AI Security Review
scanned 10d ago · by lpm-firewall-aiThe postinstall hook automatically modifies AI client setup by installing skills and registering the package’s MCP server. The behavior is aligned with the package’s extension setup, so it warrants a warning rather than a publish 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, unless MCP management is disabled by environment variable.
Impact
AI clients may load the WoWok MCP server and installed skills after setup. The inspected source does not establish a separate malicious action.
Mechanism
The hook installs skills and, by default, installs or updates @wowok/agent-mcp and registers its launcher in detected client configuration files.
AI rationale
The postinstall hook automatically modifies AI client setup by installing skills and registering the package’s MCP server. The behavior is aligned with the package’s extension setup, so it warrants a warning rather than a publish block.
Evidence

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs scripts/install.js automatically through postinstall.
- The lifecycle hook proceeds only for postinstall and installs skills into user-level client roots.
- Unless disabled by an environment variable, postinstall installs or updates the vendor’s @wowok/agent-mcp package and registers it in client configs.
- Registration writes a WoWok MCP entry using its launcher command and arguments.
- Default registration skips clients with no sign of being installed on the machine.
