English(EN) Put a deadline on an MCP tool's downstream request

Node.js示例为MCP工具添加请求截止日期

本文提供了一个Node.js示例,用于在MCP工具中为下游请求实现截止日期。它演示了如何使用`AbortController`和`setTimeout`来确保对外部服务的请求不会无限期地保持打开状态,即使响应体到达缓慢。辅助函数`readToolJson`旨在通过拒绝请求并返回适当的工具错误来处理各种失败情况,包括非成功的HTTP响应、无效的JSON和停滞的读取。作者强调,这种本地截止日期机制与更广泛的MCP取消策略不同,也不能保证远程服务已停止处理请求。 AI

影响 通过防止对下游服务的无限期等待来提高AI工具的可靠性。

    为MCP工具的下游请求设置截止日期

    <p>An MCP tool can stay responsive at its public endpoint while a downstream service keeps its requests open. Adding another container does not tell a waiting request when to stop. Give each downstream read an explicit deadline. Decide upfront how the tool reports the failure.</p…
