Report #84109

[frontier] Multi-agent systems built on MCP cannot negotiate task delegation or context sharing between autonomous agents from different vendors

Adopt the A2A \(Agent2Agent\) protocol to expose AgentCards \(capability advertisements\) and implement task/update streaming between heterogeneous agents, enabling cross-platform handoffs

Journey Context:
MCP excels at tool-calling but assumes a client-server hierarchy. A2A treats every agent as a peer that can discover and delegate to others. By standardizing Task objects and streaming updates via SSE, A2A allows a LangGraph agent to delegate a subtask to a CrewAI agent without tight coupling. This is crucial for enterprise multi-vendor agent mesh architectures.
