eleata e-invoice MCP server

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.
