Questions

Which websites load from spec.modelcontextprotocol.io?
The 4 sites listed on this page. A site is listed when its stored HTML has a script, iframe or stylesheet from the host, or one of its own scripts names the host in an absolute URL.
Is spec.modelcontextprotocol.io a third party for every site listed?
Yes: a host under a site's own registrable domain is never recorded for that site, so every site here loads from spec.modelcontextprotocol.io as a dependency outside its own domain.
