ChineseAI Agent Protocols & Standards
AI Agent 协议与标准
Overview
概述
This skill covers the emerging ecosystem of open standards and protocols for AI agents. These specifications define how agents discover capabilities, communicate with each other, make payments, render UI, and are described declaratively.
本技能涵盖AI Agent领域新兴的开放标准与协议生态。这些规范定义了Agent如何发现能力、彼此通信、进行支付、渲染UI以及以声明式方式被描述。

└─────────────────────────────────────────────┘Choosing the Right Protocol
选择合适的协议
- Building tools for agents to call? Use MCP to expose them as tool servers.
- Packaging reusable knowledge/instructions? Use Agent Skills (SKILL.md).
- Orchestrating multiple agents? Use A2A for inter-agent communication (ACP's REST approach merged into A2A).
- Monetizing an API for agent consumption? Use x402 for micropayments.
- Enabling agent-driven purchases? Use AP2 for secure commerce flows.
- Defining agent configurations declaratively? Use ADL for portable blueprints.
- Guiding coding agents in a repo? Add an AGENTS.md file.
- Serving rich UI from an MCP server? Use MCP Apps.
- Running multi-agent systems locally? Use Docker cagent.
- 为Agent构建可调用的工具？ 使用MCP将其作为工具服务器暴露。
- 打包可复用的知识/指令？ 使用Agent Skills（SKILL.md）。
- 编排多个Agent？ 使用A2A进行Agent间通信（ACP的REST方案已合并至A2A）。
- 将API monetize供Agent使用？ 使用x402进行微支付。
- 实现由Agent驱动的采购？ 使用AP2实现安全商务流程。
- 以声明式方式定义Agent配置？ 使用ADL创建可移植的蓝图。
- 在代码库中指导编码Agent？ 添加AGENTS.md文件。
- 从MCP服务器提供富交互UI？ 使用MCP Apps。
- 在本地运行多Agent系统？ 使用Docker cagent。
