Codex MCP Server

Codex MCP Server (version 1.4.10) is a crucial bridge component designed to integrate OpenAI's Codex CLI with AI agents like Claude Code, providing robust AI-powered code analysis, generation, and review capabilities directly within a developer's editor or IDE. Functioning as an MCP (Model Context Protocol) server wrapper, it translates requests from client applications into commands for the underlying Codex CLI, which then interacts with the OpenAI API. The project maintains an active development pace with frequent patch releases, as evidenced by recent fixes addressing issues like hanging processes and `codex -C` bugs. Its key differentiators include enabling multi-turn conversations with session support, advanced code review features for uncommitted changes or branches, and specialized tools like web search with customizable depth. It requires the globally installed Codex CLI (v0.75.0+) and an authenticated OpenAI API key for operation. The server itself is designed for execution as a command-line process rather than programmatic import into other JavaScript applications.
