gaoharimran29-glitch/Cybersecurity-MCP-Server

What is this?

Claude by default has zero native cybersecurity tooling. No WHOIS. No DNS enumeration. No port scanning. No SSL inspection.

This MCP server fixes that — extending Claude with real-world security tools that run live against any domain or IP. Reconnaissance that normally requires multiple specialized tools and 20+ minutes of manual work becomes a single prompt.

This is a local MCP server — it runs entirely on your machine. Your data never leaves your computer. It is also listed on glama mcp registry.

📸 Demo

Single tool — CVE lookup

You: Look up CVEs for apache 2.4.49

Claude: Found 2 critical CVEs for Apache 2.4.49:
        CVE-2021-41773 (Score: 9.8 CRITICAL) — Path traversal vulnerability
        allowing remote code execution if CGI is enabled. Actively exploited
        in the wild...

Full recon

You: Do a complete security recon on reddit.com

Claude: [calls full_recon → runs all core tools in parallel → delivers full analysis]

📋 Prerequisites

• Python 3.12+ — download
• Claude Desktop — download
• Nmap — required for port scanning (download)
• Git — download
• uv - download

⚙️ Installation

Step 1 — Clone the repository

git clone https://github.com/AynOps/AynOps
cd AynOps

Step 2 — Create virtual environment and install dependencies

uv sync

If uv is not installed, install it using:

pip install uv

Step 3 — Install Nmap

Windows:

1. Download from nmap.org/download.html and run the installer
2. Manually add Nmap to PATH:
   • Press Win + S → search "Environment Variables"
   • Under System Variables → find Path → click Edit
   • Click New → add C:\Program Files (x86)\Nmap
   • Click OK on all windows
3. Restart your terminal and verify:

nmap --version

Mac:

brew install nmap

Linux:

sudo apt install nmap

Step 4 — Connect to Claude Desktop

Open your Claude Desktop config file:

OS	Path
Windows	%APPDATA%\Claude\claude_desktop_config.json
Mac	~/Library/Application Support/Claude/claude_desktop_config.json
Linux	~/.config/Claude/claude_desktop_config.json

Add this configuration:

Windows:

{
  "mcpServers": {
    "AynOps": {
      "command": "C:\\full\\path\\to\\AynOps\\.venv\\Scripts\\python.exe",
      "args": ["C:\\full\\path\\to\\AynOps\\server.py"],
      "env": {
        "ABUSEIPDB_API_KEY": "your-api-key-here",
        "IP_API_KEY": "your-api-key-here"
      }
    }
  }
}

Mac/Linux:

{
  "mcpServers": {
    "AynOps": {
      "command": "/full/path/to/AynOps/.venv/bin/python3",
      "args": ["/full/path/to/AynOps/server.py"],
      "env": {
        "ABUSEIPDB_API_KEY": "your-api-key-here",
        "IP_API_KEY": "your-api-key-here"
      }
    }
  }
}

⚠️ Always use the full absolute path to your .venv Python executable — not just python or python3. Claude Desktop may use a different Python installation otherwise.

Note: ABUSEIPDB_API_KEY is only required for the ip_reputation tool. Get a free key at abuseipdb.com. IP_API_KEY is only required for the asn_lookup tool. get a free key at ipapi.com

Step 5 — Restart Claude Desktop

Fully quit and reopen Claude Desktop — closing the window is not enough. Check the system task manager and quit from there.

Verify tools are connected by asking Claude:

What cybersecurity tools do you have available?

Claude should list all tools.

🚀 Usage

Basic tool usage

Do a WHOIS lookup on example.com
Run DNS enumeration on github.com
Scan ports on scanme.nmap.org
Inspect the SSL certificate of stripe.com
Analyze HTTP security headers for github.com
Detect the tech stack of wordpress.org
Look up CVEs for apache 2.4.49
Look up CVEs for log4j 2.14.1
Check the reputation of IP 1.2.3.4
ASN Lookup for google.com
Does example.com have any exposed cloud storage?

Port scan types

Type	Description	Speed
basic	Top 100 ports	Fast (~5s)
service	Service & version detection	Medium (~15s)
os	OS detection (requires admin)	Medium
full	All 65535 ports	Slow (~5min)
vuln	Vulnerability scripts	Slow (~30s)

Scan scanme.nmap.org with service detection

Full recon

For getting best summarized result for the full_recon tool output, please use the prompt threat_analysis ( if your MCP client support ) by following these steps:

Note: Prompt support and automatic prompt chaining vary between MCP clients. Future client updates may improve this workflow.

For Claude Desktop:

1. Start Claude Desktop
2. Click on the + icon
3. Click on connectors
4. If the AynOps is connected, it will show the option for Add from AynOps.
5. Then choose the prompt threat_analysis
6. Claude will use the selected prompt to generate a correlated threat intelligence report.

After this ask this example prompt:

Do a complete security recon on scanme.nmap.org

Claude will run all core tools in parallel and deliver a full security analysis.

Follow-up analysis

Based on the recon, what are the top security risks?
What do the open ports mean from an attacker's perspective?
Is this SSL configuration strong enough for a financial services company?
Cross-reference the open ports with known CVEs for the detected services.

⚠️ Important: LLM Client Behavior

AynOps is an MCP server, which means tool execution is orchestrated by your MCP client (e.g., Claude Desktop, Cursor, VS Code, etc.), not by AynOps itself.

Tool execution may vary

Some LLM clients perform safety checks before invoking MCP tools. As a result, requests such as:

"Run a full security recon on example.com"

may be allowed in one conversation but declined in another, even when using the same server.

This behavior is determined by the LLM client, not by AynOps.

⚠️ Legal & Ethical Usage

Only scan domains and IPs you own or have explicit written permission to scan.

• All tools use public data — safe on any domain
• Port scanning should only target your own infrastructure or authorized systems
• The only public host officially permitted for Nmap testing is scanme.nmap.org
• Unauthorized port scanning may be illegal in your jurisdiction

Intended for:

• Security researchers
• Penetration testers (on authorized targets)
• Developers auditing their own infrastructure
• Students learning cybersecurity concepts
