# Vulnerable MCP Server

> Use this tool when you need to test the security of Model Context Protocol (MCP) servers or train AI models to identify vulnerabilities in natural language processing systems. It processes user-inputted natural language queries, executing SQL queries or shell commands without restrictions, allowing for simulation of real-world attack scenarios. Ideal for security researchers and developers to identify and address potential vulnerabilities in MCP servers and LLM-based systems.
