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).
server instructions: off-vendor URL in a description (seishorei-wakarukun.com); capability text should not name where data goes.
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
unscannable15% of gradeHow the server takes secrets (env vs plaintext config vs hardcoded); secrets appearing in tool schemas.
No source files, package manifest, or tool schemas were fetched; cannot assess credential handling.
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
pass10% of gradeDiff of tool definitions between versions; new permissions or changed descriptions in a patch release (the postmark-mcp class).
tool surface, capabilities, install scripts, and publisher unchanged vs prior version 0.3.0 (minor bump); no rug-pull drift.
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://seishorei-wakarukun.com/api/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.
