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 installs dependencies for a bundled MCP component. At runtime, the gateway can launch Claude with permissions disabled and write auto-generated agent skills. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-07T15:25:14.886Z - **Finished:** 2026-09-07T15:26:35.223Z - **Download time:** 256 ms - **Static scan time:** 8190 ms - **AI review time:** 71888 ms - **Total time:** 80337 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 installs dependencies for a bundled MCP component. At runtime, the gateway can launch Claude with permissions disabled and write auto-generated agent skills. - **Trigger:** Installing the package when Bun is available; later running the gateway and using its agent features. - **Impact:** The package creates a high-privilege AI-agent surface; no install-time foreign-agent configuration mutation or data theft was confirmed. - **Evidence paths:** package.json, mcp/server.ts, dist/api/router.js, dist/agent/skill-learning/writer.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T15:26:35.223Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Nested MCP dependency installation and permission-bypassing Claude subprocess execution. - **Rationale:** The package has risky automatic MCP setup and a runtime Claude invocation that disables permissions. The inspected lifecycle scope is limited to its bundled MCP directory, so the evidence does not meet the threshold for malicious install-hook abuse. - **Files touched:** mcp/node\_modules, workspace/skills/\/SKILL.md ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** Its automatic postinstall runs Bun to install the bundled MCP project's dependencies., The bundled MCP server exposes channel, browser, app, API, memory, and agent modules., A gateway runtime helper launches Claude with permission checks disabled., The skill-learning writer can automatically create or replace agent-owned skill files. - **Evidence against:** The postinstall command is limited to the package's bundled mcp directory and does not edit Claude configuration., The package has no dependency on another version of itself., The runtime package-update endpoint requires an admin API key., No source evidence shows credential theft, covert exfiltration, or destructive install-time changes. ## Affected versions and remediation This report applies to @0xmaxma/claude-gateway@1.8.8. - Review the evidence and your use of @0xmaxma/claude-gateway@1.8.8 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.
