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. Static source inspection found no malicious behavior: the reported credential flow is Google IAP authentication scoped to the configured admin, while file export is an explicit user-invoked feature. The manifest has no install lifecycle hook, and the inspected export target does not show hidden agent configuration mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-12T09:38:29.413Z - **Finished:** 2026-10-12T09:39:16.751Z - **Download time:** 766 ms - **Static scan time:** 65 ms - **AI review time:** 46507 ms - **Total time:** 47338 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 surface was identified in the inspected credential and export flows. The package uses Google credentials for configured IAP authentication and offers an explicit command to write fetched Caelo context to files. - **Trigger:** The export flow runs when the user invokes the export command; IAP signing runs when requests need authorization and the service-account setting is present. - **Impact:** No unrelated credential disclosure, hidden agent configuration change, or unconsented install-time action was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-12T09:39:16.751Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The code signs a JWT for the configured Caelo admin origin using Google's IAM Credentials API, and sends the Caelo token and IAP authorization to that admin URL. Export writes context returned by that admin into the selected output directory. - **Rationale:** Static source inspection found no malicious behavior: the reported credential flow is Google IAP authentication scoped to the configured admin, while file export is an explicit user-invoked feature. The manifest has no install lifecycle hook, and the inspected export target does not show hidden agent configuration mutation. - **Files touched:** dist/export.js - **Network endpoints:** https://iamcredentials.googleapis.com ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json has no install lifecycle hook; its only publish hook runs the TypeScript build., The export feature fetches live context and writes generated agent files only when the user invokes the export command., The IAP helper uses a configured service account and the Caelo admin URL as the JWT audience., The Google access token is sent to Google's IAM Credentials API to sign that JWT., The shared HTTP client sends the Caelo token and IAP authorization to the configured admin URL. - **Evidence against:** The flagged credential flow is for Google IAP authentication to the configured Caelo admin, not a transfer to an unrelated recipient., The export target describes explicitly generated files from the authenticated admin's live context; it does not establish hidden agent configuration mutation. ## Affected versions and remediation This report applies to @caelo-cms/mcp-server@0.10.38. - Review the evidence and your use of @caelo-cms/mcp-server@0.10.38 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.
