Copilot Remote Bridge

Securely bridge Microsoft Teams or Slack to your local GitHub Copilot CLI. Chat with your workspace from your phone, tablet, or any device.

Why?

GitHub Copilot CLI's agent mode is powerful but requires a terminal. This extension lets you interact with it from any Teams or Slack client — including mobile — while the agent runs locally in your VS Code workspace.
