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. Review flagged AI-agent configuration or capability changes. This remains warn-only unless evidence shows foreign-agent hijack through preinstall/install/postinstall, hidden persistence, exfiltration, remote code execution, or other concrete malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-09-03T18:55:05.711Z - **Finished:** 2026-09-03T18:56:18.255Z - **Download time:** 1029 ms - **Static scan time:** 7606 ms - **AI review time:** 63905 ms - **Total time:** 72544 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:** Installation fetches dependencies for the bundled MCP component. Starting the gateway modifies the user's Claude skill directory with package-provided skills. - **Trigger:** npm installation for the dependency setup; explicit gateway startup for skill synchronization. - **Impact:** A package-provided skill can affect later Claude sessions, and managed stale skill directories can be removed. - **Evidence paths:** package.json, dist/index.js, dist/skills/sync.js - **Review source:** ai\_review - **Reviewed:** 2026-09-03T18:56:18.255Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic MCP dependency installation and runtime synchronization of Claude skill files. - **Rationale:** The package has an automatic lifecycle dependency fetch and an explicit-runtime Claude skill mutation. These are risky extension behaviors but do not establish the policy threshold for malicious install-hook abuse. - **Files touched:** mcp/node\_modules, ~/.claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall runs Bun to install dependencies for the bundled MCP component., When the gateway is explicitly started, it copies bundled MCP skill files into the user's Claude skills directory., The skill synchronizer overwrites managed skill files and deletes stale marked skill directories. - **Evidence against:** The manifest has no runtime dependency on its own package name., The postinstall targets only the package's bundled MCP directory; no foreign AI-agent configuration write occurs at install time., The Claude skills mutation is reached during gateway startup, not package installation. ## Affected versions and remediation This report applies to @0xmaxma/claude-gateway@1.8.5. - Review the evidence and your use of @0xmaxma/claude-gateway@1.8.5 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.
