From Privacy to Workflow Integrity: Communication-Graph Metadata in Autonomous Agent Interoperability
Researchers identify a critical vulnerability in agent-interoperability protocols like A2A and MCP: while message content is encrypted, the communication metadata revealing which agents contact each other, when, and how often exposes pending workflows and enables adversaries to predict and preempt autonomous actions. The study demonstrates that observers can infer task classes from metadata patterns alone and that metadata-protecting transports significantly reduce this predictive leverage.
