  probe of https://www.deinde.com/api/ucp/mcp

api: DEINDE Commerce (UCP MCP)
docs: https://www.deinde.com/llms.txt

summary: >-
  The DEINDE UCP MCP endpoint is anonymously reachable for discovery, catalog, cart and
  checkout construction — an unauthenticated tools/list returned all 13 tools with full
  schemas. There is no API key, and no developer registration. What is gated is money and
  customer data: completing a checkout requires a buyer-approved payment instrument
  supplied through a UCP payment handler, and customer-account operations run through the
  Shopify-operated OAuth 2.0 / OpenID Connect authorization server the store advertises
  from its own host.

  note: >-
    No credential was presented on the probe. The only required request metadata is
    meta["ucp-agent"].profile — a URI naming the calling agent's UCP profile, which the
    server fetches and validates. It is agent identification, not authentication; a
    malformed or unfetchable profile returns JSON-RPC error -32001 profile_malformed.

- id: ucp-agent-profile
  type: agentIdentity
  location: request body
  parameter: meta.ucp-agent.profile
  required: true
  format: uri
  note: >-
    Required on every tool call. Server-side fetched and content-type checked; this is
    the mechanism by which the merchant identifies which agent is transacting.

    Operated by Shopify on Debut's behalf. Subject types are public; the resource server
    metadata at /.well-known/oauth-protected-resource names
    https://www.deinde.com as the resource and both https://account.deinde.com and the
    Shopify issuer as authorization servers, with bearer tokens in the Authorization
    header.

- id: buyer-payment-approval
  type: humanApproval
  applies_to:
  - complete_checkout
  note: >-
    The store's published agent instructions state that agents must not complete payment
    without contemporaneous buyer consent, and recommend routing payment through Shop Pay
    via the cross-store Shop skill when consent cannot be obtained in the moment. This is
    a policy control on top of the payment handlers declared in /.well-known/ucp
    (Google Pay among them), not a transport credential.

  note: >-
    debutbiotech.com is a Webflow marketing site with no login, no account system and no
    API. Nothing to authenticate against.
