Google: New Agent-to-Agent (A2A) protocol to complement MPC

https://developers.googleblog.com/en/a2a-a-new-era-of-agent-interoperability/

> A2A is an open protocol that complements Anthropic's Model Context Protocol (MCP), which provides helpful tools and context to agents. Drawing on Google's internal expertise in scaling agentic systems, we designed the A2A protocol to address the challenges we identified in deploying large-scale, multi-agent systems for our customers. A2A empowers developers to build agents capable of connecting with any other agent built using the protocol and offers users the flexibility to combine agents from various providers. Critically, businesses benefit from a standardized method for managing their agents across diverse platforms and cloud environments. We believe this universal interoperability is essential for fully realizing the potential of collaborative AI agents.

Still not totally sure what it is or how it works, but I like that MCP and I guess now A2A allow composition of agents rather than having to re-invent the wheel every time.
