MCP Elicitations in Spring AI: Request Missing Information from Users

What happens when your MCP tool gets called but the user didn't provide all the required information? Before elicitations, it would simply fail. Now there's a better way.

In this tutorial, you'll learn how to implement MCP Elicitations in Spring AI, a standardized approach for servers to request additional information from users during an interaction. We'll build a complete coffee shop ordering system where the MCP server dynamically asks for missing details like coffee size, type, and milk preference.

🎯 What You'll Learn:
• Understanding elicitations in the MCP specification (form mode vs URL mode)
• Building an MCP server with elicitation support using Spring Boot
• Creating tool parameters with the @MCPTool and @MCPToolParams annotations
• Testing elicitations in the MCP Inspector
• Building a Spring AI client with the @MCPElicitation annotation
• Handling elicitation requests and responses in a real application
