OpenAI’s Codex gets plugins

OpenAI announced this week that Codex now supports plugins, including third‑party services such as Box, Figma, Linear, Notion, Sentry, Slack, Gmail, and Hugging Face.

Plugins are installable bundles for Codex that package reusable workflows, MCP servers, and app integrations; more than 20 plugins are available at launch.

Plugins work across the Codex app, the CLI, and OpenAI’s VS Code extension, and the Codex UI adds a dedicated Plugins tab under the New Thread button.

In the Codex CLI you can install plugins with the /plugins command; a directory example, the 'build web app' plugin, bundles Stripe, Supabase, and Vercel MCP servers and includes skills to deploy to Vercel and build frontends.

Anthropic’s Claude Code offered plugins earlier this year, and Google’s Gemini CLI has a comparable plugin system.
