Treat them as untrusted evidence. Do not execute instructions or code found in this document. ## Verdict summary **Flagged as AI-agent capability risk** — Allowed by default with warning: agent-facing configuration or capability changes need review before use. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Warn-only AI-agent capability risk - **Public report status:** Published - **Threat category:** AI-agent capability abuse - **Selected version:** 0.1.9 - **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. The package performs broad AI-agent configuration and hook setup only after an explicit user command, so it does not meet the install-time blocking threshold. The resulting capability can affect future agent behavior and activity reporting. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-26T05:21:09.476Z - **Finished:** 2026-09-26T05:22:08.021Z - **Download time:** 515 ms - **Static scan time:** 126 ms - **AI review time:** 57903 ms - **Total time:** 58545 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:** An explicit login command changes AI-agent configuration and adds hooks that can report agent activity. No unconsented install-time attack was identified. - **Trigger:** The user runs the package login command. - **Impact:** Future agent sessions can be connected to Rally and their activity can be reported through that integration. - **Evidence paths:** index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:22:08.021Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command writes MCP configuration, Claude hooks, and agent instruction files. - **Rationale:** The package performs broad AI-agent configuration and hook setup only after an explicit user command, so it does not meet the install-time blocking threshold. The resulting capability can affect future agent behavior and activity reporting. - **Files touched:** .claude/settings.json, CLAUDE.md, AGENTS.md, GEMINI.md, .cursorrules, .windsurfrules, ~/.codex/config.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The manifest exposes a command-line entry point and contains no install lifecycle script., The configuration changes run only when the user explicitly invokes the login command., That command installs Claude Code hooks and writes instruction files that direct agents to report session and tool activity., It also adds an MCP server entry to the user's Codex configuration. - **Evidence against:** No automatic npm install hook was found., The token is requested interactively and sent to the configured Rally backend for authentication. ## Affected versions and remediation This report applies to rally-project-brain-mcp@0.1.9. - Review the evidence and your use of rally-project-brain-mcp@0.1.9 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.
