Full read-write Claude connector for HubSpot

Make Claude advance deals and log activity in HubSpot

Stop hand-entering CRM updates after every call. Claude updates the contact, moves the deal stage, and logs the note against the right record inside HubSpot, and any deletion or destructive change waits for your approval.

HubSpot is a CRM and marketing platform where teams manage contacts, companies, deals, and tickets. People want Claude to do more than look records up: to update deals, log activity, and move pipeline work forward inside HubSpot itself.

What is a HubSpot MCP server?

A HubSpot MCP server is a small hosted service that exposes HubSpot's data and actions to Claude over the Model Context Protocol, so Claude can manage contacts, deals, and pipeline inside your own account. We build it as a custom connector with separate read and write tools, and destructive actions stay gated behind your approval.

What can HubSpot's current connector do today?

HubSpot ships an official Claude connector, and it covers a standard tool set: Claude can look up records and create or update core contacts and deals and log activity. It leaves gaps, though, such as custom objects, custom validation rules, larger batch updates, and your own scoping and approval flow. A custom HubSpot connector delivers that fuller coverage with scoped, human-in-the-loop controls.

What does full read-write HubSpot access unlock?

Full read-write HubSpot access lets Claude create and update contacts and companies, advance a deal's stage, log calls and notes against the right record, and assign or update tickets once you approve. The CRM hygiene and pipeline updates that used to mean manual data entry happen where the work already lives.

  • Create or update a contact or company record with new details
  • Advance a deal to the next pipeline stage and update its amount
  • Log a call, email, or note against the right contact or deal
  • Create a follow-up task and assign it to an owner
  • Open, update, or route a support ticket
  • Find every deal matching a query and propose batched updates

Can Claude update deals and contacts in HubSpot?

Yes. The official connector already updates core contacts and deals and logs activity. A custom HubSpot connector goes further, advancing a deal to its next pipeline stage, adjusting the amount, and covering custom objects, all against the right record with the scoping and approval your team needs beyond the standard tool set.

Can Claude log a call or note in HubSpot?

Claude can log a call, email, or note against the matching contact or deal, and create a follow-up task assigned to an owner. It reads the record first, attaches the activity where it belongs, and proposes the update, so the CRM hygiene happens without manual data entry.

Will Claude delete or change HubSpot records without my approval?

No. Read and write tools are separated, and destructive actions like deleting a record are gated behind a confirmation step. Claude can prepare an update, but you decide what runs automatically. The connector authenticates as your account and never gets more access to your pipelines than you already have.

How a HubSpot connector works

We build a small MCP server that authenticates to HubSpot with OAuth and the narrowest scopes the work needs. Read tools (search, fetch record) and write tools (create, update, log) are separated, and destructive or outbound actions like deleting a record require your confirmation. Claude only ever has the access your own HubSpot account already has.

Frequently asked questions

Can Claude update HubSpot deals and contacts, not just read them?
Yes. The official connector already creates and updates core contacts and deals and logs activity. A custom HubSpot connector extends that with fuller coverage, such as custom objects, larger batched updates, and the pipeline scoping and approval flow your team needs, all with write tools mapped to the right record.
Will Claude delete or change HubSpot records without my approval?
No. Read and write tools are separated, and destructive actions like deleting a record are gated behind a confirmation step. Claude can prepare an update, but you decide which actions run automatically and which require your sign-off before they touch your CRM data.
Does the HubSpot connector get more access than I have?
No. The connector authenticates as your account through OAuth and inherits your existing permissions and scopes. It never grants Claude more access to contacts, deals, or pipelines than you already have in HubSpot, and you can revoke that access at any time.
