What is MCP Java Decompiler Server
MCP Java Decompiler Server is an open-source tool developed by Ivan Dachev that acts as a Model Context Protocol (MCP) server for decompiling Java class files. It is designed to allow AI assistants and other tools that implement the MCP protocol to convert Java bytecode (.class files) back into readable Java source code. The server can process class files from direct file paths, Java packages, or JAR archives, making it versatile for developers, automation tools, and AI agents that need to analyze Java codebases. It operates without requiring a local Java installation by utilizing a JavaScript port of the CFR decompiler, and offers a simple, MCP-compatible API for seamless integration with AI and developer workflows.
