How to Set Up and Use Hello Spring
Hello Spring MCP Server is a Kotlin-based Spring Boot application that demonstrates how to expose a Spring service via the Model Context Protocol. It serves as a reference implementation for developers who want to integrate Spring Boot backends with MCP-compatible AI clients such as Claude, making it ideal for learning how MCP works within the JVM ecosystem.
Prerequisites
- Java 21 or higher installed (required by Spring Boot 3.x)
- Gradle build tool (the project ships with the Gradle wrapper)
- Git to clone the repository
- Claude Desktop or Claude Code for testing
Clone the repository
Clone the hello-spring-mcp-server repository from GitHub to get the full project including build scripts and source code.
git clone https://github.com/jamesward/hello-spring-mcp-server.git
cd hello-spring-mcp-serverBuild the project
Use the included Gradle wrapper to compile the Kotlin source and produce a runnable JAR. This downloads all dependencies defined in build.gradle.kts automatically.
./gradlew buildRun the MCP server locally
Start the Spring Boot application using the Gradle bootRun task. The server will start and listen for MCP connections via stdio or HTTP depending on the active Spring profile.
./gradlew bootRunConfigure Claude Desktop to use the server
Add an entry to your Claude Desktop config file pointing to the Spring Boot JAR. The server communicates over stdio so Claude can launch it as a subprocess.

Example prompts to test the Hello Spring MCP server once Claude is connected.
- "What tools does the hello-spring server expose?"
- "Call the hello tool and show me the response"
- "List all available MCP capabilities from the spring server"
- "Use the spring server to get a greeting message"Troubleshooting Hello Spring
Build fails with 'Unsupported class file major version' error
The project requires Java 21 or later. Run java -version to check your installed version. Install a compatible JDK from https://adoptium.net and set JAVA_HOME to point to it.
Claude Desktop shows the server as disconnected
Verify the JAR path in the config is absolute and correct. Run the java -jar command manually in a terminal to confirm the server starts without errors before adding it to Claude Desktop.
Gradle wrapper script not executable on macOS or Linux
Run chmod +x ./gradlew to make the wrapper executable, then retry ./gradlew build.
