Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Developer Ergonomics | 43.8 | 23.2 | +20.6 | 375 |
| Contract Quality | 32.1 | 17.6 | +14.5 | 375 |
| Access Clarity | 39.7 | 26.5 | +13.2 | 375 |
| Operational Transparency | 26.8 | 13.7 | +13.1 | 375 |
| Discoverability | 67.4 | 58.1 | +9.3 | 375 |
| Contract Governance | 13.7 | 6.3 | +7.4 | 375 |
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.
What this cohort publishes
| Artifact | This cohort | Catalog | Difference |
|---|---|---|---|
| MCP server (any) | 21% | 14% | +7 |
| MCP server (first-party) | 19% | 12% | +7 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 51% | 11% | +40 |
| Security | 99% | 98% | +1 |
| Arazzo workflows | 7% | 2% | +5 |
| Governance rules | 24% | 14% | +10 |
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.
