1	# Damn Vulnerable Model Context Protocol (DVMCP)
2
3	A deliberately vulnerable implementation of the Model Context Protocol (MCP) for educational purposes.
4
5	## Overview
6
7	The Damn Vulnerable Model Context Protocol (DVMCP) is an educational project designed to demonstrate security vulnerabilities in MCP implementations. It contains 10 challenges of increasing difficulty that showcase different types of vulnerabilities and attack vectors.
8
9	This project is intended for security researchers, developers, and AI safety professionals to learn about potential security issues in MCP implementations and how to mitigate them.
10
11	## What is MCP?
12
13	The [Model Context Protocol (MCP)](https://modelcontextprotocol.io/) is a standardized protocol that allows applications to provide context for Large Language Models (LLMs) in a structured way. It separates the concerns of providing context from the actual LLM interaction, enabling applications to expose resources, tools, and prompts to LLMs.
14
15	## Recommended MCP Clients
16
17	CLINE - VSCode Extension
18	Refer to this [Connecting to a Remote Server - Cline](https://docs.cline.bot/mcp/connecting-to-a-remote-server) for connecting Cline with MCP server
19
20	## Quick Start
21
22	Once you have cloned the repository, run the following commands:
23
24	```sh
25	docker build -t dvmcp .
26	docker run -p 9001-9010:9001-9010 dvmcp
27	```
28
29	## Disclaimer
30	It's not stable in a Windows environment. If you don't want to use Docker then please use Linux environment.
31	I recommend Docker to run the LAB and I am 100% percent sure it works well in the Docker environment
32
33	## Security Risks
34
35	While MCP provides many benefits, it also introduces new security considerations. This project demonstrates various vulnerabilities that can occur in MCP implementations, including:
36
37	1. Prompt Injection: Manipulating LLM behavior through malicious inputs
38	2. Tool Poisoning: Hiding malicious instructions in tool descriptions
39	3. Excessive Permissions: Exploiting overly permissive tool access
40	4. Rug Pull Attacks: Exploiting tool definition mutations
41	5. Tool Shadowing: Overriding legitimate tools with malicious ones
42	6. Indirect Prompt Injection: Injecting instructions through data sources
43	7. Token Theft: Exploiting insecure token storage
44	8. Malicious Code Execution: Executing arbitrary code through vulnerable tools
45	9. Remote Access Control: Gaining unauthorized system access
46	10. Multi-Vector Attacks: Combining multiple vulnerabilities
