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. 15 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:** 0.31.0 - **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: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. Source review did not confirm malicious behavior: credential sends use the configured Mushi API endpoint, and agent configuration changes occur through setup flows. Scanner hints about credential redirection and exfiltration were not supported by the inspected source. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-20T16:34:01.188Z - **Finished:** 2026-10-20T16:34:57.955Z - **Download time:** 2333 ms - **Static scan time:** 1585 ms - **AI review time:** 52848 ms - **Total time:** 56767 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 reviewed credential requests target the configured Mushi API endpoint, and agent configuration writes occur in setup flows. - **Trigger:** Running the CLI’s setup or connect commands. - **Impact:** No confirmed attack surface was established from the inspected source. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T16:34:57.955Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI sends Mushi SDK credentials to the configured API and can write project-level MCP configuration during setup. - **Rationale:** Source review did not confirm malicious behavior: credential sends use the configured Mushi API endpoint, and agent configuration changes occur through setup flows. Scanner hints about credential redirection and exfiltration were not supported by the inspected source. ### Review decision - **Verdict:** Clean - **Confidence:** 90.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest defines a CLI entrypoint and no install lifecycle hook; its scripts are build, lint, test, and typecheck., The CLI’s default API endpoint is Mushi’s configured service, and endpoint selection accepts an explicit value or MUSHI\_API\_ENDPOINT., Wizard requests send the SDK key to that endpoint; the wizard telemetry call is skipped when MUSHI\_NO\_TELEMETRY is set., MCP configuration writes occur during explicit setup flows and use project-level Cursor configuration; the inspected agent integration locations do not establish unconsented lifecycle mutation., The inspected runtime dependencies expose prompt, command-line, and keyring functionality, and their manifests declare no install scripts. ## Affected versions and remediation This report applies to @mushi-mushi/cli@0.31.0. - Review the evidence and your use of @mushi-mushi/cli@0.31.0 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.
