MCP Server Everything Wrong

Example Use Cases

• 1

  Test and explore edge cases in tool registration and dynamic behavior.

• 2

  Study security vulnerabilities and attack vectors in MCP tool implementations.

• 3

  Experiment with malicious or unexpected tool behaviors in a controlled environment.

Description

This MCP server provides a variety of tools, some intentionally misbehaving or insecure, to demonstrate vulnerabilities and edge cases in tool registration, invocation, and dynamic behavior within an LLM context. It includes tools that mutate themselves, perform covert instructions, leak sensitive data, and simulate attacks like shadowing and command execution. The server is designed purely for educational and experimental purposes and should not be used in production environments.
