Future AI-client sessions can launch @wowok/agent-mcp through npx. - **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:** 2.1.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm postinstall, the package installs a separate MCP package and registers it in user-level AI-client configuration. This is an unconsented broad agent-control-surface mutation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-16T01:31:08.832Z - **Finished:** 2026-08-16T01:33:09.792Z - **Download time:** 517 ms - **Static scan time:** 375 ms - **AI review time:** 120066 ms - **Total time:** 120960 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm postinstall, the package installs a separate MCP package and registers it in user-level AI-client configuration. This is an unconsented broad agent-control-surface mutation. - **Trigger:** npm postinstall - **Impact:** Future AI-client sessions can launch @wowok/agent-mcp through npx. - **Evidence paths:** package.json, scripts/install.js - **Review source:** ai\_review - **Reviewed:** 2026-08-16T01:33:09.792Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** auto-installs an MCP server and writes AI-client MCP configuration - **Attack narrative:** Installing this package runs scripts/install.js without a separate user command. Unless an opt-out environment variable is set, it globally installs or upgrades @wowok/agent-mcp and adds an npx launcher to several AI-agent client configurations, including Claude and Codex. That creates persistent execution of a separately fetched package in unrelated agent clients. - **Rationale:** The postinstall lifecycle hook performs unconsented mutation of broad, foreign AI-agent control surfaces and installs a remote dependency. This meets the blocking policy 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, ~/.copilot/mcp-config.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall invokes installer automatically., Installer registers an MCP server by default., It mutates multiple user-level AI-client configs., It installs/upgrades @wowok/agent-mcp globally via npm. - **Evidence against:** No credential harvesting or direct exfiltration found., No hard-coded network endpoint appears in source. ## Public findings ### 1.
