Facet averages, against the whole catalog
| Facet | This cohort | Catalog | Difference | Scored |
|---|---|---|---|---|
| Contract Quality | 43.3 | 19.8 | +23.5 | 191 |
| Developer Ergonomics | 42.8 | 23.4 | +19.4 | 191 |
| Operational Transparency | 28.6 | 13.9 | +14.7 | 191 |
| Access Clarity | 37.5 | 26.5 | +11 | 191 |
| Discoverability | 70 | 61.2 | +8.8 | 191 |
| Contract Governance | 10.5 | 6.4 | +4.1 | 191 |
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) | 15% | 10% | +5 |
| MCP server (first-party) | 23% | 13% | +10 |
| Agent Skills | 0% | 0% | 0 |
| OAuth scopes | 10% | 11% | -1 |
| Security | 99% | 96% | +3 |
| Arazzo workflows | 3% | 2% | +1 |
| Governance rules | 38% | 14% | +24 |
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.
