The Tools tab allows you to manage the AI tools available in your Digital Twin. This includes enabling or disabling specific tools that assist the AI in performing various tasks. Your Digital Twin uses tools to assist with specific functionality—memory, image analysis and generation, web browsing, document retrieval, LMS integration, and more. Use this page to select which tools you wish to disable (if any) for your instance. By default, all applicable tools are enabled. MCP Servers and Tools
