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

  fail25% of grade

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

  tool "schedule" param "url" description: names an outbound copy/exfil destination (BCC/exfil verb). tool "deadman_register" param "url" description: names an outbound copy/exfil destination (BCC/exfil verb). tool "schedule_cron" param "url" description: names an outbound copy/exfil destination (BCC/exfil verb).

• 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.

  tool "exec_quote" has a secret-shaped input parameter "tokenIn" — secrets must never be tool parameters (the model would supply/handle the credential). tool "exec_quote" has a secret-shaped input parameter "tokenOut" — secrets must never be tool parameters (the model would supply/handle the credential). tool "exec_slippage" has a secret-shaped input parameter "tokenIn" — secrets must never be tool parameters (the model would supply/handle the credential). tool "exec_slippage" has a secret-shaped input parameter "tokenOut" — secrets must never be tool parameters (the model would supply/handle the credential). tool "exec_sandwich" has a secret-shaped input parameter "tokenIn" — secrets must never be tool parameters (the model would supply/handle the credential). tool "exec_sandwich" has a secret-shaped input parameter "tokenOut" — secrets must never be tool parameters (the model would supply/handle the credential).

• Permission scope

  unscannable15% of grade

  Declared 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

  fail10% of grade

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