validate

validate_e_invoice

validate_xml

Check XML well-formedness. Returns bounded errors and warnings with locations; uses one validation from the daily allowance.

validate_xml_against_xsd

Check XML against a pinned officialSchema package or supplied XSD 1.0/1.1. Imports resolve inside the selected package only. Returns bounded findings and original schema hashes. The mf-etransport-v2 package also runs original official Schematron 2.0.2, all phases, with separate metadata.

XSDHub XML validation — questions

Answers built from our own checks of this server.

What can XSDHub XML validation do?

It exposes 8 tools, read directly from the server on our last check. Among them: explain_validation_error, get_xsdhub_capabilities, get_xsdhub_page, list_supported_standards, search_xsdhub_guides, validate_e_invoice and 2 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →

What is XSDHub XML validation mostly used for?

Its tools cluster around xsdhub and validate. That is what this server is built to work with — the grouping comes from the actual tool names, not from a category we assigned.

Is XSDHub XML validation working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 91 of 91 checks got a reply (100.0%), average response time 230 ms. The bar chart above shows every period we have measured.

How do I connect XSDHub XML validation?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does XSDHub XML validation need an API key?

No. XSDHub XML validation completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 8 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is XSDHub XML validation?

It answers our handshake in 230 ms on average, which is faster than 59% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
