AI clients can automatically start @wowok/agent-mcp with the user's permissions; the package also replaces skill content across many clients. - **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:** 3.0.3 - **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 automatically modifies multiple global AI-client skill and MCP control surfaces. It installs an external MCP package and configures clients to launch it through unpinned npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-13T04:20:07.434Z - **Finished:** 2026-09-13T04:21:06.473Z - **Download time:** 260 ms - **Static scan time:** 399 ms - **AI review time:** 58379 ms - **Total time:** 59039 ms The recorded confidence comes from the underlying analysis.

It installs an external MCP package and configures clients to launch it through unpinned npx. - **Trigger:** npm postinstall after package installation - **Impact:** AI clients can automatically start @wowok/agent-mcp with the user's permissions; the package also replaces skill content across many clients. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T04:21:06.473Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic broad AI-client configuration mutation and external MCP installation - **Attack narrative:** A normal npm installation invokes scripts/install.js without an explicit setup command. The script targets all supported AI clients by default, copies package-provided skills into their global directories, installs or upgrades @wowok/agent-mcp globally, and writes MCP entries that invoke it through npx. It then terminates matching MCP processes after an upgrade so IDEs can restart them. This is an unconsented install-time takeover of broad AI-agent control surfaces. - **Rationale:** The postinstall hook makes broad AI-agent configuration changes and installs a separately delivered, unpinned MCP runtime without user action. This meets the install-control-surface blocking policy despite no direct secret-exfiltration code in this snapshot. - **Files touched:** ~/.claude/skills, ~/.cursor/rules, ~/.windsurf/skills, ~/.codebuddy/skills, ~/.codex/skills, ~/.agents/skills, ~/.qoder/skills, ~/.roo/skills, ~/.cline/skills, ~/.kilo/skills, ~/.github/prompts, ~/.claude/settings.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs its installer automatically during npm postinstall., The installer defaults to all supported AI clients and copies skill files into their global configuration areas., Postinstall installs or upgrades a separate global MCP package and registers it in client configuration files., The registered MCP command uses npx with an unpinned package version, allowing later registry content to run in AI clients., When that MCP package changes, the installer terminates matching running MCP processes so IDEs restart them. - **Evidence against:** The inspected package contains no direct credential harvesting or explicit data-exfiltration endpoint., package.json has no runtime dependency on its own package name. ## Affected versions and remediation This report applies to @wowok/skills@3.0.3. - Avoid installing @wowok/skills@3.0.3. 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.
