Installation

Prerequisites

# macOS
brew install nmap whois samba dnsutils python3 go

# Install nuclei
go install -v github.com/projectdiscovery/nuclei/v3/cmd/nuclei@latest

# Download nuclei templates
nuclei -update-templates

# Ubuntu/Debian
sudo apt install nmap whois smbclient dnsutils python3 python3-pip golang-go

# Arch Linux
sudo pacman -S nmap whois samba dnsutils python3 go

Install the MCP Server

Configure with Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "pentest": {
      "command": "python",
      "args": ["-m", "pentest_mcp.server"]
    }
  }
}

Usage

1. Set Authorized Scope First

Use set_scope to define your authorized targets:
- targets: ["example.com", "192.168.1.0/24"]
- engagement_id: "PENTEST-2024-001"
- tester_name: "Your Name"

2. Verify Authorization

Before testing any target, verify it's in scope:

verify_authorization(target="example.com")

3. CVE Monitoring Workflow

# Fetch recent critical CVEs
fetch_recent_cves(days=7, severity="critical")

# Search for specific CVEs
search_cve(keyword="log4j")

# Get detailed exploit information
get_cve_exploit_info(cve_id="CVE-2021-44228")

# Add CVE to local database
add_cve_to_db(cve_id="CVE-2021-44228")

4. Nuclei Scanning Workflow

# Check nuclei installation
check_nuclei_status()

# Update templates
update_nuclei_templates()

# Run vulnerability scan
nuclei_scan(target="https://example.com", severity="high")

# Search for templates
search_nuclei_templates(query="cve-2021")

# List critical templates
list_nuclei_templates(severity="critical")

5. Full Penetration Testing Workflow

# Reconnaissance
whois_lookup(domain="example.com")
dns_enum(domain="example.com")
subdomain_enum(domain="example.com")

# Scanning
port_scan(target="example.com", ports="1-1000")
service_detection(target="example.com")

# Enumeration
web_enum(url="https://example.com")

# Vulnerability Analysis
ssl_analyze(target="example.com:443")
nuclei_scan(target="https://example.com", severity="all")

# Reporting
generate_report(format="markdown", include_remediation=true)
