GitHub Copilot CLI

GitHub Copilot CLI is a command-line interface that brings AI-powered coding assistance directly to the terminal.

GitHub Copilot CLI brings AI-powered coding assistance directly to your command line. It enables you to build, debug, and understand code through natural language conversations. It integrates with your GitHub repositories, issues, and pull requests while authenticating with your existing GitHub account. The coding agent ships with GitHub's MCP server by default and supports custom MCP servers and Language Server Protocol servers. You can preview every action before execution and choose from models including Claude Sonnet 4.5, Claude Sonnet 4, and GPT-5.
