API Spector private runner: monitor internal/local APIs the cloud cannot reach, with no inbound connections.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThere is no install hook, self-dependency, or hardcoded exfiltration target. The agent only runs when invoked and authenticates to the caller-supplied API Spector host, which matches the private-runner product.
Static reason
One or more suspicious static signals were detected.
Trigger
A person runs the api-spector-agent binary with APP_URL and AGENT_TOKEN or RUNTIME_TOKEN set.
Impact
Network access and script execution stay inside the monitoring job the operator configured. No unsolicited credential export, persistence, or install mutation was found.
Mechanism
The process polls that base URL for due checks, executes them with the bundled engine, and posts results back to the same host.
AI rationale
There is no install hook, self-dependency, or hardcoded exfiltration target. The agent only runs when invoked and authenticates to the caller-supplied API Spector host, which matches the private-runner product.
Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json exposes only a CLI bin and main entry at dist/index.cjs and declares no install lifecycle scripts or dependencies.
- The runner reads APP_URL, AGENT_TOKEN, and RUNTIME_TOKEN from the environment and exits unless a cloud base URL and a token are set.
- Due monitors are fetched from and results posted to that caller-supplied APP_URL; pre/post scripts run in a vm context that does not receive require or process.
Evidence against
- The bundled test engine can resolve named secret refs from the environment or a local Vault token file, and a bundled Electron helper can spawn a download, but both run only when a user-started check asks for them.
