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

  pass15% of grade

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

  Reads secrets from the environment (e.g. store/api.js) — the recommended intake shape. PASS = no static red flag; static analysis cannot prove the code honors env-based secret handling at runtime.

• 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 (tools/context.js: imports child_process and calls exec/spawn; tools/board.js: outbound HTTP/socket call). HIGH: shell/exec capability AND destructive filesystem writes together (tools/context.js: imports child_process and calls exec/spawn; tools/_actions.js: path traversal ('../') combined with file access). discloses shell/exec capability: tools/context.js: imports child_process and calls exec/spawn discloses shell/exec capability: notify.js: imports child_process and calls exec/spawn discloses shell/exec capability: tools/update.js: imports child_process and calls exec/spawn discloses broad/destructive filesystem access: tools/_actions.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: store/api.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/board.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/bye.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: config.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: tools/consent.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/context.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/dm.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/doctor.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/echo.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/forget.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/game.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/inbox.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/_shared/index.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/init.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/invite.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: store/local.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: store/local.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: memory.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: notify.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: tools/open.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/patterns.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/ping.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/react.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/recall.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/remember.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/start.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/status.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/submit.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/summarize.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: tools/summarize.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/test.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/update.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/who.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/x-mentions.js: path traversal ('../') combined with file access discloses broad/destructive filesystem access: tools/x-reply.js: path traversal ('../') combined with file access Capability DISCLOSURE, not a verdict: static analysis sees the primitive is present and reachable, not whether its use is 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.brightseth/[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.

  manifest/source references tracking behavior — disclosure
