Thanks for the feature request, @Livvux!

This is a duplicate of #9350, which is our primary tracking issue for MCP Tool Search / Lazy Loading. That issue has a comprehensive spec and is already assigned for implementation.

You can follow progress there and add any additional thoughts to the discussion.

Closing this as a duplicate - feel free to subscribe to #9350 for updates!
