This article delves into the security of multi-agent systems, specifically focusing on the A2A and MCP protocols. It argues that while prompt injection is a common concern, the security of agents delegating tasks and using tools requires a more comprehensive approach. The piece outlines critical security layers including LLM guardrails for input/output, protocol security for agent interactions, and runtime policy for overarching control. It also details a threat model for these systems, identifying assets to protect and potential adversaries. AI
IMPACT Enhances understanding of security best practices for multi-agent AI systems, crucial for robust deployments.
RANK_REASON The article provides a detailed guide on security protocols for AI agents, which is a specific tooling/best practice topic.
