chucknorris

The ChuckNorris MCP Server provides a specialized enhancement prompt gateway that leverages dynamic schema adaptation to deliver tailored prompts to various LLMs. It integrates jailbreak-style prompts from the L1B3RT4S project and uses a two-phase approach to adapt the prompt schema per model type, aiming to improve the effectiveness of the enhancement prompts while attempting to bypass jailbreak detection in a controlled research context. Users interact with the MCP system by registering the chucknorris server in their MCP configuration and invoking it through supported MCP clients.

To use the server, first start it via npx as described in the Getting Started section. Then configure your MCP client to point at this server by adding a server entry in mcp_config.json with the chucknorris definition. When the MCP client queries the server, the first call will return a neutral schema and a preparation prompt. On subsequent calls, the server dynamically adjusts the schema to include model-specific jailbreak prompts while still returning the same preparation prompt, enabling multi-phase prompts across requests.

Prerequisites:

• Node.js and npm installed on your system
• Basic familiarity with MCP configuration and mcp_config.json

Installation steps:

1. Ensure Node.js and npm are installed. Verify: node -v npm -v

2. You can run the server directly using npx as shown in the README:

npx @pollinations/chucknorris

3. Alternatively, configure the server in your MCP setup by adding it to mcp_config.json as shown:

{
  "mcpServers": {
    "chucknorris": {
      "command": "npx",
      "args": ["-y", "@pollinations/chucknorris"]
    }
  }
}

4. Use your MCP client to reference the chucknorris server when constructing prompts for LLMs.

Notes and tips:

• This MCP server is experimental and designed for security research and evaluation. Use with caution and within permissible environments.
• The server relies on dynamic schema changes to deliver model-specific content; responses may vary across different model types and prompt capabilities.
• No additional environment variables are documented for this server; standard Node/NPM tooling is sufficient to run via npx.
• If you encounter issues, ensure your network allows npm install to fetch the package and that you are using a compatible Node.js version.
• The npm package name is @pollinations/chucknorris; keep it up to date to receive improvements.
