About

Naabu

Fast port scanner powered by ProjectDiscovery's naabu. Runs locally via MCP server wrapper around the naabu binary.

Capabilities

  • TCP SYN/CONNECT port scanning
  • Top 100/1000 port presets (nmap-compatible)
  • CIDR range scanning
  • JSON Lines output for structured results
  • Passive scanning via Shodan InternetDB (no packets sent)
  • Service version detection (via nmap passthrough)

Workflow Routing

| Action | Trigger | Behavior | |--------|---------|----------| | Scan Ports | "scan ports on", "check open ports", "port scan" | Run naabu against target | | Quick Scan | "quick scan", "top ports" | Scan top 100 ports | | Full Scan | "full port scan", "all ports" | Scan all 65535 ports | | Passive Scan | "passive scan", "no packets" | Use Shodan InternetDB |

Examples

Example 1: Scan top ports on a host

User: "Scan the top ports on example.com"
→ naabu -host example.com -top-ports 100 -json -silent
→ Returns JSON list of open ports

Example 2: Scan specific ports on a subnet

User: "Check if SSH and HTTP are open on 192.168.1.0/24"
→ naabu -host 192.168.1.0/24 -p 22,80,443 -json -silent
→ Returns open port findings per host

Example 3: Passive recon (no packets)

User: "Do a passive port scan on example.com"
→ naabu -host example.com -passive -json -silent
→ Returns known open ports from InternetDB without sending packets

CLI Reference

# Key flags
naabu -host        # Single host, IP, or CIDR
naabu -list          # File with targets (one per line)
naabu -p 22,80,443         # Specific ports
naabu -top-ports 100       # Top 100 or 1000 ports
naabu -json                # JSON Lines output
naabu -silent              # Suppress banner/info
naabu -passive             # Shodan InternetDB lookup (no packets)
naabu -Pn                  # Skip host discovery
naabu -rate 1000           # Packets per second
naabu -o results.jsonl     # Output to file

JSON Output Format

Each open port produces one JSON line:

{"ip":"93.184.216.34","port":80}
{"ip":"93.184.216.34","port":443}

MCP Server

The MCP server (tools/mcp-server.ts) wraps the naabu binary and exposes it as a local stdio MCP tool. Configured in ~/PAI/.mcp.json.

Requirements

  • naabu binary in PATH (~/bin/naabu)
  • libpcap (brew install libpcap)
