Cross-Org Agent Protocol — 跨组织多智能体协调协议：多委托人、联邦编排、工作区委托

1. 解决的问题

MCP（Model Context Protocol）：解决 Agent 与工具/数据源的连接（Host ↔ Server）

2. 核心算法逻辑

现有 MAS 协议栈有两个标准：

3. 业务应用场景

业务背景：母婴品牌与代工工厂建立"智能协同"关系——品牌的采购 Agent 需要直接与工厂的产能规划 Agent 协作，实时获取产能数据、协商交期。但两方 Agent 系统分属不同公司，各有利益。

业务背景：品牌在 Amazon、TikTok、独立站三个平台各有独立 Agent 系统（不同供应商提供）。大促期间需要三个系统协同调配预算，但三方 Agent 来自不同厂商，无共同 API。
