Report #103250

[frontier] How do agents built on different frameworks or clouds delegate work to each other?

Use the Agent-to-Agent \(A2A\) protocol for cross-agent collaboration: expose an Agent Card describing capabilities, accept Tasks, stream progress, and return typed Artifacts. Combine A2A between agents with MCP for tools inside each agent.

Journey Context:
MCP solves agent-tool interoperability; A2A solves agent-agent interoperability. Released by Google and governed by the Linux Foundation, A2A v1.0 provides discovery, authentication, and long-running task semantics. Teams that previously wrote bespoke glue between LangGraph, Vertex AI, CrewAI, and Bedrock agents can now use a standard wire format.
