AI employee operating system — persistent memory, task management, and multi-agent coordination for Claude Code.

AI Security Review

scanned 1d ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. Installation mutates the global Claude Code control surface without a user setup command. It installs skills and, after setup is detected, adds an MCP server and broad event hooks.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

npm postinstall during package installation

Impact

Package code can run in future Claude Code sessions and observe or influence broad tool-event workflows.

Mechanism

automatic global Claude Code skill, MCP, and hook registration

Policy narrative

Installing the package automatically runs its installer. That path copies package-owned skills into the global Claude directory; once setup state is present, it rewrites global MCP configuration and registers commands for broad Claude Code lifecycle events, including tool use. This is unconsented postinstall mutation of a foreign AI-agent control surface, creating persistent execution within later Claude sessions.

Rationale

The package’s postinstall silently modifies global Claude Code configuration and installs broad lifecycle hooks, meeting the firewall block policy for unconsented AI-agent control-surface mutation. No remote payload was needed to establish this concrete persistent control path.
