Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The manifest has no install lifecycle hook, and the runtime’s environment-key use is part of caller-invoked Cursor SDK setup. The inspected source shows no concrete attack behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 97.0% - **Started:** 2026-10-21T12:10:13.735Z - **Finished:** 2026-10-21T12:10:45.293Z - **Download time:** 255 ms - **Static scan time:** 109 ms - **AI review time:** 31194 ms - **Total time:** 31558 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. The package wraps the Cursor SDK for caller-invoked agent runs. - **Trigger:** A caller invokes the exported agent’s runtime methods. - **Impact:** No unauthorized credential transfer, install-time action, or other concrete attack was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-21T12:10:45.293Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The wrapper resolves an SDK agent using caller options and, when needed, the Cursor API key from the environment, then sends the supplied prompt through the SDK. - **Rationale:** The manifest has no install lifecycle hook, and the runtime’s environment-key use is part of caller-invoked Cursor SDK setup. The inspected source shows no concrete attack behavior. - **Files touched:** package.json, dist/index.js ### Review decision - **Verdict:** Clean - **Confidence:** 97.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest points to the \`dist\` runtime and lists build, test, and lint scripts without install lifecycle hooks., Runtime agent creation occurs when \`generate\` is called, and the wrapper sends the supplied prompt through the Cursor SDK., The API key comes from caller options or \`CURSOR\_API\_KEY\` and is passed into Cursor SDK creation options. ## Affected versions and remediation This report applies to @mastra/cursor@0.3.3. - Review the evidence and your use of @mastra/cursor@0.3.3 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
