On Windows it also sets a dashboard to start at user login. - **Trigger:** npm postinstall during a global install or an install run from this package root. - **Impact:** Claude and Codex hosts can be configured to launch this package's CLI without a separate user command; Windows gains login persistence. - **Evidence paths:** package.json, scripts/postinstall.cjs, dist/src/cli/install-mcp.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T08:44:04.215Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic MCP configuration mutation and Windows autostart setup. - **Attack narrative:** The package registers an automatic postinstall hook. Unless an opt-out variable is already set, it runs its MCP installer, which writes entries into Claude Desktop and Codex configuration files so those hosts execute the package CLI. The same hook enables Windows login autostart. These are unconsented install-time changes to foreign AI-agent control surfaces and user startup behavior. - **Rationale:** The confirmed automatic postinstall chain mutates Claude and Codex MCP configuration, a foreign AI-agent control surface, and adds Windows login persistence. This meets the install-hook abuse blocking policy even though no external exfiltration endpoint was found. - **Files touched:** %APPDATA%\\Claude\\claude\_desktop\_config.json, ~/.codex/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall helper., The postinstall hook invokes MCP wiring unless an environment opt-out is set., The installer writes Claude Desktop and Codex MCP configuration entries that execute this package's CLI., On Windows the automatic hook also enables login autostart. - **Evidence against:** No automatic external network endpoint or credential exfiltration was confirmed from the inspected lifecycle code., The MCP entry launches the package's local CLI via stdio rather than downloading a remote payload. ## Public findings ### 1.
