AI Security Review

scanned 2d 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 runs the `signaliz-mcp` bin without `test` or `tools`.
Impact
Can enable an MCP server in Claude Desktop, Cursor, or a local generic MCP config after user invocation.
Mechanism
Explicit MCP configuration write with floating npx server reference.
Rationale
Source inspection confirms a real, explicit-user-command MCP configuration write and floating remote server reference. No concrete covert execution, exfiltration, or install-time mutation is present.

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` default command writes MCP client configuration.
  • It detects Claude Desktop or Cursor config paths and inserts `mcpServers.signaliz`.
  • Configured server runs `npx -y @signaliz/mcp-server@latest`, a floating remote package.
  • The CLI prompts for or reads `SIGNALIZ_API_KEY` before writing configuration.
Evidence against
  • `package.json` has only `prepublishOnly`; no install-time lifecycle hook.
  • Configuration mutation occurs only when the user runs the `signaliz-mcp` bin.
  • `dist/index.js` network requests are SDK API calls to `api.signaliz.com`.
  • No child-process execution, eval, payload download, or unrelated credential harvesting was found.
