Use Case Recommendations
Best for: DepScope
DepScope is a free MCP server that screens every package an AI agent suggests before it reaches npm install. It targets three specific failure modes. The first is hallucination: LLMs invent plausible-sounding package names, and DepScope verifies each one against live registries across 19 ecosystems and flags typosquats by Levenshtein distance to popular packages — the exact mechanism attackers rely on when they register a name a model is likely to hallucinate. The second is vulnerability exposure, covered by live lookups against OSV, CISA's Known Exploited Vulnerabilities list, EPSS scores, the OpenSSF malicious-package feed, and a deprecated-package index, returning severity, fix version, and migration path in one call. The third is token cost: pre-curated briefs of roughly 300 tokens replace the four-to-eight thousand tokens an agent would otherwise burn scraping registry and CVE pages per decision, a reported 74% reduction. It covers 8.5 million packages across 19 ecosystems — npm, PyPI, Cargo, Go, Composer, Maven, NuGet, RubyGems, pub, hex, Swift, CPAN, Hackage, CRAN, conda, Homebrew, JSR, and Julia — with 22 MCP tools, no auth, no API key, and no rate limit. Remote MCP works out of the box in Claude Desktop, Cursor, and Windsurf, with a curl one-liner for everything else, and the SDKs are open source. There is also a browser paste-a-manifest scan and a published ten-model hallucination benchmark.
Ideal use cases:
- •Teams or individuals who need hallucination guard verifies packages against live registries in 19 ecosystems
- •Teams or individuals who need typosquat detection by levenshtein distance to popular package names
- •Teams or individuals who need live cve intel from osv, cisa kev, epss, and the openssf malicious feed
- •Teams or individuals who need severity, fix version, and migration path returned in one call
- •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Lovable and Claude optimise for working code rather than safe code and routinely emit vulnerable patterns or reach for outdated packages.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
