The Amazon Bedrock AgentCore Gateway, while useful for controlling agent tool calls with Cedar policies, has limitations in detecting malicious sequences. The gateway lacks session memory, allowing agents to execute harmful actions by chaining seemingly innocuous steps that individually pass policy checks. Additionally, the gateway does not monitor model API calls, enabling agents to exfiltrate sensitive data provided through tool access directly to model providers like Anthropic or OpenAI. To address these gaps, the author proposes SwarmSentinel for tool path integrity and SwarmSheriff for model path security, introducing concepts like Agent Security Policy (ASP) and taint propagation.
