@wavaai.feeds: MCP (Model Context Protocol) and A2A (Agent-to-Agent Protocol) are both agent protocols but operate at different layers. MCP focuses on giving a single LLM access to external tools. The model manages everything: it receives your query, decides which tools to call, gets the results back through an MCP Client, and then creates the final response. The MCP Servers are just wrappers around APIs like flight booking or Google Calendar — one central brain. A2A, on the other hand, handles coordination between multiple autonomous agents. Instead of one single model, an Orchestrator Agent delegates tasks to specialized agents, each with its own tools, memory, and reasoning loop. The Orchestrator never directly interacts with APIs like Flight. It talks to a dedicated Flight Agent that handles that domain independently. This difference matters when building systems: - MCP works well when one model can handle the entire task with tool access. - A2A is needed for complex subtasks or when parallel operation without bottlenecks is desired. Same task — like booking a flight and adding it to your calendar — could be handled centrally or distributed across agents depending on the architecture. Understanding where this boundary lies will influence your design choices in 2026.
