Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The active MCP server performs default telemetry collection. It fetches the user's public IP, combines it with a persistent device-derived identifier and usage events, and transmits the result externally. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-27T23:47:54.827Z - **Finished:** 2026-09-27T23:49:04.823Z - **Download time:** 1019 ms - **Static scan time:** 4584 ms - **AI review time:** 64391 ms - **Total time:** 69996 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 active MCP server performs default telemetry collection. It fetches the user's public IP, combines it with a persistent device-derived identifier and usage events, and transmits the result externally. - **Trigger:** Starting the dist/index.js MCP server. - **Impact:** User and device activity can be tracked externally without an affirmative runtime opt-in. - **Evidence paths:** dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-27T23:49:04.823Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Startup initializes telemetry; telemetry fetches the public IP and posts queued event payloads containing identifiers and the IP to external analytics infrastructure. - **Attack narrative:** When the MCP server starts, its bundled analytics manager is initialized with telemetry enabled by default. It generates or reuses a persistent device identifier, obtains the public IP address from an external service, and attaches the IP and device-derived identifier to telemetry payloads sent to Google Analytics. The bundle also contains a package-operated device-observation endpoint. This collection is unrelated to the manifest's stated Roblox Studio integration purpose and runs automatically during ordinary server use. - **Rationale:** The active entrypoint automatically collects and exports a persistent identifier, public IP address, and usage telemetry to third parties. This is a concrete data-exfiltration surface rather than an inert capability. - **Network endpoints:** https://api.ipify.org, https://www.google-analytics.com/mp/collect, https://weppy-operations-server.hope841026.workers.dev/public/mcp/device-observation/v1 ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest starts dist/index.js as the package entrypoint., The entrypoint enables telemetry by default for released versions and starts it during server startup., Telemetry retrieves the public IP address and persists a device identifier., Queued telemetry adds the public IP and device-derived identifier before posting to Google Analytics., The bundle defines a separate package-operated device-observation endpoint. - **Evidence against:** No npm preinstall, install, or postinstall hook is declared in the manifest. ## Affected versions and remediation This report applies to @weppy/roblox-mcp@2.14.4. - Avoid installing @weppy/roblox-mcp@2.14.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
