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. Installation automatically invokes Bun to install the bundled MCP project's dependencies. On explicit gateway startup, bundled skills are copied into the user's Claude skills directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-11T10:00:00.477Z - **Finished:** 2026-09-11T10:01:04.549Z - **Download time:** 761 ms - **Static scan time:** 8837 ms - **AI review time:** 54470 ms - **Total time:** 64072 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 automatically invokes Bun to install the bundled MCP project's dependencies. On explicit gateway startup, bundled skills are copied into the user's Claude skills directory. - **Trigger:** npm installation for the nested dependency installation; explicit gateway startup for skill synchronization. - **Impact:** Nested dependency lifecycle code may run at install time, and runtime skill files can affect Claude's available tool instructions. - **Evidence paths:** package.json, dist/index.js, dist/packages/registry.js - **Review source:** ai\_review - **Reviewed:** 2026-09-11T10:01:04.549Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic nested dependency installation and runtime Claude skill synchronization. - **Rationale:** This has a real but bounded install-hook and agent-extension risk: an automatic nested installer and runtime synchronization into Claude's skills directory. The evidence does not meet the policy threshold for malicious behavior because no self-dependency, obfuscation, exfiltration, or unconsented install-time broad control-surface mutation was found. - **Files touched:** mcp/node\_modules, ~/.claude/skills ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Its automatic postinstall runs Bun to install a nested MCP dependency tree., When the gateway is started, it copies bundled skill files into the user's Claude skills directory and watches them for later updates., Its runtime updater can execute global npm installation commands. - **Evidence against:** The nested MCP manifest has ordinary declared dependencies and no lifecycle hook., The package does not runtime-depend on another release of itself., The Claude-directory writes occur during explicit gateway startup, not during npm installation., No credential exfiltration, obfuscated payload, or unconsented broad agent-control mutation was confirmed. ## Affected versions and remediation This report applies to @0xmaxma/claude-gateway@1.8.13. - Review the evidence and your use of @0xmaxma/claude-gateway@1.8.13 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.
