## Description

ReModern Java is an MCP server implementation built by Phodal that provides a comprehensive toolkit for Java legacy modernization and development tasks. The server exposes six specialized tools through both CLI and MCP interfaces: AST-based code generation using JavaPoet, template-driven code generation with FreeMarker, Java source code parsing and analysis via JavaParser, JSP file parsing and analysis, bytecode analysis using ASM, and OpenRewrite integration for AST migration and refactoring. Built on the official MCP Java SDK 0.10.0, it's designed for modernizing legacy Java applications, automating code generation workflows, and performing deep code analysis across Java codebases, making it particularly valuable for enterprise Java migration projects and AI-assisted development workflows.
