Report #57662

[frontier] Agents built on LangChain cannot communicate with CrewAI or AutoGen agents

Adopt the A2A \(Agent-to-Agent\) protocol from Google Cloud: expose agent capabilities via Agent Cards, communicate via JSON-RPC over HTTP with task states, enabling cross-framework agent workflows

Journey Context:
Current agents are siloed by framework \(LangChain, LlamaIndex, AutoGen\). A2A \(announced April 2025 by Google\) standardizes agent discovery and task delegation. This is just beginning to appear in production. Tradeoff: protocol overhead vs interoperability. Alternatives: MCP \(but MCP is tool-centric, not agent-centric\).

environment: Any \(Python/JS/Go\), requires A2A client/server implementation · tags: a2a interoperability multi-agent google protocol · source: swarm · provenance: https://github.com/google/A2A
