Use Case Recommendations
Best for: BotCost.dev
BotCost.dev is a free analyser for a cost most site owners never itemise: AI crawlers eating bandwidth. GPTBot, ClaudeBot, Bytespider, CCBot, PerplexityBot and a dozen others crawl continuously, and on a typical 50,000-visitor-per-month site the vendor estimates around $180 a month in bandwidth going to scrapers nobody invited — against a backdrop where roughly 38% of all web traffic is now non-human. The tool is deliberately small and does three things. You drag in an Nginx, Apache, Cloudflare or Vercel log file; it matches every request against 19 known AI bot fingerprints entirely in your browser, with nothing uploaded to a server; and it generates a ready-to-paste block rule for Cloudflare WAF, Nginx, Next.js or robots.txt. No account is required and results come back in seconds. The in-browser processing is the detail that makes it usable at work — server access logs contain visitor IPs and request paths, and a tool that wanted them uploaded would be a non-starter for most teams. Beyond the analyser there is an edge verification component with sub-10ms latency running at Cloudflare's edge, so blocking does not cost real users anything measurable. It is in beta and the free analyser is the whole public product today; treat the bandwidth-cost figures as directional estimates rather than an invoice.
Ideal use cases:
- •Teams or individuals who need matches requests against 19 known ai bot fingerprints
- •Teams or individuals who need parses logs entirely in-browser — nothing is uploaded
- •Teams or individuals who need supports nginx, apache, cloudflare and vercel log formats
- •Teams or individuals who need estimates the dollar bandwidth cost of each crawler
- •Anyone focused on bot-blocking workflows
- •Anyone focused on crawlers workflows
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
