A2A protocol standardizes AI agent-to-agent communication

By PulseAugur Editorial · [1 sources] ·

The A2A (Agent2Agent) protocol is an open specification designed to enable independent AI agents to discover, delegate tasks to, and exchange data with each other. It treats each agent as a black box, abstracting away the underlying models and frameworks. A2A differs from the Model Context Protocol (MCP) by focusing on inter-agent communication rather than an agent's connection to its tools. The protocol features a three-layer architecture supporting various transport bindings like JSON-RPC, gRPC, and HTTP+JSON, with agents advertising their capabilities through an Agent Card. AI

IMPACT Standardizes inter-agent communication, enabling more complex multi-agent systems and potentially reducing integration overhead.

RANK_REASON The item describes a new open specification for AI agent communication, akin to a research paper or technical standard. [lever_c_demoted from research: ic=1 ai=1.0]

    The A2A protocol: how it works, step by step, and how it compares with MCP

    <p>AI systems are no longer just a single model answering questions. We now build specialised <strong>agents</strong> (an HR agent, a booking agent, a code-review agent), often developed by different teams, on different frameworks (LangGraph, CrewAI, ADK, OpenAI Agents SDK…), and…
