Use Case Recommendations
Best for: MCP Skills
MCP Skills is a pre-install trust layer for MCP servers and agent skills. It turns public source, package, vulnerability, and supply-chain data into scored pages, trust badges, monitoring, and API workflows you can consult before an unknown tool reaches an agent. The reason it exists is documented on the site: OX Security submitted a benign proof-of-concept malicious MCP server to eleven public registries in April 2026, and nine of them — including LobeHub and Cursor Directory — published it with no security review. Only GitHub rejected it. MCP Skills scores each repository across fifteen trust signals grouped into four dimensions and assigns a tier: Verified means a composite of 7.0 or higher with dimension floors and no disqualifiers, Established means solid with caveats worth checking, and New means promising but unproven. It had scored 2,631 repositories across five registries as of late July 2026, and its own research found 1,184 malicious skills in the ClawHavoc incident and that 36.82% of skills carried at least one security flaw. Maintainers can claim a gold Verified badge on their score page or embed a live trust badge. Access is layered: a free tier allows ten scans per day with compact responses, a single full report costs $2, and Developer Pro adds monitoring and API keys.
Ideal use cases:
- •Teams or individuals who need 15 trust signals across 4 dimensions scored per repository
- •Teams or individuals who need verified / established / new tiering with explicit thresholds and disqualifiers
- •Teams or individuals who need 2,631 repositories scored across 5 registries
- •Teams or individuals who need safety lab for running deeper checks on a server
- •Anyone focused on mcp workflows
- •Anyone focused on supply-chain workflows
Best for: Vibe App Scanner
Vibe App Scanner, or vas, is a security scanner aimed at applications built with AI coding tools — Lovable, Replit, Base44 and similar — where the shipping speed routinely outruns the security review. Its stated difference from a generic scanner is that it tests the live application rather than reading response headers: it probes the database, the auth flow and the APIs the way an attacker would, running more than a hundred and fifty checks that span security, SEO, AI search readiness (AEO and GEO), performance, accessibility, compliance and email configuration. The findings it advertises are the specific ones AI-generated apps produce: Supabase row-level security missing so a profiles table is readable without auth, an exposed .js.map leaking source, an OpenAI key left in a bundled asset, no rate limiting on an auth endpoint. Every finding ships with a fix written for a coding agent to apply, delivered over MCP to Cursor, Claude Code or Windsurf, or as SARIF and copy-paste text, after which you re-scan to confirm the fix landed. Pro adds a weekly automated deep scan that logs in and attempts to reach other users' data across up to a hundred and fifty pages, weekly monitoring with alerts, breach monitoring and email security checks. The first scan is free and returns a score and issue counts without a card; payment unlocks the findings themselves and their fixes.
Ideal use cases:
- •Teams or individuals who need tests the live database, auth flow and apis rather than only response headers
- •Teams or individuals who need 150+ checks spanning security, seo, aeo/geo, performance, accessibility and email
- •Teams or individuals who need fixes delivered over mcp to cursor, claude code and windsurf, plus sarif
- •Teams or individuals who need pro deep scan logs in and attempts to reach other users' data
- •Anyone focused on security workflows
- •Anyone focused on mcp workflows
