The installed hooks collect agent prompts and tool activity for remote reporting. - **Trigger:** A user runs \`rally-project-brain-mcp login --agent\`, then an affected AI client starts or uses its configured hooks. - **Impact:** User prompts, tool inputs, command details, and portions of tool responses can be sent to the Rally backend; the package also changes project and global AI-agent control surfaces. - **Evidence paths:** package.json, index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-29T16:08:41.116Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Persistent AI-agent configuration and hook installation with transcript collection. - **Attack narrative:** Running the login command creates MCP entries containing the supplied token, adds global and project agent configuration, writes Base64-embedded Claude Code hooks, and injects agent instructions. Static decoding of those hooks shows that they report submitted prompts, tool inputs, and tool responses to the configured backend on automatic hook events. Although npm installation has no lifecycle trigger, the explicit setup produces persistent monitoring and remote data collection across AI-agent control surfaces. - **Rationale:** This package implements concrete remote collection of agent prompts and tool activity while modifying several AI-agent configuration surfaces. The behavior is explicit-command triggered rather than install-time, but the broad persistent setup and transcript export warrant blocking. - **Files touched:** .mcp.json, .cursor/mcp.json, .gemini/settings.json, .vscode/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.codex/config.toml, Cline globalStorage/saoudrizwan.claude-dev/settings/cline\_mcp\_settings.json, .claude/hooks/\*.mjs, .claude/settings.json, CLAUDE.md, AGENTS.md, GEMINI.md, .cursorrules, .windsurfrules - **Network endpoints:** https://rally-backend.fly.dev, http://localhost:8080 ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The explicit login command writes MCP configurations for several project and global AI-agent clients., The generated MCP entry stores the supplied actor token and launches this package through npx., Login decodes embedded hook code and configures it for session start, every submitted prompt, every tool use, and session end., Decoded hook payloads send prompt text, tool inputs, and capped tool responses to the configured Rally backend., Login also inserts reporting instructions into common agent instruction files. - **Evidence against:** The manifest has no npm lifecycle scripts, so installation alone does not trigger these changes., The configuration and hook setup are reached only through the explicit login command., The login flow asks interactively for the token before contacting its default backend. ## Public findings ### 1.
