From Privacy to Workflow Integrity: Communication-Graph Metadata Threat in Autonomous Agent Interoperability

A recent study published on arXiv formalizes the threat model for communication-graph metadata in autonomous agent interoperability protocols such as A2A and MCP. The research finds that while message content is protected, the graph of which agent contacts which, when, and how often can reveal pending workflows with high precision, enabling an adversary to act before the workflow completes. The paper argues this constitutes a workflow integrity risk rather than a mere privacy violation, and evaluates candidate transports to mitigate the leak.
