Cognito

aid: cognito
name: Cognito
description: 'Cognito (cognitohq.com, operated by BlockScore, Inc.) is an identity verification, KYC, and AML compliance API
  provider that was backed by Y Combinator and Battery Ventures and acquired by Plaid in 2020. Its API turns a phone number,
  name, or ID document into a verified identity in under a minute, covering 209 countries and thousands of document types.
  Three developer products sit on one REST API: Identity (phone-first, frictionless verification), Flow (an all-in-one hosted
  / embeddable verification experience integrated in minutes with document and selfie checks), and Screening (watchlist, sanctions,
  and politically-exposed-person AML screening with daily re-scans across 20+ lists). The API is JSON:API (application/vnd.api+json),
  date-versioned via a Cognito-Version header, and authenticated with HTTP request signatures (HMAC-SHA256 over a digest of
  the body). It ships a sandbox host, signed webhooks, and client SDKs for seven languages.'

  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.'
