Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No confirmed attack surface was identified. Inspected execution and credential handling support the MCP server's API tools; no hidden external receiver was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-06T10:51:15.307Z - **Finished:** 2026-10-06T10:52:26.980Z - **Download time:** 520 ms - **Static scan time:** 5900 ms - **AI review time:** 65252 ms - **Total time:** 71673 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 attack surface was identified. Inspected execution and credential handling support the MCP server's API tools; no hidden external receiver was found. - **Trigger:** The user launches the MCP server and invokes its execute tool. - **Impact:** The tool can perform authenticated API operations requested by its caller; inspected source does not establish covert exfiltration or malicious installation behavior. - **Review source:** ai\_review - **Reviewed:** 2026-10-06T10:52:26.980Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Caller-supplied code runs through a local Deno worker using the authenticated SDK, with network access limited to the SDK endpoint hostname. - **Rationale:** Inspected source shows user-invoked API execution and ordinary SDK authentication, without concrete malicious behavior. The scanner's exfiltration and similarity labels are unsupported by the inspected execution path. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Final policy explanation:** The AI recommended clean. Static policy retained a warning. The static scanner classified the package as malicious with confidence of at least 85%. A critical static finding has confidence of at least 90%. These conditions do not mean that the AI confirmed malicious behavior. - **Evidence for AI clean decision:** package.json has no install lifecycle hooks or runtime self-dependency., code-tool.js executes tool requests in a Deno worker with network access restricted to the SDK endpoint hostname., code-tool-worker.js evaluates caller-supplied code against the SDK and returns results to the requester., server.js supplies PLUMERY\_SESSION to the Plumery SDK for ordinary service authentication., index.js starts the server only when invoked as the main program. ## Affected versions and remediation This report applies to plumery-mcp@3.13.0. - Review the evidence and your use of plumery-mcp@3.13.0 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.
