How to Connect HubSpot to Claude with CorpusIQ MCP

Sales teams spend more time updating and navigating HubSpot than they do selling. Connecting HubSpot to Claude via CorpusIQ's MCP platform flips that dynamic — Claude becomes a natural language interface to your entire CRM. Ask "What deals are closing this month?", "Show me contacts who haven't been contacted in 30 days", or "What's our pipeline by stage and rep?" and get instant, accurate answers drawn from your live HubSpot data.

The integration uses the Model Context Protocol (MCP), an open standard that CorpusIQ implements to connect Claude to business tools. Setup is point-and-click OAuth — no APIs to configure, no code to write, no developer required.

Why Connect HubSpot to Claude?

HubSpot is the system of record for your customer relationships, sales pipeline, and marketing contacts. But extracting insights from HubSpot typically means building dashboards, running reports, or manually clicking through records. Claude eliminates that friction by letting anyone on your team ask natural language questions and receive instant answers from live CRM data.

Key benefits of connecting HubSpot to Claude:

  • Pipeline intelligence in seconds. Ask "What's the total value of deals in the negotiation stage?" and get the answer without opening HubSpot.
  • Contact research at conversational speed. "Tell me everything about [company]" returns contact, deal history, and recent activity in one response.
  • Sales coaching and accountability. "Show me deals that haven't had activity in 14 days" helps managers identify stalled opportunities.
  • Cross-source revenue intelligence. Combine HubSpot pipeline with QuickBooks actuals, Stripe payments, or Shopify orders for a complete revenue picture.
  • Meeting prep automation. Before a call, ask Claude "Give me the full history for [contact/company]" for instant briefing.

How the Integration Works

  1. Connect HubSpot via OAuth. CorpusIQ requests read-only access to contacts, companies, deals, and associated records.
  2. Ask Claude any question about your CRM data — pipeline, contacts, companies, deal status, activity history.
  3. CorpusIQ executes the appropriate HubSpot API calls using your stored credentials.
  4. Claude presents the answer in natural language, with context and actionable recommendations.

All communication is encrypted. CorpusIQ never stores your CRM data — every query is a live API call.

Setup Steps

  1. Log into CorpusIQ and go to Connectors.
  2. Select HubSpot from the integration list.
  3. Click "Connect HubSpot" — you'll be redirected to HubSpot's OAuth screen.
  4. Authorize read-only access to contacts, companies, deals, and associated records.
  5. Return to CorpusIQ. Start asking Claude CRM questions immediately.
