  Yello is a Chicago-based talent acquisition software company, founded in 2008 (originally Recsolu),
  whose enterprise platform runs campus and early-career recruiting for roughly 100 Fortune 500
  employers across 70+ countries and 15+ languages. The product line covers campus planning,
  recruitment events, candidate sourcing, interview scheduling, a recruitment CRM, recruitment
  analytics and an AI campus recruiting agent, plus Yello Government Recruiting Solutions (YGRS) for
  public-sector hiring and the WayUp candidate marketplace and Symba new-hire readiness products
  acquired by the company. Yello Enterprise is delivered as per-customer tenant sites on yello.co and
  recsolu.com in US (us-east-1) and EU (eu-west-1) environments. Its integration surface with ATS and
  HRIS systems (Workday, Taleo, Oracle Recruiting Cloud, iCIMS, SAP SuccessFactors, Greenhouse, ADP)
  is real but is sold and provisioned through a partner/sales conversation rather than a public
  developer portal. The one openly reachable machine surface found is a remote Model Context Protocol
  server on the WayUp property, published with RFC 8414 / RFC 9728 OAuth discovery.

- name: WayUp MCP Server
  description: >-
    A remote Model Context Protocol (streamable HTTP) server operated by WayUp, a Yello company, at
    https://www.wayup.com/mcp. Discovered by probe: the host publishes RFC 9728 protected-resource
    metadata naming the endpoint and RFC 8414 authorization-server metadata for it. The server is
    fully OAuth-gated - an unauthenticated tools/list returns HTTP 401 with a WWW-Authenticate Bearer
    challenge carrying resource_metadata - so the tool set and input schemas require authenticated
    introspection. No public documentation of this server was found.
