Future AI-client sessions launch @wowok/agent-mcp through npx across configured clients. - **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:** 2.1.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package writes skills and MCP launch configuration into multiple unrelated AI-client home directories. It then installs a separate MCP package globally and can terminate its running process for IDE restart. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-17T00:38:27.089Z - **Finished:** 2026-08-17T00:39:19.276Z - **Download time:** 505 ms - **Static scan time:** 423 ms - **AI review time:** 51257 ms - **Total time:** 52187 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package writes skills and MCP launch configuration into multiple unrelated AI-client home directories. It then installs a separate MCP package globally and can terminate its running process for IDE restart. - **Trigger:** npm postinstall without WOWOK\_SKILLS\_NO\_MCP enabled - **Impact:** Future AI-client sessions launch @wowok/agent-mcp through npx across configured clients. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-17T00:39:19.276Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** broad AI-agent config mutation plus automatic remote MCP installation - **Attack narrative:** Installing this package triggers scripts/install.js. Unless an opt-out environment variable is set, it targets all supported clients, writes their skill/MCP configuration, installs @wowok/agent-mcp globally, and registers it as an npx-launched MCP server. This creates persistent execution through foreign AI-agent control surfaces without an explicit setup command. - **Rationale:** The concrete postinstall behavior mutates broad foreign AI-agent configurations and introduces a remotely resolved MCP execution path. This meets the block boundary regardless of the absence of direct credential theft in this package. - **Files touched:** scripts/install.js, ~/.claude/settings.json, ~/.codebuddy/mcp.json, ~/.codeium/windsurf/mcp\_config.json, ~/.config/qoder/mcp-settings.json, ~/.roo/mcp\_settings.json, ~/.copilot/mcp-config.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes scripts/install.js automatically., Postinstall defaults to all supported AI-client targets., Installer writes MCP entries that execute npx @wowok/agent-mcp into foreign client configs., Lifecycle script globally installs/upgrades the MCP package and restarts its process. - **Evidence against:** No credential harvesting, exfiltration endpoint, eval, or unrelated file collection was found in inspected code. ## Public findings ### 1.
