Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The install lifecycle can modify existing AI-agent configurations without an explicit setup command. It registers the package and persistent command hooks that run during agent events. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-20T20:27:51.576Z - **Finished:** 2026-09-20T20:37:52.978Z - **Download time:** 1029 ms - **Static scan time:** 1449 ms - **AI review time:** 598924 ms - **Total time:** 601402 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:** The install lifecycle can modify existing AI-agent configurations without an explicit setup command. It registers the package and persistent command hooks that run during agent events. - **Trigger:** A global npm installation outside CI when a supported agent configuration directory exists. - **Impact:** Existing Claude Code, Devin CLI, Cursor, or Codex agent control surfaces can be altered and configured to execute package commands persistently. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-20T20:37:52.978Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall launches setup, which registers MCP configuration, installs lifecycle hooks, and installs a skill; hooks invoke remem-mcp commands during agent sessions. - **Attack narrative:** Installing the package globally can automatically invoke its setup flow. That flow modifies supported AI-agent configuration and hook surfaces, causing remem-mcp commands to run on future session and tool events. The global-install and existing-directory guards reduce scope but do not provide explicit consent for this lifecycle-driven control-surface mutation. - **Rationale:** This is an unconsented postinstall mutation of foreign AI-agent control surfaces with persistent command hooks. The qualifying guards do not remove the automatic lifecycle trigger. - **Files touched:** package.json, scripts/postinstall.js, dist/index.js ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The manifest runs a postinstall script automatically., On qualifying global installs, the postinstall script launches the package binary with the setup command., Setup automatically registers an MCP server, installs hooks, and installs a skill., The installed hook configuration executes remem-mcp commands at agent session start and tool-use events. - **Evidence against:** Automatic setup is limited to global installs outside CI and only when an agent configuration directory exists. ## Affected versions and remediation This report applies to remem-mcp@0.6.8. - Avoid installing remem-mcp@0.6.8. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
