@memnexus-ai/mx-agent-cli@0.1.301
CLI for creating and managing AI agent teams
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe token deletion is an unrequested side effect of generated container setup, and the script does not check whether the credential is actually stale. The surrounding setup is consistent with the CLI's project-scaffolding purpose, so this warrants a warning rather than a malicious verdict.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
After a user runs `mx-agent new project`, the generated devcontainer runs its post-create script automatically.
Impact
A valid token may be removed, disrupting authenticated npm operations in the container.
Mechanism
The script unconditionally invokes `npm config delete` for the npm registry auth token; it does not verify that the token is stale.
AI rationale
The token deletion is an unrequested side effect of generated container setup, and the script does not check whether the credential is actually stale. The surrounding setup is consistent with the CLI's project-scaffolding purpose, so this warrants a warning rather than a malicious verdict.

Decision evidence
public snapshotAI called this Suspicious at 83.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The generated post-create script runs `npm config delete //registry.npmjs.org/:_authToken` without checking whether the token is stale.
- The generated devcontainer invokes that script automatically during container creation.
- The script is generated as part of the explicit `mx-agent new project` setup flow.
Evidence against
- The token removal is described as clearing stale npm auth that can block public package installs.
- Other setup actions install Node.js and Claude Code from their official hosts, consistent with the generated devcontainer's purpose.
