Kin Score
Markets this provider is in provisional
The Kin Score Market layer reads a provider inside its market: its position, and how deep its integrations go. Depth is only comparable within a position. Provisional and unweighted: not part of the Kin Score or agent readiness.
| Market | Position | Depth | Registered MCP server | Declares compatibility |
|---|---|---|---|---|
| Databases (PostgreSQL wire) | builds-on | 51.7 | - | 2 |
| Agent Skills (SKILL.md packages) | builds-on | 51.7 | - | 2 |
| Infrastructure-as-Code Provider Registries (Terraform, OpenTofu, Pulumi) | builds-on | 51.7 | - | 2 |
Registered MCP server and declares compatibility are report only — not weighted. Undeclared means we found nothing we can read, so there is no number: we never infer integrations.
Standards implemented 2
Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.
