GitHub has launched a technical preview of the GitHub Copilot SDK, a tool kit for embedding the “agentic core” of the GitHub Copilot CLI into applications.
Available on GitHub, the SDK was unveiled on January 22. Initially available for Node.js/TypeScript, Python, Go, and .NET, the GitHub Copilot SDK exposes the same engine behind the GitHub Copilot CLI, a production-tested agent runtime that can be invoked programmatically. There is no need to build orchestration, according GitHub. Users define agent behavior, and Copilot handles planning, tool invocation, file edits, and more, according to GitHub. A GitHub Copilot subscription is required to use the SDK.
Developers using the SDK can take advantage of GitHub Copilot CLI’s support for multiple AI models, custom tool definitions, Model Context Protocol (MCP) server integration, GitHub authentication, and real-time streaming. GitHub teams already have used the SDK for applications such YouTube chapter generators, custom GUIs for agents, speech-to-command workflows to run apps, games in which players can compete with AI, and ummarizing tools.
