Dejared MCP Server

dejared-mcp is a Java decompiler and JAR analyzer that speaks the Model Context Protocol. It lets an AI coding agent (Claude Code, Codex, Cursor, VS Code) open a .jar, .war, .ear, or .aar, list what is inside, search its bytecode, and decompile any class back to Java source using CFR, Vineflower, or Procyon. It runs locally over stdio via the published package.

People connecting browser automation tools to Claude, Cursor, VS Code, or another MCP client. The project is written in Java.
