Spring Boot Sample MCP Server

What is Spring Boot Sample MCP Server?

Spring Boot Sample MCP Server is a sample implementation of a Model Context Protocol (MCP) server using Spring Boot. It is designed for testing and debugging with the MCP Inspector and provides a simple REST API. It targets developers who want to learn or prototype MCP integration with Spring Boot.

How to use Spring Boot Sample MCP Server?

Build the server with mvn clean package, then run the jar with arguments --port 8080 --host localhost. To test, install the MCP Inspector globally via npm and run it with the appropriate command, including the built jar and an optional JAVA_TOOL_OPTIONS environment variable for remote debugging. For production use with AI assistants, configure the server in the assistant’s MCP settings using the provided JSON snippet.

FAQ from Spring Boot Sample MCP Server

What is the Model Context Protocol (MCP)?

MCP is an open standard that defines how AI models communicate with external tools and data sources, creating a standardized way for assistants like Claude to access real-time information, databases, APIs, and file systems.

What are the runtime requirements for this server?

Java 17+ and Maven are required. The MCP Inspector (optional for testing) requires Node.js/npm.

How do I configure this server for Claude Desktop?

Add the provided JSON snippet to your Claude Desktop configuration, specifying the java command, the jar path, and desired port/host. An optional JAVA_TOOL_OPTIONS environment variable enables remote debugging.

How can I test the server during development?

Build the project with Maven, then run the MCP Inspector via npx @modelcontextprotocol/inspector with the server command and any desired debugging options. The inspector provides a browser interface to send requests and view responses.

Does this server use Spring AI?

The README references Spring AI’s extensions for building MCP servers with Spring Boot, but the sample itself is primarily a Spring Boot MCP server with a focus on the MCP Java SDK.
