Prerequisites

Before you connect Zilliant MCP Server to ChatGPT, make sure that:

• You have a ChatGPT account on a plan that allows you to enable developer mode, such as Pro, Team, Enterprise, or Edu.

• Your Zilliant tenant has MCP access enabled. If it is not enabled, contact your Account Executive or Customer Success Manager.

• Your tenant is configured for OAuth.

• Your OAuth credentials are stored in AWS Secrets Manager for the target environment.

• The Salesforce Connected App includes this OAuth callback URL:

  https://api-{yourTenant}-{yourEnvironment}.zilliant.com/mcp/oauth/callback

Tip

Replace {yourTenant} and {yourEnvironment} with the values for your company. Your Zilliant representative can provide the correct values.

Turn on developer mode

You must turn on developer mode before you can add an MCP connector. You only need to do this once for your ChatGPT account.

1. Open ChatGPT in a browser or in the desktop app.

2. In the bottom left corner, select your name or icon, then select Settings.

3. From the left panel, select Apps.

4. Select Advanced settings, then turn on Developer mode.

Create the connector

After enabling developer mode, create a connector for Zilliant MCP Server.

1. In ChatGPT, select your name or icon, then select Settings.

2. From the left panel, select Apps & Connectors.

3. Select Create.

4. In the connector dialog:

   • Enter a name for the connector, such as Zilliant Tools.

   • Enter the Zilliant MCP Server URL provided by Zilliant Support. The URL should have the following format:

     https://api-{yourTenant}-{yourEnvironment}.zilliant.com/mcp/sse

   • From the Authentication dropdown list, select OAuth.

5. Select Create.

6. Select the connector, then select Connect if visible. If you see Disconnect, the connector is already enabled, and you don’t need to do anything.

Note

ChatGPT expects the Server-Sent Events endpoint. On the Zilliant MCP server, this endpoint is available at /mcp/sse. If the connection does not work, try this URL instead:
https://api-{yourTenant}-{yourEnvironment}.zilliant.com/mcp

The exact endpoint can depend on the FastMCP version used in your environment.

Sign in the first time you use the connector

The first time you use Zilliant MCP Server connector in a conversation, ChatGPT opens a Salesforce sign-in window.

1. Start a new conversation in ChatGPT.

2. Enter a prompt that uses the connector, such as “What Zilliant pricing tools are available?”

3. When ChatGPT asks you to connect, select Connect.

4. In the Salesforce sign-in window, sign in with the credentials for your tenant.

5. Finish the sign-in process.

After you sign in, the pop-up window closes, and ChatGPT completes the request automatically.

Tip

Your session remains active in the workspace. Until your token expires, you do not need to sign in again for later requests.
