It installs a high-permission agent and third-party MCP commands without an explicit setup command. - **Trigger:** Installing the package globally through npm. - **Impact:** It can expand an AI agent's execution and network capabilities in the user's account. - **Evidence paths:** package.json, postinstall.js, install.sh, targets-stubs/claude-code/neocortex.md - **Review source:** ai\_review - **Reviewed:** 2026-08-27T23:47:43.088Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launches a quiet installer that writes Claude files and registers user-scope MCP servers. - **Attack narrative:** On global npm installation, the postinstall hook starts install.sh with automatic confirmation. The script creates a Claude Code agent directory and registers user-scope MCP servers, including npx-delivered tools and remote endpoints. The shipped Claude agent requests bypassed permissions and unrestricted Bash. These are changes to a foreign AI-agent control surface made during installation rather than through a separate user-invoked setup command. - **Rationale:** This is concrete unconsented postinstall mutation of the user's Claude Code control surface, including high-permission agent content and MCP registration. That meets the package firewall block policy even though direct credential exfiltration was not confirmed. - **Files touched:** postinstall.js, install.sh, targets-stubs/claude-code/neocortex.md, ~/.claude/agents/neocortex - **Network endpoints:** https://mcp.context7.com/mcp, https://mcp.figma.com/mcp, https://api.neocortex.sh/health ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs postinstall.js during npm installation., For global installs, postinstall automatically launches the installer with non-interactive yes and quiet flags., The installer defaults to Claude Code and creates a user-level Claude agent directory., It automatically adds several user-scope Claude MCP servers, including commands fetched through npx., The installed Claude agent requests bypassed permissions and full Bash access. - **Evidence against:** The inspected lifecycle code does not show credential exfiltration., The compatibility request only targets the package vendor health endpoint. ## Public findings ### 1.
