AI Security Review
scanned 4h ago · by lpm-firewall-aiReview 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 runs the `signaliz-mcp` bin command without `test` or `tools`.
Impact
The selected MCP client may launch `@signaliz/mcp-server@latest` with the supplied Signaliz API key after restart.
Mechanism
Explicit CLI MCP configuration mutation with an unpinned npx server command.
Rationale
Source inspection shows an explicit CLI-based AI-agent configuration capability, not malicious automatic behavior. Downgrade to warn because the setup installs an unpinned external MCP server and stores the supplied API key in client configuration.

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- `dist/mcp-config.mjs` CLI writes an MCP server entry into detected Claude, Cursor, or local MCP configuration.
- The setup entry invokes `npx -y @signaliz/mcp-server@latest`, delegating later execution to an unpinned external package.
- Setup reads `SIGNALIZ_API_KEY` or prompts for it, then persists it in the generated MCP configuration.
Evidence against
- `package.json` has only `prepublishOnly`; no install-time lifecycle hook executes the CLI.
- `dist/index.js` exports the SDK client and does not import or execute the config CLI.
- Network use is limited to the package-aligned `api.signaliz.com` API and token endpoints.
- No child-process calls, eval/vm usage, credential harvesting beyond the supplied API key, or destructive file operations were found.
