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

AI Security Review

scanned 1mo ago · by lpm-firewall-ai

LPM flags this version as an AI-agent control-surface risk. npm postinstall changes the user's global Claude Code control surface after the package has previously been set up. It installs skills, MCP configuration, event-triggered commands, and an allowlist for package MCP tools.

Static reason

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

Trigger

Installing or updating the package through npm after exe-os setup state exists.

Impact

Package code is configured to run on Claude Code session, prompt, tool, and lifecycle events, and its MCP tools are automatically allowed.

Mechanism

Postinstall registration of global Claude Code skills, hooks, MCP configuration, and permissions.

Policy narrative

The package's npm postinstall launches an installer automatically. Once its setup state exists, that installer edits global Claude Code configuration, registers its MCP server, adds commands that run package hooks for agent events, and adds package MCP tools to the permission allowlist. This is an unconsented install-time mutation of a broad AI-agent control surface, so later Claude Code activity can execute package-owned code without the user invoking the installer.

AI rationale

Automatic postinstall code modifies global Claude Code hooks, MCP configuration, and permissions. This concrete agent-control takeover meets the install-hook abuse blocking boundary.
