How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score → Why this is hard to score →

Supply Chain Security100
  • No malware found by supply-chain analysis.Pass
  • No known CVEs affecting this package version or its production dependencies.Pass
  • No install/post-install scripts declared.Pass

  • Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability57
  • AI-judged instruction clarity (good).Pass
  • Context-footprint check failed: tool/resource definitions use about 1109 tokens (~369/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
  • Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management23
  • Stability observed for 7 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
Tool Coverage100
  • 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
  • 100% of tool parameters carry a description.Pass
Tool Safety100
  • No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
  • We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
  • An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

MCP tools · 3 exposed · ~1,056 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
crawlbase_scrape ~433

Scrape any website through Crawlbase rotating residential proxies with server-side anti-bot bypass (Cloudflare, DataDome, hCaptcha solved for you). Returns the page as HTML (default), clean markdown (format:"md" — great for LLM context), or a JSON envelope with metadata (format:"json"). JavaScript-heavy pages (SPAs) render when you pass your Crawlbase JavaScript token as _apiKey; the Normal token does fast static fetches. Example: crawlbase_scrape({ url: "https://example.com", format: "md", _apiKey: "your-crawlbase-token" })

NameTypeReqDescription
_apiKeystringyesYour Crawlbase token — Normal token for static pages, JavaScript token for rendered pages. Free tier (10,000 requests) at https://crawlbase.com
ajax_waitboolean–Wait until the network is idle before capturing (JavaScript token required). Best for SPAs that fetch data after mount.
countrystring–Two-letter ISO country code to route the crawl through, e.g. "US", "GB", "DE", "JP". Default: automatic geo selection.
devicestring–Device profile to emulate: "desktop" (default), "tablet", or "mobile".
formatstring–Response shape: "html" (default, raw page), "md" (GitHub-flavored markdown, LLM-friendly), or "json" (page + metadata in one JSON envelope).
javascriptboolean–Set true when the page needs JavaScript rendering (SPAs, lazy-loaded feeds). Crawlbase selects rendering by TOKEN TYPE, so when this is true you must pass your Crawlbase JavaScript token as _apiKey (…
page_waitnumber–Milliseconds to wait after page load before capturing (JavaScript token required). Useful for content that animates in.
urlstringyesThe absolute URL to scrape including scheme, e.g. "https://example.com/page"

No examples provided.

crawlbase_screenshot ~306

Capture a screenshot of a rendered web page via Crawlbase (headless browser + rotating proxies, anti-bot bypass). Returns a stored screenshot_url (JPEG, link expires after about one hour) plus crawl metadata. Requires your Crawlbase JavaScript token as _apiKey — screenshots always render in a real browser. Captures the full page by default; pass mode:"viewport" with width/height to constrain. Example: crawlbase_screenshot({ url: "https://example.com", _apiKey: "your-js-token" })

NameTypeReqDescription
_apiKeystringyesYour Crawlbase JavaScript token (screenshots require browser rendering). Free tier at https://crawlbase.com
countrystring–Two-letter ISO country code to route through, e.g. "US", "GB".
heightnumber–Viewport height in pixels (only applies with mode:"viewport").
modestring–Capture mode: full rendered page by default; "viewport" captures only the visible area (pair with width/height).
page_waitnumber–Milliseconds to wait after page load before capturing — gives animations/JS time to settle.
scrollboolean–Scroll the page before capture to trigger lazy-loaded content.
urlstringyesThe absolute URL of the page to screenshot, e.g. "https://example.com"
widthnumber–Viewport width in pixels (only applies with mode:"viewport").

No output schema declared.

No examples provided.

crawlbase_structured ~317

Scrape a page into clean structured JSON using a named Crawlbase scraper — skip HTML parsing entirely. Common scraper names: "amazon-product-details", "amazon-serp", "google-serp", "facebook-page", "facebook-profile", "instagram-profile", "instagram-post", "linkedin-profile", "linkedin-company", "tiktok-profile", "ebay-product", "walmart-product-details", "github-repository", "generic-extractor". Full catalog: https://crawlbase.com/docs/scrapers/ — social-media scrapers (Facebook/Instagram/LinkedIn) work best with your JavaScript token. Example: crawlbase_structured({ url: "https://www.amazon.com/dp/1098145356", scraper: "amazon-product-details", _apiKey: "your-crawlbase-token" })

NameTypeReqDescription
_apiKeystringyesYour Crawlbase token (JavaScript token recommended for social-media scrapers). Free tier at https://crawlbase.com
countrystring–Two-letter ISO country code to route through, e.g. "US", "DE". Matters for localized storefronts and SERPs.
scraperstringyesThe Crawlbase scraper name to apply, e.g. "amazon-product-details", "google-serp", "linkedin-profile". Catalog: https://crawlbase.com/docs/scrapers/
urlstringyesThe absolute URL of the page to scrape, e.g. "https://www.google.com/search?q=coffee" for google-serp.
