Copilot Proxy API

Copilot Proxy API for Claude Code and Codex CLI

Self-hosted GitHub Copilot bridge for Claude Code and Codex CLI with OpenAI Responses, Anthropic Messages, streaming resilience, and context management.

Quick Start

With Node.js and an active GitHub Copilot subscription:

Complete the GitHub sign-in, choose your models, then paste the generated Claude Code command into a new terminal.

Client guides: Claude Code · Codex CLI · Generic OpenAI and Anthropic clients

This is an unofficial, reverse-engineered project. Keep the proxy local, never expose it publicly without authentication, and use it responsibly within GitHub's Acceptable Use Policies and Copilot Terms.

Why This Fork?

This fork keeps the original bridge practical for current coding agents:

- Active maintenance for current Copilot models and client compatibility changes.
- First-class Claude Code support through the Anthropic Messages API and an interactive setup command.
- Codex CLI support through the OpenAI Responses API.
- More resilient agent sessions with streaming keepalives, structured error handling, and context management.
- Built-in usage visibility, quota checks, rate limiting, and manual request approval.

Responsible Use

copilot-proxy-api is an unofficial compatibility project. It is not affiliated with or supported by GitHub, and Copilot API changes may break it without notice.
Keep the proxy private, require --api-key for non-local access, and avoid rapid or bulk automation. Activity that triggers GitHub's abuse controls may restrict or suspend Copilot access. Review GitHub's Acceptable Use Policies and Copilot Terms.
