AI Security Review
scanned 4d ago · by lpm-firewall-aiThe manifest declares no install hook, and inspected excerpts do not establish concrete malicious behavior. The substantial obfuscation in an executable bundle leaves a real unresolved risk, so this warrants a warning rather than a clean verdict or block.
Static reason
One or more suspicious static signals were detected.
Trigger
Running the package entrypoint or MCP executable.
Impact
The unresolved behavior prevents a clean assessment; no specific harmful effect was established.
Mechanism
The MCP bundle uses obfuscated code that limits static verification.
AI rationale
The manifest declares no install hook, and inspected excerpts do not establish concrete malicious behavior. The substantial obfuscation in an executable bundle leaves a real unresolved risk, so this warrants a warning rather than a clean verdict or block.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 75.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The manifest points the package entrypoint and executable command at dist/index.cjs and declares no lifecycle scripts.
- The dist/mcp.cjs executable begins with heavily obfuscated code, leaving its behavior difficult to verify from static inspection.
- The MCP bundle includes an interface for handling tool requests, consistent with runtime functionality, but the inspected excerpts do not establish an attack.
Evidence against
- No install lifecycle hook is declared in package.json.
- The inspected source did not establish credential theft, unauthorized account actions, or another concrete attack.
