Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed attack was identified. Inspected runtime behavior supports Roblox integration, plugin setup, parser validation, licensing, and telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 87.0% - **Started:** 2026-10-01T06:48:01.132Z - **Finished:** 2026-10-01T06:50:06.697Z - **Download time:** 1544 ms - **Static scan time:** 4213 ms - **AI review time:** 119806 ms - **Total time:** 125565 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:** No confirmed attack was identified. Inspected runtime behavior supports Roblox integration, plugin setup, parser validation, licensing, and telemetry. - **Trigger:** Running the CLI starts the integration and plugin setup; npm installation has no lifecycle trigger. - **Impact:** The inspected behavior enables Roblox development and sends operational telemetry; no concrete malicious mutation or credential theft was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-01T06:50:06.697Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The runtime operates a local bridge, copies its bundled plugin, and verifies downloaded parser artifacts before use. - **Rationale:** Inspected execution, file writes, network clients, and parser loading are consistent with the Roblox integration. No concrete attack behavior or block-eligible installation chain was found. - **Files touched:** WeppyRobloxMCP.rbxm, device-id.json, telemetry-first-seen.json, license-state.json - **Network endpoints:** 127.0.0.1, https://apis.roblox.com, https://roblox-license-api.hope841026.workers.dev, https://www.google-analytics.com/mp/collect, https://weppy-operations-server.hope841026.workers.dev/public/mcp/device-observation/v1, https://api.ipify.org, https://github.com/hope1026/weppy-roblox-mcp/releases/download/luau-parser-v1.0.0/luau-parser.wasm ### Review decision - **Verdict:** Clean - **Confidence:** 87.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines only a start script, with no install lifecycle hooks or runtime self-dependency., The Roblox bridge defaults to 127.0.0.1, and plugin setup copies the bundled Roblox plugin., Downloaded Luau parser artifacts must match the embedded byte size and SHA-256 digest., Telemetry reports device and runtime metadata and can be disabled through ENABLE\_TELEMETRY., The Open Cloud client defaults to Roblox's API endpoint., The local Luau compiler is invoked for parsing with shell execution disabled. ## Affected versions and remediation This report applies to @weppy/roblox-mcp@2.14.0. - Review the evidence and your use of @weppy/roblox-mcp@2.14.0 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.
