name: Traced UCP Commerce MCP Server
provider: LinusBio (Linus Biotechnology Inc.)
summary: >-
  LinusBio's Traced consumer storefront at traced.life exposes a live, anonymous MCP endpoint
  implementing the Universal Commerce Protocol (UCP). A POST of tools/list returns HTTP 200 with
  13 tools and full JSON Schema 2020-12 input schemas. This is the ONLY machine-callable surface
  LinusBio publishes anywhere — the corporate site, ClearStrand-ASD site and every api./docs./
  developer. subdomain return the marketing site via wildcard DNS.

ownership:
  note: >-
    traced.life is named as the ordering site for the Traced test in LinusBio's own
    2026-07-07 press release ("To order Traced and for more information, please visit
    www.traced.life"), and the storefront footer links to LinusBio's LinkedIn company page.
    The store entity of record in the Shopify copyright notice is "Traced Ltd.".

platform_note: >-
  This server is provided by the Shopify platform, not authored by LinusBio. Every Shopify
  storefront on UCP 2026-04-08 serves the same 13-tool surface. It is recorded here because it
  is genuinely served from a LinusBio-controlled domain and is genuinely callable by an agent
  today. It exposes commerce only — no exposomics, laboratory, specimen or test-result data.

    note: >-
      A separate, authenticated Shopify Customer Account MCP surface exists behind OAuth
      (scope customer-account-mcp-api:full). It was NOT probed — it requires customer
      credentials — so no tool list is recorded for it.
