A2A Protocol
定义
The Agent-to-Agent (A2A) protocol is an open standard for inter-agent communication that allows AI agents built on different platforms to discover each other, negotiate capabilities, delegate tasks, and share results. A2A enables a multi-vendor agent ecosystem where a JieGou workflow can delegate a sub-task to an external agent and receive structured results back.
A2A vs. MCP
MCP (Model Context Protocol) connects agents to tools and data sources. A2A connects agents to other agents. They are complementary: MCP gives agents hands (tools to act), A2A gives agents colleagues (other agents to collaborate with). JieGou supports both protocols.
