 The MCP Registry uses namespace authentication to ensure that servers come from their claimed sources. Server names follow a reverse DNS format (like `io.github.username/server` or `com.example/server`) that ties them to verified GitHub accounts or domains.
 
-This namespace system ensures that only the legitimate owner of a GitHub account or domain can publish servers under that namespace, providing trust and accountability in the ecosystem. For details on authentication methods, see the [Authentication guide](./authentication.mdx).

 Server metadata is generally immutable, except for the `status` field which may be updated to, e.g., `"deprecated"` or `"deleted"`. We recommend that aggregators keep their copy of each server's `status` up to date.
 
-The `"deleted"` status typically indicates that a server has violated our permissive [moderation policy](./moderation-policy.mdx), suggesting the server might be spam, malware, or illegal. Aggregators may prefer to remove these servers from their index.
