你好 @alaahong ，
我在阅读 Draft flow 时有几个细化的问题想请教：
1. **Request Router** 在设计中具体承担哪些职责？它是仅做请求分发，还是也会包含负载均衡、错误重试等逻辑？
2. 关于 **Metrics**
- 计划暴露哪些关键指标（例如请求延迟、错误率、缓存命中率、工具调用次数等）？
- 暴露指标是否会让 MCP server 本身变得更“重”？
- 这些指标会暴露给哪些系统？
另外，我之前在调研 fast-excel 时写过一个基于 MCP 的 demo，简单实现了
`list_sheets`、`read_sheet_range`、`cache` 等工具（cache 使用的是 Caffeine 实现）。

Hi @alaahong ,
While reviewing the Draft flow, I had a few detailed questions:
1. For the **Request Router**, what are its specific responsibilities? Will
it only handle request dispatching, or also include load balancing, retries,
and error routing?
2. Regarding **Metrics**
- which key indicators are planned to be exposed (e.g., request latency,
error rate, cache hit ratio, tool invocation counts)?
- Will exposing metrics make the MCP server itself “heavier”?
- To whom will these metrics be exposed?
In addition, when I was exploring fast-excel earlier, I created a small MCP
demo that implements tools like `list_sheets`, `read_sheet_range`, and `cache`
(with Caffeine).
