Codex now supports plugins: installable bundles that package skills, app integrations, and MCP server configuration for reusable workflows. Plugins are available in the Codex app, CLI, and IDE extensions. You can install curated plugins from the plugin directory, or scaffold a local plugin with @plugin-creator and test it with workspace-scoped or home-scoped marketplaces. Learn more in the plugins documentation.. Every plugin is a folder with a required.codex-plugin/plugin.json manifest and optional supporting files: text my-plugin/.codex-plugin/ plugin.json # Required: plugin manifest skills/ # Optional: packaged skills.app.json # Optional: app or connector mappings.mcp.json # Optional: MCP server configuration assets/ # Optional: icons, logos, screenshots.

Curated plugins and local development. Codex surfaces curated public plugins in the plugin directory.
