Core runtime for Whalent Agent
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe manifest has no install hooks, and the package description is consistent with an agent runtime. However, the obfuscated published MCP bundle prevents reliable verification of all runtime behavior, so the unresolved risk warrants a warning rather than a clean verdict or a claim of confirmed attack behavior.
Static reason
One or more suspicious static signals were detected.
Trigger
Using the package’s executable or MCP runtime.
Impact
No specific harmful effect was confirmed; the unresolved behavior leaves residual risk.
Mechanism
Encoded names and string-table lookups obscure runtime code and make its behavior difficult to verify by static inspection.
AI rationale
The manifest has no install hooks, and the package description is consistent with an agent runtime. However, the obfuscated published MCP bundle prevents reliable verification of all runtime behavior, so the unresolved risk warrants a warning rather than a clean verdict or a claim of confirmed attack behavior.
Evidence
dist/mcp.cjs
Decision evidence
public snapshotAI called this Suspicious at 74.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- package.json points the command-line entrypoint at dist/index.cjs and declares no lifecycle scripts.
- dist/mcp.cjs uses a large encoded string table and its embedded metadata lists javascript-obfuscator, leaving runtime behavior difficult to verify from the published source.
- README.md describes the package as Whalent Agent’s core runtime, launched by its wrapper.
Evidence against
- The manifest has no preinstall, install, or postinstall hook.
- The README and manifest describe a package-aligned agent runtime and its executable entrypoint.
