GitHub Copilot SDK Lets Developers Embed Agentic AI in Any Application

Jan 22, 2026 · Updated Apr 25, 2026

GitHub released the Copilot SDK, a programmable interface that exposes the same agent runtime powering Copilot CLI as an embeddable library. Available for Node.js, Python, Go, and .NET, the SDK handles planning, tool invocation, and file edits through JSON-RPC communication with the Copilot CLI running in server mode. You define custom agents, skills, and tools - the runtime handles execution.

The SDK supports all Copilot CLI models, MCP integration for connecting external tools, BYOK (Bring Your Own Key) for using your own API keys from OpenAI, Azure, or Anthropic without GitHub auth, and multiple authentication methods including GitHub OAuth and environment tokens. This gives developers a production-tested agent runtime without building orchestration infrastructure.

Install via npm install @github/copilot-sdk or the equivalent for your language. The SDK is in Technical Preview and requires either a GitHub Copilot subscription or BYOK configuration.
