用 AWS Agent Registry 实现运行时动态发现 MCP 工具
Discover tools at runtime with AWS Agent Registry
精选理由
AWS 教你用 Agent Registry 让智能体在运行时语义搜索并动态接入 MCP 工具，工具多了不用再硬编码，写智能体的可以照着做。
当智能体的工具目录从几个扩展到数百个时，硬编码的工具接线会失效。AWS 这篇教程展示了基于 AWS Agent Registry 的 Discover、Instantiate、Execute 三步循环：编排器在运行时通过语义搜索发现 MCP 服务器和 A2A 智能体，而不是在构建期把所有工具编译进去。文中给出了完整的运行时工具发现实现流程。

Discover tools at runtime with AWS Agent Registry
Hardcoded tool wiring breaks down as an agent's catalog grows from a handful of tools to hundreds. This post walks through a runtime Discover, Instantiate, Execute loop built on AWS Agent Registry, where an orchestrator discovers MCP servers and A2A agents through semantic search at runtime instead of compiling every tool at build time.
