This MCP server wraps the Codex CLI and exposes it through standard MCP tools for code analysis and editing. You get codex_exec for running Codex commands with file references using @ syntax, plus codex_brainstorm for ideation tasks. It handles sandboxed edits with configurable approval policies, streams progress updates, and supports multiple models including gpt-5-codex and o3. Works across Windows, macOS, and Linux. Reach for this when you want to analyze codebases, refactor code, or generate documentation directly from Claude Desktop or other MCP clients without switching to terminal.
