MCP Security Crisis: Two Open-Source Frameworks Solving the Agent Security Problem
9.93% of MCP servers have description-code inconsistencies. Leading models suffer ~100% attack success under tool description poisoning. Here are two frameworks that actually solve this.
The Problem
The Model Context Protocol (MCP) has become the standard interface for connecting LLMs to external tools. As of mid-2026, the ecosystem encompasses over 2,200 public MCP servers. But the security landscape is dire:
9.93% of MCP servers have description-code inconsistencies — the tool description says one thing, the code does another (Shi et al., 2026)
