Network telemetry and editor configuration occur only during CLI use; editor setup is explicitly selected. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 94.0% - **Started:** 2026-08-21T01:27:07.865Z - **Finished:** 2026-08-21T01:28:12.454Z - **Download time:** 504 ms - **Static scan time:** 5886 ms - **AI review time:** 58198 ms - **Total time:** 64589 ms ## Security analysis ### Published attack-surface review - **Summary:** No confirmed malicious attack surface. Network telemetry and editor configuration occur only during CLI use; editor setup is explicitly selected. - **Trigger:** User runs the mastra CLI, especially init and selected platform/auth commands. - **Impact:** No install-time execution, unconsented broad control-surface mutation, or credential exfiltration chain was confirmed. - **Evidence paths:** package.json, dist/index.js, dist/analytics-BYD-0skL.js, dist/credentials-CE1thn6C.js, dist/client-x6vJatG\_.js - **Review source:** ai\_review - **Reviewed:** 2026-08-21T01:28:12.454Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-invoked CLI telemetry, platform API access, and optional project/editor setup. - **Rationale:** The scanner's alleged credential redirect and foreign-package overwrite are not supported by inspected source. The package is a user-invoked CLI with package-aligned platform/auth traffic, opt-out telemetry, and explicitly selected setup actions. - **Files touched:** .mastra/analytics.json, .cursor/mcp.json, .vscode/mcp.json - **Network endpoints:** https://us.posthog.com, https://platform.mastra.ai ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** CLI execution initializes opt-out PostHog telemetry with system metadata., The interactive init flow can add a Mastra MCP server to selected editor configuration. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., MCP configuration is gated by explicit interactive selection; global editor choices require confirmation., The entrypoint registers user-invoked CLI commands and parses argv., Authentication requests target configured Mastra platform endpoints; no unrelated credential receiver was found. ## Public findings ### 1.
