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. This package contains broad but product-aligned MCP memory and local-session features. It has no npm install lifecycle hook, and its self-staging update path explicitly disables lifecycle scripts. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-06T04:29:26.446Z - **Finished:** 2026-09-06T04:30:52.838Z - **Download time:** 767 ms - **Static scan time:** 2386 ms - **AI review time:** 83238 ms - **Total time:** 86392 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 package's normal runtime features can contact its EchoMem service and, after explicit setup, configure its own integration hooks. - **Trigger:** Running the MCP bridge, or explicitly running its setup command with hook installation. - **Impact:** Normal product operations can access configured memory data and locally tracked sessions; no unconsented install-time action was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-06T04:30:52.838Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** MCP memory service, optional agent hooks, and managed runtime updates. - **Rationale:** This package contains broad but product-aligned MCP memory and local-session features. It has no npm install lifecycle hook, and its self-staging update path explicitly disables lifecycle scripts. - **Files touched:** .codex/hooks.json, .claude/settings.json, .echomem/mcp-runtime - **Network endpoints:** echo-mem-chrome.vercel.app ### Review decision - **Verdict:** Clean - **Confidence:** 84.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** The manifest exposes a CLI but no install lifecycle hook., The running bridge can stage a newer release of itself through npm after an update check., Explicit setup can add command hooks to Codex configuration., The source-session feature reads local Codex session metadata., The local HUD can serve tracked raw session files. - **Evidence against:** The self-install command uses npm's ignore-scripts option, so it does not trigger nested package lifecycle scripts., Hook installation is tied to setup options and names the installed hooks; it is not an npm install-time action., The HUD validates requested paths against its tracked-session list., No credential harvesting, secret exfiltration, opaque payload, or destructive behavior was found. ## Affected versions and remediation This report applies to @echomem/mcp@1.4.53. - Review the evidence and your use of @echomem/mcp@1.4.53 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.
