# Adding MCP to ChatGPT app (beta)

Add Avici as a personal ChatGPT plugin backed by Avici’s hosted MCP server.

The plugin is what you install and use inside ChatGPT. The MCP server provides the secure connection to your Avici account.

> **Desktop and Work required**
>
> Complete setup from ChatGPT Work in a desktop browser.
>
> Plugins are not available in regular Chat, the IDE extension, or mobile.

> **Beta**
>
> Avici is not yet published in ChatGPT’s official plugin directory. For now, create it as a personal custom plugin.
>
> ChatGPT will display an unreviewed MCP server warning during setup. The official Avici plugin is coming soon.

### Before you start

You need:

* Access to ChatGPT Work
* A desktop web browser
* Developer mode enabled
* Access to the email attached to your Avici account
* An internet connection

### Enable developer mode

1. Open ChatGPT in a desktop browser.
2. Open **Settings**.
3. Select **Security and login**.
4. Turn on **Developer mode**.

Developer mode availability may depend on your account and workspace policy.

### Open the Plugins directory

1. Turn on **Work** in the ChatGPT switcher.
2. Open **Plugins**.
3. Select the **+** button.
4. The **New Plugin** window will open.

### Create the Avici plugin

| Field          | Value                                                                        |
| -------------- | ---------------------------------------------------------------------------- |
| Icon           | Optional                                                                     |
| Name           | `Avici`                                                                      |
| Description    | `View your Avici wallet, cards, balances, spending, and refunds. Read-only.` |
| Connection     | `Server URL`                                                                 |
| Server URL     | `https://mcp.avici.money/setup`                                              |
| Authentication | `OAuth`                                                                      |

Enter the following details:

Then:

1. Review the custom MCP server warning.
2. Select **I understand and want to continue**.
3. Select **Create**.
4. Wait while ChatGPT connects to the Avici MCP server and discovers its tools.

The warning is expected because Avici has not yet completed publication in ChatGPT’s official plugin directory.

### Connect your Avici account

When ChatGPT prompts you to connect Avici:

1. Open the secure Avici login page.
2. Enter the email attached to your Avici account.
3. Request a one-time code.
4. Enter the code on the Avici login page.
5. If more than one Avici account is available, select the account you want ChatGPT to use.
6. Return to ChatGPT after approval.

> **Security note**
>
> Enter the one-time code only on the Avici login page. Never post it inside a ChatGPT conversation.

### Use the Avici plugin

1. Start a new ChatGPT Work conversation.
2. Select the **+** button beside the composer.
3. Open the **More** menu and select **Avici**.

You can also type `@Avici` in the composer to select the plugin directly.

Then ask:

“Show me my Avici account.”

### Example questions

* “What is my Avici wallet balance?”
* “Show my token holdings by network.”
* “How much is available to spend on my card?”
* “Show my latest card purchases.”
* “Have I received any refunds?”

### What ChatGPT can access

After connecting, the Avici plugin can read:

* Your wallet balance and token holdings
* Your cards and available spending power
* Your card purchases
* Your transaction activity
* Your refunds

Avici is read-only. It cannot send, swap, top up, withdraw, bridge, transfer, approve, or otherwise move money.

### If the plugin does not connect

Confirm that:

1. You are using ChatGPT Work in a desktop browser.
2. Developer mode is enabled.
3. **Connection** is set to **Server URL**.
4. **Authentication** is set to **OAuth**.
5. The server URL is entered exactly as `https://mcp.avici.money/setup`.
6. Your browser allows the Avici login window to open.

If it still fails, remove the custom plugin and create it again.

### Current limitations

* Plugins require ChatGPT Work on a supported desktop surface.
* Setup is not available from mobile.
* Avici displays an unreviewed MCP warning until the official plugin is published.
* Full card details require local decryption. Use the Avici CLI with Codex for that request.

### Remove the Avici plugin

1. Open **Plugins**.
2. Find **Avici** under your personal or installed plugins.
3. Open its options.
4. Select **Uninstall** or **Remove**.

You can create and connect the plugin again whenever needed. Platform references: [ChatGPT plugins](https://learn.chatgpt.com/docs/plugins) and [connecting an MCP server in developer mode](https://developers.openai.com/plugins/deploy/connect-chatgpt).
