Facet averages, against the whole catalog

|---|---|---|---|---|
| Developer Ergonomics | 48.4 | 23.4 | +25 | 37 |
| Operational Transparency | 37.3 | 14 | +23.3 | 37 |

| Contract Governance | 9.8 | 6.4 | +3.4 | 37 |
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.

15 September 2026, across 27661
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.
