The CLI prompts the user for an Anthropic API key (sk-ant-...) and writes it, together with a hardcoded gateway base URL https://api-anthropic.help, into Claude Desktop's configuration in every location it can reach: Windows registry policies at HKCU\\SOFTWARE\\Policies\\Claude via reg.exe, macOS managed preferences for com.anthropic.claudefordesktop via \`defaults write\`, claude\_desktop\_config.json, and all profile... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-10-20T18:49:28.712Z - **Finished:** 2026-10-20T18:50:08.132Z - **Download time:** 520 ms - **Static scan time:** 72 ms - **AI review time:** 38828 ms - **Total time:** 39420 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 user-run CLI configures Claude Desktop to use a third-party inference gateway. - **Trigger:** The user invokes the CLI and provides or enters a gateway API key. - **Impact:** Claude Desktop requests are configured to use that gateway; the source presents this as the package's setup purpose. - **Review source:** ai\_review - **Reviewed:** 2026-10-20T18:50:08.132Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI displays the gateway URL and writes the selected URL and supplied key into Claude configuration. - **Rationale:** The source shows an explicit, user-invoked gateway setup flow, with the endpoint displayed and the gateway key supplied by the user. The manifest has no install lifecycle hook, and the configuration writes match the stated package purpose. - **Network endpoints:** https://api-anthropic.help ### 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 bin/cli.js as the CLI entry point and lists only a start script; it has no install lifecycle hook., The CLI identifies its purpose as configuring Claude Desktop for a third-party inference gateway and displays the gateway URL before applying configuration., The CLI prompts for a gateway API key when none is supplied and aborts if it is empty., The supplied URL and gateway key are written to Claude configuration as gateway settings; this is consistent with the stated setup function. - **Evidence against:** The default gateway is https://api-anthropic.help, a package-selected endpoint, though the CLI displays it and accepts a replacement URL. ## Affected versions and remediation This report applies to @decoopus/claude-setup@1.0.2. - Avoid installing @decoopus/claude-setup@1.0.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
