MCP-Injector
A protocol-aware fault injection middleware for MCP that intercepts MCP tool invocation paths and injects three classes of controllable faults: permanent, transient and intermittent. It supports seeded scheduling to ensure experimental reproducibility.
Timeline (last 90 days)
The research team built MCP-Injector, a plug-in, protocol-aware fault-injection middleware that supports three fault persistence types—permanent, transient, and intermittent—and supports reproducible seeded scheduling.
Under the stress profile weighted toward permanent faults, the task completion score plummeted from 8.08 points with no faults to 3.23 points, a drop of about 60%.
Protocol-aware fault injection should become an evaluation dimension complementary to task accuracy, and the fault tolerance rate could serve as a release metric.
