HubSpot

Gives you MCP access to HubSpot's CRM through the Web API. You can manage contacts, companies, deals, tickets, leads, tasks, and notes, plus work with properties, lists, workflows, the knowledge base, and file uploads. Built by Mindstone with multi-account support and host-orchestrated OAuth, so you can switch between portals without manually juggling tokens. Reach for this when you need an LLM to pull deal stage data, update contact properties in bulk, or draft ticket replies based on CRM context. It's part of a 35-connector monorepo that shares auth patterns and hardening practices across Google Workspace, Slack, Salesforce, and others.
