Build applications that programmatically interact with GitHub Copilot. The SDK wraps the Copilot CLI via JSON-RPC, providing session management, custom tools, hooks, MCP server integration, and streaming across Node.js, Python, Go, and .NET.
copilot --version)| Language | Package | Install |
|---|---|---|
| Node.js | @github/copilot-sdk | npm install @github/copilot-sdk |
| Python | github-copilot-sdk | pip install github-copilot-sdk |
| Go | github.com/github/copilot-sdk/go | go get github.com/github/copilot-sdk/go |
| .NET | GitHub.Copilot.SDK | dotnet add package GitHub.Copilot.SDK |
The SDK communicates with the Copilot CLI via JSON-RPC over stdio (default) or TCP. The CLI manages model calls, tool execution, session state, and MCP server lifecycle.
