If you have the Mighty Ads plugin, connect MightyAI from its account settings. Complete browser sign-in and choose the workspace containing your brand.

Need the plugin or skills package? [Contact MightyAI](https://www.getmighty.ai/contact) for the current Codex setup files.

## Find the plugin

### 1. Open Plugins

In the desktop app, open **Plugins** to browse the shared ChatGPT and Codex plugin directory. Use the Mighty Ads installation link supplied to you if the plugin is not listed in your directory.

### 2. Install the supplied plugin

Open the Mighty Ads plugin from its installation link and follow the install prompts. If MightyAI supplied an archive for upload, use **Add → Upload plugin archive** in the shared directory. Package formats differ by client; use the Codex package provided to you.

### 3. Connect your account

Open the installed plugin's account settings, connect MightyAI, and complete browser sign-in. Select the workspace containing your brand, then start a new Codex chat.

See [OpenAI's plugin guide](https://learn.chatgpt.com/docs/plugins) for supported surfaces. The screenshot above shows the shared directory on the web; the desktop app's layout can differ.

## Set up a direct connection

### Ask Codex

### Ask Codex to connect

You can ask Codex to help:

<Prompt title="Try this request">
Help me connect MightyAI using the direct MCP server named mighty at https://api.mightyai.app/mcp. Check existing connections first and reuse a matching connection. Ask me before replacing a connection that points somewhere else. Start browser sign-in and help me select my workspace. Do not make advertising changes.
</Prompt>

A direct connection does not install Mighty Ads skills. If MightyAI supplied a skills ZIP separately, attach it in Codex and ask it to install those skills as well.

### Terminal

### Run the setup commands

Check existing connections first:

```bash
codex mcp list
```

If `mighty` is not already configured:

```bash
codex mcp add mighty --url https://api.mightyai.app/mcp
```

Then sign in:

```bash
codex mcp login mighty --scopes mcp:all,user:org:read --oauth-client-registration cimd
```

Complete sign-in and workspace selection in the browser. Restart Codex and open a new chat.

## Check the connection

<Prompt title="Try this request">
Use the mighty connection to list the brands I can access. Ask which one I want to use. Do not make changes.
</Prompt>

Choose your brand and run [your first advertising review](https://mightyai.jamdesk.app/quickstart).

To change the workspace authorized by this direct connection, run `codex mcp logout mighty`, then repeat the login step. Plugin account connections are managed in the plugin's settings.

See [OpenAI's MCP documentation](https://learn.chatgpt.com/docs/extend/mcp?surface=cli) for client configuration.
