Facet averages, against the whole catalog

|---|---|---|---|---|
| Contract Quality | 30.3 | 18.6 | +11.7 | 35 |
| Developer Ergonomics | 36 | 24.5 | +11.5 | 35 |

| Contract Governance | 13.5 | 9.7 | +3.8 | 35 |
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.

All 36 members of this roster resolve to a provider in the
catalog; 35 carry a score (97%).
The figures above describe the scored members only.
Coverage caveat. 26 of 35 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 14 November 2026, across 41591 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.
