I think so, but if you wanted to be pedantic you could make the argument that the same resource is not being served with the different Accept header. A welcome page is not the same thing as the JSON returned from the MCP spec.

A redirect actually does make sense but then there will be some percentage of users that end up copying the redirect URL and try to use that as the MCP URL
