🚀 Quick Start

1. Install Dependencies

pip install -r requirements.txt

2. Configure Claude Desktop

Edit your Claude Desktop config file:

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

{
  "mcpServers": {
    "Hashcat-MCP": {
      "command": "python",
      "args": [
        "C:\\path\\to\\your\\hashcat_mcp_server.py"
      ],
      "env": {
        "HASHCAT_PATH": "C:\\path\\to\\hashcat\\hashcat.exe",
        "HASHCAT_SAFE_DIRS": "C:\\wordlists"
      }
    }
  }
}

Important: Update the paths to match your system:

• args[0] - Path to your hashcat_mcp_server.py file
• HASHCAT_PATH - Path to your hashcat executable
• HASHCAT_SAFE_DIRS - Comma-separated list of safe directories for wordlists

3. Restart Claude Desktop

Close and reopen Claude Desktop to load the MCP server.
