eleata e-invoice MCP server

This is a small helper that lets your AI check European electronic invoices for problems before you send them. If your AI can already chat but cannot read a Peppol, XRechnung, FatturaPA or Factur-X file, this adds that skill. It is handy for anyone who sends or receives e-invoices and is tired of rejections.

What this MCP server does

You paste an invoice file into the chat and ask your AI if it is valid. The AI sends it to this helper, which passes it to the eleata validation service. That service runs the official rule sets used across Europe and sends back a result: valid or not valid, plus each rule that failed, what it means, and how to fix it. You also get a plain-English explanation of any error code, even without an internet connection for that part.

What you can do with it

• Check a Peppol BIS, XRechnung, Factur-X/ZUGFeRD, UBL or CII invoice for errors
• See exactly which rule failed and what to change
• Look up what an error code like 00400 or BR-DE-21 means
• Ask which invoice formats can be validated today
• Catch problems before a rejection from SdI, Chorus Pro or KSeF

Try asking your AI

• “Validate this XRechnung file and tell me what to fix”
• “What does FatturaPA error 00400 mean and how do I fix it?”
• “Which e-invoice formats can you validate today?”
• “Is this Peppol invoice valid? Here is the XML”

What it gives back to you

You get a clear answer in the chat: valid or not valid. If something is wrong, you see each rule id, a short explanation and the suggested fix. For error-code questions you get a plain-English explanation, no file needed.
