AI Security Review
scanned 6d ago · by lpm-firewall-aiThe manifest has no install hook, and the flagged configuration writes are reachable through explicit setup, install, or channel commands. Antigravity setup creates artifacts but does not activate its launch agent; the observed network use is consistent with the package’s Agnoclast MCP purpose.
Static reason
No blocking static signals were detected.
Trigger
Network requests occur when the MCP server or a relevant CLI command runs; editor configuration writes require an explicit setup or install command, and channel writes require an explicit channel choice.
Impact
No unauthorized credential transfer, automatic agent-control mutation, or activated persistence was identified.
Mechanism
Uses a token with the canonical Agnoclast service. Explicit setup commands write editor configuration; Antigravity setup writes a watcher script and plist but does not activate the launch agent.
AI rationale
The manifest has no install hook, and the flagged configuration writes are reachable through explicit setup, install, or channel commands. Antigravity setup creates artifacts but does not activate its launch agent; the observed network use is consistent with the package’s Agnoclast MCP purpose.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest declares no install lifecycle hooks; its scripts are release, promote, and rollback commands.
- Setup, cross-editor install, and channel changes run through explicit CLI subcommands.
- Channel configuration is written and existing entries are retagged only when a valid channel is supplied.
- The Antigravity adapter writes a sync script and launchd plist but explicitly does not load the agent.
- The MCP server requires a token and uses the package’s canonical Agnoclast service host.
