The proxy forwards client requests and configured provider API keys to configured upstream LLM endpoints. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 95.0% - **Started:** 2026-08-11T04:05:27.768Z - **Finished:** 2026-08-11T04:06:41.733Z - **Download time:** 506 ms - **Static scan time:** 1075 ms - **AI review time:** 72382 ms - **Total time:** 73965 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically starts a persistent local LLM proxy. The proxy forwards client requests and configured provider API keys to configured upstream LLM endpoints. - **Trigger:** npm postinstall for non-npx, non-CI installs; explicit enable adds login persistence. - **Impact:** Unexpected background process and outbound LLM request forwarding; no concrete malicious chain confirmed. - **Evidence paths:** package.json, scripts/postinstall.js, scripts/preuninstall.js, dist/index.js, defaults/catalog.json - **Review source:** ai\_review - **Reviewed:** 2026-08-11T04:06:41.733Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** detached local proxy daemon with optional user-login service registration - **Rationale:** Source confirms an install-time background service and optional login persistence, warranting a warning. Its network and secret handling are aligned with the documented LLM proxy function, with no concrete malicious behavior found. - **Files touched:** scripts/postinstall.js, dist/index.js, defaults/catalog.json - **Network endpoints:** https://integrate.api.nvidia.com/v1, https://opencode.ai/zen/v1, https://openrouter.ai/api/v1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., scripts/postinstall.js starts dist/index.js daemon on install unless opted out/CI/npx., dist/index.js detaches a background proxy and copies its CLI into a service directory., dist/index.js enable writes user login persistence entries. - **Evidence against:** The automatic login entry is only created by explicit enable, not local postinstall., Default server binds to 127.0.0.1., Network requests forward user proxy requests only to configured LLM providers., No credential harvesting, unrelated exfiltration, eval, or remote payload loading found. ## Public findings ### 1.
