Model Context Protocol Vs Agent2Agent: Practical Integration with Enterprise Data

Model Context Protocol (MCP), introduced by Anthropic in November 2024, and Agent2Agent (A2A), launched by Google in April 2025, are two different ways of designing AI systems that allow language models and agents to work with tools or with each other.

While both aim to make AI development faster and more efficient, they solve different problems. MCP focuses on deterministic tool integration for language models, meaning it provides predictable ways for models to interact with external tools. A2A, on the other hand, focuses on asynchronous agent-to-agent communication, allowing multiple agents to coordinate and share information independently.
