Codex Plugin

Use the supported Codex integration

OpenAI Plugin Docs Download Codex Plugin

Install this through Codex's native plugin flow by pointing a repo or personal marketplace entry at the local plugin folder. OpenAI's official public plugin directory is still not self-serve, so native install today means local marketplace JSON plus a local plugin path.

Plugin pathplugins/remote-browser-service

Repo marketplace file.agents/plugins/marketplace.json

Personal marketplace file~/.agents/plugins/marketplace.json

Recommended

Repo-local native install

Use this when the agent already has this repo checked out. Paste this into .agents/plugins/marketplace.json at the repo root, restart Codex, open the Plugins UI, then install Remote Browser Service.

Optional

Personal marketplace install

Use this when you want the plugin available across projects. Place the plugin at ~/plugins/remote-browser-service or symlink that path to this repo's plugin folder, then paste this into ~/.agents/plugins/marketplace.json.

Install Flow

Native Codex plugin steps

Ensure the plugin folder exists at ./plugins/remote-browser-service in the repo or ~/plugins/remote-browser-service for a personal marketplace.
Add one of the JSON snippets above to the matching marketplace.json file.
Restart Codex so the marketplace is reloaded.
Open the native Plugins UI, open the marketplace entry, and select Install Plugin for Remote Browser Service.
Start a new thread and ask Codex to use the plugin. Runtime values such as REMOTE_BROWSER_TOKEN are only needed when actually opening a live browser session.

Git repos and npm packages are distribution channels, not the native install source. Codex installs from marketplace entries that point at local plugin folders.
