MCP vs A2A Protocol: Which AI Standard Will Win in 2026?
The Rietaviškis project architecture document references both MCP (Model Context Protocol) and A2A Protocol v1.2. These are the two competing standards for how AI agents communicate with each other and with external tools.
Here is the key difference:
MCP (by Anthropic) is a client-server protocol for connecting AI models to data sources and tools. It is already supported by Claude, Cursor, and Wix. A2A (Agent-to-Agent, by Google) is a peer-to-peer protocol for autonomous agent communication — agents that can delegate tasks to other agents without human intervention.
For a city-scale learning platform like Rietaviškis, the choice matters enormously. MCP gives you structured tool access. A2A gives you autonomous agent orchestration.
In 2026, the question is not which one is better — it is which one your stack supports.
💬 Are you building with MCP today? Have you experimented with A2A? What is your current AI agent stack?
