Facet averages, against the whole catalog
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.
What this cohort publishes
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.
This roster declares 764 members; 759
resolve to a provider in the catalog and 759 carry a score
(100%). The figures above describe the scored members only.Generated from the catalog build of
25 August 2026, across 26891
providers, using the same computation served by the
APIs.io cohort API. Briefs are published for rosters of
5 or more scored providers; below that a distribution is not meaningful.
