A new tool is simplifying how developers build AI-powered agents, as GitHub introduces the GitHub Copilot SDK in technical preview.
The GitHub Copilot SDK allows developers to embed agentic AI capabilities directly into any application. Instead of building complex agent workflows from scratch, developers can now use the same core system that powers GitHub Copilot CLI. The SDK can plan tasks, invoke tools, edit files, and run commands as a programmable layer inside apps.
Building agent-based workflows typically requires managing context across multiple steps, orchestrating tools and commands, routing between models, integrating MCP servers, and handling permissions, safety limits, and failures. GitHub says the new SDK removes this heavy upfront work by providing a production-tested execution loop that developers can reuse.
With the SDK, teams no longer need to create their own planners or runtime systems. They can embed Copilot’s agentic loop directly and focus on their product logic, while GitHub handles authentication, model management, MCP servers, custom agents, chat sessions, and streaming.
The technical preview supports Node.js, Python, Go, and .NET. Developers can use an existing GitHub Copilot subscription or bring their own key. The github/copilot-sdk repository includes setup guides, starter examples, and SDK references for each supported language.
GitHub recommends starting with a single task, such as updating files, running commands, or generating structured outputs. Copilot then plans and executes the steps, while the application provides domain-specific tools and rules.
The SDK builds directly on the growing capabilities of Copilot CLI. The CLI already supports project planning, file editing, command execution, custom agents, cloud task delegation, persistent memory, infinite sessions, and full MCP support. Developers can also choose different models at each stage using explore, plan, and review workflows.
By exposing these capabilities through the SDK, GitHub enables Copilot to run in any environment. Teams can build AI-powered GUIs, internal enterprise agents, productivity tools, or custom workflows.
GitHub teams have already used the SDK to create tools such as YouTube chapter generators, custom agent interfaces, speech-to-command desktop workflows, summarization tools, and even games that let users compete with AI.
GitHub positions the Copilot SDK as an execution platform, giving developers full control over what they build on top of Copilot’s agentic foundation.
