# GitHub Copilot SDK

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.

## 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 3.8+ / 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

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.
