Really cool, but it seems like recursive agents are going to bog down into microservice hell.
I don't know of a usecase where there are such deep recursive agent chains that it becomes unmanageable.
I almost think of mcp-agents as a modern form of scripting – we have agent workflows (e.g. generating a summary of new GitHub issues and posting on Slack), and exposing them as MCP servers has enabled us to use them in our favorite MCP clients.
