HubSpot MCP server: connect AI agents to HubSpot from the EU

HubSpot is a CRM and marketing platform used by many small and mid-sized companies in Europe, made by HubSpot, Inc. of Cambridge, Massachusetts. Teams use it for contacts, deals, support tickets, email marketing and websites.

HubSpot's remote MCP server runs at https://mcp.hubspot.com and has been generally available since April 2026. It uses OAuth 2.1 with PKCE. Agents can read and write CRM records and engagements, while marketing content and account context are read-only. Every call respects the HubSpot permissions of the user who authorised the connection.

Before a sales call, an agent can pull the company record, open deals, recent emails and support tickets and write a one-page brief. After the call, it can log a note, create follow-up tasks and move the deal stage once a person confirms.

Support leads can ask "which customers with open tickets have a renewal this quarter?" and get a list with links. Marketing teams can have an agent summarise how a campaign's emails and landing pages performed and suggest which contacts to follow up.

In your HubSpot account, a super admin creates an MCP connector, which gives you the client details the agent needs. Add the HubSpot connector on inference.eu, enter those details and sign in with HubSpot through OAuth.

The agent then acts with that user's permissions, so a user with limited team or record access keeps the agent within the same limits. Tokens are stored encrypted in the EU and used only by the agents you allow. Admins can uninstall the connector in HubSpot at any time to cut off access.

CRM records are fetched from HubSpot's own MCP server, so data stays with HubSpot, a US company, as it does for your other HubSpot integrations. HubSpot accounts can be hosted in its EU data centre; check which region your account uses.

On inference.eu, the model that reads and writes CRM data runs in EU data centres, and your HubSpot credentials are stored encrypted in the EU. A CRM holds personal data about customers and prospects, so connect agents with users whose access matches the task and avoid broad super admin accounts.

Wrong CRM updates have consequences: a changed deal stage can trigger workflows, a changed owner moves a customer to another rep, and edited contact data can affect consent and email sends.

On inference.eu you can let searches and reads run on their own and require a person's approval before an agent creates or updates records, logs engagements or changes deal stages. The approval shows the record and the fields that will change. HubSpot's property history shows previous values if something needs to be put back.
