Gemini CLI

Gemini CLI is your open-source AI agent: it brings the power of Gemini models directly into your terminal.

The Gemini CLI is an open-source, terminal-first AI agent providing direct, lightweight access to the Gemini model capabilities. It operates as an interactive Read-Eval-Print Loop (REPL), enabling developers to execute complex tasks like code generation, project analysis, and bug fixing through natural language prompts. The CLI leverages a Reason and Act (ReAct) loop, orchestrating built-in tools (file system operations, shell commands, web search) and custom extensions via the Model Context Protocol (MCP). Users can access powerful models, including Gemini 2.5 Pro and Gemini 3 Pro, for high-performance agentic coding and streamlined workflows, all managed from the command line.
