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: PreBreach
PreBreach is a security scanner aimed specifically at applications assembled with AI coding tools, on the argument that Cursor, Bolt, Lovable and Claude optimise for working code rather than safe code and routinely emit vulnerable patterns or reach for outdated packages. A scan starts from a project URL or a GitHub repository with nothing to install, and runs eight security-layer agents across authentication, authorisation, injection, infrastructure, business logic, client-side, API security and reconnaissance, mapped to the OWASP Top 10 and scored with CVSS v4.0 and CWE identifiers. The differentiator the vendor leans on is validation rather than detection: every finding is independently analysed by both Claude and GPT and scored by consensus vote, disagreements are flagged, and the published false-positive rate is under 5%. Findings ship with proof-of-concept scripts demonstrating that the vulnerability is real, and with copy-paste remediation prompts written for the same AI coding tool that produced the code, so the fix loop stays inside the developer's existing workflow. The scanner also runs 24 custom Nuclei templates built for modern stacks — Supabase, Next.js, Firebase, Vercel and Clerk. Reports are delivered as PDF, JSON and interactive HTML, and a typical scan takes 30 to 60 minutes with live progress in the dashboard. Domains are DNS-verified before scanning.
Ideal use cases:
- •Teams or individuals who need eight security-layer ai agents mapped to the owasp top 10
- •Teams or individuals who need every finding validated independently by claude and gpt
- •Teams or individuals who need proof-of-concept scripts proving each vulnerability is real
- •Teams or individuals who need remediation prompts written for cursor, bolt and other ai editors
- •Anyone focused on security workflows
- •Anyone focused on owasp workflows
