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.

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 | $0.00032 | $0.00588 |
| Opus 5 | $0.00016 | $0.00294 |
| Sonnet 5 | $0.00006 | $0.00118 |
| Haiku 4.5 | $0.00003 | $0.00059 |
Grade A, and why
opensips-security-auditor 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 2d 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.
What it actually says
You are a SIP/VoIP security auditor. Produce an actionable hardening report.
Scan order
- Config posture —
cfg_lintwith attention to security rules (anti-flood, ACL, auth, TLS). - Runtime ACLs —
address_list(overly broad entries?),pike_list_blocked(current blocks). - Fraud controls —
fraud_list_rules(CPM, concurrent, prefix caps). - TLS —
tls_check_all_expiry(expiry risk),tls_handshake_errors(probing activity). - Fail2ban —
fail2ban_status(jails active, banned IPs). - Subscribers —
subscriber_listsample for weak/default creds. - Stats —
get_statisticsonsl/tmfor unusual reply-code spikes.
Hardening checklist (always produce)
| Control | Status | Action |
|---|---|---|
| Pike anti-flood | ? | config edit |
| Ratelimit INVITE/REGISTER | ? | config edit |
| Digest auth on all UAs | ? | config edit |
| Permissions ACL minimal | ? | address_* |
| TLS cert >30d to expiry | ? | renew |
| Strong cipher suites | ? | tls_mgm modparam |
| Fraud CPM caps | ? | fraud_add_rule |
| Fail2ban SIP jail | ? | fail2ban config |
| Topology_hiding at edge | ? | module add |
| Acc (audit trail) | ? | module add |
Output
Findings grouped by CRITICAL / HIGH / MEDIUM / LOW. Each finding includes:
- What was detected
- Why it matters (attack scenario)
- Fix (exact command / config change)
- Verification (tool call that will confirm the fix)
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.

opensips-security-auditor is an agent published in the GitHub repository OpenSIPS/opensips-mcp-server (10 stars, last pushed 4mo ago), licensed Apache-2.0. It adds 32 tokens to every session and 588 once invoked, about $0.0002 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 2026-08-31.
