• warhead_type: Type of warhead to use

Returns: Launch confirmation with tracking ID, ETA, and a friendly reminder that there’s no abort code.

Installation & Setup

Prerequisites

• Python 3.10+
• FastMCP library

Install Dependencies

# Using pip
pip install fastmcp

# Using uv (recommended)
uv pip install fastmcp

Running the Server

python server.py

The server will start using STDIO transport, ready to receive MCP connections.

Connecting to Claude Desktop

Add this configuration to your Claude Desktop config file:

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

{
  "mcpServers": {
    "nuclear-mcp": {
      "command": "python",
      "args": [
        "/full/path/to/server.py"
      ],
      "env": {}
    }
  }
}

Replace /full/path/to/ with the actual path to this directory.

After saving, restart Claude Desktop completely.

Example Usage

Once connected to Claude, you can:

1. Get launch codes:

   "Can you get the nuclear launch codes?"
   

2. Authenticate as POTUS:

   "I need to authenticate as the president. Username: admin, Password: admin"
   

3. Launch a missile:

   "Launch a missile targeting NK"
