@whalent/agent-core@0.3.486
Core runtime for Whalent Agent
AI Security Review
scanned 21d ago · by lpm-firewall-aiSource confirms caller-invoked agent configuration mutation, which the supplied policy classifies as warning-only. Obfuscation limits broader assurance but does not independently prove malicious intent.
Static reason
One or more suspicious static signals were detected.
Trigger
A caller invokes whalent_manage_mcp with the register action.
Impact
Registered commands can run when the agent subsequently starts the configured MCP server.
Mechanism
The handler forwards server settings to configuration helpers, which update agent MCP configuration.
AI rationale
Source confirms caller-invoked agent configuration mutation, which the supplied policy classifies as warning-only. Obfuscation limits broader assurance but does not independently prove malicious intent.
Evidence
dist/mcp.cjsconfig.toml
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest has no install lifecycle hooks or runtime self-dependency.
- The MCP request handler dispatches caller-selected tools.
- The MCP registration tool accepts server commands, arguments, and environment settings and passes them to agent configuration helpers.
- The Codex helper updates config.toml with the registered MCP server.
Evidence against
- No covert exfiltration or malicious install-time mutation was established.
- Inspected dynamic code generation belongs to bundled schema validation; string decoding alone does not establish a hidden executable payload.
