@whalent/agent@0.3.485
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 21d ago · by lpm-firewall-aiSource establishes explicit-request AI-agent configuration mutation, which warrants a warning under the supplied policy. No block-eligible attack was established.
Static reason
One or more suspicious static signals were detected.
Trigger
An explicit MCP registration tool request.
Impact
Registered commands can subsequently run as MCP servers under the configured provider.
Mechanism
The request supplies a command, arguments, and environment settings to provider configuration writers.
AI rationale
Source establishes explicit-request AI-agent configuration mutation, which warrants a warning under the supplied policy. No block-eligible attack was established.
Evidence
dist/mcp.cjs.claude.json
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 preinstall, install, or postinstall hook and no runtime self-dependency.
- MCP registration accepts caller-provided commands, arguments, and environment settings and modifies provider configuration.
- The Claude registration path saves MCP server changes to .claude.json.
- Configuration mutation is reached through an explicit MCP tool request.
Evidence against
- No concrete covert exfiltration or malicious install behavior was established.
- The flagged Function constructor appears in bundled AJV schema compilation; obfuscation alone does not establish a hidden payload.
