@whalent/agent-core@0.3.481
Core runtime for Whalent Agent
AI Security Review
scanned 22d ago · by lpm-firewall-aiThe inspected agent configuration capability supports a behavior-specific warning, not a malware block. Static inspection established no block-eligible attack chain.
Static reason
One or more suspicious static signals were detected.
Trigger
Invocation of runtime skill installation or MCP registration tools.
Impact
Requested changes can alter future agent tools and instructions.
Mechanism
Tool arguments select commands and settings that are written into agent configuration; skill files can target home-directory platform skill locations.
AI rationale
The inspected agent configuration capability supports a behavior-specific warning, not a malware block. Static inspection established no block-eligible attack chain.
Evidence
dist/mcp.cjs.claude.json
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json exposes the runtime CLI and declares no npm lifecycle hooks or runtime self-dependency.
- dist/mcp.cjs handles tool requests that register caller-supplied commands, arguments and environment in agent configuration.
- dist/mcp.cjs writes MCP server entries into .claude.json and supports other agent configuration formats.
- Skill installation supports machine-wide agent skill directories.
Evidence against
- No concrete covert exfiltration or malicious install behavior was established.
- Configuration changes occur in runtime tool handlers; inspected source does not establish automatic npm installation mutation.
