• Continuous Watch: mcptoon sync --watch monitors config files for real-time sync
• Health Check: mcptoon health detects zombie/dead MCP servers
• Built-in Serve Bridge: mcptoon serve acts as a unified MCP server for all your tools
• Token Dashboard: mcptoon stats shows token savings per server
• Per-Tool Toggle: mcptoon toggle enables/disables individual tools
