HubSpot MCP server
Quick answer
HubSpot's MCP server lets Claude read and query your CRM: contacts, companies, deals and properties, including counts and breakdowns. We tested it read-only in September and October 2026, for analysis, and it did that job well. We have not used it to write, so this page stays on reading.

- Official (HubSpot)
- How it runs
- Hosted remote server, sign in with OAuth; a separate local server exists for developers

What your assistant can do with it
- Query CRM data with counts, totals and breakdowns
- Search and read contacts, companies and deals
- Read properties and the account's schema, including custom objects
- Read account and organisation details
How to connect it
- Add the HubSpot connector in Claude and sign in with OAuth.
- Start with a question about your account details, to check which portal you are connected to.
- For app or CMS development, HubSpot ships a separate local developer server; it is not the one for CRM data.
How we use it
We used it for analysis: reading a CRM's shape and answering questions like how many companies sit in each segment, before deciding what to load. All of it read-only, in September and October 2026.
Where it breaks
- We tested reading only. We have no first-hand view of its writes, so check them yourself before you rely on them.
- Several portals can sit behind one login: confirm which one you are reading before you draw any conclusion.
Our take. Good for asking your CRM questions in plain language. For writes, test on a sandbox portal first; we have not.
Frequently asked questions
Is there an official HubSpot MCP server?
Yes. HubSpot publishes a hosted MCP server for CRM data, and a separate local server for developers building apps and CMS assets.
Can Claude update HubSpot records through MCP?
We only tested reading. Try writes on a test portal before using them on real data.
What is the difference between the HubSpot MCP server and the developer MCP server?
The first gives AI tools access to your CRM data. The developer server is a local tool for building HubSpot apps and CMS assets.
