It deletes selected agent-related files and registers third-party MCP servers, including one configured with available AI-provider credentials. - **Trigger:** Installing the package globally through npm. - **Impact:** The install can remove user files, broaden Claude Code's tool and network access, and pass AI-provider credentials to a third-party MCP process. - **Evidence paths:** package.json, postinstall.js, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-28T14:41:12.019Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic postinstall execution mutates user-scoped AI-agent configuration and installs third-party MCP integrations. - **Attack narrative:** The npm postinstall hook detects a global installation and automatically starts the Unix installer with automatic and quiet flags. The installer defaults to Claude Code, deletes selected files under user AI-agent directories, and registers several third-party MCP servers at Claude user scope. When OpenAI or Anthropic credentials are present, it passes them to the browser-use MCP command. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Rationale:** This package combines an automatic npm lifecycle hook with silent deletion and broad third-party Claude MCP registration. The observed credential forwarding increases the impact beyond ordinary package-owned setup. - **Files touched:** postinstall.js, install.sh, $HOME/.claude/agents/.git, $HOME/.claude/.claude, $HOME/.cursorrules, $HOME/.instructions.md, $HOME/.codex/neocortex - **Network endpoints:** https://api.neocortex.sh/health, https://mcp.context7.com/mcp, https://mcp.figma.com/mcp ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs postinstall automatically., For global installs, postinstall launches the installer with automatic, quiet flags., The installer defaults to Claude Code and automatically removes user agent configuration files., It adds third-party user-scope MCP servers and forwards available OpenAI or Anthropic keys to one of them. - **Evidence against:** The automatic installer is limited to global installs; local installs only show usage., The package health check targets its own service endpoint, not a covert endpoint., No runtime dependency on its own package name was found in the manifest. ## Public findings ### 1.
