What is AI Agent?
TL;DR
An AI system that autonomously sets goals, makes plans, uses tools, and executes tasks.
AI Agent: Definition & Explanation
An AI Agent is an AI system that can autonomously formulate plans, use tools and APIs, and complete tasks through multiple steps in pursuit of a user-defined goal. Unlike simple question-answering, AI agents can automatically perform web searches, execute code, manage files, and interact with external services. For example, Claude Code is a terminal-based AI coding agent that autonomously writes, edits, tests, and debugs code. The MCP (Model Context Protocol) is standardizing how agents connect with various tools and data sources.
