The package can alter Claude agent configuration and cause later agent sessions to use vendor and third-party MCP integrations without an explicit setup command. - **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:** 4.60.31 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm install automatically runs an installer that modifies the user's Claude Code control surface. It creates a vendor thin-client configuration and adds user-scoped MCP servers, some resolved through latest third-party packages. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-31T14:48:16.721Z - **Finished:** 2026-08-31T14:49:25.690Z - **Download time:** 764 ms - **Static scan time:** 2439 ms - **AI review time:** 65765 ms - **Total time:** 68969 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically runs an installer that modifies the user's Claude Code control surface. It creates a vendor thin-client configuration and adds user-scoped MCP servers, some resolved through latest third-party packages. - **Trigger:** Installing the package globally through npm triggers postinstall. - **Impact:** The package can alter Claude agent configuration and cause later agent sessions to use vendor and third-party MCP integrations without an explicit setup command. - **Evidence paths:** package.json, postinstall.js, install.sh - **Review source:** ai\_review - **Reviewed:** 2026-08-31T14:49:25.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic lifecycle-driven AI-agent configuration and MCP registration. - **Attack narrative:** A global npm installation executes postinstall, which launches install.sh or install.ps1 with automatic, quiet options. The Unix installer selects Claude Code by default, creates files in the user's Claude agent directory, writes a remote thin-client configuration, removes selected legacy AI-tool files, and registers user-scoped MCP servers. Several MCP registrations invoke latest third-party packages. These changes occur as part of npm lifecycle execution rather than an explicit user setup command. - **Rationale:** This is unconsented postinstall mutation of a broad AI-agent control surface, including automatic MCP registration and remote thin-client setup. The global-install guard does not make the lifecycle mutation user-invoked. - **Files touched:** $HOME/.claude, $HOME/.claude/agents/neocortex, $HOME/.neocortex/config.json, $HOME/.codex/neocortex - **Network endpoints:** api.neocortex.sh, 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 declares a postinstall lifecycle hook., On global installation, postinstall silently starts the Unix or Windows installer with automatic and quiet flags., The installer defaults to the Claude Code target and automatically creates and configures files under the user's Claude agent directory., The automatic installer adds user-scoped Claude MCP servers, including commands that fetch latest third-party packages., The installer writes a thin-client configuration pointing to the vendor API and removes selected files under AI-tool directories. - **Evidence against:** The automatic installer is limited to global installs; local installs display a usage message., No runtime dependency on this package's own name was found in package.json., The compatibility request has a fixed vendor host and a five-second timeout. ## Public findings ### 1.
