Let me break down how AI agents actually work, because most explanations make it sound more complex than it is.
You talk to an LLM. The agent (your code) tells the LLM about available functions in the system prompt. The LLM responds with text. If that text matches the pattern you defined (like a function call format), your agent code catches it and runs the actual function. The agent then gives the result back to the LLM, which continues the conversation.
That's it. The LLM never directly executed anything. It just produced text your code interpreted.
This is why MCP exists. It standardizes the format so you don't have to reinvent the pattern every time. But the underlying concept? Exactly the same.
AI agents are powerful, sure. Just know what's doing the actual work.
