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 flagged process execution and dynamic code support the package’s stated browser automation purpose and are exposed through user-invoked tools. The manifest has no install hooks, and the observed external host serves Chrome for Testing metadata for the browser download feature. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 93.0% - **Started:** 2026-10-29T03:20:59.918Z - **Finished:** 2026-10-29T03:21:54.072Z - **Download time:** 514 ms - **Static scan time:** 1741 ms - **AI review time:** 51897 ms - **Total time:** 54154 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 flagged execution and network behavior serves browser automation and related tooling. - **Trigger:** Browser operations run when a user invokes MCP tools; browser code runs when the user calls \`browser\_run\_code\`. - **Impact:** These capabilities can access pages and run code in the browser context, as expected for this package; no automatic malicious data collection or unrelated execution was identified. - **Review source:** ai\_review - **Reviewed:** 2026-10-29T03:21:54.072Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The package launches browser or server processes and can execute user-supplied Playwright snippets. It may fetch Chrome for Testing metadata to download the browser. - **Rationale:** The flagged process execution and dynamic code support the package’s stated browser automation purpose and are exposed through user-invoked tools. The manifest has no install hooks, and the observed external host serves Chrome for Testing metadata for the browser download feature. - **Files touched:** ~/.cache/chrome-for-testing - **Network endpoints:** googlechromelabs.github.io ### Review decision - **Verdict:** Clean - **Confidence:** 93.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The package provides a Playwright browser automation MCP server, matching its stated purpose., The manifest has no install, preinstall, or postinstall hook., The \`browser\_run\_code\` capability is exposed as a named tool and runs code supplied to that tool., Chrome for Testing metadata is fetched from \`googlechromelabs.github.io\` as part of the browser download feature. - **Evidence against:** The package includes shell process execution for starting a requested browser server., The browser code tool evaluates JavaScript and can run saved snippets., The package supports network telemetry and browser communication. ## Affected versions and remediation This report applies to @agimon-ai/po-browse-tool@0.0.0-alpha.66. - Review the evidence and your use of @agimon-ai/po-browse-tool@0.0.0-alpha.66 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.
