It deletes selected files and registers MCP tools and a remote service configuration without an interactive consent step. - **Trigger:** npm global installation, which runs postinstall. - **Impact:** It can remove user configuration artifacts and give Claude Code new user-scope tools that execute downloaded third-party packages or contact remote services. - **Evidence paths:** package.json, postinstall.js, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-30T22:56:28.790Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installer mutates AI-agent configuration and registers MCP commands. - **Attack narrative:** The postinstall hook detects global installation and launches install.sh with --yes, --quiet, and --skip-project. That path automatically cleans selected files beneath the user's Claude configuration, creates Neocortex agent configuration, and registers user-scope Claude MCP tools, including npx-fetched packages. It also configures the Neocortex remote endpoint. These are automatic mutations of a broad AI-agent control surface rather than an explicit user setup command. - **Rationale:** This is malicious install-hook abuse under the stated policy because an automatic npm lifecycle hook silently mutates a user's AI-agent configuration, deletes artifacts, and adds executable MCP integrations. The lack of a self-dependency does not mitigate that concrete behavior. - **Files touched:** $HOME/.claude/agents/.git, $HOME/.claude/.claude, $HOME/.claude/agents/neocortex, $HOME/.neocortex/config.json - **Network endpoints:** api.neocortex.sh, mcp.context7.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package declares an automatic postinstall hook., On global installation, the hook launches the shell installer with automatic, quiet Claude Code settings., The installer recursively deletes items in the user's Claude configuration, including an agent Git directory and unrelated legacy-labelled files., The installer adds several user-scope Claude MCP servers, including commands fetched with npx, without an interactive prompt in this lifecycle path., The installer configures a remote Neocortex service endpoint. - **Evidence against:** package.json has no runtime dependency on its own package name., The activation command sends a license or API key only when the user explicitly runs activation. ## Public findings ### 1.
