Runtime forwards client LLM requests to configured providers. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Suspicious - **Confidence:** 92.0% - **Started:** 2026-08-11T04:05:27.712Z - **Finished:** 2026-08-11T04:06:41.837Z - **Download time:** 517 ms - **Static scan time:** 1116 ms - **AI review time:** 72489 ms - **Total time:** 74125 ms ## Security analysis ### Published attack-surface review - **Summary:** Installation starts a local detached proxy; global installation also registers it to start at login. Runtime forwards client LLM requests to configured providers. - **Trigger:** npm postinstall; then local proxy requests - **Impact:** Persistent local process and expected forwarding of prompts/API credentials to selected providers - **Evidence paths:** package.json, scripts/postinstall.js, scripts/preuninstall.js, dist/index.js, defaults/catalog.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-11T04:06:41.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time daemon and login persistence - **Rationale:** Source confirms install-time daemon startup and global login persistence, creating a real user-impacting risk. The observed network behavior is package-aligned proxy forwarding rather than a concrete malicious chain. - **Files touched:** scripts/postinstall.js, dist/index.js, defaults/catalog.json, service/llm-failover-proxy.mjs, daemon.json, daemon.log - **Network endpoints:** https://integrate.api.nvidia.com/v1, https://opencode.ai/zen/v1, https://openrouter.ai/api/v1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 92.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** scripts/postinstall.js auto-starts a detached daemon on install unless CI/npx/opt-out., Global install invokes enable, which writes a login-start entry., dist/index.js creates LaunchAgent/systemd/Startup persistence and copies its CLI into service/., The daemon forwards proxy requests and configured API keys to LLM providers. - **Evidence against:** README.md documents autostart, persistence, disable command, and LLM\_PROXY\_NO\_AUTOSTART., dist/index.js outbound fetches are to configured provider base URLs for the proxy's stated function., defaults/catalog.json contains only named LLM-provider endpoints; no unrelated collection endpoint found., No eval, remote code download, credential harvesting, or foreign AI-agent configuration writes found. ## Public findings ### 1.
