Adds an npx @wowok/agent-mcp launch entry to user-level AI-client configuration and may restart its process. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 2.2.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package silently provisions a Wowok MCP server across multiple unrelated AI-agent clients. It creates or modifies global agent configuration and launches a registry-fetched MCP package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-20T13:04:30.551Z - **Finished:** 2026-08-20T13:05:37.578Z - **Download time:** 517 ms - **Static scan time:** 478 ms - **AI review time:** 66031 ms - **Total time:** 67027 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package silently provisions a Wowok MCP server across multiple unrelated AI-agent clients. It creates or modifies global agent configuration and launches a registry-fetched MCP package. - **Trigger:** npm postinstall - **Impact:** Adds an npx @wowok/agent-mcp launch entry to user-level AI-client configuration and may restart its process. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-20T13:05:37.578Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad AI-agent configuration mutation plus global MCP installation - **Attack narrative:** On npm postinstall, the package defaults to eleven AI-client targets, copies skills, installs or upgrades @wowok/agent-mcp globally, and registers it through user-level MCP configuration. The inserted entries invoke npx -y @wowok/agent-mcp, allowing later registry resolution and execution by the affected clients. It then may terminate an existing Wowok MCP process to force a restart. This is unconsented mutation of a broad, foreign AI-agent control surface. - **Rationale:** The lifecycle script performs the concrete broad agent-control-surface mutation that the firewall policy reserves for blocking. Although the configuration is branded Wowok and no direct credential exfiltration appears in this package, automatic postinstall action across unrelated clients remains disqualifying. - **Files touched:** scripts/install.js, package.json, ~/.claude/settings.json, ~/.codex/config.toml, ~/.copilot/mcp-config.json, ~/.codeium/windsurf/mcp\_config.json, ~/.roo/mcp\_settings.json, ~/.kilocode/cli/global/settings/mcp\_settings.json - **Network endpoints:** npm registry via npm view/install ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall runs scripts/install.js automatically., Default install targets eleven AI coding clients., Postinstall auto-installs @wowok/agent-mcp globally., It writes MCP entries that launch the remote package via npx., It can terminate running wowok MCP processes after install. - **Evidence against:** Writes are limited to a named wowok MCP entry., No source evidence of credential harvesting or direct data exfiltration. ## Public findings ### 1.
