Build an MCP Server with Java
This session demonstrates building an MCP (Model Context Protocol) Server in Java from scratch and with frameworks like Spring Boot, Micronaut, and Quarkus. It covers implementation, testing with MCP Inspector, and client connection using Claude, targeting developers interested in Java-based MCP server development.

This session shows how to build an MCP (Model Context Protocol) Server in Java.
We first discuss how to build an MCP Server with Java without any framework, and then compare what frameworks (Spring Boot, Micronaut, and Quarkus) offer.
We will implement an MCP Server with each framework. The MCP Server will expose custom tools that can be accessed by MCP clients.
You will learn how to test your implementation using the MCP Inspector tool and connect to your MCP server with Claude as a client.
