概要

What is OpenAI Codex MCP Server?

OpenAI Codex MCP Server wraps OpenAI Codex CLI as an MCP (Model Context Protocol) server for integration with Claude. It provides tools to generate, explain, debug, refactor, and secure code using Codex capabilities directly from Claude.

How to use OpenAI Codex MCP Server?

Clone the repository, run ./setup.sh, then start the server using ./run.sh (stdio mode for Claude Desktop) or ./run_sse.sh [port] [host] (SSE mode for Web API). Configure Claude Desktop to use the server by adding an entry with command python /path/to/codex_server.py --mode stdio to the Claude Desktop configuration file. After setup, invoke tools like @openai-codex codex_agent or @openai-codex codex_interactive with relevant parameters.

FAQ from OpenAI Codex MCP Server

What are the prerequisites for using this server?

You need Node.js with npm install -g @openai/codex, Python 3.12 or higher, and a .env file copied from .env.example.

What modes does the server support?

The server supports stdio mode (for Claude Desktop) and SSE mode (for Web API integration).

What tools does the server provide?

Two tools: codex_agent (comprehensive Codex features) and codex_interactive (interactive sessions).

What approval modes are available?

Three modes: suggest (only suggests changes, requires approval), auto-edit (automatic file read/write, asks for shell commands), and full-auto (full autonomy with network‑disabled sandbox).

How does security work in full‑auto mode?

The server runs full-auto mode in a network‑disabled sandbox. File operations are limited to the current working directory, and all shell commands require explicit approval unless in full-auto mode.
