🔧 Configuration

MCP Inspector (Development)

# Install and run with MCP Inspector
npx @modelcontextprotocol/inspector nikto-mcp@latest

MCP Client Configuration

Add to your MCP client configuration:

{
  "mcpServers": {
    "nikto": {
      "command": "node",
      "args": ["/absolute/path/to/nikto-mcp/index.js"],
      "env": {
        "NIKTO_BINARY": "/usr/local/bin/nikto",
        "LOG_LEVEL": "info"
      }
    }
  }
}

Testing with MCP Inspector (Dev)

# Install MCP Inspector
npm install -g @modelcontextprotocol/inspector

# Test the server
npx @modelcontextprotocol/inspector node index.js

Environment Variables

• NIKTO_MODE - Execution mode: local or docker (default: local)
• NIKTO_DOCKER_IMAGE - Docker image to use (default: ghcr.io/sullo/nikto:latest)
• NIKTO_DOCKER_NETWORK - Docker network mode (default: host)
• NIKTO_BINARY - Path to Nikto executable for local mode (default: nikto)
• LOG_LEVEL - Logging level: debug, info, warn, error (default: info)
• MCP_STDOUT_LOGS - Allow info/debug logs to stdout: allow or unset (default: discarded for MCP compatibility)
• SCAN_TIMEOUT - Maximum scan duration in seconds (default: 3600)
• MAX_CONCURRENT_SCANS - Maximum concurrent scans (default: 3)

Note: JSON output automatically uses unique filenames per scan (/tmp/nikto-scan-<uuid>.json) to prevent concurrent scan collisions.

🐳 Docker Support

The MCP server supports running Nikto via Docker for better isolation and consistency.

Docker Mode Configuration
