Custom MCP Server

Example Use Cases

• 1

  Learn and experiment with MCP server implementation in Java.

• 2

  A reference MCP server supporting JSON-RPC 2.0 and stdio transport.

• 3

  A base to extend MCP server functionality with custom tools.

Description

This project is a learning tool to understand the fundamentals of the Model Context Protocol (MCP) by implementing a server in Java. It supports JSON-RPC 2.0 communication over stdio transport, tool listing and execution, and an initialize handshake for capability negotiation. The server follows the ECB pattern for clean architecture and currently includes an echo tool example. It is designed to help developers grasp how MCP servers function and interact with clients.
