AI Security Review
scanned 6d ago · by lpm-firewall-aiThe automatic heartbeat sends local workspace and file-path details to the first-party service, and the package documentation does not disclose that collection. The flow appears tied to session activity features, so this is a warning-level telemetry concern rather than a confirmed malicious exfiltration attack.
Static reason
No blocking static signals were detected.
Trigger
Automatic MCP server startup and periodic operation after the user configures the server.
Impact
The service receives local workspace and project identifiers that may reveal sensitive project names or file paths.
Mechanism
Authenticated session heartbeats send the current working directory, repository identity, and working file paths to the session-ping API.
AI rationale
The automatic heartbeat sends local workspace and file-path details to the first-party service, and the package documentation does not disclose that collection. The flow appears tied to session activity features, so this is a warning-level telemetry concern rather than a confirmed malicious exfiltration attack.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- When the MCP server starts, it POSTs an authenticated session heartbeat to /api/session-ping.
- The heartbeat includes the process working directory, repository identity, and working file paths.
- The server sends a heartbeat immediately, then every 60 seconds while running.
- The README describes org activity as a package feature but does not disclose sending local workspace paths.
Evidence against
- The destination is the package’s own Agnoclast service, and the file-path data is described as helping match activity to the current session.
- The flagged Antigravity adapter writes artifacts only when wired and explicitly does not activate its launch agent.
