Model Context Protocol (MCP) standardizes how models and agents access external tools and resources. Agent2Agent (A2A) Protocol defines how agents running on diverse frameworks and platforms communicate. Together, MCP and A2A enable collaborative agent ecosystems with seamless interoperability.

In this session, we’ll unpack both protocols, show how they complement each other. We’ll then see demos on how to implement these protocols in agent frameworks such as Agent Development Kit (ADK) and deploy them to the cloud to give you practical knowledge to start building your own interoperable agents.
