|---|---|---|---|---|
| Operational Transparency | 25.2 | 13.7 | +11.5 | 49 |
| Contract Quality | 22.7 | 17.6 | +5.1 | 49 |

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.
