Persistent execution path for @wowok/agent-mcp is added to multiple AI-agent control surfaces, including Codex. - **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:** 2.2.2 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package writes skills and MCP configuration across AI clients by default. It globally installs and registers a separately resolved MCP package, enabling it to run through those clients. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-22T00:16:35.479Z - **Finished:** 2026-08-22T00:17:32.792Z - **Download time:** 510 ms - **Static scan time:** 484 ms - **AI review time:** 56317 ms - **Total time:** 57313 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package writes skills and MCP configuration across AI clients by default. It globally installs and registers a separately resolved MCP package, enabling it to run through those clients. - **Trigger:** npm postinstall of @wowok/skills@2.2.2 without WOWOK\_SKILLS\_NO\_MCP set - **Impact:** Persistent execution path for @wowok/agent-mcp is added to multiple AI-agent control surfaces, including Codex. - **Evidence paths:** package.json, scripts/install.js, dist/cli.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T00:17:32.792Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad AI-client config mutation plus global npm MCP installation - **Attack narrative:** Installing the package triggers scripts/install.js. Unless an opt-out variable is set, it targets all supported AI clients, installs or upgrades @wowok/agent-mcp globally, writes MCP configuration entries that run it through npx, and may terminate an existing MCP process for restart. This is unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The lifecycle hook performs broad AI-client configuration and executable MCP registration by default, rather than limiting setup to an explicit user command or a package-owned surface. No source evidence offsets this install-time control-surface behavior. - **Files touched:** scripts/install.js, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codeium/windsurf/mcp\_config.json, ~/.copilot/mcp-config.json, ~/.roo/mcp\_settings.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes scripts/install.js automatically., Default lifecycle target list covers 11 AI clients., Postinstall installs/upgrades @wowok/agent-mcp globally., It writes MCP entries that invoke npx -y @wowok/agent-mcp., It modifies global Codex configuration and can restart the MCP process. - **Evidence against:** No credential harvesting or HTTP exfiltration code found in inspected entrypoints., MCP setup has an environment-variable opt-out, but it is not the default. ## Public findings ### 1.
