Structure File Check
What it does
Validate a hosted PDBx/mmCIF structure against the wwPDB DDL2 dictionary with gemmi, with exact category-and-item evidence — real dictionary validation, not a syntax parse
Validate one public PDBx/mmCIF macromolecular structure file against the bundled wwPDB PDBx/mmCIF DDL2 dictionary using gemmi validate with exact category, item, and severity evidence, or compare two same-lineage structures across hosts or versions, with a clear dictionary-conformance-versus-structural-correctness boundary.

Structure File Check questions
Scope and boundaries for Structure File Check.
01What does Structure File Check actually check?
Validate one public PDBx/mmCIF macromolecular structure file against the bundled wwPDB PDBx/mmCIF DDL2 dictionary using gemmi validate with exact category, item, and severity evidence, or compare two same-lineage structures across hosts or versions, with a clear dictionary-conformance-versus-structural-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/structure-file-check/mcp. Marketplace listings are conveniences over the same live engine.
