Ask HN: Is anyone using the A2A protocol yet?

1•asim•1h ago
The A2A protocol is an agent to agent protocol from Google. I was looking at it 6 months back but it didn'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'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?
