What is MCP Server using Spring Boot Java?
A Model Context Protocol (MCP) server built with Spring Boot and Java 21, exposing user management tools for AI assistants. It integrates with the DummyJSON external API to provide CRUD operations on user data.
How to use MCP Server using Spring Boot Java?
Build the project with mvn clean package, then run the jar with java -jar target/mcp-spring-java-0.0.1-SNAPSHOT.jar. The server supports both STDIO and SSE transports; configure it in application.yml (default port 8090) or via command-line flags. Test tools by sending POST requests to /mcp/message with a JSON payload specifying the tool name and parameters. For use with MCP clients, add a configuration entry pointing to the jar with -Dspring.ai.mcp.server.stdio=true.

常见问题
How can I test the server without an MCP client?
Use Postman to send a POST request to `http://localhost:8090/mcp/message` with a JSON body containing the tool call. Example: `{"message":{"toolCalls":[{"id":"call-123","name":"getUserById","parameters":{"id":1}}]}}`.
What are the runtime dependencies?
Java 21 or higher and Maven are required to build and run the application. The project uses Lombok, Spring AI, and the DummyJSON API (external).
Which transports does it support?
Standard I/O (STDIO) for terminal‑based communication and Server‑Sent Events (SSE) via the `/mcp/message` endpoint.
Where does the user data come from?
All user data is fetched from the DummyJSON external API; no local database is used.
