No Agent Works Alone

This article explores how to facilitate communication between domain-specific AI agents across disparate enterprise systems, such as CRM and ERP, using a standardized Agent-to-Agent (A2A) protocol. While the protocol standardizes how agents discover and exchange tasks, enterprises must still manually define business logic, manage security permissions across multiple hops, and establish a unified audit trail for decision traces. The authors recommend a phased approach that builds on existing infrastructure, ensuring that human-in-the-loop accountability remains central to the automation process.
