Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 47.5 | 17.5 | +30 | 32 |
| Discoverability | 73.9 | 60.4 | +13.5 | 32 |
| Developer Ergonomics | 31.4 | 17.9 | +13.5 | 32 |
| Operational Transparency | 23.3 | 11.3 | +12 | 32 |
| Access Clarity | 31.4 | 22.3 | +9.1 | 32 |
| Contract Governance | 9.2 | 6.4 | +2.8 | 32 |
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.

APIs.io cohort API. Briefs are published for rosters of
5 or more scored providers; below that a distribution is not meaningful.
