Configure the HubSpot MCP Server

Updated 1 min read

Overview

HubSpot operates an official hosted MCP server at mcp.hubspot.com. Access is authorized through OAuth 2.0.

1. Configure HubSpot

  1. Log in to HubSpot with a super admin account.
  2. Click Development in the top navigation bar, then select MCP Auth Apps in the left sidebar. Click Create MCP auth app in the upper right, enter an app name and description, and set the Redirect URL to your Dtwo gateway’s OAuth callback endpoint — you can find it in the Configuration section of your gateway in the Dtwo UI. Click Create.

2. Add the MCP server to your gateway config

In the mcp_servers section of your gateway configuration add the following entry:

  - name: hubspot
    description: "HubSpot's official hosted MCP server for CRM objects."
    url: https://mcp.hubspot.com/mcp
    transport_type: streamablehttp
    authentication:
      type: oauth
      grant_type: authorization_code
      scopes:
        - oauth
      client_id: "<CLIENT_ID>"
      client_secret: "<CLIENT_SECRET>"
      authorization_url: "https://app.hubspot.com/oauth/authorize"
      token_url: "https://api.hubapi.com/oauth/v1/token"

Replace the placeholder values:

  • <CLIENT_ID> and <CLIENT_SECRET> — come from the application you created in step 1.

3. Deploy and verify

Save the configuration and deploy the gateway.

Then, in your AI client, ask it to authorize HubSpot via the gateway. This opens the HubSpot login screen — sign in as the admin whose permissions the agent should inherit, and approve the consent prompt. Once authorized, confirm the server’s tools appear and run a quick call to make sure the connection works.
