AI Security Review

scanned 10d ago · by lpm-firewall-ai

The automatic postinstall setup enables guarded, first-party macOS service persistence, so this warrants a warning. The inspected source does not establish malicious behavior or unconsented changes to unrelated AI-agent configuration.

Static reason

One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review

Trigger

A normal npm install on macOS when the postinstall opt-out is unset and the daemon-disable marker is absent.

Impact

This creates user-level background service persistence for the package’s own daemon; no separate credential theft or unrelated agent configuration change was established.

Mechanism

The hook writes the user-level LaunchAgent plist and bootstraps it to run trace-mcp serve-http through the package launcher.

AI rationale

Evidence

package.jsonscripts/postinstall-control-plane.mjs~/Library/LaunchAgents/com.trace-mcp.server.plist~/.trace/launcher.env~/.trace/bin/trace

Decision evidence

public snapshot

AI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json runs the native preflight, app updater, and control-plane setup in its npm postinstall chain.
The control-plane script writes this package’s launcher files and targets its own user-level macOS LaunchAgent.
On macOS, the hook creates and bootstraps the LaunchAgent unless the daemon-disable marker is present; environment, CI, development, and ephemeral-install guards limit activation.
The plist runs trace-mcp serve-http at load and keeps it active, creating user-level background persistence.
The flagged Claude and Codex locations are path declarations in the bundles; the associated benchmark scripts read local project instructions and session logs.

Evidence against

This is a package-owned local service with explicit opt-out and environment guards; the inspected agent-path references do not establish changes to other agent configurations.
