description: Install the B2C Commerce MCP server and skills in Claude Desktop (Cowork) and the ChatGPT desktop app (ChatGPT Work) to run B2C tasks from desktop AI assistants.
---

# Desktop Assistants

Claude Desktop (Cowork) and ChatGPT Work run B2C Commerce tasks from the desktop, outside a
code editor or terminal. Each app installs plugins from its own source, so a plugin
installed in one Claude or ChatGPT surface is not always available in another.

The **b2c-dx-mcp** plugin includes the [B2C MCP](../mcp/) tools, documentation,
and [skill collections](./agent-skills). No separate skills installation is needed.

## Before you start

Install [Node.js](https://nodejs.org/) 22.16.0 or higher. The plugin starts the
MCP server on your computer with `npx`. Connected tasks use your existing
[B2C Commerce configuration](./configuration).

## Claude Desktop (Cowork) {#claude-cowork}

Claude Desktop runs tasks from **Home**; this was previously the separate Cowork
mode. It installs plugins separately from Claude Code. Plugins installed with
`claude plugin install` are available in the **Code** tab, not on **Home**.

1. Add a marketplace with the URL `SalesforceCommerceCloud/b2c-developer-tooling`.
   Keep **Sync automatically** on to receive updates.

   [![Claude Add marketplace dialog with SalesforceCommerceCloud/b2c-developer-tooling entered as the URL and Sync automatically turned on.](/screenshots/claude-cowork-add-marketplace.png)](/screenshots/claude-cowork-add-marketplace.png)

2. Install **b2c-dx-mcp**. Claude warns that the plugin runs a local MCP server
   with access to everything available to Cowork. Select **Continue**.

3. Optionally install skill collections such as **b2c**, **b2c-cli**, or **b2c-ops**
   to load their guidance directly. The MCP already provides them through
   [`skills_read`](../mcp/toolsets#documentation).
4. Start a new task from **Home**. If your message box still shows **Chat** and
   **Cowork** options, choose **Cowork**.

<ExamplePrompt>

> Were there any failing jobs recently on my site?

## ChatGPT Work {#chatgpt-work}

The ChatGPT desktop app runs Codex plugins. Codex shares its plugins between
ChatGPT and the Codex CLI, so installing in either place makes the plugin
available in both. To install in ChatGPT:

1. Open **Settings > Plugins** and select **Add > Add marketplace**. Enter
   `SalesforceCommerceCloud/b2c-developer-tooling` as the source, leave the
   other fields empty, and select **Add marketplace**.

   [![ChatGPT Add plugin marketplace dialog with SalesforceCommerceCloud/b2c-developer-tooling entered as the source.](/screenshots/chatgpt-add-marketplace.png)](/screenshots/chatgpt-add-marketplace.png)

2. Open **Plugins**, select the **Personal** tab, choose **B2C DX MCP**, and
   select **Install plugin**.

To install with the Codex CLI instead:

```bash
codex plugin marketplace add SalesforceCommerceCloud/b2c-developer-tooling
codex plugin add b2c-dx-mcp@b2c-developer-tooling
```


Start a new ChatGPT Work task. To update or remove the plugin, use the
[Codex CLI commands](./agent-skills#codex).

<ExamplePrompt>

> Summarize the current promotions and campaigns on my site. Any schedule conflicts?

ChatGPT online in a browser does not use Codex plugins. To connect it, see
[ChatGPT online](../mcp/#chatgpt).

## Troubleshooting

| Problem                   | What to check                                                                                                                                            |
| ------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Plugin is missing         | Check that you installed it for this surface. Claude Desktop (Cowork) and Claude Code install separately; ChatGPT and the Codex CLI share Codex plugins. |
| Server does not start     | Run `node --version` and confirm Node.js 22.16.0 or higher. Restart the app after installing Node.js.                                                    |
| Wrong project or instance | Specify the intended project or named instance in your request.                                                                                          |
| Old tools or skills       | Update the marketplace or plugin, then start a new task.                                                                                                 |
| Artifact shows no data    | Cowork artifacts cannot call local MCP tools. Embed the data and refresh it with a scheduled task.                                                       |
