Cotal connector for Jcode: a host-mode mesh peer driven through Jcode's Harness API bridge.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe credential mirroring appears to support the Jcode integration, and I found no evidence that the credentials are exfiltrated to an unrelated service. However, it automatically exposes credentials from several other AI clients to the Jcode agent without a per-credential opt-in, which is a meaningful capability risk.
Static reason
One or more suspicious static signals were detected.
Trigger
Starting the package’s host-mode Jcode peer.
Impact
The Jcode agent may be able to act using accounts configured for other AI clients. The inspected source does not establish that credentials are transmitted to Cotal.
Mechanism
The host scans known Jcode and other AI-client credential locations and mirrors found files into a private Jcode home before launching the Harness API bridge.
AI rationale
The credential mirroring appears to support the Jcode integration, and I found no evidence that the credentials are exfiltrated to an unrelated service. However, it automatically exposes credentials from several other AI clients to the Jcode agent without a per-credential opt-in, which is a meaningful capability risk.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Unknown with medium false-positive risk.
Evidence for warning
- The package describes itself as a Cotal host-mode mesh peer driven through Jcode’s Harness API bridge.
- The credential inventory includes local Claude, Codex, Gemini, Cursor, and GitHub Copilot credential stores.
- When the host starts, it calls mirrorJcodeCredentials for the per-agent Jcode home.
- That function copies or links the discovered credential files into the Jcode home.
- The Jcode instance is launched with inheritLogins:false, but only after the connector has mirrored credentials.
- The manifest’s scripts list contains typecheck, test, build, and bundle; it declares no install lifecycle hook.
Evidence against
- The credential handling is part of the package’s Jcode host integration, and the files are prepared for a local Jcode instance.
- The inspected code does not establish that these credentials are sent to Cotal or another unrelated host.
- The Jcode launcher’s separate credential-inheritance option is disabled.
