Collaborative, agent to agent scenarios

Discussion https://news.ycombinator.com/item?id=43631381

After the release yesterday, I think it's an interesting move from Google, and specially the sample code they have in the repo.

Seems like a natural move after the MCP release, and I'm curious to see how many A2A new tools will appear in the next weeks, has anyone already started working on a Python library to implement the A2A interface?

They say that MCP can be used in conjunction, but I'm not sure if this actually makes the type of interaction move from the MCP (tool) level to the agent level.

Also, the auto-discovery with the well-known/agent.json I think it's something that is missing on the MCP world (?).

What do you think about it?
