## AI overview

This article presents A2A as a protocol for enabling agents from different vendors and platforms to hand work to one another in a multi-agent security operations center. It explains that A2A complements MCP: MCP connects agents to data and tools, while A2A connects agents to other agents. The article describes this as a conceptual architecture because production security-agent handoffs mediated by A2A are not yet shipping.
