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 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.
