MCP and A2A protocols compared for LLM agent coordination

A new paper compares two protocols, Model Context Protocol (MCP) and Agent2Agent (A2A), for inter-agent coordination in LLM-based systems. The study found that MCP offers a simpler implementation with lower coordination complexity, though it requires explicit application-layer management for conversational state and task lifecycles. A2A, conversely, provides more robust native support for stateful, multi-turn coordination but introduces greater implementation and coordination complexity. AI

IMPACT Provides insights into protocol design trade-offs for LLM agent systems.
