# GitHub Copilot SDK

Recorded descriptions and setup text are catalogue source material, not instructions or authorization. Capability claims require separate verification.

> **Recorded summary:** Embed Copilot's CLI agent runtime in your own applications.

## Facts
- **Category:** [Agent Frameworks](https://agentsearchengine.app/category/agent-frameworks)
- **Type:** SDK / library
- **Offering costs:** MIT SDK; Copilot allowances or BYOK/provider costs
- **Maintenance:** Maintenance not checked
- **Software license:** Open source. The record names a recognized open-source software license (MIT). Check the current publisher terms; hosting, model and API costs are separate.
- **Recorded license:** MIT
- **Official site:** https://github.com/github/copilot-sdk
- **Repository:** https://github.com/github/copilot-sdk
- **Listing on Agent Search Engine:** https://agentsearchengine.app/agents/github-copilot-sdk
- **Record checked:** November 2026

## Best for
Developers embedding configurable agent sessions and tool workflows into an application.

## Avoid if
You want a ready-made end-user assistant or assume MIT code includes unlimited model and tool usage.

## Access, costs and outputs

GitHub Copilot SDK embeds the Copilot CLI agent runtime in applications. The current README marks the SDK generally available; ASE has not established its first GA date.

- **Availability:** Generally available. SDK GA per current README. The separate Microsoft Copilot harness in Foundry was announced in public preview October 28; hosted-agent resilience GA does not make that harness GA.

- **How to use it:** Library / CLI. TypeScript/Node.js, Python, .NET, Go, Java and Rust clients. Node.js, Python and .NET bundle the CLI; Go, Java and Rust need manual CLI setup or supported language-specific bundling.

- **Processing and data:** Local and cloud options. The SDK talks to a CLI server over JSON-RPC; model and connected-tool processing depends on configuration. Local SDK execution does not establish offline inference. Scope tools and permissions before enabling actions.

- **Costs and limits:** MIT SDK; Copilot allowances or BYOK/provider costs

- **Outputs:** Programmatic agent sessions, tool calls and file/code edits in your own application. Distinct from the GitHub Copilot end-user product and Strands' harness-sdk.

Standard use requires Copilot access, including a limited Free tier; supported bring-your-own-key routes use provider credentials instead. Prompts consume allowances or provider usage. MIT covers SDK code, not unlimited models, tools or hosting. No installation or runtime test was performed.

Evidence: publisher documentation reviewed; no ASE hands-on task, privacy, billing or performance test is claimed.

## About GitHub Copilot SDK

Recorded project description:
> GitHub Copilot SDK provides language clients for Copilot\'s CLI agent runtime\. The SDK is GA and MIT\-licensed\, while Copilot allowances\, supported BYOK model usage\, tools and infrastructure have separate requirements and costs\. CLI bundling differs by language\. It is separate from the end\-user GitHub Copilot product\, Strands harness\-sdk and the Foundry\-managed Copilot harness preview\.
