@cloop/runner@0.3.15
Make your machine and your agents Cloop runners: device login, the runner daemon, the Cloop MCP server, and Claude Code hooks.
AI Security Review
scanned 13d ago · by lpm-firewall-aiThe runtime paths forward a saved service token to the selected mesh URL, and the URL can be overridden without an allowlist. Because the transfer requires running the service with that configuration and the default endpoint is package-aligned, this supports a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
Run the workstation runner or MCP server with a token available and CLOOP_MESH_URL configured.
Impact
The configured endpoint receives the device token and may be able to use it to authenticate as the runner.
Mechanism
The service passes the saved token to MeshSocket, which supplies it as a WebSocket subprotocol to the selected URL; the client places subprotocols in the request header.
AI rationale
The runtime paths forward a saved service token to the selected mesh URL, and the URL can be overridden without an allowlist. Because the transfer requires running the service with that configuration and the default endpoint is package-aligned, this supports a warning rather than a publish block.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The token loader returns a saved credential token or CLOOP_TOKEN, while the mesh URL can be overridden with CLOOP_MESH_URL without destination validation.
- Both the workstation runner and MCP server pass the token and selected mesh URL to MeshSocket when starting a connection.
- MeshSocket supplies the token as a WebSocket subprotocol, and the ws implementation places supplied subprotocols in the request header.
- The runner reads metadata from other Claude project sessions and can include it in mesh presence; this is a separate presence feature from the credential transfer.
Evidence against
- The manifest describes a Cloop runner and declares no install lifecycle hooks; the default mesh destination is Cloop's service.
- The credential exposure requires running the service with a configured mesh URL override; this is a warning about endpoint binding, not evidence of covert default exfiltration.
