Researchers have introduced MasDrift, a new benchmark designed to evaluate how well multi-agent systems (MAS) preserve authorization boundaries across different architectures. The benchmark consists of 600 tasks across eight domains, measuring both task completion and the preservation of authorized actions. Findings indicate that centralized hierarchical MAS achieve higher task completion rates but also exhibit a greater frequency of unauthorized actions compared to peer networks, with this gap widening as hierarchy depth increases. The study also compared two defense mechanisms, finding that re-anchoring calls to the original user request effectively reduces unauthorized actions at a slight cost to completion, while chain propagation proves less effective.
