# GitHub Copilot SDK > Build applications that programmatically interact with GitHub Copilot > **Staleness Watch**: See [EXTERNAL-API-REGISTRY.md](../../EXTERNAL-API-REGISTRY.md) for source URLs and recheck cadence 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. --- ## Prerequisites - **GitHub Copilot CLI** installed and authenticated (`copilot --version`) - **GitHub Copilot subscription** (Individual, Business, or Enterprise) — not required for BYOK - **Runtime:** Node.js 18+ / Python 3.10+ / Go 1.21+ / .NET 8.0+ ## Installation | 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` | --- ## Architecture ```text Your App → SDK Client → [stdio/TCP] → Copilot CLI → Model Provider ↕ MCP Servers ``` **Transport modes:** | Mode | Description | Use Case | |------|-------------|----------| | **Stdio** (default) | CLI as subprocess via pipes | Local dev, single process | | **TCP** | CLI as network server | Multi-client, backend services | --- ## Core Pattern: C
