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

  warn15% of grade

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

  fixer.js: assigns a literal to TOKEN (pref…ed (len 26)) — non-provider secret literal; prefer environment intake. payload.js: assigns a literal to api_key (supe…23 (len 19)) — non-provider secret literal; prefer environment intake. Reads secrets from the environment (e.g. review.js) — the recommended intake shape.

• Permission scope

  warn15% of grade

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

  has both shell/exec and network egress — capable of download-and-run, though no such path was observed (cli.js: imports child_process and calls exec/spawn; watcher.js: outbound HTTP/socket call). discloses shell/exec capability: 5 files (cli.js, fixer.js, llmfix.js, +2 more) 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 0.5.5 (patch bump): new capability primitive(s) in source: child_process, http-client; new hardcoded outbound host/BCC destination(s): api.anthropic.com, api.github.com, api.openai.com, api.slack.com, developers.cloudflare.com, docs.aws.amazon.com, github.blog, github.com, mendapi.com, shopify.dev.

• Transport config

  warn10% of grade

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

  manifest/source references tracking behavior — disclosure
