Find the Best Codex Plugins and Skills

A skill is one folder with a SKILL.md file that teaches Codex how to do a specific job. A plugin bundles several pieces, such as skills and app or MCP connections, so you install them together. A marketplace is a GitHub repository that distributes many plugins or skills from one place.

Usually, yes. Claude Code and Codex both read skills in the SKILL.md format, so most skills move between them without changes. Check the tools a skill calls, because a skill that depends on a Claude-only tool or a missing command will not run the same way in Codex.

Ask Codex to install it with the built-in skill installer and point it at the skill folder on GitHub, or copy the folder into your Codex skills directory. Start a new thread afterwards so Codex loads it. Each listing here shows the install route for that skill.

Run codex mcp add with the server name and its start command, or add the server to your Codex config file. Remote servers may also ask you to sign in. Every MCP listing here shows the command and the requirements from its documentation.

Use a prompt for a one-off request. Turn it into a skill when you find yourself pasting the same instructions again, because Codex can load a skill on its own when the task matches and you can version it and share it with your team.

Skills are ranked by all-time installs from skills.sh. Plugins and MCP servers are ranked by the GitHub stars of their source repository. Each popular block shows at most one listing per repository. Neither number proves that a listing works in your setup, so read the requirements before you install.

No. Codex Plugin Hub is an independent directory. Every listing links to its original source so you can check it yourself.
