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:** 90.0% - **Started:** 2026-08-14T00:35:21.339Z - **Finished:** 2026-08-14T00:36:05.190Z - **Download time:** 520 ms - **Static scan time:** 5152 ms - **AI review time:** 38178 ms - **Total time:** 43851 ms ## Security analysis ### Published attack-surface review - **Summary:** No install-time attack surface was found. Explicit \`mastra init --mcp\` can alter selected project or global editor MCP configuration, and CLI execution emits opt-out telemetry containing host/system metadata. - **Trigger:** User runs the CLI, particularly \`mastra init --mcp \\`. - **Impact:** A selected editor may later run Mastra's docs MCP package; telemetry reveals machine and command metadata to PostHog. - **Evidence paths:** package.json, dist/index.js, dist/analytics-BYD-0skL.js, dist/client-x6vJatG\_.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T00:36:05.190Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** User-selected MCP configuration plus default CLI telemetry. - **Rationale:** Source inspection contradicts the scanner's claimed credential redirect and foreign-package overwrite chain. The remaining concern is explicit global/editor MCP configuration and default telemetry, so it warrants a warning rather than a malicious block. - **Files touched:** .cursor/mcp.json, .vscode/mcp.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.gemini/antigravity/mcp\_config.json, ~/.mastra/analytics.json - **Network endpoints:** https://us.posthog.com, https://platform.mastra.ai ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Benign - **False-positive risk:** High - **Evidence for:** CLI initializes default-enabled PostHog telemetry and sends a persistent machine-derived identifier., \`mastra init --mcp\` can merge a Mastra MCP entry into global Cursor, Windsurf, or Antigravity configuration., The MCP entry executes \`npx -y @mastra/mcp-docs-server\` when the selected editor loads it. - **Evidence against:** package.json has no preinstall, install, postinstall, or prepare lifecycle hook., MCP configuration occurs only after the explicit \`init\` flow supplies \`mcpServer\`; the CLI exposes it as \`--mcp \\`., Platform network clients use configurable Mastra endpoints and authenticated user tokens for declared CLI operations. ## Public findings ### 1.
