@whalent/agent@0.3.479
Stable wrapper for Whalent Agent core runtime
AI Security Review
scanned 23d ago · by lpm-firewall-aiInspected source establishes runtime agent configuration mutation, which warrants a warning under the supplied policy. It does not establish malicious intent or an unconsented npm installation attack.
Static reason
One or more suspicious static signals were detected.
Trigger
A caller invokes a management tool on the running MCP server.
Impact
Requests can change agent behavior and configure commands that an agent may subsequently launch.
Mechanism
Tool arguments select skill installation or removal and MCP server registration or removal; registration persists command settings in provider configuration.
AI rationale
Inspected source establishes runtime agent configuration mutation, which warrants a warning under the supplied policy. It does not establish malicious intent or an unconsented npm installation attack.
Evidence
dist/mcp.cjs.claude.jsonconfig.toml.cursor
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package exposes dist/index.cjs as its CLI and has no preinstall, install, or postinstall hook.
- The MCP request handler dispatches caller-selected tools and arguments to the runtime tool handler.
- The MCP management tool accepts commands, arguments, and environment settings and registers servers in agent configuration.
- Claude server registration writes .claude.json; skill management also installs downloaded files into provider-specific directories.
- The flagged location selects provider directories, including .cursor.
Evidence against
- No concrete covert exfiltration or malicious installation chain was established.
- Configuration changes are activated through runtime tool requests rather than npm installation.
