This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 84.0% - **Started:** 2026-08-12T05:00:35.608Z - **Finished:** 2026-08-12T05:02:07.130Z - **Download time:** 765 ms - **Static scan time:** 5218 ms - **AI review time:** 85537 ms - **Total time:** 91522 ms ## Security analysis ### Published attack-surface review - **Summary:** No install-time attack surface was found. Explicit \`mastra init --mcp\` may configure Mastra's docs MCP server in a user-selected editor, and CLI use emits telemetry unless disabled. - **Trigger:** User runs the CLI, or explicitly runs \`mastra init --mcp \\`. - **Impact:** Machine metadata is sent to PostHog; selected editor config can gain a Mastra docs MCP entry. - **Evidence paths:** package.json, dist/index.js, dist/analytics-BYD-0skL.js, dist/client-x6vJatG\_.js, dist/credentials-CE1thn6C.js - **Review source:** ai\_review - **Reviewed:** 2026-08-12T05:02:07.130Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Opt-out telemetry and explicit editor MCP configuration. - **Rationale:** Source inspection found a normal CLI with no lifecycle scripts, but its explicit agent-editor configuration and default telemetry are security-relevant. The MCP write is user-command/option gated rather than unconsented installation-time control-surface mutation. - **Files touched:** ~/.mastra/analytics.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.gemini/antigravity/mcp\_config.json, \/.cursor/mcp.json, \/.vscode/mcp.json, \/AGENTS.md, \/CLAUDE.md - **Network endpoints:** https://us.posthog.com, https://platform.mastra.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** Default CLI telemetry captures hostname and system metadata to PostHog., \`mastra init --mcp\` can modify selected editor MCP configuration, including global Cursor/Windsurf/Antigravity paths. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., MCP and project guide writes occur only in the explicit init flow after the selected \`--mcp\` option., Authentication requests target the configured Mastra platform endpoint; credentials are stored locally with restrictive permissions. ## Public findings ### 1.
