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 |
|---|---|---|---|---|
| Agriculture and Food (Farm Data, Nutrition) | mixed | 38.9 | - | - |
| Health and Wellness (consumer health, fitness, wearables) | mixed | 38.9 | - | - |
| ONVIF Video Analytics (video surveillance, edge cameras, computer vision) | mixed | 38.9 | - | - |
| Obsidian Community Plugins (third-party APIs the Obsidian plugin ecosystem integrates) | mixed | 38.9 | - | - |
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.
