Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as agent extension risk** — Allowed by default with warning: install-time first-party agent extension setup was detected. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only agent extension risk - **Public report status:** Published - **Threat category:** Agent extension lifecycle risk - **Selected version:** 3.11.0 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. 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. This is not proven credential theft or foreign AI-client takeover, but automatic postinstall persistence and application replacement are substantial package lifecycle behavior. The package-owned scope and checksum verification support a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-09-01T18:55:38.502Z - **Finished:** 2026-09-01T18:57:04.205Z - **Download time:** 1012 ms - **Static scan time:** 3537 ms - **AI review time:** 81152 ms - **Total time:** 85703 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:** Installing the package automatically creates package-owned launch infrastructure and, on macOS, starts a persistent local daemon. It also checks GitHub releases and can update existing trace-mcp app bundles. - **Trigger:** npm install runs the postinstall lifecycle hook. - **Impact:** A package install can create an autostart service, restart its daemon, and modify matching installed app bundles without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall-control-plane.mjs, scripts/postinstall-app.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-01T18:57:04.205Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic user-level daemon persistence and package-owned app update. - **Rationale:** This is not proven credential theft or foreign AI-client takeover, but automatic postinstall persistence and application replacement are substantial package lifecycle behavior. The package-owned scope and checksum verification support a warning rather than a block. - **Files touched:** ~/.trace-mcp/launcher.env, ~/.trace-mcp/bin/trace-mcp, ~/Library/LaunchAgents/com.trace-mcp.server.plist, ~/Applications/trace-mcp.app, /Applications/trace-mcp.app - **Network endpoints:** api.github.com, 127.0.0.1 ### Review decision - **Verdict:** Suspicious - **Confidence:** 94.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall chain runs two scripts that change user-level state., The control-plane script writes an executable launcher under the user's trace-mcp directory., On macOS it creates and bootstraps a persistent LaunchAgent that runs the package's HTTP daemon., A separate postinstall script contacts GitHub release APIs and can replace installed trace-mcp app bundles. - **Evidence against:** The persistent service runs the package's own trace-mcp command and its health check is local only., The app updater requires a matching SHA-256 release asset before applying an update., No runtime dependency on trace-mcp itself is declared., No install-time code directly edits Claude, Codex, or other AI-client configuration files. ## Affected versions and remediation This report applies to trace-mcp@3.11.0. - Review the evidence and your use of trace-mcp@3.11.0 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.
