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: ZeroLeaks
ZeroLeaks runs continuous red-team scans against AI agents, endpoints and MCP tools, looking for prompt injection, data leakage and unsafe actions — then re-tests to verify each fix actually closed the hole. You point it at a system prompt, a live agent endpoint or a set of tool definitions, and a team of specialised attack agents plans, executes and validates attacks in minutes. The probe library is the differentiator: it is grounded in thousands of documented real-world prompt leaks and jailbreaks catalogued by the team behind a 100k-plus-star repository, rather than a synthetic checklist that gets stale the week after it ships. Coverage spans prompts, tool calls, MCP servers, RAG pipelines and extended multi-turn conversations, which is where a lot of injection actually lands. The CI/CD path is what makes it a testing tool rather than an audit: connect a repository and every pull request that changes agent behaviour gets scanned, with findings posted as checks and merge gates so risk cannot reach production silently. Every finding ships with reproducible evidence, a severity ranking and guided remediation, plus hardening validation to prove the vulnerability is closed rather than merely flagged. Reports export to PDF for security and compliance review. The pricing stance is unusual and deliberate: scans are unlimited on every plan, so testing more often never costs more — the meter is on seats and features, not diligence. Pro, Team and Business all check out self-serve with no demo wall.
Ideal use cases:
- •Teams or individuals who need attack agents that plan, execute and validate in minutes
- •Teams or individuals who need probe library built from real documented exploits
- •Teams or individuals who need coverage across prompts, tools, mcp servers and rag
- •Teams or individuals who need github pr merge gates on behaviour changes
- •Anyone focused on security workflows
- •Anyone focused on red-teaming workflows
