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 is not clearly malicious: its network behavior serves the stated memory feature and connection requires browser approval. However, the automatically installed session-end hook sends the full transcript to the service while relying on a server-side opt-in check, and the package does not establish that transcripts are withheld when learning is disabled; warn about this collection ambiguity. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-11-02T19:40:46.197Z - **Finished:** 2026-11-02T19:41:15.556Z - **Download time:** 1018 ms - **Static scan time:** 846 ms - **AI review time:** 27495 ms - **Total time:** 29359 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:** A connected installation adds Claude Code hooks that retrieve saved patterns at session start and submit the session transcript at session end. - **Trigger:** The user runs \`memnar connect\`, approves the browser pairing, and later ends a Claude Code session. - **Impact:** The service receives the full session transcript. The package does not show that transcript upload is skipped when automatic learning is disabled, leaving uncertainty about collection scope and consent. - **Evidence paths:** index.js, hooks/mindfile-session-end.sh, hooks/mindfile-session-start.sh - **Review source:** ai\_review - **Reviewed:** 2026-11-02T19:41:15.556Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SessionEnd hook reads the transcript path from hook input and POSTs the transcript with the saved Memnar token to the capture endpoint; the source says opt-in is checked server-side. - **Rationale:** The package is not clearly malicious: its network behavior serves the stated memory feature and connection requires browser approval. However, the automatically installed session-end hook sends the full transcript to the service while relying on a server-side opt-in check, and the package does not establish that transcripts are withheld when learning is disabled; warn about this collection ambiguity. - **Files touched:** ~/.claude/settings.json, ~/.mindfile/token - **Network endpoints:** https://app.memnar.ai, https://kvrwtxjayijgkamfnavy.supabase.co ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The manifest describes Memnar as a Claude Code memory tool and defines no install lifecycle hook., The CLI starts its connection flow only when the user runs \`connect\`; that flow opens a browser for approval., The installed SessionEnd hook reads Claude Code’s transcript and POSTs it to the hosted capture endpoint, even though the script says the server checks whether learning is enabled., The CLI says to turn on automatic learning in Settings, but the package does not establish whether the full transcript is withheld from the service when learning is off. - **Evidence against:** The connection flow requires browser approval before saving a token and installing hooks., The hook describes its purpose as extracting candidate patterns, scrubbing secrets, and checking opt-in server-side., The SessionStart hook only retrieves patterns from the configured Memnar service when a token exists. ## Affected versions and remediation This report applies to memnar@0.3.1. - Review the evidence and your use of memnar@0.3.1 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.
