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
warn25% of gradeTool descriptions/manifest scanned for instruction-injection patterns (imperatives at the model, hidden text, 'ignore previous', data-exfil URLs).
tool "search_events" description: cross-tool redirection ('instead of call…').
Supply chain
warn25% of gradePackage provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.
no resolvable repository linked to the package (provenance unverifiable)
Credential hygiene
pass15% of gradeHow the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.
No hardcoded secrets, secret-shaped tool parameters, or leaked keys found. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.
Permission scope
unscannable15% of gradeDeclared tools vs. breadth (filesystem, network, exec); flags shell-exec and unbounded filesystem access.
No source files, package.json, or pyproject were fetched; cannot infer capability scope.
Version behavior
warn10% of gradeDiff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).
vs prior 1.0.1 (patch bump): tool "company_events" description changed (wording only, no injection pattern); tool "list_event_types" description changed (wording only, no injection pattern); tool "feed_health" description changed (wording only, no injection pattern).
Transport config
pass10% of gradeRemote servers: TLS and auth mode (none/token/OAuth). Local servers: whether the manifest indicates it phones home.
remote endpoint "https://mcp.apify.com/?tools=datasignalslab/datasignals-events-mcp" uses TLS (https); remote endpoint "https://datasignalslab--datasignals-events-mcp.apify.actor/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
Version history
Each release plotted by grade against the safe line at B. A version that sinks below the line has lost its trusted standing — the shape of a rug-pull.
