Retrieve lists that a specific user is a member of.
AI agents call getUsersListMemberships to retrieve information from Xdevplatform/xmcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns membership data about a user, with no side effects, data modification, execution capabilities, or destructive operations. It is purely informational retrieval, placing it firmly in the Read category with low severity since leaked membership data is typically not critical.
From the tool's definition Tool name and description indicate retrieval operation: 'Retrieve lists that a specific user is a member of' — a query that returns membership information without modifying data.
