description: 'Windfall (windfall.com, formerly windfalldata.com) is a people-intelligence and AI platform that personalizes
  go-to-market workflows with wealth and career data. Its developer-facing Windfall API delivers enriched household and career
  data on a single-record basis in real time: submit a person record with basic PII and receive that individual''s household
  net worth, a stable Windfall ID, and career signals such as a LinkedIn URL and title, returned as JSON in one sub-second
  request. Coverage is United States, data is refreshed weekly, and the API is used for real-time lead routing and grading,
  marketing enrichment, and analytics scoring. Authentication is a Windfall-issued header token with a dedicated sandbox environment
  of deterministic test personas. Windfall is SOC 2 Type 2 certified.'

  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.'
