After learning how RAG gives AI better context, the next question is how AI connects to the world around it.
MCP, or Model Context Protocol, helps applications reach tools and data in a structured way, while governance defines what they can actually do.

RAG, or Retrieval-Augmented Generation, helped many people understand that AI needs more than a model.
It needs relevant knowledge from approved sources, so the answer is grounded in the right context instead of relying only on what the model already knows.
MCP moves the conversation one step further.
If RAG helps AI bring knowledge into the answer, Model Context Protocol helps AI applications connect with external capabilities in a more consistent way.
That connection matters because useful AI work rarely stops at generating text.
An application may need to search records, check information, update a ticket, or support an operational task. MCP gives this kind of interaction a clearer structure.
Governance is what keeps these connections safe.
Governance is what keeps these connections safe.
Permissions and usage limits define what an AI application can read or activate, so connection does not turn into uncontrolled access.
In the end, RAG gives AI better context, while MCP gives AI a more structured way to act.
The value comes when both are designed with clear boundaries from the start.
