🌐 Overview

Modern Large Language Models (LLMs) operate in sandboxed, non-deterministic execution environments devoid of native raw-socket access, packet crafting abilities, and live network reconnaissance primitives. When tasked with auditing an attack surface, AI agents are fundamentally constrained by static training cutoff boundaries and an inability to query live network interfaces.

AynOps bridges this operational divide. Built on top of the Model Context Protocol (MCP) specification using the FastMCP framework, AynOps exposes an extensible suite of deterministic cybersecurity reconnaissance tools directly to LLM agents (such as Cursor, VS Code, Claude Desktop, and custom MCP clients) over a standard JSON-RPC 2.0 stdio transport.

Full Reconnaissance Pipeline — Parallelized Security Assessment

Trigger the 3-wave parallel execution engine to synthesize network perimeter state, DNS resource records, SSL/TLS posture, email anti-spoofing enforcement, HTTP headers, and software stack fingerprints into a single structured report:

📋 Prerequisites

Ensure your host environment meets the following runtime requirements before starting the server:

• Python Runtime: Python >= 3.12 (Download Python)
• Network Scanner: Nmap binary installed and accessible in the system PATH (Download Nmap)
• Environment & Package Manager: uv (Recommended for high-performance virtual environments, Install uv) or pip
• Version Control: Git (Download Git)
• MCP Client: Cursor, VS Code (MCP extension), Claude Desktop, Continue.dev, Zed, or any client implementing the MCP JSON-RPC protocol.
• Container Runtime (Optional): Docker Engine / Docker Desktop (Download Docker)

⚙️ Installation

Method 1: Local Virtual Environment Setup (Recommended)

Step 1: Clone the Repository

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

Step 2: Provision Virtual Environment and Install Dependencies

Using uv (Fastest):

uv sync

Alternatively, using standard Python tooling:

python -m venv .venv

# On Linux/macOS:
source .venv/bin/activate

# On Windows (PowerShell):
.venv\Scripts\Activate.ps1

pip install -e .

Step 3: Install and Configure Nmap

Nmap must be installed locally and registered in your system PATH for the port_scan tool:

brew install nmap
nmap --version

# Debian / Ubuntu / Kali
sudo apt update && sudo apt install -y nmap

# Fedora / RHEL
sudo dnf install -y nmap

# Arch Linux
sudo pacman -S nmap

Step 4: Configure Your MCP Client

Locate and edit your client's MCP configuration file (e.g., Claude Desktop, Cursor, or VS Code):

Insert the AynOps server stanza:

Windows (claude_desktop_config.json):

{
  "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-abuseipdb-api-key-here",
        "HIBP_API_KEY": "your-hibp-api-key-here"
      }
    }
  }
}

macOS / Linux (claude_desktop_config.json):

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

[!IMPORTANT] Always supply the absolute filesystem path to your .venv Python binary and server.py file to prevent the client from binding to a mismatched global Python runtime.

[!NOTE] ABUSEIPDB_API_KEY is optional and only required for ip_reputation (Obtain free at abuseipdb.com). HIBP_API_KEY is optional and only required for hibp_check (Obtain at haveibeenpwned.com/API/Key). All other tools operate with zero API keys.

Step 5: Launch Client and Validate Registration

1. Terminate all running client processes completely (ensure no background instances remain in Task Manager / Activity Monitor).
2. Re-open your MCP client.
3. Verify tool availability by querying:

   What cybersecurity tools do you have available?
   

Method 2: Containerized Deployment via Docker

AynOps ships a production-ready Dockerfile bundling Python 3.12, uv, and nmap, eliminating host dependency requirements.

Step 1: Build the Image

git clone https://github.com/AynOps/AynOps.git
cd AynOps
docker build -t aynops:latest .

Step 2: Verify Stdio Transport

Run a one-shot container execution. The container will initialize and listen for MCP JSON-RPC messages on stdin:

docker run --rm -i aynops:latest
# Press Ctrl+C to exit

Step 3: Configure Client for Docker Execution

Configure your client to spawn the container directly:

{
  "mcpServers": {
    "AynOps": {
      "command": "docker",
      "args": [
        "run",
        "--rm",
        "-i",
        "-e", "ABUSEIPDB_API_KEY=your-abuseipdb-api-key-here",
        "-e", "HIBP_API_KEY=your-hibp-api-key-here",
        "aynops:latest"
      ]
    }
  }
}

[!TIP] The container must run in interactive mode (-i) without detached flags (-d) to preserve the standard I/O communication pipe required by the MCP protocol.

🚀 Usage

Natural Language Tool Invocations

Once connected, you can interact with individual reconnaissance tools or prompt compound analytical queries:

# Domain & DNS Reconnaissance
"Perform a WHOIS query on target-organization.com"
"Enumerate all DNS resource records and brute-force common subdomains for example.com"
"Query Certificate Transparency logs for *.internal.corp.com"

# Network & Host Fingerprinting
"Run a service version port scan on scanme.nmap.org"
"Execute an ASN lookup for IP 1.1.1.1 and identify the BGP prefix"
"Analyze the IP reputation of 198.51.100.42"

# Web Application & Perimeter Security
"Inspect the SSL/TLS certificate of payment.gateway.io on port 443"
"Audit the HTTP security headers of enterprise-app.com and report misconfigurations"
"Fingerprint the CMS, JavaScript frameworks, and CDNs running on target.com"
"Trace the HTTP redirect chain for http://insecure-portal.com"
"Inspect robots.txt on admin.target.com for unindexed endpoints"

# Vulnerability & Threat Audits
"Look up known CVEs for OpenSSH version 8.2p1"
"Check if cloud storage buckets exist for domain fincorp-assets.com"
"Detect dangling CNAME records susceptible to subdomain takeover on cloudapp.net"
"Query Have I Been Pwned for breaches associated with security@enterprise.com"

Port Scan Profiles

The port_scan tool supports multiple scanning strategies tailored to operational velocity and assessment depth:

Example invocation:

Scan target scanme.nmap.org using the 'service' profile.

End-to-End Threat Modeling with threat_analysis Prompt

For optimal threat intelligence synthesis in supported MCP clients:

1. In your MCP client (e.g. Claude Desktop), click the + icon in the prompt input area.
2. Select Connectors → Add from AynOps.
3. Choose the threat_analysis prompt template.
4. Execute your target reconnaissance prompt:

   Do a complete security recon on scanme.nmap.org
   

5. The LLM will invoke full_recon, process the normalized signals, and generate a correlated matrix mapping open ports to potential CVEs, missing headers, email spoofability, and infrastructure risk factors.

💡 Examples

Scenario 1: CVE Patch Validation and Vulnerability Correlation

User: Run a service scan on our perimeter host and cross-reference detected software with NVD for CVEs.

Agent: [Invokes port_scan with scan_type="service"]
       Discovered Open Services:
       • Port 80/tcp: Apache httpd 2.4.49
       • Port 22/tcp: OpenSSH 7.4

       [Invokes cve_lookup for software="apache", version="2.4.49"]

📦 Registries & Ecosystem

AynOps is indexed and distributed across the following official registries:

🤖 LLM Client Behavior & Security Considerations

AynOps acts strictly as an execution server over MCP. Tool invocation decisions, parameter synthesis, and prompt chaining are governed by the connected LLM client:

• Model Guardrails & Safety Filters: Certain LLM providers (e.g., Anthropic, OpenAI) enforce heuristic safety filters. Queries like "Attack example.com" or even standard phrases like "Port scan example.com" can occasionally be declined by commercial frontends.
  • Workaround 1: Phrase prompts defensively (e.g., "Audit the defensive security posture of our infrastructure at example.com").
  • Workaround 2: Connect AynOps to developer-centric or unconstrained MCP clients (e.g., Cursor, Continue.dev with local models via Ollama, or our upcoming AynOps Dedicated Client).
• Execution Timeouts: Large operations (such as full port scans across all 65,535 ports) may exceed default client JSON-RPC timeout thresholds (typically 60–120s). Configure tool timeouts appropriately or use the basic and service profiles.
• Parameter Extraction Fidelity: Ensure your prompts provide fully qualified domain names (FQDNs) or valid IPv4/IPv6 addresses to prevent client-side schema validation errors.

⚖️ Legal & Ethical Usage

[!CAUTION] Only perform active network scans and vulnerability evaluations against infrastructure you own or have explicit, documented authorization to test.

• Passive OSINT Tools (whois_lookup, dns_enumeration, asn_lookup, cert_transparency, headers_analyzer, cve_lookup, robots_txt_inspect): Operate purely against publicly advertised records and standard web responses.
• Active Scanning Tools (port_scan, cloud_exposure_check, subdomain_takeover): Send active network traffic. Unauthorized scanning may violate the Computer Fraud and Abuse Act (CFAA), GDPR, and local cyber regulations.
• Authorized Testing Host: For testing and demonstration purposes without production risk, use the officially designated Nmap test host: scanme.nmap.org.

⚠️ Known Limitations

• OS Detection Privileges: Nmap OS fingerprinting (scan_type="os") relies on raw TCP/IP socket crafting (-O) and requires elevated root / Administrator privileges on the host system.
• Upstream OSINT Rate Limiting: Tools interfacing with third-party endpoints (e.g., crt.sh Certificate Transparency logs, NIST NVD v2 REST API) are subject to upstream service availability and rate limits.
• API Key Dependencies: ip_reputation and hibp_check require valid API keys configured in environment variables to return live telemetry.
• Container Stdio Lifecycle: When deploying via Docker, the container must maintain an attached interactive stdio stream; running in detached daemon mode (-d) will terminate the MCP pipe.
