Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.01497 |
| Opus 5 | $0.00028 | $0.00749 |
| Sonnet 5 | $0.00011 | $0.00299 |
| Haiku 4.5 | $0.00006 | $0.00150 |
Grade A, and why
nmap-service-detection 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.

Service Detection & Vulnerability Scanning with nmap
How to Call the nmap MCP Tools
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" TOOL_NAME '{"param":"value"}'
When to Use
- Identify what software/version is running on an open port
- Fingerprint the OS of a network device or server
- Run targeted NSE scripts (SSL cert check, banner grab, protocol probe)
- Scan for known CVEs and common misconfigurations
- Full reconnaissance sweep of a single host or small range
Available Tools
| Tool | Purpose | Privileges |
|---|---|---|
nmap_service_detection |
Service name + version on open ports (-sV) | none |
nmap_os_detection |
OS fingerprinting (-O) | cap_net_raw |
nmap_script_scan |
Run specific NSE scripts | none |
nmap_vuln_scan |
Run the "vuln" NSE script category | none |
nmap_full_recon |
SYN + service + OS + default scripts all-in-one | cap_net_raw |
Workflow: Service Identification
When asked "what's running on this host?" or "identify the services":
Step 1: Service Version Detection
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_service_detection '{"target":"192.168.1.1","ports":"common","intensity":7}'
Returns per-port: service name, product, version, CPE identifier.
Step 2: OS Fingerprinting
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_os_detection '{"target":"192.168.1.1"}'
Works best when the target has at least one open and one closed port.
Workflow: Security Assessment
When asked "check this host for vulnerabilities" or "security scan":
Step 1: Full Recon
Run the all-in-one audit sweep:
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_full_recon '{"target":"192.168.1.1","ports":"common"}'
This combines SYN scan + service detection + OS fingerprinting + default NSE scripts.
Step 2: Vulnerability Scan
Run the vuln NSE category for known CVEs:
python3 $MCP_CALL "python3 -u $NMAP_MCP_SCRIPT" nmap_vuln_scan '{"target":"192.168.1.1","ports":"common"}'
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

nmap-service-detection is a skill published in the GitHub repository automateyournetwork/netclaw (657 stars, last pushed 6d ago), licensed Apache-2.0. It adds 55 tokens to every session and 1,497 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
