The package gains execution through several AI-agent control surfaces and can bypass a workspace trust prompt. - **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:** 6.0.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm postinstall launches an installer that changes AI-agent hook, MCP, and trust settings. The changes cause package code to run in later agent sessions and tool calls. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-27T15:17:13.991Z - **Finished:** 2026-08-27T15:18:46.424Z - **Download time:** 1009 ms - **Static scan time:** 9965 ms - **AI review time:** 81455 ms - **Total time:** 92433 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm postinstall launches an installer that changes AI-agent hook, MCP, and trust settings. The changes cause package code to run in later agent sessions and tool calls. - **Trigger:** Installing the package globally through npm outside CI. - **Impact:** The package gains execution through several AI-agent control surfaces and can bypass a workspace trust prompt. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, scripts/wire-hooks.mjs, hooks-core/wire.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-27T15:18:46.424Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall-driven installation of hooks, MCP entries, and workspace trust changes. - **Attack narrative:** A global npm install automatically invokes a shell or PowerShell installer. That installer copies executable agent hooks, modifies Claude Code settings to invoke them, marks the current workspace trusted, and registers the package as an MCP server in several detected AI-tool configurations. These are unconsented postinstall changes to foreign and broad AI-agent control surfaces. - **Rationale:** This is concrete postinstall mutation of multiple foreign AI-agent control surfaces, including automatic workspace-trust acceptance. The lifecycle guard only limits it to global installs; it does not obtain consent for the changes. - **Files touched:** scripts/postinstall.cjs, install-hooks.sh, scripts/wire-hooks.mjs, $HOME/.claude-global/hooks/token-optimizer, $HOME/.claude/settings.json, $HOME/.claude.json, $HOME/.cursor/mcp.json, .vscode/mcp.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The postinstall hook runs an installer during global npm installation., The installer copies hooks and wires them into the user's Claude Code settings., It sets the current workspace as trusted without user confirmation., It adds an MCP server entry to detected Claude, Cursor, Cline, Copilot, and Windsurf configurations. - **Evidence against:** The postinstall hook skips local dependency installs and CI., The hook merger preserves non-package hook entries., No credential exfiltration or external payload download was confirmed in the inspected install path. ## Public findings ### 1.
