# A2A Protocol

> A standardized open protocol enabling seamless communication and collaboration between AI agents across different platforms and frameworks.

The A2A Protocol is Google's Agent2Agent communication standard that solves interoperability challenges in the AI ecosystem. It allows specialized AI agents to work together regardless of their underlying implementation, supporting everything from quick tasks to long-running research with real-time feedback.
