What it does

xmlvalid is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.

From the publisher's description, Electra Index matched it to one capability: invoicing. That makes it a candidate for tasks such as send and chase invoices.

Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

5 tools offered to AI assistants

  • validate_xml · Validate an XML document with xmlvalid: well-formedness, an XSD, DTD or RelaxNG schema, and for e-invoices the Schematron business rules of EN 16931, Peppol BIS, XRechnung, Factur-X and national formats. Pass the document as `xml` (its text
  • get_validation · The status and result of a validation started with validate_xml that was still running when it returned (status "queued" or "running"). Results are kept for 24 hours.
  • search_schemas · Search xmlvalid's catalog of official XML schemas (UBL, CII, Peppol, XRechnung, Factur-X, ISO 20022, HL7, sitemaps…) by name, namespace, root element or area. Returns each schema's slug to pass to validate_xml, its version and the business
  • explain_error · Explain an XML parsing or schema validation error message: what it means, why it happens and how to fix it, with an example. Understands libxml2 (xmllint, PHP, Python lxml, xmlvalid), Java (Xerces cvc-* codes, SAXParseException) and .NET (S
  • explain_rule · Explain an e-invoicing business rule by its id, such as BR-CO-15, BR-DE-1, PEPPOL-EN16931-R001 or a national CIUS rule: its message, level, the rule sets it belongs to, why invoices fail it and how to fix them. No API key needed.

What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
