLIA_LANG=fr the answers come back in French, with French date and
label conventions. The tool descriptions stay in English so that every client
understands them.
What it does with your file
The file is **sent to the Facturolia API** to be analysed. It is processed in
memory and discarded immediately, no invoice is stored, and the contents do not
appear in the technical logs. The servers are in the European Union.
That said, this is **not local processing**. If your policy forbids sending
invoices to an external service, use the API yourself inside your own network
instead, or do not use this server.
