3D Asset Check questions
Scope and boundaries for 3D Asset Check.
01What does 3D Asset Check actually check?
Run official glTF conformance checks and measure geometry, textures, materials, animations, extensions, transfer weight, and likely runtime pressure from a public asset URL.
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/gltf-asset-preflight/mcp. Marketplace listings are conveniences over the same live engine.
