So MCP has its own name cos its its own thing. Yes it is just search but it has a specific format that is a standard. Yes metric bolts are just different sized imperial bolts but they have a different name because they are a standard unto themselves.

RAG stands for retrieval augmented generation. Which is what u call it when dynamically searched text if fed into the prompt. So an LLM with an mcp is a rag but not all rags use mcp.

Their is both technically and functionally differences between ai agents and an ai u just talk to. Functionally an ai agent is multiple orders of magnitude more capable. Technically an ai agent is doing multiple round trips between generation and data retrieval/actions. Talking to a model is text in -> ai gen -> text out. An agent is text in -> ai gen -> data retrieval/ action -> return to ai gen as much as needed to complete task -> final answer ai gen -> text out.

I understand peoples disliking ai but that doesn’t mean that its all bullshit and that it doesn’t have lots of cool tech and isn’t useful.
