A Technical Taxonomy of LLM Agent Communication Protocols
arXiv (TU München)·low signal
New survey (arXiv 2606.19135, June 17) catalogs the emerging stack of LLM agent communication protocols (MCP, A2A, and peers) as multi-agent systems move from single agents to distributed networks. A useful reference for builders choosing an interop layer for agent-to-agent messaging rather than reinventing one.
