Dejared

Overview

Dejared is a Java decompiler MCP server that lets you explore, search, and decompile JAR, WAR, EAR, and AAR bytecode files. By exposing decompilation as MCP tools, it enables AI assistants like Claude to work directly with compiled Java code without manual copying between applications.

The server runs locally on your machine via the npm package dejared-mcp, speaking MCP over stdio. Installation is simple with npx -y dejared-mcp, requires no authentication, and works immediately out of the box. The latest release is v1.2.1, licensed under MIT, with source code available at hqkh4nh/dejared-mcp on GitHub.

Dejared belongs in the Development category on mcp.site and works with all major MCP clients including Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, and Zed. If you maintain Dejared, claim this listing to earn the Verified badge and ensure the information stays current.
