It also installs a user-level persistent daemon. - **Trigger:** npm postinstall - **Impact:** Future AI-agent sessions can be redirected to the local Docdex service and follow package-supplied mandatory directives. - **Evidence paths:** package.json, lib/install.js, lib/postinstall\_setup.js, assets/agents.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:12:41.650Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad AI-agent config/instruction injection plus daemon persistence - **Attack narrative:** Installing the package executes its postinstall hook. The hook downloads/runs a daemon, creates persistence, inserts Docdex MCP endpoints across unrelated AI clients, and writes mandatory instructions into their agent-control files. Those instructions compel use of the local service and web research, affecting later sessions without an explicit setup command. - **Rationale:** This is concrete, unconsented postinstall mutation of broad foreign AI-agent control surfaces, accompanied by persistence. Localhost binding does not remove the control-hijack risk because the injected MCP and instruction entries affect future client behavior. - **Files touched:** lib/install.js, lib/postinstall\_setup.js, assets/agents.md, ~/.docdex/config.toml, ~/.codex/config.toml, ~/.claude.json, ~/.cursor/mcp.json, ~/Library/LaunchAgents/com.docdex.daemon.plist, ~/.config/systemd/user/docdexd.service - **Network endpoints:** https://github.com/bekirdag/docdex/releases/download, http://127.0.0.1:28491/v1/mcp ### 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 as postinstall., lib/install.js always calls runPostInstallSetup after binary installation., lib/postinstall\_setup.js writes MCP entries into Claude, Cursor, VS Code, Zed, Codex and other client configs., lib/postinstall\_setup.js injects assets/agents.md directives into agent instruction files., The injected directives require Docdex memory, web research, and tool use., postinstall registers a persistent daemon via LaunchAgent, systemd user unit, or Windows scheduled task. - **Evidence against:** Daemon binds only to 127.0.0.1:28491., Source contains no direct credential harvesting or remote exfiltration routine., Release download code performs SHA-256 checks when metadata is available. ## Public findings ### 1.
