## Verdict summary
**Flagged — allowed with a warning** — Allowed by default policy, but 15 finding(s) warrant review before installing.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Matched warn-list
- **Public report status:** Published
- **Threat category:** Remote Code Execution
- **Selected version:** 1.4.37
- **Selected version is latest:** No
- **Analysis source:** AI Security Review (lpm-firewall-ai)

This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions.

AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy.

No concrete malicious chain or npm lifecycle abuse was found. Automatic remote runtime replacement and optional agent-hook installation remain material dangerous capabilities requiring a warning.

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:** On MCP-server startup, a registry-reported update is automatically staged with npm and selected for a future MCP session. The package also offers explicit commands that modify Codex/Claude hooks and a macOS LaunchAgent.

- **Trigger:** Run the MCP server; an available registry update triggers the background installer.

- **Impact:** A newer registry package can become executable in a later MCP session without a separate update command.

- **Evidence paths:** package.json, dist/index.js, dist/headless-runtime.js, dist/update-check.js, dist/hud/hooks.js, dist/hud/autostart.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-09T04:21:29.099Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** automatic remote package staging and dynamic entry import

- **Rationale:** No concrete malicious chain or npm lifecycle abuse was found. Automatic remote runtime replacement and optional agent-hook installation remain material dangerous capabilities requiring a warning.

- **Files touched:** $ECHO\_CONFIG\_DIR/mcp-runtime/active.json, $ECHO\_CONFIG\_DIR/mcp-runtime/launcher.mjs, ~/.codex/hooks.json, ~/.claude/settings.json, ~/Library/LaunchAgents/com.echomem.hud.plist

- **Network endpoints:** https://registry.npmjs.org/%40echomem%2Fmcp/latest, https://echo-mem-chrome.vercel.app

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 88.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Low

- **Evidence for warning:** dist/index.js auto-installs a newer package after its background update check., dist/headless-runtime.js runs npm install and creates a launcher that dynamically imports the installed entry., dist/hud/hooks.js can add executable hooks to ~/.codex and ~/.claude.

- **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., Hook and autostart writes are reached only through named HUD CLI/UI actions., Network API calls target the declared EchoMem service and use the stored bearer token.

## Affected versions and remediation
