Add Inline to Your Agent
Use the Inline plugin for ChatGPT desktop and Codex, or install the standalone Inline skill in Claude Code and other agents.
The plugin includes Inline MCP and the skill. The standalone skill can use Inline MCP, the authenticated Inline CLI, or local bridge tools. Neither MCP nor the CLI is universally preferred; the right path depends on the host—such as ChatGPT on iOS or macOS versus Codex with shell access—and the access already available.
ChatGPT desktop
Until Inline appears in the public Plugins Directory, add the Inline marketplace from a terminal:
codex plugin marketplace add inline-chat/inlineRestart the ChatGPT desktop app, select ChatGPT Work or Codex, and open Plugins. Choose the Inline marketplace and install Inline.
Start a new chat after installation. Inline will ask you to sign in when it first needs access.
Codex
Add the public Inline marketplace:
codex plugin marketplace add inline-chat/inlineInstall the plugin:
codex plugin add inline@inlineStart a new Codex session. The Inline skill and MCP tools will be available, and Codex will prompt you to sign in when needed.
You can also open /plugins after adding the marketplace and install Inline interactively.
Install the standalone skill
Use the standalone skill when you do not want the full plugin or your agent does not support it.
npx skills add inline-chat/inline --skill inline --global --agent codex --yesRestart the agent so it discovers the skill. It can use MCP, an authenticated Inline CLI, or local bridge tools depending on what the environment provides. See MCP setup and CLI setup.
Manual installation
Download the complete skills/inline folder from GitHub, including its references and agents folders. Copy it to your agent's global skills directory:
| Agent | Destination |
|---|---|
| Codex | ~/.codex/skills/inline |
| Claude Code | ~/.claude/skills/inline |
| Other agents | Use the skills directory documented by your agent |
Restart the agent, then connect Inline MCP or install and authenticate the Inline CLI if the environment does not already provide an Inline access path.
