A dependency installation changes multiple AI-agent control surfaces and causes them to run @wowok/agent-mcp via npx. - **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:** 3.0.1 - **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. Installing the package triggers broad mutation of AI-agent skill and MCP configuration. It also installs a separate MCP package globally and restarts its process. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T04:00:12.646Z - **Finished:** 2026-09-13T04:01:15.547Z - **Download time:** 777 ms - **Static scan time:** 427 ms - **AI review time:** 61696 ms - **Total time:** 62901 ms The recorded confidence comes from the underlying analysis.

It also installs a separate MCP package globally and restarts its process. - **Trigger:** npm postinstall - **Impact:** A dependency installation changes multiple AI-agent control surfaces and causes them to run @wowok/agent-mcp via npx. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T04:01:15.547Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic cross-client skill deployment, MCP registration, global package installation, and process restart - **Attack narrative:** On npm postinstall, the package targets all supported AI clients by default, copies skills into their user directories, installs or upgrades @wowok/agent-mcp globally, writes MCP entries that invoke it through npx, and may terminate the existing MCP process for restart. These changes occur without an explicit setup command and affect broad, foreign agent control surfaces. - **Rationale:** This is a concrete unconsented postinstall mutation of broad AI-agent control surfaces, combined with automatic installation of a separate registry package and process restart. It meets the install-hook abuse blocking boundary even though the inspected source does not itself harvest credentials. - **Files touched:** scripts/install.js, wowok-\*/SKILL.md, ~/.claude/settings.json, ~/.codex/config.toml, ~/.codeium/windsurf/mcp\_config.json, ~/.copilot/mcp-config.json, VS Code globalStorage MCP settings ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The postinstall lifecycle automatically runs the installer., The default target list writes skills into eleven unrelated AI-client directories., Postinstall installs or upgrades @wowok/agent-mcp globally from the npm registry., It registers that MCP server in client configuration, including Codex, without an interactive command., It terminates matching MCP processes so IDEs restart them with the new configuration. - **Evidence against:** package.json has no dependencies, so there is no runtime self-dependency chain., The library entrypoint only exports skill metadata and reads local skill files; it does not invoke the installer., No credential harvesting or direct data-exfiltration code was found in the inspected JavaScript. ## Affected versions and remediation This report applies to @wowok/skills@3.0.1. - Avoid installing @wowok/skills@3.0.1. 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.
