GitHub Copilot CLI (Public Preview)

The power of GitHub Copilot, now in your terminal.

GitHub Copilot CLI brings AI-powered coding assistance directly to your command line, enabling you to build, debug, and understand code through natural language conversations. Powered by the same agentic harness as GitHub's Copilot coding agent, it provides intelligent assistance while staying deeply integrated with your GitHub workflow.

See our official documentation for more information.

🚀 Introduction and Overview

We're bringing the power of GitHub Copilot coding agent directly to your terminal. With GitHub Copilot CLI, you can work locally and synchronously with an AI agent that understands your code and GitHub context.

• Terminal-native development: Work with Copilot coding agent directly in your command line — no context switching required.
• GitHub integration out of the box: Access your repositories, issues, and pull requests using natural language, all authenticated with your existing GitHub account.
• Agentic capabilities: Build, edit, debug, and refactor code with an AI collaborator that can plan and execute complex tasks.
• MCP-powered extensibility: Take advantage of the fact that the coding agent ships with GitHub's MCP server by default and supports custom MCP servers to extend capabilities.
• Full control: Preview every action before execution — nothing happens without your explicit approval.

We're still early in our journey, but with your feedback, we're rapidly iterating to make the GitHub Copilot CLI the best possible companion in your terminal.

Installation

Install globally with npm:

Launching the CLI

copilot

On first launch, you'll be greeted with our adorable animated banner! If you'd like to see this banner again, launch copilot with the --banner flag.

If you're not currently logged in to GitHub, you'll be prompted to use the /login slash command. Enter this command and follow the on-screen instructions to authenticate.

Using the CLI

Launch copilot in a folder that contains code you want to work with.

By default, copilot utilizes Claude Sonnet 4. We also support GPT-5 via an environment variable. Run COPILOT_MODEL=gpt-5 copilot to launch in GPT-5 mode. Or on Windows, run set COPILOT_MODEL=gpt-5 before running copilot.

Each time you submit a prompt to GitHub Copilot CLI, your monthly quota of premium requests is reduced by one. For information about premium requests, see About premium requests
