Attestwire provides an online service to validate European e‑invoices such as XRechnung and Peppol. Users can paste invoice XML to see which rule failed, get plain‑language explanations, and understand required fixes. The platform also offers a Model Context Protocol (MCP) that lets AI assistants call fourteen compliance tools without an API key, with optional paid plans for higher limits. Documentation, guides, and a rule reference are available publicly.
