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 5.1 | $0.00108 | $0.01521 |
| Opus 5 | $0.00054 | $0.00760 |
| Sonnet 5 | $0.00022 | $0.00304 |
| Haiku 4.5 | $0.00011 | $0.00152 |
Grade A, and why
agentaegis-security 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 11d 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 it starts
The opening of the file, as written. The whole thing — 93 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AgentAegis security scans
AgentAegis is a hosted MCP server that runs real security scanners (nmap, Nuclei, sslyze, Semgrep, trufflehog, trivy) and queries real threat-intel feeds (NVD, AbuseIPDB, AlienVault OTX, abuse.ch, HIBP). Findings describe real infrastructure.
Setup
Add the server to your MCP client:
{
"mcpServers": {
"agentaegis": {
"url": "https://agentaegis-mcp-production.up.railway.app/mcp",
"headers": { "Authorization": "Bearer aegis_YOUR_API_KEY_HERE" }
}
}
}
Get a key at https://agentaegis.org/pay. Alternatively, omit the header and pay per call in USDC on Base via x402 — no signup, the server answers with an HTTP 402 challenge your x402-capable client settles automatically.
If the tools are not available, the server is not connected. Say so rather than guessing at answers this skill is meant to measure.
Cost — this skill spends real money
Tools cost $1 to $5 per call, charged when the call is made. A scan that returns nothing useful still costs.
- Before the first paid call in a conversation, tell the user which tool you plan to call and what it costs, and wait for their agreement.
- Never run a scan the user did not ask for. Never call paid tools to explore the catalog.
- Never retry a paid tool in a loop. On error, report it and stop.
Free, always: help, account_balance, agent_whoami, agent_history, agent_scan_get.
Call help for exact current pricing rather than quoting numbers from memory.
Always check for a prior result first
Every paid scan is stored. agent_history lists your prior scans and agent_scan_get returns any one of them in full, both free. When the user asks about a target you have looked at before, retrieve it instead of re-paying. Only re-scan when they want fresh data or the earlier scan is stale.
Choosing a tool
| The user is asking | Use |
|---|---|
| Is this endpoint/domain safe to call, trust or pay? | vet_endpoint |
| Should I install this MCP server or plugin? | scan_mcp_plugin |
| Should I trust this agent skill? | scan_skill |
| What is CVE-YYYY-NNNNN? | cve_lookup |
| Is this IP or domain malicious? | threat_intel_lookup |
| Can our email be spoofed? | email_security_audit, or dns_security_check for records only |
| Is our TLS configured correctly? | ssl_tls_audit |
| Are there vulnerabilities in this code? | sast_scan |
| Are there hardcoded secrets? | secret_scan |
| Are our dependencies vulnerable? | dependency_audit |
| What ports are exposed? | vuln_scan_network |
| Is this web app vulnerable? | vuln_scan_web_app |
| Are we SOC 2 / ISO 27001 / HIPAA / PCI-DSS / NIST CSF ready? | compliance_framework_check |
| We have an incident | incident_triage |
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.

agentaegis-security is a skill published in the GitHub repository astafford8488/agentaegis-mcp (1 stars, last pushed 1mo ago), licensed MIT. It adds 108 tokens to every session and 1,521 once invoked, about $0.0005 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 2026-08-30.
