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 📚 Resources: GitHub Repository: https://github.com/danvega/spring-ai-mcp-elicitation MCP Elicitations Docs: https://modelcontextprotocol.io/docs/concepts/elicitation Spring AI Reference: https://docs.spring.io/spring-ai/reference/ Spring Initializr: https://start.spring.io 👋🏻Connect with me: Website: https://www.danvega.dev Twitter: https://twitter.com/therealdanvega Github: https://github.com/danvega LinkedIn: https://www.linkedin.com/in/danvega Newsletter: https://www.danvega.dev/newsletter SUBSCRIBE TO MY CHANNEL: http://bit.ly/2re4GH0 ❤️
