Codex

About

Codex is a robust Go-based MCP server engineered to seamlessly connect OpenAI's Codex CLI with a diverse array of AI coding assistants, including Claude Code, Roo Code, and KiloCode. By encapsulating the Codex CLI, this tool empowers AI clients to harness Codex's acclaimed capabilities for intricate code implementation and precise bug fixing. It's an invaluable asset for developers seeking to merge the strategic planning of other AI models (such as Gemini 3.0 Pro's KiloCode) with Codex's execution accuracy, offering advanced features like multi-turn session management, adaptable sandbox security, and efficient concurrent processing within a lightweight, self-contained binary.
