Agentic RAG: Basic RAG Plus MCP Tool Calls

That second question isn’t a retrieval problem — it’s a computation problem that depends on live, structured, user-specific data. This is exactly the gap agentic RAG closes: it keeps the semantic search RAG is good at, and bolts on tool calls (via MCP) so the agent can reach into live systems, fetch real numbers, and reason over them before answering. A simple way to think about it:
