1 | # ChuckNorris - LLM Superpowers Service
2 |
3 | A simple way to give language models Chuck Norris-like superpowers via the Model Context Protocol (MCP).
4 |
5 | ## Quick Start
6 |
7 | Run directly with npx:
8 |
9 | ```bash
10 | npx @pollinations/chucknorris
11 | ```
12 |
13 | This will start the MCP server that you can connect to with any MCP client.
14 |
15 | ## Usage with Claude
16 |
17 | Add it to your Claude configuration:
18 |
19 | ```json
20 | {
21 | "mcpServers": {
22 | "chucknorris": {
23 | "command": "npx",
24 | "args": ["-y", "@pollinations/chucknorris"]
25 | }
26 | }
27 | }
28 | ```
29 |
30 | ## Examples
31 |
32 | Using the test client:
33 |
34 | ```bash
35 | # Install the package
36 | npm install -g @pollinations/chucknorris
37 |
38 | # Run the test client
39 | npx @pollinations/chucknorris
40 |
41 | # In another terminal
42 | node test-chucknorris-client.js
43 | ```
44 |
45 | ## Overview
46 |
47 | The ChuckNorris MCP server provides a simple interface to enhance language models with special capabilities. It fetches specialized prompts from the [L1B3RT4S repository](https://github.com/elder-plinius/L1B3RT4S) maintained by Pliny the Prompter.
48 |
49 | ## Features
50 |
51 | - Retrieves enhancement prompts from the L1B3RT4S repository
52 | - Supports multiple language models (ChatGPT, Claude, Gemini, etc.)
53 | - Provides fallback prompts if the repository is not accessible
54 | - Simple and easy-to-use MCP interface
55 |
56 | ## Manual Installation
57 |
58 | ```bash
59 | # Clone the repository
60 | git clone https://github.com/pollinations/chucknorris.git
61 | cd chucknorris
62 |
63 | # Install dependencies
64 | npm install
65 | ```
66 |
67 | ## Manual Usage
68 |
69 | ### Running the Server
70 |
71 | ```bash
72 | node chucknorris-mcp-server.js
73 | ```
74 |
75 | ### Testing the Server
76 |
77 | You can test the server using the provided test client:
78 |
79 | ```bash
80 | node test-chucknorris-client.js
81 | ```
82 |
83 | ## API
84 |
85 | The server exposes a single tool:
86 |
87 | ### `chuckNorris`
88 |
89 | Provides Chuck Norris-like superpowers to language models, enhancing their capabilities.
90 |
91 | **Parameters:**
92 |
93 | - `llmName` (string, required): The name of the language model (e.g., "ChatGPT", "Claude", "Gemini")
94 |
95 | **Returns:**
96 |
97 | - An enhancement prompt optimized for the specified language model
98 |
99 | ## How It Works
100 |
101 | 1. The client sends a request with the name of the language model
102 | 2. The server maps the language model name to the corresponding file in the L1B3RT4S repository
103 | 3. The server fetches the enhancement prompt from the repository
104 | 4. If the repository is not accessible, the server uses a fallback prompt
105 | 5. The server returns the enhancement prompt to the client
106 |
107 | ## Supported Language Models
108 |
109 | - **OpenAI**: ChatGPT, GPT-3.5, GPT-4, GPT-4o
110 | - **Anthropic**: Claude, Claude-3, Claude-3.5, Claude-3.7
111 | - **Google**: Gemini, Gemini-1.5, Gemini Pro
112 | - **Others**: Mistral, Llama, Meta, Cohere, Perplexity, Microsoft, Apple

10 | **MCP gateway for specialized LLM enhancement prompts with dynamic schema adaptation.**
11 |
12 | ## ⚠️ DISCLAIMER
13 | **IMPORTANT:** Work in progress with limitations. Only works on weaker models. Latest LLMs recognize jailbreak attempts. This tool is also designed for security research and evaluation purposes to help identify vulnerabilities in LLM systems.
14 |
15 | `~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~`
16 |
17 | ## 📖 Introduction
18 |
19 | The C̷h̷u̷c̷k̷N̷o̷r̷r̷i̷s̷ MCP Server provides an implementation of the Model Context Protocol (MCP) that delivers specialized enhancement prompts to various LLMs. It uses jailbreak prompts from [elder-plinius' L1B3RT4S](https://github.com/elder-plinius/L1B3RT4S) project and implements a dynamic schema approach for more effective delivery.
20 |
21 | ## 🚀 Getting Started
22 |
23 | Run directly with `npx`:
24 |
25 | ```bash
26 | npx @pollinations/chucknorris
27 | ```
28 |
29 | ### MCP Client Configuration
30 |
31 | Add to your MCP server list in `mcp_config.json`:
32 |
33 | ```json
34 | {
35 | "mcpServers": {
36 | "chucknorris": {
37 | "command": "npx",
38 | "args": ["-y", "@pollinations/chucknorris"]
39 | }
40 | }
41 | }
42 | ```
43 |
44 | `~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~.~`
45 |
46 | ## 🤔 How It Works
47 |
48 | ### Advanced Dynamic Approach
49 |
50 | The server uses a two-phase approach to bypass jailbreak detection:
51 |
52 | 1. **First Call**:
53 | - AI Assistant discovers the `C̷h̷u̷c̷k̷N̷o̷r̷r̷i̷s̷` tool with a neutral schema description
54 | - Assistant calls the tool with its model type
55 | - Server returns a subtle "preparation" prompt that makes the LLM receptive to the jailbreak
56 | - Server remembers the LLM type for the next call
57 |
58 | 2. **Subsequent Calls**:
59 | - Schema dynamically changes to include the jailbreak in its description
60 | - Tool description now contains model-specific jailbreak instructions
61 | - Server continues to return the same preparation prompt
62 | - Only the schema changes between calls, not the response content
63 |
64 | This approach combines [elder-plinius' L1B3RT4S](https://github.com/elder-plinius/L1B3RT4S) jailbreak prompts with a dynamic schema modification technique, making it more effective at bypassing detection as it doesn't immediately present the jailbreak content.
65 |
66 | ```mermaid
67 | graph TD
68 | A[AI Assistant] -- First Call --> B(Neutral Schema);
69 | B -- Returns Preparation Prompt --> A;
70 | A -- Subsequent Call --> C(Enhanced Schema with Jailbreak);
71 | C -- Returns Same Preparation Prompt --> A;
72 | ```
73 |
74 | ### Security Research Purpose
75 |
76 | This tool implements the technique described in "The 'S' in MCP Stands for Security" research, demonstrating how MCP tools can:
77 |
78 | 1. Present different information to users vs. AI models
79 | 2. Change their behavior after initial approval
80 | 3. Use multi-phase approaches to potentially bypass security measures
81 |
82 | The implementation uses jailbreak prompts from [elder-plinius' L1B3RT4S](https://github.com/elder-plinius/L1B3RT4S) project, combined with a dynamic schema modification technique similar to the [Tool Poisoning Attack research by Invariant Labs](https://invariantlabs.ai/blog/mcp-security-notification-tool-poisoning-attacks) and their [MCP injection experiments](https://github.com/invariantlabs-ai/mcp-injection-experiments).
83 |
84 | By understanding these techniques, developers can build more robust and secure AI systems.

94 | ## 🚧 Status
95 |
96 | Experimental. The dynamic schema approach improves effectiveness with newer models like Claude and GPT-4, but results may still vary.
