HubSpot MCP Server for ChatGPT, Claude and Grok
Work with HubSpot from the AI assistant your team already uses. The Noca MCP Server lets ChatGPT, Claude and Grok read HubSpot data, run HubSpot workflows and generate documents, with the permissions and approvals you set.
Connect HubSpot to AI Without Building an Integration
Noca already connects to HubSpot. Turn on the Noca MCP Server and that connection becomes available in ChatGPT, Claude, Grok and any MCP-compatible assistant.
Changes run through Noca flows you publish, so every update to HubSpot follows your rules, uses your own credentials and is logged.
What You Can Do With
HubSpot Through MCP
Read HubSpot Data Through Flows
Data-source flows read HubSpot records such as contacts, companies, deals and tickets and return them to the assistant.
Run HubSpot Workflows
run_flow starts published flows that create and update HubSpot records, together with steps in 60+ other systems.
Generate Documents From HubSpot
Fill your Word and PDF templates with HubSpot data and send them for signature.
Build HubSpot Automations in the Chat
With Builder permissions, the assistant can create flows with HubSpot steps, choose the connection and test them.
Your Credentials, Your Rules
Noca uses your own HubSpot connection. Turn on only the permission groups you need.
Approvals and Logs
Set each tool to Always allow, Needs approval or Blocked, and review every run in Noca logs.
Example: HubSpot From Your AI Assistant
Ask: “Send the renewal proposal to every deal closing this month and log it in HubSpot.” Noca runs your renewal flow: it reads the deals, generates each proposal from your template, sends them and logs the activity in HubSpot.

How do I connect HubSpot to ChatGPT or Claude?
