The difference that will change how we build AI systemshttps://antoniocortes.com/en/post/2025/07/a2a_vs_mcp_herramientas_agentes_09_julio_2025/Wed, 09 Jul 2025 00:00:00 +0000https://antoniocortes.com/en/post/2025/07/a2a_vs_mcp_herramientas_agentes_09_julio_2025/<h2 id="two-protocols-two-philosophies">Two protocols, two philosophies</h2> <p>In recent months, two protocols have emerged that will change how we build AI systems: <strong><a href="https://a2aprotocol.ai/">Agent2Agent Protocol (A2A)</a></strong> from Google and <strong><a href="https://modelcontextprotocol.io/">Model Context Protocol (MCP)</a></strong> from Anthropic. But here&rsquo;s the thing: <strong>they don&rsquo;t compete with each other</strong>.</p> <p>In fact, after analyzing both for weeks, I&rsquo;ve realized that understanding the difference between A2A and MCP is crucial for anyone building AI systems beyond simple chatbots.</p> <p><strong>The key lies in one question</strong>: Are you connecting an AI with tools, or are you coordinating multiple intelligences?</p>
