summary: www.xwing.com serves a live, unauthenticated Model Context Protocol endpoint at /_api/mcp. It
  is REAL and it answers — initialize and tools/list both returned HTTP 200 anonymously on 2026-09-04
  — but it is PLATFORM-AUTHORED, not an Xwing engineering product. The site runs on Wix, and Wix serves
  this "Site Visitor Assistant" endpoint (and the matching llms.txt) for every site on the platform. The
  nine tools are Wix platform tools for reading site content and calling the Wix REST API on a visitor's
  behalf; none of them exposes Xwing's own autonomy technology, flight data, or any Xwing-built API. Recorded
  because it is genuinely reachable by an agent, and labeled so no reader mistakes it for a first-party
  developer surface.
authorship: platform
authorship_note: serverInfo.name is 'Site Visitor Assistant for site "Xwing" (https://www.xwing.com/_api/mcp)'.
  The tool set is identical Wix boilerplate across Wix-hosted sites; Xwing did not author or configure
  it.

  note: No authorization challenge is returned. /.well-known/oauth-authorization-server and /.well-known/oauth-protected-resource
    both return HTTP 400 on this host (see well-known/xwing-well-known.yml), so there is no discovery
    document behind it. Visitor-scoped Wix API calls use a token minted by the GenerateVisitorToken tool.

crosswalk: none
crosswalk_reason: No tool crosswalk is emitted. A crosswalk binds MCP tools to backing OpenAPI operationIds,
  and Xwing publishes no OpenAPI (see x-coverage in apis.yml). The tools here back onto the Wix platform
  REST API, which belongs to Wix, not to Xwing.
