# Vulnerable MCP Server

> Use this tool when you need to simulate and test vulnerabilities in MCP deployments, or to demonstrate common security risks in a controlled environment. It provides a deliberately insecure MCP server for pentesting and training purposes, accepting various inputs and generating outputs that mimic real-world vulnerability scenarios. Ideal for security professionals and researchers looking to identify and exploit weaknesses in MCP configurations.
