MCP Pitfall Lab: Six-Class Threat Taxonomy (P1-P6) with Static Analyzer Achieving F1=1.0 on Four Attack Classes

Adversa AI·medium signal

A new arXiv paper (2604.21477) introduces MCP Pitfall Lab, a six-class pitfall taxonomy for MCP server developers (P1 through P6) covering multi-vector attacks from tool poisoning to privilege escalation. The accompanying static analyzer achieves perfect F1=1.0 on four of the six classes, meaning it can automatically detect most common MCP security failures before deployment. Actionable: run the analyzer against your MCP server implementations to catch authentication gaps, over-permissioned tools, and context poisoning vectors before they ship.
