arcy.js@0.2.10
ARCY, the universal JavaScript utility for embedding an AI agent that talks to, learns from, and acts on behalf of your users.
AI Security Review
scanned 20d ago · by lpm-firewall-aiSource inspection found no malicious behavior. The network signals correspond to product API calls, configured workflow routes, and a local CSP warning; the manifest has no install-time hook.
Static reason
One or more suspicious static signals were detected.
Trigger
A caller initializes the widget or runs a workflow route.
Impact
No confirmed unauthorized disclosure or account action was found; configured workflow requests can include browser credentials as part of that integration.
Mechanism
Workflow route data is sent to its configured target; product session calls use the ARCY API. The CSP callback only warns about relevant policy violations.
AI rationale
Source inspection found no malicious behavior. The network signals correspond to product API calls, configured workflow routes, and a local CSP warning; the manifest has no install-time hook.

Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest points to the inspected runtime bundles and has a prepublishOnly build check, not an install hook.
- Workflow requests allow same-origin targets or an explicitly configured origin; the request uses that route’s method and may include browser credentials.
- Chat session calls send a bearer token through apiBase and omit ambient browser credentials.
- The CSP callback checks violations and displays a warning; it does not send a report.
