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: Prosopo
Prosopo is a bot and agent trust layer that replaces reCAPTCHA with risk-based enforcement, and its distinguishing idea is that AI agents are now a third traffic class rather than simply another kind of bot. Every request is scored for intent — human, trusted agent, or abusive automation — and verification is only applied when a risk threshold is crossed, so legitimate visitors usually pass invisibly and never see a challenge at all. The product line covers a GDPR-compliant CAPTCHA, an invisible verification mode with a challenge fallback, access control, risk scoring, API protection and a spam filter, and the company builds around a privacy-first architecture that minimises data collection and avoids cross-site tracking, which is the practical argument for European teams that cannot ship Google's reCAPTCHA past their DPO. Documented use cases are the abuse patterns that actually cost money: scraping, denial of inventory, credential stuffing, account takeover, click fraud, ticket scalping and loyalty-programme automation. For security and platform teams there are audit logs and rule-based access control, and deployment covers web, mobile and API patterns. The higher tier adds network-wide behavioural modelling for human-versus-agent intent, residential proxy and real-device farm detection, and in-app browser detection.
Ideal use cases:
- •Teams or individuals who need real-time risk scoring of every request for human, agent or bot intent
- •Teams or individuals who need invisible verification with challenge fallback
- •Teams or individuals who need gdpr-compliant, privacy-first architecture with no cross-site tracking
- •Teams or individuals who need access control rules and audit logs for platform teams
- •Anyone focused on captcha workflows
- •Anyone focused on bot-detection workflows
