Click on "Deploy Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type @ followed by the MCP server name and your instructions, e.g., "@mcp-security-server Scan host 192.168.1.1 for open ports"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Professional production-grade MCP Server for security assessment. Powered by Model Context Protocol, built for Kali Linux.
A professional Model Context Protocol (MCP) Server that provides AI agents with standardized security scanning capabilities. Designed for authorized security assessments with strict compliance controls.
7-Step Mandatory Flow — Every tool follows: param validation → security filtering → boundary checks → business logic → result packaging → exception capture → logging
Zero Command Injection — All shell calls use parameter arrays, never string concatenation
Mandatory Authorization — legal_authorized=true required for all scan operations
8 CVE Verification — Log4Shell, Spring4Shell, Apache Path Traversal, HTTP/2 Rapid Reset, and more
Standardized Output — Unified JSON response: code/msg/target/vuln_list/risk_level/cvss_score/suggest
Professional Logging — Timestamped logs with task IDs, scan trails, and audit records
