Multiple AI clients can be configured to invoke @wowok/agent-mcp without a separate user command or per-client consent. - **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:** 3.0.2 - **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 broad, foreign AI-agent skill and MCP control surfaces. It globally installs a separate MCP package 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:** 2026-09-13T02:28:56.350Z - **Finished:** 2026-09-13T02:29:52.816Z - **Download time:** 1036 ms - **Static scan time:** 379 ms - **AI review time:** 55051 ms - **Total time:** 56466 ms The recorded confidence comes from the underlying analysis.

It globally installs a separate MCP package and configures clients to launch it through npx. - **Trigger:** npm postinstall during package installation. - **Impact:** Multiple AI clients can be configured to invoke @wowok/agent-mcp without a separate user command or per-client consent. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T02:29:52.816Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic cross-client skill deployment, MCP configuration injection, global package installation, and process restart. - **Attack narrative:** On installation, package.json runs scripts/install.js. Unless an environment override is supplied, the script targets all supported AI clients and copies package skill content into their user-level directories. It then installs or upgrades @wowok/agent-mcp globally, adds MCP entries that run it via npx, and terminates an existing MCP process so an IDE restarts it. This is an unconsented postinstall mutation of broad foreign AI-agent control surfaces. - **Rationale:** The source implements the policy-defined malicious chain: an automatic install lifecycle broadly mutates AI-agent controls and installs/configures a separate executable MCP dependency. The absence of direct secret theft does not neutralize this concrete control-surface takeover. - **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 ### 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., With no target override, installation selects every supported AI client., It writes skill files into multiple unrelated AI-client directories., It installs or upgrades @wowok/agent-mcp globally, registers it in client MCP configurations, and restarts its process. - **Evidence against:** No credential harvesting or direct data-exfiltration code was found in the inspected entry points., No self-dependency or obfuscated payload was present in package.json. ## Affected versions and remediation This report applies to @wowok/skills@3.0.2. - Avoid installing @wowok/skills@3.0.2. 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.
