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 |
|---|---|---|---|---|
| Typed Decision Models | covered | 37.8 | - | 2 |
| Retrieval, Vector and RAG | covered | 37.8 | - | 2 |
| IDE Extension Marketplaces (JetBrains, VS Code, Open VSX, Docker Verified Publishers, PyPI orgs) | covered | 37.8 | - | 2 |
| Raycast Store Extensions (first-party publishers + community-wrapped products) | covered | 37.8 | - | 2 |
| Obsidian Community Plugins (third-party APIs the Obsidian plugin ecosystem integrates) | covered | 37.8 | - | 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.
