GitHub Copilot CLI is GitHub Copilot’s command-line interface that brings the agentic coding assistant directly into the terminal. It replaced the earlier Copilot extension for GitHub CLI. The tool lets you converse with Copilot, generate and explain shell commands, carry out coding tasks agentically, and use external tools via the Model Context Protocol (MCP). Copilot CLI runs locally in the developer’s environment, enabling code edits, command execution and repository work from the console.
