MMI workflow skills and org gates delivery.
AI Security Review
scanned 6d ago · by lpm-firewall-aiSource inspection found no lifecycle hooks in package.json and no confirmed attack behavior. The credential transfer is part of a Hub session exchange, and the flagged agent-configuration path is used during plugin repair.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
A user invokes the CLI command that needs a Hub session or runs the explicit plugin repair flow.
Impact
No concrete malicious effect was established from these behaviors.
Mechanism
The CLI sends a GitHub token to the configured MMI Hub session endpoint; the marketplace repair flow reads and restores relevant settings around repair steps.
AI rationale
Source inspection found no lifecycle hooks in package.json and no confirmed attack behavior. The credential transfer is part of a Hub session exchange, and the flagged agent-configuration path is used during plugin repair.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json declares the package identity and ships the CLI; it defines no lifecycle hooks.
- The CLI’s default Hub endpoint is package-aligned with the MMI Hub service.
- The CLI sends a GitHub token to that Hub’s session endpoint as an authentication exchange.
- The agent-integration location identifies Claude’s marketplace settings file; the heal flow reads its pins, runs plugin repair steps, then restores those pins.
- The launcher requires the sibling CLI bundle only when invoked; its version-only path prints the package version.
