hubspot.props.list
AI agents call hubspot.props.list to retrieve information from G Gremlin Hubspot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and context indicate this performs a read operation—listing HubSpot object properties without modification. However, in a CRM context, property enumeration combined with the server's capability for 'unlimited record extraction' and 'bulk upserts' could enable reconnaissance for data exfiltration or privilege escalation attacks if accessed by an unauthorized agent.
From the tool's definition Tool name 'hubspot.props.list' suggests listing/retrieving properties; server description mentions 'property drift analysis' indicating property enumeration is a core function. Description is empty, reducing confidence slightly.
