Agent to Agent Protocol

What’s the difference between MCP and A2A?

MCP (Model Context Protocol) and A2A (Agent-to-Agent Protocol) serve different purposes and work in distinct ways.


🧩 MCP (Model Context Protocol)Purpose: Enables a single AI model to interact with external tools and data sources • How it works: Uses precise, structured function calls to connect with APIs and tools • Best for: Predictable, well-defined tasks like data retrieval, calculations, or search


🤖 A2A (Agent-to-Agent Protocol)Purpose: Allows multiple AI agents to collaborate asynchronously by sharing tasks and outputs • How it works: Supports flexible task delegation and coordination in multi-agent environments • Best for: Complex workflows where autonomous agents need to solve problems together


SummaryMCP: Enhances individual agent capabilities • A2A: Enables collaboration between multiple agents
