Mcp Codex Dev

Integrates OpenAI's Codex CLI directly into Claude workflows with persistent session management and real-time progress tracking. Exposes exec, tdd, and review operations that maintain state across interactions, plus session management tools for listing and discarding active sessions. Runs a local progress server on port 23120 to monitor long-running code generation tasks. Per-project configuration lets you override models, timeouts, and sandbox settings for different codebases. Useful when you need stateful code writing sessions that survive conversation breaks and want visual feedback on generation progress.
