What it does
Validate a hosted astronomy VOTable against astropy's ~80-code IVOA conformance corpus with exact line-and-code evidence — real conformance validation, not an XSD or well-formedness parse
Validate one public IVOA VOTable file against astropy's IVOA conformance corpus (invalid UCDs, bad unit strings, astroYear, datatype/arraysize/value semantics) using astropy io.votable.validate with exact line, code, message, and severity evidence, or compare two same-version-family VOTables across catalogs, hosts, or versions, with a clear format-and-conformance-versus-scientific-correctness boundary.

VOTable Check questions
Scope and boundaries for VOTable Check.
01What does VOTable Check actually check?
Validate one public IVOA VOTable file against astropy's IVOA conformance corpus (invalid UCDs, bad unit strings, astroYear, datatype/arraysize/value semantics) using astropy io.votable.validate with exact line, code, message, and severity evidence, or compare two same-version-family VOTables across catalogs, hosts, or versions, with a clear format-and-conformance-versus-scientific-correctness boundary.
02What does it never do?
It reports what its pinned engine measured and nothing more — it does not judge quality, correctness of your underlying business decisions, or anything outside its stated scope, and it never fabricates a result.
03What does it cost?
Nothing. Every published app is free to use with fair-use rate limits.
04Can my assistant connect directly?
Yes — any MCP-compatible assistant can connect straight to the canonical endpoint: https://powmcp.com/votable-check/mcp. Marketplace listings are conveniences over the same live engine.
