Vanilla LLMs have limited capabilities out of the box. You’re most probably familiar with RAG and MCP but how do they actually work and how to add these mechanisms (and more) to YOUR AI-powered application?

This post is a no-bs look into the implementation details and system architecture. The goal is to help senior engineers to move over their existing skills to agentic workflows. Even if you don’t do that or aren’t planning it, it’s probably a good idea to see that these acronyms just encapsulate simple ideas! There’s no rocket science here, as you can see in the diagrams.

Hope you enjoy this one.
