  Aro Biotherapeutics publishes no OpenAPI, no developer portal and no API key programme, so there
  is no securityScheme to derive from. The only callable surface on the domain is the Wix-provided
  Site MCP endpoint, and this profile records the auth model that endpoint actually enforces, as
  observed live.

  description: >-
    Discovery is unauthenticated. POST tools/list to https://www.arobiotx.com/_api/mcp with no
    credentials returns HTTP 200 and the full 9-tool manifest with input schemas.

- name: visitorToken
  type: session-token
  issued_by: GenerateVisitorToken
  passed_as: visitorToken parameter on the tool call (not an HTTP header)
  applies_to:
  - CallWixSiteAPI
  - ExecuteWixAPI
  description: >-
    Actions taken on a visitor's behalf require a visitor access token. An agent calls the
    GenerateVisitorToken tool, which takes no parameters and creates an anonymous visitor session,
    then passes the returned token as the visitorToken argument. This is a self-service anonymous
    session, not an identity credential — no registration, account or approval step exists.

    http_status: 200

observations:
- >-
  GET (rather than POST) on https://www.arobiotx.com/_api/mcp returns HTTP 401 application/json,
  confirming the endpoint enforces the MCP transport contract rather than answering everything 200.
- >-
  No OAuth metadata is published: /.well-known/oauth-authorization-server and
  /.well-known/oauth-protected-resource both return 400 on this origin.
- >-
  ExecuteWixAPI is annotated destructiveHint:true and executes caller-supplied JavaScript against
  the Wix REST API under the anonymous visitor session. Anyone on the internet can obtain that
  session, so the effective trust boundary is whatever the Wix visitor role permits on this site.
