A2A Coordination Semantics: HCT for Google's Agent Protocol

December 18, 2025
I recently announced the Model Context Protocol (MCP) adaptation of Harmonic Coordination Theory (HCT). Today, I'm expanding the ecosystem to support Google's Agent-to-Agent (A2A) Protocol. While MCP focuses on the standardized client-host connection, A2A is designed for decentralized, multi-agent c…

Model Context Protocol (MCP) is becoming the standard for connecting AI agents to tools and resources. It's elegant, well-designed, and solves a real problem: how do agents discover and use external capabilities? But there's something missing. MCP tells agents what tools exist. It doesn't tell them …

Your multi-agent system is failing. But how do you describe what's wrong? "The agents are... not working together" doesn't help your debugging session. You need a diagnostic vocabulary—precise terms that map symptoms to root causes to solutions. The Problem with Ad-Hoc Diagnosis Most teams describe …
