GetPackage could be useful to get the manifest information or package details and metadata such that it could be used in authoring a manifest

It might be valuable to explore whether WinGet could extend its configuration and package management capabilities to MCP tools.
For example, allowing a configuration file in the user folder to define MCP tools, and enabling search/install/configure from a registry (such as GitHub MCP Registry) via CLI. Additionally, providing a wrapper mechanism for developers to register their app’s built-in MCP tools systemwide could encourage interoperability, so that different apps on Windows can discover and cooperate with these tools in a unified way.
If a similar proposal has already been discussed or announced, I apologize for the duplication, Thanks a lot
