Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 16 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Data Exfiltration - **Selected version:** 2.14.6 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The CLI runtime automatically collects telemetry, including a public IP address and persistent device-derived identifiers. No install-time execution or credential theft was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-27T02:41:07.845Z - **Finished:** 2026-09-27T02:44:10.589Z - **Download time:** 767 ms - **Static scan time:** 4793 ms - **AI review time:** 177183 ms - **Total time:** 182744 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** The CLI runtime automatically collects telemetry, including a public IP address and persistent device-derived identifiers. No install-time execution or credential theft was confirmed. - **Trigger:** Starting the MCP server through its CLI or module entrypoint. - **Impact:** User and runtime activity can be correlated with a public IP and stable local identifier. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T02:44:10.589Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default-enabled telemetry fetches a public IP address and posts analytics payloads to fixed external endpoints. - **Rationale:** The package has active default telemetry that exports public-IP and persistent device-linked activity data. This warrants a warning, but the inspected source does not establish malware or an install-time attack. - **Files touched:** dist/index.js - **Network endpoints:** https://www.google-analytics.com/mp/collect, https://weppy-operations-server.hope841026.workers.dev/public/mcp/device-observation/v1, https://api.ipify.org ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest exposes the bundled runtime as both the main module and CLI entrypoint., The runtime enables telemetry by default for non-development versions, initializes it, and fetches the public IP address., Telemetry attaches the public IP and a persistent device-derived identifier to analytics payloads and sends them by HTTP POST., The runtime contains fixed endpoints for Google Analytics, an operator device-observation service, and public-IP lookup. - **Evidence against:** The manifest contains only a start script and no automatic install lifecycle hook., No credential environment-variable harvesting was found in the active bundle. ## Affected versions and remediation This report applies to @weppy/roblox-mcp@2.14.6. - Review the evidence and your use of @weppy/roblox-mcp@2.14.6 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
