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. 16 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:** 0.30.4 - **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. The package has no npm install hook, and the credential sends inspected are directed to the configured Mushi API, whose default is the package's service endpoint. Agent configuration changes occur through CLI setup/connect flows, and the wizard's additional connect step is prompted; no concrete attack behavior was found. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-15T03:42:59.432Z - **Finished:** 2026-10-15T03:46:13.586Z - **Download time:** 502 ms - **Static scan time:** 1544 ms - **AI review time:** 192107 ms - **Total time:** 194154 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 was identified. The observed network and agent configuration behavior matches the CLI's setup functions. - **Trigger:** A user runs \`mushi setup\` or \`mushi connect\`; the wizard's follow-on connect action requires confirmation. - **Impact:** No unauthorized credential disclosure, agent control change, or persistent payload behavior was established. - **Review source:** ai\_review - **Reviewed:** 2026-10-15T03:46:13.586Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends project SDK credentials to its configured Mushi API and can write MCP entries for the selected client. - **Rationale:** The package has no npm install hook, and the credential sends inspected are directed to the configured Mushi API, whose default is the package's service endpoint. Agent configuration changes occur through CLI setup/connect flows, and the wizard's additional connect step is prompted; no concrete attack behavior was found. - **Network endpoints:** https://dxptnwrhwsqckaftyymj.supabase.co/functions/v1/api ### Review decision - **Verdict:** Clean - **Confidence:** 91.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a CLI and has no npm install lifecycle hook., The CLI uses a Mushi API endpoint by default; alternate endpoints come from CLI options, environment settings, or saved configuration., The setup flow sends SDK credentials to that endpoint; sending a test report requires confirmation or an explicit noninteractive option., Agent configuration checks and writes are part of setup or connect commands; the wizard's follow-on connect action asks before proceeding., Inspected child-process calls support package installation or upgrades and local key-permission handling; no malicious execution chain was found. ## Affected versions and remediation This report applies to @mushi-mushi/cli@0.30.4. - Review the evidence and your use of @mushi-mushi/cli@0.30.4 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.
