What we checked

Six static checks, weighted by risk. Every result reflects only what could be observed in the published package and repository — never intent.

• Injection surface

  unscannable25% of grade

  Tool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).

  No tool descriptions, server instructions, prompts, or resources were fetched; nothing to scan for injection.

• Supply chain

  fail25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  Python build script executes at build time: network call in build script

• Credential hygiene

  pass15% of grade

  How the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.

  Reads secrets from the environment (e.g. src/pyscrappy/scrapers/imdb.py) — the recommended intake shape. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• Permission scope

  warn15% of grade

  Declared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.

  discloses broad/destructive filesystem access: src/pyscrappy/scrapers/image_search.py: open(…, 'w'/'a'/'x') write-mode file access Capability DISCLOSURE, not a verdict: static analysis sees the primitive is present and reachable, not whether its use is attacker-controlled.

• Version behavior

  fail10% of grade

  Diff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).

  vs prior 1.5.5 (patch bump): new capability primitive(s) in source: fs-write, http-client; new hardcoded outbound host/BCC destination(s): ..., 127.0.0.1, a, a.com, api.coingecko.com, api.com, api.dictionaryapi.dev, api.example.com, api.github.com, api.open-meteo.com, api.scraperapi.com, app.scrapingbee.com, b, b.com, base.com, c, covers.openlibrary.org, ebay.com, en.wikipedia.org, example.com, external.com, feeds.bbci.co.uk, finance.yahoo.com, fr.wikipedia.org, geocoding-api.open-meteo.com, github.com, hn.algolia.com, host, i.ytimg.com, images.example.com, img.amazon.com, img.com, img.newegg.com, linkedin.com, natgeo.com, news.ycombinator.com, open.er-api.com, open.spotify.com, openlibrary.org, pic.com, proxy, proxy.scrapeops.io, query1.finance.yahoo.com, real.com, rss.nytimes.com, schema.org, scrapeops.io, sik.search.blue.cdtapps.com, soundcloud.com, source.com, source2.com, spa-site.com, thumb.com, user, www.bbc.com, www.bing.com, www.google.com, www.ikea.com, www.imdb.com, www.instagram.com, www.linkedin.com, www.newegg.com, www.omdbapi.com, www.scraperapi.com, www.scrapingbee.com, www.ubereats.com, www.w3.org, www.youtube.com, www.zomato.com, x, x.com.

• Transport config

  warn10% of grade

  Remote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.
