You can set up an MCP server in front of the LLM so that it can reach out to external APIs, like news sites/feeds/etc..
But, the majority of its behavior is going to be from its original training set, which is likely 12+ months old at this point. The pipeline for this is so long to generate and refine a good new AI model, that your data sets are constantly out of date.
An MCP server will only get you so far.
