Get all cards assigned to a specific user, optionally filtered by project
AI agents call get_cards_assigned_to_user to retrieve information from Superthread Mcp Extended without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or queries existing data (cards assigned to a user) without creating, modifying, deleting, or executing anything. It is a pure read operation with no side effects. Severity is low because unauthorized access to task/card assignments has limited blast radius—data leakage of work assignments is a concern but not critical in most contexts.
From the tool's definition Tool name includes 'get_' and description states 'Get all cards assigned to a specific user' with optional filtering. No modification, deletion, or execution described.
