Codex MCP
Use MCP servers to give Codex-style coding agents the right repo, GitHub, docs, browser, and security context before asking for implementation or PR review.
Combine GitHub, filesystem, and docs servers so Codex can inspect changed files, linked issues, and project conventions before reviewing.
Add browser and testing context when the review depends on UI behavior, live routes, or generated artifacts rather than static diffs only.
Keep write-capable servers behind approval. Codex workflows should separate read-only review from patch, commit, deploy, and comment actions.
A practical Codex stack starts with read-only repository access, then adds GitHub metadata, documentation lookup, and browser evidence only when the workflow needs it.
If you repeatedly paste diffs, failing logs, package scripts, or review guidelines into Codex, MCP can make the workflow more repeatable and less error-prone.
Treat Codex as a coding agent with tool boundaries. A server that can edit files, push commits, or call deployment APIs should have a clear approval gate and rollback path.
If you are choosing between Codex, Claude Code, Cursor, Devin, Replit Agent, Factory, Cline, and open-source terminal agents, start with the agentic AI coding tools directory.

Use the directory and security checklist to choose a stack, then move into workflow packs when you need prompts, config notes, verification steps, and implementation guidance.
