Agent2Agent (A2A) is an open protocol that allows different
AI Agents to communicate and collaborate with each other, even if they were developed by different providers or use different technologies.
Imagine each
AI agent as a specialized autonomous worker: one manages orders, another responds to customers, and another organizes deliveries. A2A acts as a universal translator that allows them to share information and coordinate actions, regardless of their technical differences.
This protocol, driven by Google and supported by numerous technology companies, makes it easier for
agents to collaborate on complex tasks such as automating business processes, without constant human intervention. A2A aims to create an ecosystem where
agents work together efficiently, regardless of their origin or design, supporting different types of content and tasks of varying complexity.
A2A functions as a complement to the
Model Context Protocol (
MCP): while
MCP connects
AI models with data and tools, A2A focuses on allowing
AI Agents to communicate with each other as autonomous entities, creating a true collaborative ecosystem of artificial intelligences.
