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. Source confirms a serious default exposure: the HTTP service binds to all interfaces while requests receive admin access when no key is configured. The autostart persistence path requires an explicit CLI command, so it does not establish unconsented installation-time persistence or malicious behavior. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-10-22T02:51:58.531Z - **Finished:** 2026-10-22T02:53:25.752Z - **Download time:** 520 ms - **Static scan time:** 3036 ms - **AI review time:** 83663 ms - **Total time:** 87221 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:** The server exposes an unauthenticated admin interface on all network interfaces by default. This is a serious remotely reachable control risk when the service is run without configuring an API key. - **Trigger:** A user starts the default HTTP server without setting an API key. - **Impact:** A network client may access server tools and operations with admin privileges; the exact consequences depend on the tools enabled and reachable CAD environment. - **Review source:** ai\_review - **Reviewed:** 2026-10-22T02:53:25.752Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The default listener host is 0.0.0.0 and the authorization middleware assigns admin access when no API keys are configured. - **Rationale:** Source confirms a serious default exposure: the HTTP service binds to all interfaces while requests receive admin access when no key is configured. The autostart persistence path requires an explicit CLI command, so it does not establish unconsented installation-time persistence or malicious behavior. - **Files touched:** package.json, dist/atlisp-mcp.js - **Network endpoints:** 0.0.0.0 ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The published CLI and main entrypoint both load dist/atlisp-mcp.js., The server defaults to HTTP on 0.0.0.0 with an empty API key., When no API keys are configured, the authorization middleware grants admin access to requests without credentials., The HTTP server listens on the configured host, exposing this unauthenticated admin path beyond localhost by default. - **Evidence against:** Autostart installation is activated by an explicit --install-autostart command; package installation alone does not create that persistence. ## Affected versions and remediation This report applies to @atlisp/mcp@1.9.4. - Review the evidence and your use of @atlisp/mcp@1.9.4 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.
