AI Security Review
scanned 6d ago · by lpm-firewall-aiThe postinstall hook performs unprompted, project-local setup for this package’s own MCP server and skills, leaving a concrete agent-extension lifecycle risk. The inspected behavior supports a warning, while its package-owned, project-scoped integration does not establish a broader control-surface attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package as a local project dependency, unless setup is skipped by its environment guard.
Impact
MCP-enabled agents may discover and launch the package’s project server and load its skills without a separate setup command.
Mechanism
Project setup writes a server entry to the project’s MCP configuration and copies skills into agent discovery directories.
AI rationale
The postinstall hook performs unprompted, project-local setup for this package’s own MCP server and skills, leaving a concrete agent-extension lifecycle risk. The inspected behavior supports a warning, while its package-owned, project-scoped integration does not establish a broader control-surface attack.

Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The manifest runs a postinstall script, which invokes project setup during a local installation.
- The setup registers this package’s MCP command in the consumer project’s agent configuration and copies its skills into project agent directories.
- The integration is limited to a detected local project, can be skipped with an environment setting, and leaves an existing server entry alone.
- The registered command starts this project’s MCP server over standard input and output; the inspected setup does not establish credential theft or remote payload execution.
