Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. This gateway installs its bundled MCP dependencies during npm installation and adds its packaged skills to the user's Claude skill directory when the gateway starts. No concrete malicious payload or package-controlled data receiver was confirmed. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-08-28T06:53:16.167Z - **Finished:** 2026-08-28T06:55:42.065Z - **Download time:** 756 ms - **Static scan time:** 7179 ms - **AI review time:** 137959 ms - **Total time:** 145898 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:** This gateway installs its bundled MCP dependencies during npm installation and adds its packaged skills to the user's Claude skill directory when the gateway starts. No concrete malicious payload or package-controlled data receiver was confirmed. - **Trigger:** Installing the package activates the Bun dependency install; running the gateway activates skill synchronization. - **Impact:** It can add or replace package-managed skills in the user's Claude environment, expanding the gateway's agent capabilities. - **Evidence paths:** package.json, dist/index.js, dist/skills/sync.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T06:55:42.065Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Bundled MCP setup and first-party Claude skill synchronization. - **Rationale:** The package is not proven malicious, but it performs an install-time dependency action and a runtime Claude skill setup action that merits a warning under the agent-extension lifecycle policy. The source ties those actions to the advertised gateway and MCP functionality rather than a concrete attack chain. - **Files touched:** package.json, mcp/, dist/index.js, dist/skills/sync.js, mcp/tools/ ### Review decision - **Verdict:** Suspicious - **Confidence:** 86.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook automatically runs Bun dependency installation for the bundled MCP component., Starting the gateway copies bundled skill files into the user's Claude skills directory., The skill synchronizer writes packaged skill content and later removes only entries marked as its own. - **Evidence against:** No package-controlled credential collection or exfiltration endpoint was found in the inspected source., The observed network calls target configured service APIs or package-update infrastructure., The Claude skill changes occur when the user starts the gateway, not during installation. ## Affected versions and remediation This report applies to @0xmaxma/claude-gateway@1.8.2. - Review the evidence and your use of @0xmaxma/claude-gateway@1.8.2 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
