get_all_tasks
AI agents call get_all_tasks to retrieve information from Amazing Marvin MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves task information without modifying, deleting, or executing operations. It has no side effects and fits the Read category. Severity is low because task list retrieval poses minimal risk even if misused by an AI agent.
