nmap-scan-management

nmap-scan-management is a skill for Claude Code from automateyournetwork/netclaw. It costs 48 tokens per session (1,208 once invoked), scanned A, original, Apache-2.0.

A manager for custom nmap scans, where nmap is a tool that probes hosts and ports to discover network exposure. It can run scans with custom options and save results for later retrieval or comparison.

In plain words
What is it for?
Use it to run scoped custom scans, list previous scans, retrieve a scan by ID, and compare results from before and after a change.
Why use it?
It supports scan settings that purpose-built scan commands do not cover and avoids repeating scans when an earlier result is sufficient. Before-and-after comparisons make changes easier to check.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

nmap-scan-management scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How to Call the nmap MCP Tools

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" TOOL_NAME '{"param":"value"}'

When to Use

  • Run nmap with flags not covered by the purpose-built tools
  • Review past scan results without re-scanning
  • Compare before/after scans (pre-change vs post-change)
  • Retrieve a specific scan result by ID

Available Tools

Tool Purpose
nmap_custom_scan Run nmap with arbitrary flags (scope-enforced + audit-logged)
nmap_list_scans List recent saved scans with IDs, timestamps, targets
nmap_get_scan Retrieve full results of a previous scan by ID

Custom Scans

For power users who need flags not covered by the dedicated tools:

# Aggressive scan with version detection
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"192.168.1.1","flags":"-A -T4"}'

# Scan specific ports with timing template
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"10.0.0.0/24","flags":"-sS -p 22,80,443 -T3 --open"}'

# Idle scan using a zombie host
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"192.168.1.1","flags":"-sI 192.168.1.254"}'

# IPv6 scan
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_custom_scan '{"target":"fd00:cc:1:2::1","flags":"-6 -sT -p 179,22,80"}'

Safety: The following are blocked in custom scans:

  • Shell metacharacters (;, &, |, `, $, etc.)
  • Output-writing flags (-oN, -oX, -oG, -oA)
  • Path-based flags (--datadir, --servicedb, --script with path)

Use the dedicated nmap_script_scan or nmap_vuln_scan tools for NSE scripts.

Scan History

List Recent Scans

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_list_scans '{"limit":20}'

Returns newest-first list with scan_id, timestamp, tool used, and target.

Retrieve a Specific Scan

python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_get_scan '{"scan_id":"20250307_143022_a1b2c3"}'
