Cline is an open-source AI coding agent that lives in a developer's editor and terminal. It can read and write files, run terminal commands, use a browser, and help build features through natural conversation, with every action requiring explicit user approval. It supports Plan/Act modes, the Model Context Protocol (MCP) for extensibility, and works with multiple AI model providers including Claude, GPT, Gemini, and local models. It is available as a VS Code extension, JetBrains plugin, CLI tool, and SDK for building custom agents.
