Story

The MCP security tooling ecosystem has matured rapidly:

  1. Adversa AI MCP Security TOP 25 — Most comprehensive vulnerability taxonomy (injection, confused deputy, credential theft, tool name spoofing, schema poisoning) adversa.ai
  2. Vulnerable MCP Project — CVE database tracking critical MCP vulnerabilities including CVE-2026-25536 (TypeScript SDK cross-client data leak), CVE-2026-23744 (MCPJam inspector RCE), and chained mcp-server-git CVEs vulnerablemcp.info
  3. MCPHammer — First open-source security testing framework from Praetorian
  4. CoSAI MCP Security Guide — 12 threat categories from the Coalition for Secure AI
  5. Cisco MCP Catalog + AI BOM — First enterprise vendor tooling

This represents category maturation from "MCP has security problems" to "here are the tools to fix them."
