Running the CLI enables opt-out telemetry and selected init options generate project-local agent/MCP configuration. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Clean - **Confidence:** 91.0% - **Started:** 2026-08-19T04:44:02.865Z - **Finished:** 2026-08-19T04:44:57.202Z - **Download time:** 1539 ms - **Static scan time:** 5130 ms - **AI review time:** 47667 ms - **Total time:** 54337 ms ## Security analysis ### Published attack-surface review - **Summary:** No malicious install-time or stealth attack surface was confirmed. Running the CLI enables opt-out telemetry and selected init options generate project-local agent/MCP configuration. - **Trigger:** User runs the mastra CLI; agent files require selected init skills or --mcp. - **Impact:** Sends CLI telemetry to PostHog; selected initialization writes project configuration. - **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:** 2026-08-19T04:44:57.202Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** CLI telemetry plus explicit project scaffolding - **Rationale:** The scanner’s exfiltration and agent-control claims resolve to ordinary first-party CLI telemetry and explicitly selected scaffolding. No lifecycle hook, credential redirection, foreign-package overwrite, stealth persistence, or remote payload execution was found. - **Files touched:** ~/.mastra/analytics.json, AGENTS.md, CLAUDE.md, .cursor/mcp.json, .vscode/mcp.json - **Network endpoints:** https://us.posthog.com ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for:** CLI initializes PostHog telemetry to us.posthog.com when invoked., Explicit init options can write project MCP/agent guide files. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., MCP and AGENTS.md writes occur only in the init flow when skills or an MCP editor option is selected., Platform credentials are stored in ~/.mastra with restrictive directory/file modes for explicit login. ## Public findings ### 1.
