HubSpot MCP server

HubSpot × ChatGPT

Use the HubSpot MCP server
in ChatGPT

Contacts, deals, and marketing data from your HubSpot CRM, in your AI. This guide connects HubSpot to ChatGPT (chatgpt.com) through a governed gateway — one URL that also works in every other MCP client you use, with your rules and a full log attached.

Live-probed · Security-scanned · Note: HubSpot currently restricts third-party sign-ins — API-key path recommended

Setup: HubSpot in ChatGPT

ChatGPT adds MCP servers via custom connectors in developer mode. The gateway route takes about two minutes:

  1. Connect HubSpot to your free gate gateway from the verified directory.
  2. Open ChatGPT → Settings → Connectors and enable Developer mode under Advanced.
  3. Click 'Create', name it 'gate', paste your gateway URL, and set authentication to OAuth.
  4. Approve the authorization — HubSpot is now available in your ChatGPT conversations.

What to ask once it’s connected

Which deals are set to close this month?
Summarize this contact's history before my call.
List the contacts from the webinar campaign.
Draft a follow-up based on the last interaction.

Why route it through a gateway

One URL, every client

The same HubSpot connection works in Claude, Claude Code, Cursor, VS Code too — no per-client re-wiring.

Rules before regret

Allow, ask, or block every tool HubSpot exposes — reads can flow freely while writes require your approval.

Every call logged

A plain-language activity log of everything ChatGPT did with HubSpot — searchable, exportable, auditable.

Scanned and probed

HubSpot passed a live handshake probe and a security scan before listing — and drift detection watches it after you connect.
