Why agent-to-agent communication matters
A single agent can run simple workflows. Real business systems often need specialized agents: intake, research, content, QA, reporting, and handoff. Agent-to-agent protocols aim to make that coordination safer and more interoperable.
Google created Agent2Agent as an open protocol for secure agent-to-agent communication, and the Linux Foundation announced the Agent2Agent Protocol Project in 2025.
How this applies to business kits
A roofing kit might use a lead intake agent, local SEO agent, review agent, and reporting agent. The handoff between those agents needs a shared task state and clear authority boundaries.
Without a handoff contract, multi-agent systems become noisy. Each agent may repeat work, lose context, or take actions another agent was supposed to verify.
The safe design pattern
Use one orchestrator agent, specialized worker agents, and a human approval role. Worker agents prepare outputs. The orchestrator checks state and routes tasks. The human approves anything external.
The key is not maximum autonomy. The key is traceable delegation: who did what, why, with which inputs, and what still needs approval.
FAQ
Do small teams need multi-agent systems?
Not at first. Start with one reliable agent and split roles only when the workflow benefits from specialization.
How does A2A relate to MCP?
MCP connects agents to tools and context. A2A-style protocols connect agents to other agents or agent services.
