Claude Code Codex MCP (claude-code-codex-mcp)
让 Claude Code 与 Codex 终极合体!
在 Claude Code 终端中直接调用 Codex 的历史会话(Sessions)、挂载后台任务,并自由使用 Codex 中配置的全部高性能大模型。
English Documentation | 中文说明文档
💡 为什么需要这个项目?
在现代 AI 辅助研发中,很多开发者同时使用两款顶尖工具:
Claude Code:Anthropic 官方强大的终端代码自主 Agent。
Codex (Desktop & CLI):支持多元模型底座(如 Gemini 3.8 Flash、DeepSeek Flash、GPT-6、Grok 等)并拥有独立的会话记忆体系与沙箱执行环境。
之前两者是相互割裂的。本 MCP 服务打破了这个壁垒,将 Codex 的核心会话引擎与模型目录暴露为标准 MCP 工具,让 Claude Code 可以:
模型任意借力:随时调用 Codex 中的不同模型进行“双盲会诊”或专项复杂推理。
跨端会话缝合:你在 Codex 桌面版(GUI)里推进了一半的工作,在 Claude Code 里可以直接接着干,无需反复复制 Prompt 与代码。
主从分工协作:Claude Code 作为主脑负责整体架构与交互,把脏活累活丢给 Codex 作为后台 Worker 独立执行并保留历史痕迹。

🚀 快速上手 (Quick Start)
1. 安装与一键配置
克隆仓库后,运行对应的安装脚本即可自动安装依赖、执行自检并注册到 Claude Code:
Windows (PowerShell):
git clone https://github.com/your-username/claude-code-codex-mcp.git
cd claude-code-codex-mcp
.\install.ps1Linux / macOS (Bash):
git clone https://github.com/your-username/claude-code-codex-mcp.git
cd claude-code-codex-mcp
chmod +x install.sh
./install.sh2. 手动注册方式
如果你想手动注册到 Claude Code:
npm install
npm test
claude mcp add -s user codex node /path/to/claude-code-codex-mcp/src/index.mjs检查注册状态:
claude mcp list当看到 codex: node ... - √ Connected 即代表一切就绪!
💬 在 Claude Code 中的使用范例
在终端启动 claude 后,直接使用自然语言:
多模型双盲评审:
“请调用
codex_ask_model,使用gemini-3.8-flash-high模型审查当前目录下的认证逻辑是否存在漏洞。”跨端接力编程:
“列出我刚才在 Codex 桌面端运行的会话,找到关于重构的那个会话 ID,并读取它的最新几轮对话。” “调用
codex_resume_session继续该会话,换成deepseek-flash模型,让它补充单元测试。”后台异步工兵:
“调用
codex_run_task启动一个任务,把项目中的旧版 SDK 替换为新规范,完成后把 Session ID 汇报给我。”
💡 Why this project?
Developers often switch between Claude Code (Anthropic's autonomous terminal coding agent) and Codex (an agent with flexible model support such as Gemini 3.8 Flash, DeepSeek Flash, GPT-6, Grok, etc.).
claude-code-codex-mcp acts as a unified Model Context Protocol (MCP) bridge, enabling Claude Code to:
Switch & Query Codex Models: Access external reasoning models directly within Claude Code.
Unified Session Lifecycle: Read, resume, and fork Codex Desktop & CLI sessions seamlessly.
Agent-to-Agent Delegation: Delegate complex tasks from Claude Code to Codex as a persistent background worker.
