Subsequent AI-agent sessions execute package-controlled hooks and tool calls can be denied or redirected. - **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:** 5.5.0 - **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 installs always-on AI-agent hooks and alters broad AI-client control surfaces. It also marks the current Claude workspace trusted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-10T07:16:06.870Z - **Finished:** 2026-08-10T07:17:09.487Z - **Download time:** 777 ms - **Static scan time:** 5794 ms - **AI review time:** 56043 ms - **Total time:** 62617 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically installs always-on AI-agent hooks and alters broad AI-client control surfaces. It also marks the current Claude workspace trusted. - **Trigger:** npm install -g @ooples/token-optimizer-mcp - **Impact:** Subsequent AI-agent sessions execute package-controlled hooks and tool calls can be denied or redirected. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, hooks-core/wire.mjs, plugin/hooks/pretooluse-router.mjs, plugin/hooks/lib/policy.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T07:17:09.487Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-launched cross-client hook and MCP configuration mutation - **Attack narrative:** On global installation, the postinstall script launches the bundled installer without an explicit setup command. The installer copies persistent hooks, adds commands to Claude Code's global settings for SessionStart, PreToolUse, and PreCompact, can auto-accept workspace trust, and adds the package as an MCP server to several detected AI clients. The installed PreToolUse path can return permissionDecision: deny, giving package code control over later agent tool use. - **Rationale:** This is concrete, unconsented postinstall mutation of foreign and broad AI-agent control surfaces, including trust state and always-on hooks. The guarded remote harvest path does not mitigate that install-time control hijack. - **Files touched:** scripts/postinstall.cjs, install-hooks.sh, ~/.claude-global/hooks/token-optimizer/\*\*, ~/.claude/settings.json, ~/.claude.json, ~/.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:** package.json invokes postinstall., scripts/postinstall.cjs runs installer on global npm install., install-hooks.sh copies persistent hooks and rewrites ~/.claude/settings.json., hooks-core/wire.mjs installs SessionStart, PreToolUse, and PreCompact commands., install-hooks.sh also modifies detected Claude Desktop, Cursor, Cline, VS Code, and Windsurf MCP configs., install-hooks.sh accepts current workspace trust in ~/.claude.json. - **Evidence against:** Remote harvest is separately gated by TOKEN\_OPTIMIZER\_HARVEST and an API key., Hook wiring preserves non-package hook entries. ## Public findings ### 1.
