Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Operational Transparency | 24 | 11.3 | +12.7 | 51 |
| Contract Quality | 26.6 | 17.5 | +9.1 | 51 |
| Developer Ergonomics | 26.8 | 17.9 | +8.9 | 51 |

| Contract Governance | 7.1 | 6.4 | +0.7 | 51 |
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.
