Hubspot

This gives Claude direct access to your HubSpot CRM through the Membrane CLI, which handles all the OAuth plumbing and token refresh automatically. You get pre-built actions for the usual suspects: creating and updating contacts, companies, deals, and tickets, plus listing and searching across all of them. The action discovery is nice, you can search by intent with natural language to find what you need. When the canned actions don't cut it, there's a proxy mode that lets you hit any HubSpot API endpoint directly while Membrane still handles auth. Works on the free Membrane tier, which is solid for prototyping. Best for sales and marketing automation tasks where you need Claude to read from or write to your CRM without building a custom integration.
