Better auth support is needed for MCP. It is holding back connectors and end user adoption! In the meantime, excited to see #HubSpot add User-Level Permissions as a requirement for the app marketplace. This applies to AI connectors that primarily connect to gen AI assistants or agents. Check out our Dev Changelog for more details but the TLDR is To list an AI connector on the HubSpot Marketplace, developers must rebuild their app using the official HubSpot MCP server (BETA), which enforces user-level permissions. Only CRM read operations are currently available. These requirements maintain the same user-level access guardrails implemented in our own connectors.
