AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest has no install lifecycle hooks, and the flagged editor configuration and persistence behavior requires an explicit CLI command. Antigravity wiring writes artifacts but neither loads the launchd agent nor configures it to run at load.
Static reason
No blocking static signals were detected.
Trigger
A user invokes setup, install, or channel; the MCP server starts when its configured CLI entry is run.
Impact
No unauthorized install-time or default persistence behavior was identified.
Mechanism
Setup and install configure the user's editor integrations. Antigravity wiring creates a script and launchd plist but does not activate the agent; the plist does not run at load.
AI rationale
The manifest has no install lifecycle hooks, and the flagged editor configuration and persistence behavior requires an explicit CLI command. Antigravity wiring writes artifacts but neither loads the launchd agent nor configures it to run at load.

Decision evidence
public snapshotAI called this Clean at 96.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest declares a CLI entry point and no lifecycle scripts.
- The dispatcher runs setup and install only when those commands are invoked; install explicitly calls the editor installer.
- Antigravity wiring writes a script and launchd plist but does not load the agent; its plist sets RunAtLoad to false.
- The default server resolves its token and service base URL when runServer is called.
