Learn how to build an MCP Server in Java

🔍 Discover how to implement a Model Context Protocol (MCP) server using only the core Java SDK. This tutorial expands on our MCP series by showing you a more lightweight, flexible approach for projects where Spring isn't necessary.

In this video, I walk you through creating a complete MCP server implementation using standard Java. You'll learn how to set up core dependencies, implement a simple tool that provides JavaOne presentation data, configure STDIO transport, and test your implementation using the MCP Inspector tool.

What You'll Learn:
Setting up the core MCP Java dependency
Implementing an MCP server with the standard Java SDK
Working with the default STDIO transport implementation
Creating custom tools that can be accessed by MCP clients
Testing your implementation with the MCP Inspector
Connecting your MCP server to Claude as a client
