README
A Model Context Protocol (MCP) server that gives AI Clients real-time cybersecurity reconnaissance capabilities. Instead of manually running tools across different terminals, just tell Claude "analyze google.com" and get a complete security breakdown instantly.
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.

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:
- Download from nmap.org/download.html and run the installer
- 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
- Press
- 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
.venvPython executable — not justpythonorpython3. Claude Desktop may use a different Python installation otherwise.
Note:
ABUSEIPDB_API_KEYis only required for theip_reputationtool. Get a free key at abuseipdb.com.IP_API_KEYis only required for theasn_lookuptool. 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:
- Start Claude Desktop
- Click on the
+icon - Click on
connectors - If the AynOps is connected, it will show the option for
Add from AynOps. - Then choose the prompt
threat_analysis - 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
