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

  warn25% of grade

  Package provenance: namespace verification, repo linkage, maintainer count, account age, postinstall scripts, typosquat distance.

  dependency "@opentelemetry/api" is edit-distance 2 from popular package "pg" (typosquat candidate)

• Credential hygiene

  warn15% of grade

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

  .env.example: contains a hardcoded Slack token (xoxb…re (len 20)) — in an example/sample file; verify it is not a real key. Reads secrets from the environment (e.g. src/utils/aegis-vault.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 (src/utils/baseline-manager.js: imports child_process and calls exec/spawn; src/utils/codebase-analyzer.js: outbound HTTP/socket call). has both shell/exec and destructive filesystem writes (src/utils/baseline-manager.js: imports child_process and calls exec/spawn; src/utils/aegis-vault.js: destructive/writing fs.* call (write/unlink/rm/chmod/rename)). discloses shell/exec capability: 7 files (src/utils/baseline-manager.js, src/cli/chrome-launcher.js, src/orchestration/dispatcher.js, +4 more) discloses dynamic code execution: src/utils/security-analyzer.js: uses eval(…) discloses broad/destructive filesystem access: 21 files (src/utils/aegis-vault.js, src/utils/baseline-manager.js, src/utils/diff.js, +18 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 9.9.0 (major bump): new capability primitive(s) in source: child_process, dynamic-eval, fs-write, http-client; new hardcoded outbound host/BCC destination(s): ..., 127.0.0.1, api.example.com, api.figma.com, api.github.com, api.slack.com, argus-qa.com, example.com, example.comlogin, fonts.googleapis.com, fonts.gstatic.com, github.com, host, staging.example.com, staging.yourapp.com, www.figma.com, www.google.com, your-server.com.

• 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 (Datadog) — disclosure, verify opt-in; manifest/source references phone-home behavior — disclosure
