description: >-
  Keyo is a palm-based biometric identification platform offering a complete
  suite of touchless identity SaaS for payments, access control, ticketing, and
  time & attendance. Its palm-print and palm-vein (near-infrared) technology
  lets people verify their identity with a wave of the hand. Keyo exposes a REST
  API (developers.keyo.co) for managing biometric Identities and driving palm
  enrollment on Keyo devices, secured with the OAuth 2.0 client-credentials flow,
  plus real-time webhooks for enrollment and identification events. Keyo is
  backed by 500 Global and Obvious Ventures.

  note: 'Renamed from MCPServer 2026-09-03 (roadmap#247): the manifest self-describes as status: candidate — a tool list derived from the published API contracts, not an existing server. The scorer already read the manifest and reported mcp_server correctly; the MCPServer type was crediting the artifact-type surfaces with a server that does not exist.'
