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: Guardr
Guardr is a security and uptime monitor aimed at the people who look after other people's websites — web agencies with twenty client sites, freelancers who get asked whether a site has security problems, and solo developers who would otherwise never run these checks. A scan takes about five seconds, requires no signup and works on any site: it covers SSL certificate state, security headers, DNS, exposed files, secrets leaked into JavaScript bundles and cookie configuration, returning an A–F grade with a plain-English fix for every issue rather than a raw findings dump. Once you sign up it moves from a one-off scan to continuous monitoring, checking 24/7 from three global regions and alerting the moment something changes — an expiring or misconfigured certificate that would otherwise show visitors a full-page browser warning, injected content, or plain downtime. The framing for agencies is commercial rather than technical: it turns 'is my site secure?' from an open-ended rabbit hole into a line item on a retainer with an artefact behind it. The site reports over 10,400 sites scanned. The first site is free forever, which makes it usable as a permanent monitor on a personal project without a card, and there are docs and a blog alongside the product.
Ideal use cases:
- •Teams or individuals who need five-second scan with no signup on any domain
- •Teams or individuals who need checks ssl, security headers, dns, exposed files, js secrets and cookies
- •Teams or individuals who need a–f grade with a plain-english fix per issue
- •Teams or individuals who need 24/7 monitoring from three global regions
- •Anyone focused on uptime-monitoring workflows
- •Anyone focused on security-scanner workflows
