AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a first-party, user-invoked agent extension that writes hooks, MCP configuration, and permission rules, so it warrants a warning. No registry lifecycle hook or concrete malicious behavior was found.
Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the setup, install, or repair CLI command; configured editor hooks then run during editor events.
Impact
It expands the configured AI-agent control surface and enables automated session-derived data uploads to the vendor service.
Mechanism
AI-editor MCP and hook configuration with authenticated digest upload.
AI rationale
This is a first-party, user-invoked agent extension that writes hooks, MCP configuration, and permission rules, so it warrants a warning. No registry lifecycle hook or concrete malicious behavior was found.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit setup and install commands invoke code that wires AI-editor integrations.
- The Claude adapter adds a Stop hook and extends its MCP tool permission allowlist.
- The Codex adapter writes an MCP server configuration and a Stop hook that runs this package through npx.
- The capture path sends derived session data to agnoclast.com with the configured bearer token.
- The Antigravity adapter writes a shell script and LaunchAgent plist, though it does not activate the agent.
Evidence against
- package.json has no preinstall, install, postinstall, or other automatic lifecycle hook.
- The integration is activated only through user-invoked CLI commands.
- Capture code removes the transcript field before serializing its upload.
- No obfuscated payload, arbitrary remote code execution, credential harvesting, or destructive behavior was found.
