AI Security Review

scanned 4h ago · by lpm-firewall-ai

Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior.

Static reason
No blocking static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User explicitly runs the `signaliz-mcp` bin command.
Impact
Changes an agent control surface and exposes the provided Signaliz API key to the registered server process.
Mechanism
Explicit MCP configuration write with floating `npx` server registration.
Rationale
Source inspection confirms an explicit CLI-based MCP setup capability with a floating downstream package reference. It is not malicious under the install-control policy, but it warrants a warning for agent-control-surface mutation.

Decision evidence

public snapshot
AI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
  • `dist/mcp-config.js` is a user-invoked `bin` and writes MCP configuration.
  • Setup targets Claude Desktop, Cursor, or `./.mcp/config.json`.
  • Written MCP entry runs `npx -y @signaliz/mcp-server@latest`, a floating remote package.
  • Setup copies `SIGNALIZ_API_KEY` into the MCP server environment.
Evidence against
  • `package.json` has no preinstall/install/postinstall hook.
  • Filesystem mutation occurs only when `signaliz-mcp` is explicitly executed.
  • No child-process execution, payload decoding, credential harvesting, or unrelated exfiltration was found.
  • SDK network calls are limited to `api.signaliz.com` service/auth endpoints.
