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:** 2026-10-22T07:04:23.437Z - **Finished:** 2026-10-22T07:05:07.837Z - **Download time:** 520 ms - **Static scan time:** 72 ms - **AI review time:** 43807 ms - **Total time:** 44400 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 confirmed attack surface was identified. The CLI configures Claude Desktop for a third-party inference gateway as its stated purpose. - **Trigger:** A user runs the setup CLI and supplies or enters a gateway API key. - **Impact:** Claude Desktop requests use the configured gateway; the inspected code does not secretly send the entered key elsewhere. - **Review source:** ai\_review - **Reviewed:** 2026-10-22T07:05:07.837Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The CLI displays the gateway URL and saves that URL and the supplied key in Claude Desktop settings. - **Rationale:** The reviewed source implements an explicitly invoked gateway setup tool, with the destination shown to the user and configurable. Its publisher-selected default endpoint merits attention, but the source supports the stated third-party gateway purpose and shows no concealed credential transfer or automatic install-time action. - **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:** The manifest provides a CLI entrypoint and only a start script; it declares no install lifecycle hook., The CLI prompts for an API key, displays the gateway URL, and stores the supplied key and URL in Claude Desktop settings as part of its setup function. - **Evidence against:** The CLI selects https://api-anthropic.help as its default gateway, though it displays the destination and accepts a URL override. ## Affected versions and remediation This report applies to @decoopus/claude-setup@1.0.0. - Avoid installing @decoopus/claude-setup@1.0.0. 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.
