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

  pass25% of grade

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

  repository linkage verified

• Credential hygiene

  fail15% of grade

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

  scripts/init-user.js: contains a hardcoded JWT (eyJh…S4 (len 208)). src/services/supabase-client.js: contains a hardcoded JWT (eyJh…K4 (len 208)). src/config/supabase-config.js: contains a hardcoded JWT (eyJh…K4 (len 208)). src/tools/payment-mcp-tools.js: contains a hardcoded Stripe test secret key (sk_t…O0 (len 107)) — test-mode credential, low severity. Reads secrets from the environment (e.g. src/app-store-server.js) — the recommended intake shape.

• Permission scope

  fail15% of grade

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

  HIGH: shell/exec capability AND network egress together — download-and-execute risk (cli.js: imports child_process and calls exec/spawn; src/services/auth-service.js: outbound HTTP/socket call). HIGH: shell/exec capability AND destructive filesystem writes together (cli.js: imports child_process and calls exec/spawn; src/cli/auth-cli.js: destructive/writing fs.* call

attacker-controlled.

• Version behavior

  unscannable10% of grade

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

  no prior version to diff (first sight of io.github.ruvnet/[email protected]); version-drift / rug-pull cannot be evaluated. Cold-start risk is covered by point-in-time checks (injection_surface, supply_chain, credential_hygiene), not here.

• Transport config

  warn10% of grade

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