# Vendor facets — Wix. A website builder that turns every site into an MCP server at
# /_api/mcp and auto-generates an llms.txt. Both are Wix's, not the site owner's: the MCP tool set
# is identical on every site (and calls wixapis.com), so it grades `platform`; the llms.txt is
# derived until the owner edits it. 0.22.0's release notes counted 62 Wix sites among the 292
# providers holding full mcp_server credit for other people's engineering.

summary: >-
  Every Wix site answers MCP at /_api/mcp and serves an auto-generated llms.txt, with no setup. The MCP
  server is the same seven-tool Wix template on every site, calling Wix's APIs, so it grades `platform`
  (0.25 of mcp_server); the generated llms.txt counts as derived (0.25). A site owner who edits the llms.txt
  makes it their own and earns full credit for that work. Wix's developer MCP manages Wix itself and earns
  a site nothing.

  description: >-
    Every Wix site serves an unauthenticated MCP server at <site>/_api/mcp with the same Wix-defined tools
    (SearchInSite, GetBusinessDetails, SearchSiteApiDocs, CallWixSiteAPI, GenerateVisitorToken, docs readers).

  description: >-
    Wix generates and maintains /llms.txt from public site content; editing it in the dashboard stops
    automatic updates, and it needs a custom domain and indexing enabled.

    One Wix template on every site, its CallWixSiteAPI tool pointing at wixapis.com. 0.22.0 grades it
    `platform` (0.25); 0.23.0 marks /_api/mcp platform-generated only on hosts fingerprinted as Wix (all/0-working/platform-hosts.json).

  note: >-
    We found no documented way for a Wix site to serve its own .well-known documents or a UCP/ACP profile;
    the only agent surfaces Wix documents are the two it generates.

  A model, not a score. Adopting this vendor changes a provider's Kin Score only when the provider publishes
  the resulting artifacts on its own surface; nothing here writes a score, and no sponsorship or partnership
  can.
