The Missing Layer in Agent Security

Short summary

Current agent security frameworks check individual tool calls but miss multi-step attacks that appear normal in isolation. Agent-envelope adds behavioral monitoring by defining expected workflows, tracking data flows across actions, and enforcing budgets to catch exfiltration patterns. The system integrates with existing policy layers to block agents at both individual-call and behavioral levels.

• •Individual tool-call policies miss multi-step attacks that look innocent in isolation
• •Agent-envelope enforces behavioral boundaries: workflows, data flow rules, budgets, and repetition detection
• •Integrates with existing security layers (mcpfw) to block agents when anomalies cross thresholds
