This report does not record a matching static-policy override reason. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed malicious attack surface was established. The observed network and code-execution behavior belongs to MCP tool operation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-09-15T21:44:50.203Z - **Finished:** 2026-09-15T21:46:17.491Z - **Download time:** 520 ms - **Static scan time:** 8573 ms - **AI review time:** 78194 ms - **Total time:** 87288 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 confirmed malicious attack surface was established. The observed network and code-execution behavior belongs to MCP tool operation. - **Trigger:** Starting the server or invoking an MCP tool. - **Impact:** Submitted code and configured API credentials may be processed by the declared Stainless service. - **Review source:** ai\_review - **Reviewed:** 2026-09-15T21:46:17.491Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Declared remote sandbox execution and documentation retrieval. - **Rationale:** The package has risky but product-aligned MCP code-execution features, with no install hook, persistence, harvesting, or covert execution found. Static hints of exfiltration match the declared remote sandbox flow rather than a confirmed malicious action. ### Review decision - **Verdict:** Clean - **Confidence:** 83.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Final policy explanation:** The AI recommended clean, but the final policy action is warn. This report does not record a matching static-policy override reason. - **Evidence for AI clean decision:** The default remote execute tool sends submitted code and a Plumery session value to a Stainless endpoint., The execute tool is enabled by default and selects remote execution unless local mode is requested., The local worker dynamically imports submitted TypeScript., Server startup fetches MCP instructions from Stainless and can attach a configured API key. - **Evidence against:** package.json has no preinstall, install, or postinstall hook., The package starts its server only when its bin entry is run directly., Network and code-execution behavior is confined to the declared MCP tools; no hidden persistence, filesystem harvesting, or destructive action was found. ## Affected versions and remediation This report applies to plumery-mcp@3.10.0. - Review the evidence and your use of plumery-mcp@3.10.0 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.
