MCP Gave AI Agents Tools. A2A Gives Them Coworkers.
The Model Context Protocol (MCP) enables AI agents to interact with tools and external data sources, while the Agent2Agent (A2A) protocol facilitates collaboration between multiple agents. A2A introduces concepts like Agent Cards for discovery, standardized communication, and task lifecycle management, moving beyond simple prompt chaining for complex workflows. This allows agents to function more like discoverable services, enabling sophisticated multi-agent systems for tasks ranging from software development to customer support. AI
IMPACT Enables more complex, multi-agent AI workflows by providing a standardized communication and discovery layer.
