Java Decompiler FAQs

Question 1

What is the Java Decompiler?

Accepted Answer

It's a tool that converts compiled Java class files back into readable Java source code. It uses a Model Context Protocol (MCP) server to decompile, making it easy to integrate with AI assistants and other tools.

Question 2

What file types does it support?

Accepted Answer

It can decompile .class files directly, classes specified by package name, and classes contained within JAR files.

Question 3

Do I need Java installed to use this?

Accepted Answer

No, this decompiler uses a JavaScript port of the CFR decompiler, so you don't need a Java Runtime Environment (JRE) installed on your system.

Question 4

How do I use it with an MCP client?

Accepted Answer

You can configure your MCP client to use this server by specifying the command to run it. See the documentation for an example configuration.

Question 5

What if I have issues decompiling a specific class file?

Accepted Answer

Try using the `decompile-from-package` tool with an explicit classpath or the `decompile-from-jar` tool specifying the class name. Ensure the class file is valid and not corrupt.
