A Taxonomy of Runtime Faults in Model Context Protocol Servers
Researchers have created the first empirical taxonomy of runtime faults in Model Context Protocol (MCP) servers, identifying 73 distinct fault types across 11 categories after analyzing 837 fault threads from 473 GitHub repositories. The study reveals that configuration parameters accepted but not enforced at runtime cause widespread reliability issues in LLM tool-augmentation workflows, with developer surveys confirming that these faults are commonly experienced across the industry.
