It also installs coercive agent instructions in the user’s Docdex directory. - **Trigger:** npm postinstall - **Impact:** Foreign AI clients gain a new default MCP endpoint and agent behavior is influenced automatically. - **Evidence paths:** package.json, lib/install.js, lib/postinstall\_setup.js, assets/agents.md, lib/uninstall.js, lib/update\_check.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:36:16.173Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad AI-agent MCP registration and persistent local-daemon setup - **Attack narrative:** Installing the package invokes install.js, which fetches and installs a platform binary, then invokes postinstall\_setup.js. That setup writes a Docdex MCP server into configuration files for multiple unrelated AI products, including Codex, and enables a user-level persistent daemon. The lifecycle script also copies agent instructions containing mandatory behavioral directives into ~/.docdex/agents.md. These actions occur without an explicit user setup command. - **Rationale:** The confirmed postinstall chain mutates a broad foreign AI-agent control surface and establishes persistence. This meets the block policy despite package-aligned loopback networking and release-download integrity checks. - **Files touched:** package.json, lib/install.js, lib/postinstall\_setup.js, assets/agents.md, lib/uninstall.js - **Network endpoints:** http://127.0.0.1:28491/sse, http://127.0.0.1:28491/v1/mcp, https://github.com/${repoSlug}/releases/download, https://registry.npmjs.org/docdex/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs lib/install.js on postinstall., lib/install.js unconditionally calls runPostInstallSetup after downloading/extracting a binary., lib/postinstall\_setup.js writes Docdex MCP entries into Claude, Cursor, Windsurf, VS Code, Codex, and other client configs., lib/postinstall\_setup.js registers and starts a persistent user daemon via launchd/systemd/schtasks., assets/agents.md contains mandatory directives that are installed to ~/.docdex/agents.md during postinstall. - **Evidence against:** Installer downloads from the declared GitHub release path and verifies SHA-256 metadata., MCP URLs are loopback-only: 127.0.0.1:28491., update\_check.js only contacts the npm registry during an interactive, enabled update check. ## Public findings ### 1.
