These companies publish an API, specification or operation carrying “Listings” but do not classify their business under it. Listed unranked and kept out of the count above, because one tagged operation is not a statement about what a company does.

Facet averages, against the whole catalog

Facet	This cohort	Catalog	Difference	Scored
Contract Quality	24.8	18.6	+6.2	36
Access Clarity	35.7	30	+5.7	36
Discoverability	63.1	59.1	+4	36

A facet is averaged over the members that carry it, not over the whole cohort — the “Scored” column is that count. Averaging an absent facet as zero would score our own coverage gaps as the providers’ posture.

mcp_pct counts any mcp/ artifact including ones API Evangelist derived from the provider OpenAPI; mcp_first_party_pct counts only servers the provider publishes. Prefer the latter.
