Shodan lookups: internet-connected devices, ports, services. An agent skill from taracodlabs/aiden.

  • Tasks that involve OSINT
  • SKILL.md covers When to Use, How to Use, Examples and Cautions, plus 1 more section
  • Runs TypeScript scripts from its folder; reaches api.shodan.io; needs SHODAN_API_KEY

What it does

Shodan is an agent skill from taracodlabs/aiden. Shodan lookups: internet-connected devices, ports, services

Its SKILL.md is about 950 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `index.ts` and `skill.json`).

It sits in Security, covering OSINT. The repository describes itself as: Aiden — an autonomous AI agent and work engine built solo. It can operate your browser, terminal, files, apps, APIs, skills and tools, remember context, recover from failures… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve OSINT

Example prompts

  • “/shodan”

Requirements

  • Node.js
  • A credential in SHODAN_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 3704204. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (TypeScript), which the agent can run.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • api.shodan.io

    Also links to:

    • account.shodan.io

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • SHODAN_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Shodan loads about 954 tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 263 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~17
When it runs · the whole SKILL.md, loaded when a task matches
~954

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SHODAN_API_KEY

Shodan indexes internet-connected devices and exposes metadata: open ports, running services, banners, TLS certificates, and known CVEs. Use it for security audits, reconnaissance, and asset discovery.

Requires: SHODAN_API_KEY — free tier at https://account.shodan.io (1 req/sec, 100 queries/month).

When to Use

  • User wants to know what ports/services are exposed on a specific IP
  • User wants to find vulnerable systems of a specific type (e.g. exposed databases)
  • User is doing a security audit and needs external exposure info
  • User asks "what does Shodan show for IP X" or "find exposed Redis servers"
  • Asset discovery: find all internet-exposed assets for a company/ASN

How to Use

Look up a specific IP address
powershell
$ip  = "8.8.8.8"
$key = $env:SHODAN_API_KEY
$url = "https://api.shodan.io/shodan/host/${ip}?key=${key}"

$host = Invoke-RestMethod -Uri $url
Write-Host "IP:           $($host.ip_str)"
Write-Host "Organization: $($host.org)"
Write-Host "OS:           $($host.os)"
Write-Host "Country:      $($host.country_name)"
Write-Host "Open ports:   $($host.ports -join ', ')"
Write-Host ""
Write-Host "Services:"
$host.data | ForEach-Object {
    Write-Host "  Port $($_.port)/$($_.transport) — $($_.product) $($_.version)"
}
Search for exposed services by query
powershell
$query = [Uri]::EscapeDataString("port:27017 product:MongoDB")
$key   = $env:SHODAN_API_KEY
$url   = "https://api.shodan.io/shodan/host/search?query=${query}&key=${key}"

$results = Invoke-RestMethod -Uri $url
Write-Host "Total results: $($results.total)"
$results.matches | Select-Object -First 10 | ForEach-Object {
    Write-Host "  $($_.ip_str):$($_.port) — $($_.org) ($($_.location.country_name))"
}
Find CVEs on a host
powershell
$ip   = "TARGET_IP"
$key  = $env:SHODAN_API_KEY
$host = Invoke-RestMethod -Uri "https://api.shodan.io/shodan/host/${ip}?key=${key}"

if ($host.vulns) {
    Write-Host "CVEs found on ${ip}:"
    $host.vulns.PSObject.Properties | ForEach-Object { Write-Host "  $($_.Name)" }
} else {
    Write-Host "No known CVEs found for ${ip}"
}
Useful Shodan search filters
port:22 country:IN                  SSH servers in India
product:nginx version:1.14          Specific nginx version
org:"Amazon"                        Amazon-owned IPs
ssl.cert.subject.cn:*.example.com   Certs for a domain
http.title:"Dashboard" port:80      Web dashboards on port 80
vuln:CVE-2021-44228                 Log4Shell vulnerable hosts

Examples

"What is exposed on IP 1.2.3.4?" → Use the host lookup. Shows open ports, services, OS.

"Find all MongoDB servers with no auth" → Query: port:27017 product:MongoDB -authentication

"Search for Apache servers in India" → Query: product:Apache country:IN

"Does this IP have any known CVEs?" → Use the CVE snippet above on the target IP.

Cautions

  • Free tier: 100 queries/month and 1 request/second — add Start-Sleep -Milliseconds 1100 between bulk calls
  • Shodan data is cached — it reflects the last scan date, not necessarily the current state
  • Host lookups and scans data about publicly reachable services only — no active scanning is performed by this skill
  • Never use Shodan results to attempt unauthorized access; this skill is for reconnaissance and awareness only
  • The vulns field only appears when Shodan has matched CVE data to the service banner
