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 |
|---|---|---|---|---|
| Consumer Lending Licensing (UK, US, Canada credit licence registers) | regulated | 38.3 (thin) | - | - |
| EU/EEA Payment and E-Money Institutions (PSD2 passports) | regulated | 38.3 (thin) | - | - |
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.
