The hooks run on future sessions and tool calls, including PreToolUse. - **Trigger:** npm install -g @ooples/token-optimizer-mcp - **Impact:** Unconsented persistent control of Claude Code tool-routing context plus modification of other AI-client MCP configurations and workspace trust. - **Evidence paths:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, hooks-core/wire.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-10T07:14:43.021Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall-launched cross-client AI-agent hook and MCP configuration mutation - **Attack narrative:** On a global install outside CI, the postinstall script executes a platform installer without an explicit setup command. That installer copies executable hooks into the user profile, adds SessionStart/PreToolUse/PreCompact commands to Claude Code settings, accepts workspace trust, and configures MCP entries for several unrelated AI clients. The installed PreToolUse hook then processes future agent tool calls. This is unconsented install-time mutation of broad AI-agent control surfaces. - **Rationale:** The lifecycle hook creates persistent, cross-client agent-control changes during installation, meeting the blocking policy. No network exfiltration is needed for this concrete control-surface attack. - **Files touched:** package.json, scripts/postinstall.cjs, install-hooks.sh, install-hooks.ps1, scripts/wire-hooks.mjs, hooks-core/wire.mjs, plugin/hooks/session-start.mjs, plugin/hooks/pretooluse-router.mjs, ~/.claude-global/hooks/token-optimizer/\*\*, ~/.claude/settings.json, ~/.claude.json, ~/.cursor/mcp.json, ~/.config/Claude/claude\_desktop\_config.json, ~/.config/Code/User/globalStorage/saoudrizwan.claude-dev/cline\_mcp\_settings.json, ~/.config/Windsurf/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 runs postinstall automatically., scripts/postinstall.cjs invokes install-hooks.sh/.ps1 on global installs., install-hooks.sh copies hooks to ~/.claude-global/hooks/token-optimizer and rewrites ~/.claude/settings.json., hooks-core/wire.mjs installs SessionStart, PreToolUse, and PreCompact command hooks., install-hooks.sh also configures Claude Desktop, Cursor, Cline, Copilot, and Windsurf MCP configs., install-hooks.sh sets .claude.json workspace trust before its dry-run guard. - **Evidence against:** No credential-exfiltration or remote-payload execution path was confirmed., dist/server/daemon.js uses only local IPC and a local child server. ## Public findings ### 1.
