MCP & ChatGPT

Last updated: October 21, 2026

Connect Marqii to ChatGPT to access Marqii tools directly from your conversations.

The first time you connect, you'll be prompted to sign in to your Marqii account and authorize the connection. Once authorized, you can start using Marqii in ChatGPT.

Before You Begin

• You must have access to custom MCP connectors in ChatGPT. Availability depends on your ChatGPT plan and workspace permissions.

• Setup must be completed in the ChatGPT web interface.

• You'll need your Marqii login credentials to authorize the connection.

1. Open ChatGPT Settings

  1. Open ChatGPT in your web browser.

  2. Open your profile menu and select Settings.

  3. Navigate to Apps or Plugins, depending on the interface available to your account.

2. Add Marqii as a Custom Connector

  1. Open the Plugins section.

  2. Select the + button and choose Add custom MCP server.

  3. Enter the following details:

    Name: Marqii

    Server URL: https://mcp.marqii.com/mcp

  4. Select OAuth as the authentication method, if prompted.

  5. Review the security warning and confirm that you want to continue.

  6. Select Create as a plugin to create the connection.

Note: ChatGPT's interface and available options may vary by account. If you don't see these options, check with your ChatGPT workspace administrator.

3. Authorize Your Marqii Account

  1. When prompted, sign in using your existing Marqii account credentials.

  2. Review and approve the requested authorization.

  3. Return to ChatGPT once the connection is complete.

You should now be able to use Marqii through ChatGPT.

4. Test Your Connection

  1. Start a new ChatGPT conversation.

  2. Open the tools menu and select Marqii, or mention the connector in your prompt if that option is available.

  3. Enter a prompt that uses Marqii data or functionality available to your account.

For example, you could ask ChatGPT to retrieve information using the Marqii tools available to you.

ChatGPT may ask you to confirm certain actions before they are completed.

Troubleshooting

I don't see the option to add a custom MCP server.

Your ChatGPT plan or workspace permissions may not support custom connectors. Contact your workspace administrator to confirm access.

I'm unable to authorize my Marqii account.

Confirm that you can sign in to Marqii normally, then try the authorization process again.

My connection isn't working as expected.

Verify that Marqii is selected in your ChatGPT conversation and that the requested functionality is available to your account.

If you still need help, contact Marqii Support at support@marqii.com or text (512) 967-3739.
