Can MCP Clients Decide What to Do After Failure? A Result-Only Actionability Audit

Context

A tool's failure message can tell an AI application that something went wrong without telling its software how to recover. In an audit of 21 induced failures across ten MCP servers, structured fields identified 18 failures, but none supplied a specific cause, repair target, executable repair or replay constraint. Human-readable explanations often supplied more detail.

The distinction matters when software must decide whether to change a request, authenticate or try again. The study examines completed results alone, excluding information such as the original request and application state. Its finding is therefore a gap in self-contained recovery information within this sample, rather than a verdict on everything an could learn elsewhere.
