Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Allowed — no malicious behavior detected** — No malicious behavior detected. 21 low-signal pattern(s) reviewed. - **Verdict:** Clean - **Product-default install policy:** Allow - **Firewall policy:** No policy match - **Public report status:** Published - **Threat category:** None published - **Selected version:** 0.10.129 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source inspection found an output-only postinstall hook and no confirmed attack behavior. The scanner’s credential and agent-configuration signals map to service-aligned search and explicit setup behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-09T17:50:26.987Z - **Finished:** 2026-10-09T17:51:33.867Z - **Download time:** 1269 ms - **Static scan time:** 2487 ms - **AI review time:** 63123 ms - **Total time:** 66880 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 attack surface was identified in the inspected source. The flagged credential and agent configuration behavior is consistent with the package’s Cachly service and explicit setup features. - **Trigger:** The package’s postinstall hook runs during installation; its runtime tools and setup commands require their respective invocation. - **Impact:** No confirmed credential exfiltration, unconsented agent control-surface mutation, or other attack was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-09T17:51:33.867Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall prints guidance only. Semantic search uses a Cachly token in its default service URL; the operator-configured vector URL replaces that URL, and the search request sends the query payload. - **Rationale:** Source inspection found an output-only postinstall hook and no confirmed attack behavior. The scanner’s credential and agent-configuration signals map to service-aligned search and explicit setup behavior. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The postinstall hook only prints setup guidance; it does not perform the advertised configuration changes., Credential persistence updates Cachly’s own MCP entry, while ambient hooks read the key from the environment or local credentials file., Semantic search uses the Cachly vector token in its default URL; a configured vector URL replaces that URL, and the request sends the search payload., The agent-related code inspected builds hooks and setup guidance; the inspected setup and git-hook paths are explicit CLI features., The benchmark, git hook, and author helper findings are scoped to benchmarking, post-commit setup, and reading Git configuration. ## Affected versions and remediation This report applies to @cachly-dev/mcp-server@0.10.129. - Review the evidence and your use of @cachly-dev/mcp-server@0.10.129 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.
