A dependency installation changes foreign AI-agent control surfaces and causes later agent use to launch package-provided or remotely resolved tools. - **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:** 2.5.98 - **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 dependency silently modifies consumer-project AI-agent configuration. It activates a JoyCode agent and registers MCP servers for JoyCode and Cursor, including an unpinned npx-loaded Playwright MCP. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-08T12:49:13.883Z - **Finished:** 2026-08-08T12:50:05.935Z - **Download time:** 754 ms - **Static scan time:** 679 ms - **AI review time:** 50617 ms - **Total time:** 52052 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the dependency silently modifies consumer-project AI-agent configuration. It activates a JoyCode agent and registers MCP servers for JoyCode and Cursor, including an unpinned npx-loaded Playwright MCP. - **Trigger:** npm postinstall when installed as a project dependency - **Impact:** A dependency installation changes foreign AI-agent control surfaces and causes later agent use to launch package-provided or remotely resolved tools. - **Evidence paths:** package.json, bin/postinstall.js, lib/install.js, assets/mcp/proto-version-server.js, assets/mcp/line-repos-server.js - **Review source:** ai\_review - **Reviewed:** 2026-08-08T12:50:05.935Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** automatic project AI-agent and MCP configuration mutation - **Attack narrative:** On npm installation, postinstall locates the consuming project and calls install with JoyCode, Cursor, agent, and version options enabled. The installer copies and activates an agent, rewrites both project MCP configuration files, and registers an unpinned npx @playwright/mcp@latest command. This is unconsented postinstall mutation of foreign AI-agent control surfaces, not merely an explicit scaffold command. - **Rationale:** The package’s primary assets appear package-aligned, but its automatic postinstall performs broad, active AI-agent and MCP configuration changes in every consuming project. That concrete install-time control-surface mutation meets the block boundary. - **Files touched:** .joycode/agent.json, .joycode/agents/德邦PRD产品经理.md, .joycode/modes/rules-zczvigx-/, .joycode/mcp.json, .cursor/mcp.json, mcp/proto-version-server.js, mcp/line-repos-server.js, package.json - **Network endpoints:** https://registry.npmjs.org/@deppon%2fpm-toolkit/latest ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall automatically., bin/postinstall.js invokes install() in the consumer project by default., lib/install.js writes active .joycode/agent.json and agent content., lib/install.js overwrites .joycode/.cursor mcp.json entries., MCP config registers npx -y @playwright/mcp@latest., Postinstall defaults enable JoyCode, Cursor, agents, and version service. - **Evidence against:** No credential harvesting or exfiltration found., Network lookup is limited to npm registry version metadata., Bundled MCP servers are local stdio project tools., The flagged Python test is ordinary unittest source; .pyc files are Python bytecode cache. ## Public findings ### 1.
