Anatomy of an AI Agent: Understanding the 5 Key Components An AI Agent is more than just an LLM. It's a combination of intelligence, knowledge, tools, and execution. Here's how the main components work together: 1️⃣ LLM = The Brain Reads, writes, reasons, and makes decisions. 2️⃣ RAG = Brain + Library Retrieves relevant information from external knowledge sources before generating answers. 3️⃣ MCP = The Nervous System Connects AI models with external tools, applications, and data through a standardized protocol. 4️⃣ Skills = Muscle Memory Reusable instructions and workflows that help an agent perform tasks consistently. 5️⃣ AI Agent = Brain + Hands Combines reasoning, planning, and tools to execute tasks autonomously. The Big Picture: LLM provides intelligence. RAG provides knowledge. MCP provides connectivity. Skills provide reusable capabilities. AI Agents bring everything together to get work done.
