TOPY.AI · AI CSO

---

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 in a terminal (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.

Client	How
Claude, ChatGPT (web, desktop)	custom connector https://topy.ai/mcp/cso
Claude Code	claude mcp add --transport http topy-cso https://topy.ai/mcp/cso
Codex	codex mcp add topy-cso --url https://topy.ai/mcp/cso
Clients that only start a command	npx -y @topy-ai/cso-mcp after npx @topy-ai/cso-mcp login
Terminal and scripts	npm i -g @topy-ai/cso-cli && cso-cli login

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 in a terminal.

AI CSO core (MCP) · topy-ai-cso

Skill	Tier	What it does
topy-cso-connect	core	Connect the TOPY CSO MCP server and check what applies: the project's stack, verified domains, granted hosts, tools and feeds.
topy-cso-daily-watch	core	Every morning: new CVEs, advisories and end-of-life dates for everything the company runs, matched to the stack — quiet unless something new needs a person.
topy-cso-goals	core	The AI CSO's standing goals and its status report for the CEO: open critical exposure, secrets in code, verified-only checks, vetted skills and MCP servers, incident timelines.
topy-cso-setup	core	First run for a new company or site: inventory the stack, verify each domain you own, and explain host consent — so every later check is allowed and complete.

Vulnerabilities & supply chain · topy-ai-cso-vulnerabilities

Skill	Tier	What it does
topy-cso-cve-response	connected	A named CVE or advisory: are we affected, where, how urgent, and the response plan — with an incident timeline from start to close.
topy-cso-dependencies	connected	Known vulnerabilities in every lockfile ecosystem and in JavaScript copied into the site, prioritised, with the fixed versions.
topy-cso-end-of-life	connected	Runtimes, databases, web servers and operating systems that stopped (or will soon stop) getting security fixes, and what to upgrade to.
topy-cso-package-vet	connected	Before adding a package: known vulnerabilities and malicious-package reports for that exact version, and a clear install / pin / don't install.

Code & secrets · topy-ai-cso-code

Skill	Tier	What it does
topy-cso-code-scan	connected	Unsafe code patterns before they ship — injection, unsafe deserialisation, personal data in logs, weak crypto — with the safe pattern for each.
topy-cso-secrets	connected	Keys, tokens and passwords in the code, its git history and the build output — and the rotate-first fix for each.
topy-cso-threat-model	connected	A STRIDE threat model of the system and an OWASP ASVS checklist filled from the findings — what could go wrong and how far we meet the standard.

Web surface · topy-ai-cso-web

Skill	Tier	What it does
topy-cso-domain-verify	connected	Prove the company controls a domain (DNS TXT record or a token file) before any active check — the CSO never scans a site that isn't verified.
topy-cso-web-checks	connected	Grade a verified site's HTTP security headers and cookies (A+ to F) and its TLS (protocols, certificate trust and expiry), with the exact fix for each.
topy-cso-web-scan	connected	A safe, rate-limited vulnerability scan (known flaws, exposed files, misconfigurations) of a site the company has verified — never exploitation.

Agent & MCP security · topy-ai-cso-agents

Skill	Tier	What it does
topy-cso-mcp-audit	connected	OWASP MCP checks on the company's own MCP tool registry: read-only hints, destructive tools behind confirmation, scopes, audit logging and hosts it may call.
topy-cso-vet-skill	connected	Before a skill, plugin or MCP server is installed or published: prompt-injection, data exfiltration, over-broad permissions and risky tools — the App Factory security gate.

Response & reporting · topy-ai-cso-response

Skill	Tier	What it does
topy-cso-fix-plan	connected	Turn the findings into a reviewed runbook — each action tagged T1 (batch-safe) to T4 (stage first) — that a person reviews and runs. The CSO never applies it.
topy-cso-incident	connected	Record a security incident or CVE response from start to close — what happened, every step and who did it — so nothing is lost and the report writes itself.
topy-cso-weekly-report	connected	Every Monday: what is open by priority, what was fixed, what changed in the stack, and at most three actions — for the Founder by email and for the CEO.
