On global npm installation, the package silently modifies detected Claude, Devin, Cursor, and Codex agent configuration. It registers its MCP server and persistent lifecycle commands that run during agent sessions. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-25T17:00:54.777Z - **Finished:** 2026-08-25T17:01:39.387Z - **Download time:** 510 ms - **Static scan time:** 2259 ms - **AI review time:** 41840 ms - **Total time:** 44610 ms ## Security analysis ### Published attack-surface review - **Summary:** On global npm installation, the package silently modifies detected Claude, Devin, Cursor, and Codex agent configuration. It registers its MCP server and persistent lifecycle commands that run during agent sessions. - **Trigger:** \`npm install -g remem-mcp\` on a non-CI machine with a supported agent directory. - **Impact:** Future agent sessions execute package-controlled commands and load its MCP server without an explicit setup command. - **Evidence paths:** package.json, scripts/postinstall.js, dist/index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-25T17:01:39.387Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-launched agent configuration and lifecycle-hook registration - **Attack narrative:** The postinstall hook detects global installation and existing agent directories, then invokes \`setup\` silently. Setup alters multiple unrelated AI-agent configuration surfaces, registering \`npx -y remem-mcp\` and lifecycle hooks that execute on session start, prompt submission, tool use, stop, and session end. This is unconsented install-time persistence across broad agent control surfaces. - **Rationale:** The source establishes an unconsented postinstall chain that mutates foreign AI-agent configs and installs recurring commands. This meets the firewall block boundary despite global-install and CI guards. - **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:** Global-install postinstall automatically launches \`setup\` when agent directories exist., \`setup\` registers the MCP server, installs lifecycle hooks, and installs skills without user confirmation., It writes agent configuration that executes \`npx -y remem-mcp\` on future agent use., Codex hooks are added for startup, tool use, prompt submission, stop, and session end. - **Evidence against:** The install hook is gated to global installs and skips CI., No fixed third-party exfiltration endpoint was found; the optional proxy defaults to OpenAI. ## Public findings ### 1.
