MCP waxaa laga yaabaa 2 faahfaahfaahfaahfaahfaahfaahfaaha RAG:

• Data processed by a RAG is tailored for a model. If one wants to use a new model, one must re-execute the parsing phase. MCP standardizes the interactions between a client and a server, making them technology-independent.

  
  

• RAG allows the reading of data. MCP allows any API call to either access data dynamically or execute actions!

The text appears to be a blog post or a personal website, and it mentions some of your projects and experiences with GitHub, but it does not provide any metrics or statistics on the popularity of your repositories.

If you want to know more about the popularity of your GitHub repositories, I would recommend checking out GitHub's own analytics tools, such as GitHub Insights or the Repository Insights API.
