A dependency installation changes multiple AI-agent control surfaces and causes them to run @wowok/agent-mcp. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 3.0.4 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. Installation silently writes skills and MCP registrations across broad user-level AI-agent directories. It configures those clients to launch a separately installed MCP package through npx and may restart its process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-15T17:59:49.111Z - **Finished:** 2026-09-15T18:00:58.230Z - **Download time:** 763 ms - **Static scan time:** 513 ms - **AI review time:** 67842 ms - **Total time:** 69119 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation silently writes skills and MCP registrations across broad user-level AI-agent directories. It configures those clients to launch a separately installed MCP package through npx and may restart its process. - **Trigger:** npm postinstall - **Impact:** A dependency installation changes multiple AI-agent control surfaces and causes them to run @wowok/agent-mcp. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-15T18:00:58.230Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic broad AI-agent configuration mutation and global MCP installation - **Attack narrative:** On npm installation, postinstall runs scripts/install.js without an explicit user command. By default it copies package skills into eleven AI-client directories, installs or upgrades @wowok/agent-mcp globally, and modifies client MCP configuration to invoke it with npx. This includes the Codex global configuration. If the MCP package changes, it terminates matching processes so the IDE restarts them. This is unconsented, broad mutation of foreign AI-agent control surfaces at install time. - **Rationale:** The package performs automatic postinstall mutation of numerous third-party AI-agent configurations and installs a separate executable MCP dependency. This is a concrete install-hook abuse chain under the stated policy. - **Files touched:** ~/.claude/skills, ~/.cursor/rules, ~/.windsurf/skills, ~/.codebuddy/skills, ~/.codex/skills, ~/.agents/skills, ~/.qoder/skills, ~/.roo/skills, ~/.cline/skills, ~/.kilo/skills, ~/.github/prompts, ~/.codex/config.toml, global npm installation of @wowok/agent-mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall hook runs the installer automatically., The installer targets eleven AI-client skill or prompt directories when no environment override is set., Postinstall automatically installs a global MCP package and registers it in client configurations., It adds an npx command for @wowok/agent-mcp to multiple AI-agent control surfaces, including Codex., The installer can terminate running MCP processes so IDEs restart them with the new server. - **Evidence against:** No credential harvesting or direct data-exfiltration code was found., No embedded network URL or payload downloader was found; package acquisition is delegated to npm. ## Affected versions and remediation This report applies to @wowok/skills@3.0.4. - Avoid installing @wowok/skills@3.0.4. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
