The GitHub Copilot SDK is a multi-platform SDK from GitHub for embedding the agent runtime behind Copilot CLI in applications and services. It provides SDKs for Node.js/TypeScript, Python, Go, .NET, Java, and Rust, allowing applications to invoke Copilot agent workflows while the runtime handles planning, tool invocation, file edits, and related orchestration. Applications can also define custom agents, skills, and tools.
Each SDK communicates with Copilot CLI running as a server over JSON-RPC. The SDK manages the CLI process lifecycle automatically and can connect to an externally run CLI server. The repository provides package-specific installation and API instructions; the CLI is bundled automatically for Node.js, Python, and .NET, while Go, Java, and Rust generally require a separately available CLI, with application-level bundling features available for Go and Rust.
Standard use requires a GitHub Copilot subscription, and usage follows the Copilot CLI billing model, with prompts counted toward the applicable allowance. A BYOK mode supports API keys from supported providers without GitHub authentication.
