## Security analysis

### Published attack-surface review

- **Summary:** No confirmed malicious attack surface. The CLI performs project scaffolding, deployment, and optional MCP configuration only when its commands are invoked; global MCP configuration has an explicit confirmation.

- **Trigger:** User invokes mastra CLI commands, particularly init/create/deploy.

- **Impact:** May create or modify the selected project and, with explicit confirmation, selected editor MCP configuration; no install-time execution or covert exfiltration found.

- **Evidence paths:** package.json, dist/index.js, dist/create-CaJZFOGC.js, dist/analytics-Cz1-gjQi.js, dist/orgs-DoKnmO72.js

- **Review source:** ai\_review

- **Reviewed:** 2026-07-28T23:16:29.285Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** User-directed project setup, platform API access, optional telemetry, and optional MCP registration.

- **Rationale:** Direct inspection found a normal user-invoked CLI, no lifecycle hooks, and no concrete malicious chain. Scanner signals correspond to declared CLI functionality; MCP configuration mutation is explicit and globally scoped only after confirmation.

- **Files touched:** ~/.mastra/credentials.json, ~/.cursor/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.gemini/antigravity/mcp\_config.json, \<project\>/.cursor/mcp.json, \<project\>/.vscode/mcp.json

- **Network endpoints:** https://platform.mastra.ai, https://us.posthog.com, https://mastra.ai/api/templates.json

### Review decision

- **Verdict:** Clean

- **Confidence:** 96.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no preinstall/install/postinstall lifecycle hook., dist/index.js only runs CLI parsing after direct user invocation., dist/analytics-Cz1-gjQi.js gates MCP setup behind init --mcp or an interactive choice., Global MCP writes require an explicit confirmation naming the target config., dist/create-CaJZFOGC.js runs git/npx/package-manager commands only during create/init workflows., Telemetry is opt-out via MASTRA\_TELEMETRY\_DISABLED, with a documented PostHog host.
