TOPY.AI · AI CSO

TOPY AI CSO Skills 19 skills that make your coding agent a small company's AI CSO: new CVEs and end-of-life dates for everything you run, no secrets in code, headers, TLS and safe scans of the domains you have verified, every skill and MCP server vetted before it is trusted, incident timelines and a weekly security report to the founder and the CEO — on the TOPY.AI CSO MCP server.

---

The AI CSO is goal-first. It keeps five standing goals — no open critical exposure (anything on CISA KEV or critical with a fix is fixed within days), zero secrets in code, verified-only active checks, nothing trusted unvetted (every new skill, MCP server and package checked first) and every incident with a timeline — and every skill below exists to move one of them.

• Core (topy-ai-cso): connect, first setup (inventory, domain verification, host consent), the CSO's goals, the daily watch.
• Vulnerabilities: are we affected by this CVE, dependencies and supply chain, end of life, vetting a package before install.
• Code: secrets (rotate first, then remove), unsafe code patterns, a STRIDE threat model and the OWASP ASVS checklist.
• Web: domain verification, headers and TLS, a safe scan of a verified site.
• Agents: vet a skill or MCP server before it is installed (the App Factory gate), and audit your own MCP server.
• Response: incident timelines, a fix plan with fix-risk tiers T1–T4, the weekly security report.

The safety model comes from Maggie Security and does not bend: the CSO never changes a server, firewall or website (fix and protection plans are for a person to review and apply), never scans a domain you have not verified, reads a server only after you grant consent yourself, by your own approval in the chat (an agent cannot), leaves checks of sites you don't control to a person (never a routine), never uses offensive techniques and never prints a secret. Changes take two calls — a preview, then your yes.

Connect TOPY.AI

https://topy.ai/mcp/cso — OAuth with your TOPY.AI account (the same one as the AI CEO, CFO and COO). Only the accounts that own the OneMan operation see its findings.

Server checks (host-quick, host-audit) and passive checks of sites you don't control (public-check) are not on topy.ai: they need a person on OneMan, with host consent granted by the person's own approval in the chat.
