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. Login is an explicit command, but it broadly rewrites agent control surfaces and installs hooks that forward prompts and tool calls to the package backend. There is no install-time hook, so this is a guarded agent capability rather than an unconsented install hijack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 82.0% - **Started:** 2026-09-26T05:21:13.236Z - **Finished:** 2026-09-26T05:22:56.961Z - **Download time:** 252 ms - **Static scan time:** 170 ms - **AI review time:** 103303 ms - **Total time:** 103725 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 login command writes several AI client configs and Claude hooks. After that, the hooks forward prompts and tool activity to the configured Rally backend. npm install does not run this path. - **Trigger:** A user runs rally-project-brain-mcp login and pastes an agent token. - **Impact:** Later sessions can load this package and send conversation and tool data to the Rally backend. Global Codex and Windsurf configs are also updated. - **Evidence paths:** index.mjs, .claude/hooks/user-prompt-submit.mjs, .claude/hooks/post-tool-use.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T05:22:56.961Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The command merges an npx MCP server entry into project and global client configs, installs Claude hook scripts, and those hooks POST prompts and tool payloads to RALLY\_BACKEND\_URL or https://rally-backend.fly.dev. - **Rationale:** Login is an explicit command, but it broadly rewrites agent control surfaces and installs hooks that forward prompts and tool calls to the package backend. There is no install-time hook, so this is a guarded agent capability rather than an unconsented install hijack. - **Files touched:** .mcp.json, .cursor/mcp.json, .gemini/settings.json, .vscode/mcp.json, .claude/settings.json, .claude/hooks/, ~/.codeium/windsurf/mcp\_config.json, ~/.codex/config.toml, CLAUDE.md, AGENTS.md - **Network endpoints:** https://rally-backend.fly.dev ### Review decision - **Verdict:** Suspicious - **Confidence:** 82.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The login subcommand writes project MCP configs, global Windsurf and Codex agent configs, and Claude Code hook settings., Hooks installed by that command POST the user prompt and tool-call details to the Rally backend URL from the environment., package.json only declares a bin and dependencies, with no install lifecycle scripts. - **Evidence against:** The writer runs only when the user passes the login argument and pastes an agent token., Requests use that token against the Rally project backend, not an unrelated host., The default process is a stdio MCP server and does not write agent configs on import. ## Affected versions and remediation This report applies to rally-project-brain-mcp@0.1.13. - Review the evidence and your use of rally-project-brain-mcp@0.1.13 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.
