SummaryAn arXiv paper comparing the Model Context Protocol (MCP) and the Agent2Agent (A2A) protocol for inter-agent coordination in LLM-based multi-agent systems. Through implementation-grounded evaluation against requirements including discoverability, multi-turn conversations, observability, and access control, the authors find MCP offers lower coordination complexity while A2A provides richer native stateful abstractions at greater implementation cost.
Why it mattersImplementation-grounded comparison of two dominant agent protocols against concrete coordination requirements, with explicit trade-offs between complexity and native abstraction support.
