hernaninverso/eleata-einvoice-mcp

Validate **EU electronic invoices** and explain validation **error codes** directly from your AI
coding agent (Claude, Cursor, Copilot, …). It wraps the hosted eleata validation
API plus a bundled offline error-code reference.
> Never ship a broken invoice. When you ask your agent "is this FatturaPA / XRechnung / Peppol file
> valid?", it runs the official Schematron rules and gets back the rule id **and the fix** — before a
> rejection (an SdI *scarto*, a Chorus Pro refusal, a KSeF error) ever happens.
