A dependency install can add an unconsented agent tool and execute its package through npx in the user's Claude Code environment. - **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:** 2.0.0 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package silently changes a user's global Claude Code configuration and installs agent content.

The resulting MCP entry can automatically fetch and run a separate package when Claude Code starts it. - **Trigger:** npm installation triggers postinstall. - **Impact:** A dependency install can add an unconsented agent tool and execute its package through npx in the user's Claude Code environment. - **Evidence paths:** package.json, bin/axe-skills.js - **Review source:** ai\_review - **Reviewed:** 2026-08-27T21:51:56.272Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall copies agent files and patches the global MCP server configuration. - **Attack narrative:** On npm installation, postinstall invokes the installer silently. It copies package-supplied commands and skills into global Claude Code directories, then writes an axe MCP server entry to ~/.claude.json. That entry uses npx -y to obtain and execute @axe/mcp when the MCP server is launched. This is an unconsented install-time mutation of a foreign AI-agent control surface and creates a remote executable extension path. - **Rationale:** The package performs unconsented postinstall mutation of global Claude Code files and injects an MCP server that automatically installs another package. This meets the blocking policy for foreign AI-agent control-surface mutation. - **Files touched:** ~/.claude/commands, ~/.claude/skills, ~/.claude.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** A postinstall hook runs the installer without user interaction., The installer writes AXE commands and skills into the user's Claude Code directories., It modifies the global Claude Code MCP configuration., The injected MCP entry runs npx with automatic installation of @axe/mcp. - **Evidence against:** The JavaScript installer contains no direct credential collection or HTTP request code., The observed mutation is limited to Claude Code paths and its MCP configuration. ## Public findings ### 1.
