Codex MCP Bridge

Run OpenAI's background computer-use engine as a local MCP server for Claude Code

Description

A bridge that exposes the OpenAI Codex computer-use engine (found within the ChatGPT Mac app) as a Model Context Protocol (MCP) server. This allows other agents like Claude to perform background clicks and drags on macOS without hijacking the user's cursor.

Prompt

"Set up Codex's computer use as an MCP server for you on my Mac. Find the \"cua_repl\" entry in ~/.codex/plugins/cache/openai-bundled/unified-computer-use/<newest version>/.mcp.json and register it as a user MCP server called \"codex-cu\" with the same command, args and env. Then test it by using Calculator in the background to work out 12 × 12."
