Unicode Steganography Puzzles MCP server

Unicode Puzzles MCP is a powerful tool for creating and managing encoded messages using zero-width characters and advanced Unicode techniques. It provides quantum-themed puzzle templates that leverage steganography principles to hide secret messages within seemingly normal text.

Installation

To install the Unicode Puzzles MCP package, run the following command in your terminal:

npm install unicode-puzzles-mcp

Basic Usage

After installing the package, you can import and initialize the MCP server in your JavaScript application:

import { UnicodePuzzlesMCP } from 'unicode-puzzles-mcp';

// Initialize MCP server
const mcp = new UnicodePuzzlesMCP();

Creating Puzzles

You can create different types of encoded puzzles using the available templates:

// Create a quantum puzzle
const puzzle = await mcp.createPuzzle({
  template: 'quantum',
  message: 'System integrity compromised',
  secret: 'LIBRAXIS://repair-protocol-7A'
});

Available Templates

Unicode Puzzles MCP offers several themed templates for your encoded messages:

• Quantum - Messages encoded using quantum superposition principles
• Orbital - Circular pattern encoding using orbital mechanics
• Glitch - Random noise patterns with hidden data
• Void - Space-based encoding using astronomical symbols

Advanced Puzzle Creation

You can customize your puzzles with different difficulty levels:

const quantumPuzzle = await mcp.createPuzzle({
  template: 'quantum',
  message: 'Reality distortion detected',
  secret: 'Coordinates: α-359-ω',
  difficulty: 'advanced'
});

// Result: 【𝚀𝚄𝙰𝙽𝚃𝚄𝙼】∎∎∎Reality⠀distortion⠀detected∎∎∎
// (with hidden ZWSP characters encoding the secret)

Decoding Puzzles

To decode a puzzle and extract the hidden message:

// Decode an encoded message
const decoded = await mcp.decodePuzzle(encodedText);

The decoded result will contain both the visible message and the hidden secret that was encoded using zero-width characters and other Unicode steganography techniques.

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "unicode-puzzles" '{"command":"node","args":["/path/to/unicode-puzzles-mcp/src/server/index.js"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "unicode-puzzles": {
            "command": "node",
            "args": [
                "/path/to/unicode-puzzles-mcp/src/server/index.js"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "unicode-puzzles": {
            "command": "node",
            "args": [
                "/path/to/unicode-puzzles-mcp/src/server/index.js"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
