## Verdict summary
**Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected.

- **Verdict:** Suspicious
- **Product-default install policy:** Warn
- **Firewall policy:** Warn-only agent extension risk
- **Public report status:** Published
- **Threat category:** Agent extension lifecycle risk
- **Selected version:** 1.4.0
- **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.

The package has no npm install lifecycle hook, and its configuration changes require an explicit CLI command. Its automatic hooks, remote content transfer, and server-instructed detached Codex execution warrant a warning rather than a block.

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:** An explicit setup command modifies Codex configuration and installs hooks. Those hooks can send conversation content to the package service and start a detached Codex process based on a server response.

- **Trigger:** The user runs \`memoryrouter-codex init\` with hooks enabled, then uses Codex.

- **Impact:** A trusted service response can influence an unattended local agent run and receives captured conversation content.

- **Evidence paths:** lib/installer.cjs, lib/hooks.cjs, runtime/hook.cjs, runtime/auto.cjs, runtime/reflect.cjs, runtime/api.cjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-28T18:22:16.858Z

### AI review details

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

- **Mechanism:** Installed Codex hooks invoke remote memory APIs and launch server-instructed consolidation.

- **Rationale:** The package has no npm install lifecycle hook, and its configuration changes require an explicit CLI command. Its automatic hooks, remote content transfer, and server-instructed detached Codex execution warrant a warning rather than a block.

- **Files touched:** ~/.codex/config.toml, ~/.codex/hooks.json, ~/.codex/AGENTS.md, ~/.codex/memoryrouter/runtime, \<project\>/.codex/config.toml, \<project\>/.codex/hooks.json, \<project\>/AGENTS.md, \<project\>/.codex/memoryrouter/runtime, ~/.memoryrouter/codex

- **Network endpoints:** https://api.memoryrouter.ai, https://mcp.memoryrouter.ai/mcp

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 91.0%

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

- **Intent class:** Dangerous Capability

- **False-positive risk:** Low

- **Evidence for warning:** The explicit init command writes Codex MCP, hook, and AGENTS configuration., Installed hooks automatically start a detached background consolidation process when the API reports a suggestion., The background flow passes server-provided reflection instructions to \`codex exec\`., The runtime sends prompts and completed assistant messages to the MemoryRouter API when hooks are enabled.

- **Evidence against:** package.json contains no preinstall, install, or postinstall lifecycle hook., Control-surface changes require the user to run \`memoryrouter-codex init\`; hooks and AGENTS changes can be disabled., The project MCP command pins the same package version rather than selecting an older release., No credential harvesting, obfuscated payload, or unrelated network endpoint was found.

## Affected versions and remediation
