At next login it runs \`kcgrouter --daemon\` in the background. - **Trigger:** npm postinstall, followed by user login - **Impact:** A local AI gateway daemon is started without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.mjs, src/cli/daemon.ts, src/server/routes/cli-tools.routes.ts - **Review source:** ai\_review - **Reviewed:** 2026-08-17T00:05:36.488Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** cross-platform user-login persistence - **Rationale:** The package has confirmed unconsented install-time persistence but no confirmed malicious payload, credential exfiltration, or foreign AI-agent control-surface mutation. Warn rather than block under the stated decision boundary. - **Files touched:** scripts/postinstall.mjs, ~/Library/LaunchAgents/com.kcgrouter.plist, ~/.config/autostart/kcgrouter.desktop, %APPDATA%/Microsoft/Windows/Start Menu/Programs/Startup/kcgrouter-startup.vbs ### Review decision - **Verdict:** Suspicious - **Confidence:** 95.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for:** package.json runs a postinstall lifecycle script., The postinstall script automatically registers a user-login startup task unless an opt-out environment variable is set., The startup entries launch kcgrouter as a background daemon; this is unconsented install-time persistence. - **Evidence against:** No credential harvesting, remote payload loading, or exfiltration was found in inspected lifecycle and startup code., Observed network use is package-aligned AI-provider routing and an npm version check., AI-client configuration writes are authenticated dashboard actions, not install-time mutations. ## Public findings ### 1.
