API Spector private runner: monitor internal/local APIs the cloud cannot reach, with no inbound connections.
AI Security Review
scanned 7h ago · by lpm-firewall-aiThe bundled entry polls only the user-configured API Spector service and returns results for its assigned checks. Its script execution and network activity match the package's stated monitoring purpose, and the scanner's redirect and payload-loader leads were not supported by the reviewed application code.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
The user starts the CLI with APP_URL and an agent or runtime token configured.
Impact
Observed network and script execution support the documented monitoring feature; no unrelated credential collection or fixed unofficial gateway was identified.
Mechanism
It polls the configured service for due checks, runs those checks, and posts their results back to the configured service.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest exposes dist/index.cjs as both the CLI and the package main, with no lifecycle scripts present.
- The README says APP_URL and AGENT_TOKEN are required and describes the agent as polling API Spector Cloud for due checks and returning results.
- Runtime requests use the configured APP_URL and environment-provided AGENT_TOKEN or RUNTIME_TOKEN.
- The runner polls the configured service's due-feed endpoint and posts monitor results to that same service.
- The runner executes check scripts in a sandbox with a timeout; the README describes pre/post scripts as part of the API-check engine.
