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 |
|---|---|---|---|---|
| Workplace Collaboration App Marketplaces | builds-on | 29.6 | - | 1 |
| Zoom App Marketplace and Partner Ecosystem (builders and partners on Zoom) | builds-on | 29.6 | - | 1 |
| Artifact Hub Cloud-Native Packages | builds-on | 29.6 | - | 1 |
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
