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
