Codex CLI integration

Copy for LLM

Codex is OpenAI's agentic coding tool. The Codex CLI runs in your terminal, reads and edits your codebase, runs commands, and completes multi-step development tasks.

The Apify plugin for Codex connects Codex to Apify's library of Actors and bundles:

This guide covers installation in the Codex CLI. To use Codex in the ChatGPT desktop app instead, see the Codex in the ChatGPT desktop app guide.

Authenticate to Apify

The plugin bundles the Apify MCP server. Read-only tools like searching Apify Store and fetching Actor details work without signing in, but you need to authenticate to run Actors and access your account data.

  1. The first time Codex calls a tool that requires authentication, such as running an Actor, it opens a browser tab for the Apify OAuth flow.

  2. Review the permissions and select Allow access.

  3. Back in the terminal, the apify MCP server is connected and ready to use in any new chat.

Session persistence

The connection stays authenticated for future sessions. You can revoke access at any time in Apify Console > Settings > Integrations.

Run your first prompt

In any new Codex CLI chat, describe what you want in natural language. Because this bundle exposes the MCP tools and skills directly, be explicit about the workflow you want.

Use Apify to find a good Actor for scraping Google Maps places. Show me the best option, its input requirements, pricing model, and what kind of dataset output it returns. Do not run the Actor yet.

Codex searches Apify Store and fetches the top Actor's details through the apify MCP server.

It then summarizes the Actor's inputs, pricing, and output - all without running the Actor.

Example prompts that route to specific skills:

To run apify-ultimate-scraper:

Find 10 highly rated coffee shops in Seattle with name, address, rating, phone, and website.

To run apify-actor-development:

Create an Apify Actor that accepts a startUrl and maxPages input, crawls the site, and stores each page title and URL.

To run apify-sdk-integration:

Add Apify to this project. The Node.js API route should run an Actor and return dataset items as JSON.

Troubleshooting

The /plugins command does not appear

Plugins require a local installation of the Codex CLI with plugin support enabled. Install or update the Codex CLI locally, then run /plugins again.

The Apify plugin does not appear in the list

Reopen /plugins, move to the Apify Plugin tab, and confirm the marketplace was added. If the Apify plugin still doesn't appear, re-add the marketplace using the repository apify/apify-codex-plugin.

Browser doesn't open, or OAuth fails

If the browser doesn't open automatically, copy the OAuth URL shown in the terminal and paste it into your browser manually.

If you're running the Codex CLI in a headless environment (SSH, remote container) or the OAuth flow still fails, authenticate with an API token instead. Copy your token from Apify Console > Settings > Integrations and set it before starting Codex:

export APIFY_TOKEN=<YOUR_API_TOKEN>
