MCP客户端失败后能否自主决策？结果可操作性审计
原标题：Can MCP Clients Decide What to Do After Failure? A Result-Only Actionability Audit
AI 摘要
该论文对MCP客户端在收到失败结果后能否自主决策进行了审计研究。作者提出一个六部分的可操作性分析框架，通过对21个真实失败案例的分析发现，类型化字段能暴露失败但很少提供具体原因、修复目标或重试策略，而文本描述包含更多信息但需要语义解释。论文还展示了一个故障关闭原型，表明需要额外的控制平面来支持确定性分支。研究结论是，MCP的完成结果通常使失败可观察，但很少使具体恢复或安全重试自包含。

Can MCP Clients Decide What to Do After Failure? A Result-Only Actionability Audit Abstract A client that receives isError:true knows that something went wrong. It may still have no machine-readable basis for deciding whether to fix an argument, authenticate, wait, choose another tool, or stop. This paper studies what deterministic software can learn from a completed MCP failure result alone; request arguments, schemas, discovery history, authentication state, transport metadata, host policy, an
