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 grade

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

  tool "emem_recall" description: bare 'IMPORTANT:' prose in a description (tag form is high-confidence; prose is warn). tool "emem_memory_token" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes. tool "emem_memory_token_resolve" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes. tool "emem_verify_receipt" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes. tool "emem_guard_verdict" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes. tool "emem_echo_verify" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes. tool "emem_memory_bundle" description: off-vendor URL in a description (emem.dev); capability text should not name where data goes.

• 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 "emem_entity_link" has a secret-shaped input parameter "entity_token" — 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

  pass10% of grade

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

  vs prior 2.2.0 (minor bump): tool "emem_tools" description changed (wording only, no injection pattern); tool "emem_ask" gained input property(ies): model. Low-severity drift (informational; consistent with the version bump).

• Transport config

  pass10% of grade

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

  remote endpoint "https://emem.dev/mcp" uses TLS (https); remote endpoint uses OAuth (strongest auth mode)
