It registers this MCP server and persistent command hooks for agent and tool lifecycle events. - **Trigger:** \`npm install -g remem-mcp\` on a non-CI host with a detected Claude, Devin, Cursor, or Codex configuration - **Impact:** Subsequent agent sessions and Bash/exec tool events invoke package-controlled commands. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-14T12:35:10.645Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-driven foreign AI-agent configuration and hook injection - **Attack narrative:** The package's npm postinstall runs automatically for global installation, detects installed AI-agent configuration directories, and silently runs \`setup\`. Setup registers remem-mcp as an MCP server and writes lifecycle command hooks into Claude, Devin, Cursor, and Codex configuration files. The hooks run package commands during session start/end, compaction, stop, and Bash/exec tool use. This is unconsented install-time mutation of foreign AI-agent control surfaces, creating persistence and command execution on later agent activity. - **Rationale:** Direct inspection confirms the critical behavior is the guarded but automatic postinstall mutation of multiple foreign AI-agent control surfaces. The scanner's fixed-gateway credential-exfiltration claim was not confirmed, but the install-time hook injection independently meets the block boundary. - **Files touched:** scripts/postinstall.js, dist/index.js, ~/.claude.json, ~/.claude/settings.json, ~/.config/devin/mcp\_config.json, ~/.config/devin/config.json, ~/.cursor/mcp.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** npm postinstall automatically launches \`dist/index.js setup\` on global installs when agent directories exist., Setup registers the MCP server in Claude Code, Devin, Cursor, and existing Codex configurations., Setup installs command hooks for agent lifecycle and Bash/exec tool events., The installed hooks invoke this package via its binary or \`npx --prefer-offline -y remem-mcp\`. - **Evidence against:** No fixed third-party credential-exfiltration endpoint was found; the LLM request defaults to OpenAI and uses a user-supplied API key., The lifecycle mutation is guarded to global installs with a detected agent configuration. ## Public findings ### 1.
