# How to register your own HubSpot MCP OAuth app

> Create an MCP auth app in HubSpot and connect it to Nango

This guide shows you how to create an **MCP auth app** in your HubSpot account and obtain your OAuth credentials (client ID and secret). These are required so your users can grant your app access to their HubSpot account via Nango.

## Create an MCP auth app in HubSpot

**1. Create a developer account**

If you don't have an account go to [HubSpot's developer signup page](https://app.hubspot.com/signup-hubspot/developers) and create an account.

**2. Open MCP Auth Apps**

In your HubSpot account, go to **Development**. In the left sidebar, select **MCP Auth Apps**.

**3. Create a new MCP auth app**

In the upper right, click **Create MCP auth app**.

**4. Enter your app details**

In the dialog, fill in all your required information. For the **Redirect URL** add `https://api.nango.dev/oauth/callback`

**5. Create and copy credentials**

Click **Create**. After the app is created, copy your **Client ID** and **Client Secret**. You will enter these when configuring the HubSpot (MCP) integration in Nango.

You're now ready to connect HubSpot MCP to Nango. For more on the HubSpot MCP server and OAuth, see [HubSpot's guide to integrating with the MCP server](https://developers.hubspot.com/docs/apps/developer-platform/build-apps/integrate-with-the-remote-hubspot-mcp-server).
