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. src/tools/engine/capture.ts) — 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 (scripts/check-deps.js: imports child_process and calls exec/spawn; src/tools/engine/editing.ts: outbound HTTP/socket call). HIGH: shell/exec capability AND destructive filesystem writes together (scripts/check-deps.js: imports child_process and calls exec/spawn; src/tools/engine/audio-mixer.ts: path traversal ('../') combined with file access). discloses shell/exec capability: scripts/check-deps.js: imports child_process and calls exec/spawn discloses shell/exec capability: src/lib/ffmpeg-bin.ts: imports child_process and calls exec/spawn discloses shell/exec capability: src/lib/ffmpeg-run.test.ts: imports child_process discloses shell/exec capability: src/lib/ffmpeg-run.ts: imports child_process and calls exec/spawn discloses broad/destructive filesystem access: src/tools/engine/audio-mixer.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/audio.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/beat-sync.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/beat-sync.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/capture.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/capture.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/chroma-key.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/concat.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/editing.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/editing.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/encoder.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/encoder.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/lut-presets.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/narrated-video.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/narrated-video.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/smart-screenshot.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/social-format.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/lib/temp-dir.test.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/lib/temp-dir.test.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/template-renderer.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/template-renderer.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/templates.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/text-animations.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/text-overlay.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/handlers/tts.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/tts.ts: destructive/writing fs.* call (write/unlink/rm/chmod/rename) discloses broad/destructive filesystem access: src/tools/engine/tts.ts: path traversal ('../') combined with file access discloses broad/destructive filesystem access: src/tools/engine/voice-effects.ts: 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.studiomeyer/[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.

  sends telemetry to third-party SDK (amplitude) — disclosure, verify opt-in
