AI Security Review

scanned 17d ago · by lpm-firewall-ai

Source supports a warning for automatic first-party agent extension setup and conditional credential exposure. Namespace safeguards and explicit maintenance commands do not support the scanner's malicious classification.

Static reason

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

Trigger

A local npm installation; remote synchronization additionally requires an MCP URL and access token.

Impact

Installed skills can influence agent behavior; an incorrectly configured MCP destination can receive the service access token.

Mechanism

Postinstall copies packaged skills and optionally fetches authenticated MCP resources for installation into a separate managed namespace.

AI rationale

Evidence

package.jsoncli/postinstall.mjscli/install-agent-skills.mjscli/install-mcp-skills.mjscli/mcp-platform-skills.mjs.agents/skills/command-center.agents/skills/ms-command-center

Decision evidence

public snapshot

AI called this Suspicious at 93.0% confidence as Dangerous Capability with medium false-positive risk.

Evidence for warning

package.json automatically runs cli/postinstall.mjs, which invokes the agent skill installer.
The local installer copies skills into .agents/skills/command-center and replaces entries within that namespace.
Configured MCP skill synchronization also runs during postinstall unless disabled, installing into .agents/skills/ms-command-center.
MCP requests can send MAINSEQUENCE_ACCESS_TOKEN to an operator-configured HTTP(S) URL without a destination allowlist.

Evidence against

Skill installation is confined to package-owned namespaces with path and symbolic-link safeguards; legacy cleanup checks ownership records.
The manifest has no runtime self-dependency. SDK maintenance commands are explicit CLI operations rather than postinstall actions.
No concrete covert exfiltration, remote code execution, or broad foreign agent configuration mutation was established.
