Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 48.8 | 23.2 | +25.6 | 60 |
| Access Clarity | 51.6 | 26.5 | +25.1 | 60 |

| Contract Governance | 11.6 | 6.3 | +5.3 | 60 |
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.

All 64 members of this roster resolve to a provider in the
catalog; 60 carry a score (94%).
The figures above describe the scored members only.
Coverage caveat. 48 of 60 scored members had under half their catalog-attributable points satisfied at all (catalog_earned / catalog_max < 0.5). They are INCLUDED in the mean above. A large share here means the cohort mean is partly a measurement of how far our enrichment reached, not only of how these providers publish.Generated from the catalog build of 5 October 2026, across 29093 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.
