Frequently asked questions

How do I connect HubSpot to Claude?

You need two things: (1) connect HubSpot to Sequel in your Sequel dashboard under Connections, and (2) add the Sequel MCP config to Claude using the setup shown above. Once both are done, Claude can query your HubSpot data directly.

What HubSpot data can Claude access?

Claude can access any data available through your HubSpot connection in Sequel. Use Sequel's search tool to discover available metrics and dimensions, then execute queries to pull the data you need.

Is my HubSpot data sent to Claude's servers?

Query results are returned to Claude as context within your conversation. Only the data you explicitly ask about is retrieved. Sequel never stores your query results permanently — they exist only for the duration of the tool call.

Do I need a Sequel account?

Yes. You need a Sequel account to connect HubSpot and generate an API key. Sign up free at sequel.sh — no credit card required. Then create a connection to HubSpot and generate an API key from Settings → API Keys.

Can I connect multiple HubSpot accounts?

Yes. Sequel supports multiple connections of the same type. If you have multiple HubSpot accounts or properties, add each as a separate connection in Sequel. Claude will be able to query all of them.
