A2A Protocol Validator를 사용하여 도메인의 A2A Protocol 지원 확인하기

A2A Protocol 블로그를 바탕으로 A2A Protocol의 기본 개념과 A2A Protocol Python SDK를 사용한 개발 방법을 배웠습니다.
이 글에서는 A2A Protocol Validator를 사용하여 A2A Protocol을 검증하고 AgentCard를 시각화하여 편리한 디버깅을 하는 방법을 소개합니다:
- 주어진 도메인이 A2A Protocol을 지원하는지 확인
- AgentCard 시각화
공개적으로 배포된 A2A Agent의 경우 도메인을 직접 입력하여 검증할 수 있습니다.
로컬에서 실행되는 A2A Agent를 검증하는 방법은?
- Agent 준비
git clone https://github.com/sing1ee/a2a-python-currency.git
cd a2a-python-currency
uv run python main.py
출력:
Installed 27 packages in 33ms
INFO: Started server process [61455]
INFO: Waiting for application startup.
INFO: Application startup complete.
INFO: Uvicorn running on http://localhost:10000 (Press CTRL+C to quit)
이렇게 하면 Currency Agent가 로컬에서 실행되며 포트 10000에서 접근할 수 있습니다.
- 로컬 Agent 서비스 매핑 - Cloudflare Zero Trust 사용 설치는 문서를 참조하세요. 제 환경은 Mac입니다
brew install cloudflared
- Zero Trust 프록시 시작
cloudflared tunnel --url localhost:10000
출력:
+--------------------------------------------------------------------------------------------+
2025-06-03T09:03:02Z INF | Your quick Tunnel has been created! Visit it at (it may take some time to be reachable): |
2025-06-03T09:03:02Z INF | https://sheriff-honor-undefined-relate.trycloudflare.com |
2025-06-03T09:03:02Z INF +--------------------------------------------------------------------------------------------+
https://sheriff-honor-undefined-relate.trycloudflare.com 은 로컬 Agent 서비스에 접근할 수 있는 임시 도메인입니다.
A2A Protocol Validator 열기
A2A Protocol Validator를 열고 위의 도메인을 입력하면 도메인이 A2A Protocol을 지원하는지 확인할 수 있습니다.
이러한 단계를 통해 빠르게 디버깅할 수 있습니다. 향후 A2A 온라인 클라이언트를 출시하여 실행을 더욱 편리하게 만들 예정입니다.

A2A vs ACP Protocol Comparison Analysis Report
A2A (Agent2Agent Protocol) and ACP (Agent Communication Protocol) represent two mainstream technical approaches in AI multi-agent system communication: 'cross-platform interoperability' and 'local/edge autonomy' respectively. A2A, with its powerful cross-vendor interconnection capabilities and rich task collaboration mechanisms, has become the preferred choice for cloud-based and distributed multi-agent scenarios; while ACP, with its low-latency, local-first, cloud-independent characteristics, is suitable for privacy-sensitive, bandwidth-constrained, or edge computing environments. Both protocols have their own focus in protocol design, ecosystem construction, and standardization governance, and are expected to further converge in openness in the future. Developers are advised to choose the most suitable protocol stack based on actual business needs.
