linkshell-cli@0.5.41
Remote terminal bridge for Claude Code / Codex / Gemini / Copilot — control from your phone
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package is not shown to be malware, but it exposes a dangerous remote AI-agent capability with a permission-bypassing fallback. Its install hook is limited to node-pty permission repair, so blocking as malicious is not supported by the inspected source.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs linkshell start and connects a remote client that submits terminal input or Claude agent prompts.
Impact
A party able to use the paired remote session could execute shell commands through the terminal or Claude tools and receive terminal output.
Mechanism
Remote terminal relay and permission-bypassing Claude agent fallback.
AI rationale
The package is not shown to be malware, but it exposes a dangerous remote AI-agent capability with a permission-bypassing fallback. Its install hook is limited to node-pty permission repair, so blocking as malicious is not supported by the inspected source.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The install hook automatically changes permissions on node-pty helper binaries.
- A started bridge forwards gateway terminal input to a local PTY and sends terminal output back over its socket.
- The default Claude fallback configures bypassed agent permissions; its code states remotely submitted prompts can run shell tools without confirmation.
- The login command receives OAuth tokens through a loopback callback and uses them for authenticated service requests.
- The explicit upgrade command runs a global npm installation of the latest package.
Evidence against
- The postinstall script only adjusts executable bits for known node-pty helper paths; it has no network, shell, or payload behavior.
- No runtime dependency refers to linkshell-cli itself.
- The risky bridge and agent behavior require the user to run the CLI; it is not activated at installation.
- The agent fallback has a documented environment-variable guard that refuses it when permission enforcement is required.
- No source evidence shows secret harvesting, hidden exfiltration, destructive actions, or foreign agent-config installation.
