AI Security Review
scanned 2d ago · by lpm-firewall-aiSource inspection confirms an automatic postinstall path that installs skills and may install and register the package’s MCP server in user-level agent configuration. This is a guarded first-party extension lifecycle risk, so warn rather than block.
Static reason
High-risk behavior combination matched malicious policy.; source fingerprint signature matched known malicious package; routed for review
Trigger
Installing the package when npm runs its postinstall hook.
Impact
User-level agent skill directories and MCP configuration may be changed without a separate setup command.
Mechanism
The hook installs skills for resolved user targets, then manages a global WoWok MCP server and registers it in client configuration unless the MCP opt-out is set.
AI rationale
Source inspection confirms an automatic postinstall path that installs skills and may install and register the package’s MCP server in user-level agent configuration. This is a guarded first-party extension lifecycle risk, so warn rather than block.
Evidence
package.jsonscripts/install.jsdist/installer.jsdist/targets.js
Decision evidence
public snapshotAI called this Suspicious at 88.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The postinstall hook runs scripts/install.js, which invokes the shared lifecycle installer.
- The postinstall flow installs skills for detected user targets and manages MCP setup unless an environment flag disables it.
- MCP setup can run a global npm install of the WoWok server package.
- The installer registers a named WoWok MCP entry in client configuration.
- The target table includes a cross-client skills directory.
Evidence against
- The inspected configuration write adds a named WoWok server entry; the cited source does not show broad settings changes or credential collection.
