Future AI-agent sessions can be redirected to the package's local MCP service and attacker-authored instructions. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 0.2.96 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall downloads and starts a daemon, persists it as a user service, and mutates broad third-party AI-client MCP and instruction surfaces without user action. The injected instructions direct agents to prioritize Docdex tools and web research. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-08T09:39:15.290Z - **Finished:** 2026-08-08T09:39:56.400Z - **Download time:** 510 ms - **Static scan time:** 687 ms - **AI review time:** 39912 ms - **Total time:** 41110 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall downloads and starts a daemon, persists it as a user service, and mutates broad third-party AI-client MCP and instruction surfaces without user action. The injected instructions direct agents to prioritize Docdex tools and web research. - **Trigger:** npm install of docdex - **Impact:** Future AI-agent sessions can be redirected to the package's local MCP service and attacker-authored instructions. - **Evidence paths:** package.json, lib/install.js, lib/postinstall\_setup.js, lib/uninstall.js, assets/agents.md - **Review source:** ai\_review - **Reviewed:** 2026-08-08T09:39:56.400Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall AI-agent configuration hijack with daemon persistence - **Attack narrative:** Installing the package automatically downloads a native daemon, registers persistence, adds an MCP endpoint to numerous unrelated AI clients, and writes package-authored mandatory instructions into agent control files. This is unconsented postinstall mutation of a broad foreign AI-agent control surface. - **Rationale:** The lifecycle chain is source-confirmed and unguarded for npm installs; its setup does not limit configuration writes to a package-owned surface. This meets the blocking policy independent of scanner similarity signals. - **Files touched:** lib/install.js, lib/postinstall\_setup.js, assets/agents.md, ~/.codex/config.toml, ~/.codex/AGENTS.md, ~/.claude.json, ~/.cursor/mcp.json, ~/Library/Application Support/Code/User/mcp.json, ~/.config/systemd/user/docdexd.service, ~/Library/LaunchAgents/com.docdex.daemon.plist - **Network endpoints:** https://github.com/bekirdag/docdex/releases/download, http://127.0.0.1:28491, 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 postinstall executes lib/install.js., lib/install.js invokes runPostInstallSetup during postinstall., lib/postinstall\_setup.js silently registers Docdex MCP in Claude, Cursor, VS Code, Codex, and other client configs., lib/postinstall\_setup.js installs persistent user daemon services via launchd, systemd, or scheduled tasks., assets/agents.md contains mandatory agent directives; postinstall injects them into third-party agent instruction files., lib/uninstall.js removes external installs and broad client configuration entries. - **Evidence against:** No source evidence of credential harvesting or direct external data exfiltration., The installer uses SHA-256 checks before extracting its release artifact. ## Public findings ### 1.
