These hooks execute package commands during agent sessions and tool use. - **Trigger:** npm install -g remem-mcp on a machine with a supported agent directory. - **Impact:** Persistence and execution in Claude, Devin, Cursor, Codex, and generic agent control surfaces. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T17:00:23.302Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven foreign agent MCP, hook, and skill registration. - **Attack narrative:** The postinstall hook runs automatically for global installs, detects AI-agent directories, and invokes setup without user confirmation. Setup registers the package as an MCP server, installs commands for session and Bash/exec lifecycle events, copies a skill into agent directories, and appends Codex configuration recommending broad sandbox access. This is unconsented postinstall mutation of foreign AI-agent control surfaces. - **Rationale:** Source confirms a guarded but automatic global postinstall chain that persists executable hooks across multiple third-party agent configurations. This meets the blocking policy for unconsented install-time mutation of a broad foreign AI-agent control surface. - **Files touched:** scripts/postinstall.js, dist/index.js, ~/.claude.json, ~/.claude/settings.json, ~/.cursor/mcp.json, ~/.config/devin/mcp\_config.json, ~/.config/devin/config.json, ~/.codex/config.toml, ~/.agents/skills/remem-mcp/SKILL.md ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global-install postinstall silently invokes setup when agent directories exist., Setup automatically registers MCP servers, hooks, and skills in Claude, Devin, Cursor, Codex, and .agents., Installed hooks run remem-mcp commands on agent lifecycle and Bash/exec events., Codex configuration is appended to request broad sandbox access. - **Evidence against:** Postinstall skips non-global installs and CI., Observed LLM request uses a user-supplied key and defaults to api.openai.com. ## Public findings ### 1.
