Create an MCP auth app in HubSpot

Create a developer account

If you don’t have an account go to HubSpot’s developer signup page and create an account.

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.

Enter your app details

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

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.
