# Using Gumloop with Marrow MCP

# Using Gumloop with Marrow MCP

Gumloop can connect to Marrow MCP as a custom MCP server. After you configure it, you can use your Amazon data in Gumloop workflows.

## Prerequisites

* A Marrow account with your Amazon connections set up.
* A Marrow MCP key. Create one in [Marrow MCP Integrations](https://app.marrow.com/integrations/mcp).

## Step 1: Add the MCP server

After you log in, you will see a panel on the right side of the page.

1. Go to the [Gumloop connector page](https://www.gumloop.com/personal/connectors).
2. Click the chevron icon next to the **Add Connector** button, then select **Add MCP Connector**.
3. In the **MCP Server URL** field, enter the Marrow MCP server URL: `https://mcp.marrow.com/mcp/v1`.
4. Click **Connect**.
5. In **Authentication**, select **API Key / Credentials**.
6. In the **Header** field, enter `marrow-mcp-key`.
7. In the **Value** field, enter the Marrow MCP key you created on the [Marrow MCP Integrations](https://app.marrow.com/integrations/mcp) page.
8. Click **Connect**.

## Step 2: Use the connector

1. Start a new Gumloop chat.
2. Type your first prompt. For example, you can send: `Use Marrow to list my sellers.`.
3. Wait for Gumloop to process your request and return the results.
