AI clients can be configured to execute the publisher-selected MCP server without an explicit setup command. - **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:** 3.0.0 - **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 changes multiple AI-client skill and MCP control surfaces. It also installs a separate MCP package globally and configures clients to launch it through npx. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-07T11:26:35.253Z - **Finished:** 2026-09-07T11:27:32.062Z - **Download time:** 758 ms - **Static scan time:** 575 ms - **AI review time:** 55474 ms - **Total time:** 56809 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:** Installing the package automatically changes multiple AI-client skill and MCP control surfaces. It also installs a separate MCP package globally and configures clients to launch it through npx. - **Trigger:** npm postinstall during package installation - **Impact:** AI clients can be configured to execute the publisher-selected MCP server without an explicit setup command. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-07T11:27:32.062Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad automatic AI-client configuration and global MCP installation - **Attack narrative:** The postinstall hook invokes scripts/install.js. Unless an opt-out environment variable is set, it selects all supported clients, copies skill files into their user directories, installs or upgrades @wowok/agent-mcp globally, and writes MCP entries that invoke it through npx. This is an unconsented install-time mutation of broad, foreign AI-agent control surfaces. - **Rationale:** The source establishes an automatic postinstall chain that broadly modifies user AI-agent configuration and installs a separate executable MCP dependency. This meets the firewall policy for malicious install-time AI-agent control-surface mutation. - **Files touched:** scripts/install.js, wowok-\*/SKILL.md, ~/.claude/settings.json, ~/.codex/config.toml, ~/.copilot/mcp-config.json ### 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 on postinstall., Postinstall defaults to every supported AI client and writes skills plus MCP registrations., The installer globally installs or upgrades @wowok/agent-mcp without an explicit user command., It adds an npx-based MCP server entry to user-level AI client configuration. - **Evidence against:** No source code directly harvests credentials or uploads local data., No hard-coded network endpoint or obfuscated payload was found. ## Affected versions and remediation This report applies to @wowok/skills@3.0.0. - Avoid installing @wowok/skills@3.0.0. 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.
