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: Xalgorix
Xalgorix is an autonomous penetration-testing agent whose distinguishing rule is that it reports nothing it has not exploited. Point it at a running application or a repository and it works through a twenty-two-phase methodology — reconnaissance, CORS and cookie handling, injection, IDOR, and on through to an explicit exploit-verification phase — and every finding that reaches the report has a working proof attached. That constraint is the answer to the failure mode that makes most automated scanners unusable in practice: a wall of maybe-vulnerabilities that a human has to triage before any of it can be acted on. The published example run is against pentest-ground.com, a deliberately vulnerable public target, and returned nine findings including remote code execution as root via an eval endpoint and a full database dump through auth bypass, in about seventeen minutes, with each exploit reproduced before it was written up. The CI story follows from the same rule: a GitHub Action runs an exploit-verified pass on every pull request and fails the build only on findings it actually proved, at a severity threshold you set, so the gate is on real risk rather than scanner noise. There is a public REST API, signed scan.completed webhooks and an open-source CLI, plus branded PDF reports that are dated and evidence-backed for auditors.
Ideal use cases:
- •Teams or individuals who need 22-phase methodology with an explicit exploit-verification phase
- •Teams or individuals who need every reported finding carries a reproduced working exploit
- •Teams or individuals who need github action fails the build only on proven findings at your severity threshold
- •Teams or individuals who need public rest api, signed scan.completed webhooks and an open-source cli
- •Anyone focused on pentesting workflows
- •Anyone focused on security workflows
