Geospatial Catalog Check
What it does
Traverse and validate a hosted STAC catalog's whole link tree before you publish it
Recursively fetch and traverse a hosted STAC catalog, collection, or item link tree and validate every linked JSON document against the pinned STAC core and extension schemas for its detected version, with link and asset-href integrity findings located per document, or compare two same-lineage catalog roots — validating machine-checkable structure only, never the truth of the underlying geospatial data.

Geospatial Catalog Check questions
Scope and boundaries for Geospatial Catalog Check.
01What does Geospatial Catalog Check actually check?
Recursively fetch and traverse a hosted STAC catalog, collection, or item link tree and validate every linked JSON document against the pinned STAC core and extension schemas for its detected version, with link and asset-href integrity findings located per document, or compare two same-lineage catalog roots — validating machine-checkable structure only, never the truth of the underlying geospatial data.
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/geo-catalog-check/mcp. Marketplace listings are conveniences over the same live engine.
