Summary

A Hacker News user asks if anyone is using Google's A2A agent-to-agent protocol, noting confusion six months ago and the rise of MCP, but now seeing potential for agent interaction.

The A2A protocol is an agent to agent protocol from Google. I was looking at it 6 months back but it didn&#x27;t feel like I really understood how to use it at that point. Probably because we were all still trying to figure out agents and then the MCP protocol became quite a big deal. But now I&#x27;m starting to think that once an agent has tools and services and data and then contacts. Actually, the point of interaction becomes the agent itself and then if you build other agents you would want them to interact because they have the most relevant context and ability to answer whatever queries. So I was just curious to know if anyone is using this yet?<p><a href="https:&#x2F;&#x2F;github.com&#x2F;a2aproject&#x2F;A2A" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;a2aproject&#x2F;A2A</a>

Is MCP actually reducing integration work for agents?

Reddit r/AI_Agents

The article explores whether the Model Context Protocol (MCP) effectively reduces integration work for AI agents by standardizing agent-tool communication, comparing native MCP integration in Evose to manual wiring in other stacks like LangGraph and CrewAI.
