@whalent/agent@0.3.495
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 19d ago · by lpm-firewall-aiInspected source supports a warning for runtime agent configuration capability, with no evidence establishing an unconsented npm install attack. Obfuscation and limited verification of the oversized core reduce confidence in broader conclusions.
Static reason
One or more suspicious static signals were detected.
Trigger
CLI runtime activation followed by an MCP tool request to install a skill or register or remove a server.
Impact
Invoked operations can alter instructions and tools available to an agent; this warrants a capability warning rather than a malware block.
Mechanism
Tool handlers download skill files and write agent directories, or modify MCP server configuration using request-supplied commands and arguments.
AI rationale
Inspected source supports a warning for runtime agent configuration capability, with no evidence establishing an unconsented npm install attack. Obfuscation and limited verification of the oversized core reduce confidence in broader conclusions.
Evidence
dist/core.cjsdist/mcp.cjs.cursorconfig.toml
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- dist/core.cjs routes MCP tool requests to operations that install downloaded skills and register or remove MCP servers.
- dist/mcp.cjs resolves skill destinations under workspace or home agent directories and writes supplied files.
- dist/mcp.cjs can update MCP server entries in config.toml.
- package.json has no npm install hooks or runtime self-dependency; dist/index.cjs activates the core through CLI execution.
Evidence against
- No concrete covert credential export or malicious install-time mutation was established.
- Obfuscated bundles limit inspection; dist/core.cjs exceeded the citation tool's verification size limit.
