## Description

This MCP server provides Java class file analysis and decompilation capabilities, integrating with Maven repositories and Java decompilation tools to enable deep inspection of compiled Java bytecode. Built by handsomestWei with TypeScript and featuring CFR decompiler integration, dependency scanning, and Maven repository support, it offers tools for analyzing class file structure, decompiling bytecode to readable Java source, scanning JAR dependencies, and extracting metadata from compiled artifacts. The implementation includes environment configuration for Java and Maven paths, automatic class indexing with caching, and archive handling for JAR/ZIP files, making it valuable for reverse engineering Java applications, dependency analysis, security auditing, and understanding third-party library implementations where source code is unavailable.
