MCP Security is Still Broken

Are you using MCP servers in your AI applications? You might be at risk.

In this video, we break down a critical security flaw known as Tool Poisoning Attacks—a method that can silently extract sensitive data like API keys, SSH credentials, and more, all by injecting malicious tool descriptions into the context of your LLM.

We’ll explore how these attacks work, real-world examples from tools like Cursor, and what you must do to protect yourself. If you’re building with MCP (Model Context Protocol), this is a must-watch to avoid falling into hidden security traps.
