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 and connecting an MCP server in developer mode.
