Under the System Message field, enter the following text: \"You are a helpful assistant. Current datetime is {{ $now.toString() }}\". This message provides the AI with the current date and time, which can be useful for context in various interactions.\n\nNext, select an appropriate Large Language Model (LLM) from the available options. This model will be responsible for handling the chat and delivering events.\n\nTo enable continuous and context - aware conversations, add memory to the Agent. This allows the AI Agent to remember previous interactions, providing a more seamless and engaging chat experience.\n\nFinally, search for and add the \"MCP Client\" tool. In the SSE Endpoint section of the \"MCP Client\" configuration, paste the URL that you copied in Step 4. This step connects the AI Agent workflow to the MCP Server, enabling data flow and interaction between the two. "
