What Are the Components and Interaction Flow of MCP in AI Agents? A Complete Guide

The article explains MCP (Model Context Protocol) as a standardized interface for AI agents, detailing its architecture (Host, Client, Server), three core types (Tools, Resources, Prompts), transport options (Stdio and Streamable HTTP), security best practices, and how it differs from function calling.

RAG Chunking Strategies and How to Balance Chunk Size (Full Answer)

The article outlines four common RAG chunking methods—fixed-length, recursive, semantic, and structure-based—explains their pros and cons, discusses the trade‑off between chunk size, retrieval precision and context completeness, and introduces two advanced techniques, Contextual Retrieval and Late Chunking, with empirical results from Anthropic and Jina AI.

Agentic RAG vs Regular RAG: Key Differences, Trade‑offs, and Interview‑Ready Answer

This article explains what Agentic RAG is, contrasts it with ordinary RAG by detailing its dynamic decision‑making, multi‑step retrieval loop, higher cost and latency, and suitable scenarios, and outlines two implementation patterns—single‑agent and multi‑agent—plus a concise interview response.

RAG vs Fine‑Tuning vs Long Context: Choosing the Right Technique for AI Agents

The article explains why Retrieval‑Augmented Generation (RAG) addresses the static knowledge limitation of large models, contrasts its role of “what to say” with fine‑tuning’s focus on “how to say,” compares costs and performance against long‑context models, and offers a practical hierarchy (Prompt → RAG → LoRA/QLoRA fine‑tuning → Distillation) plus best‑practice combinations.
