Can I use this to decompile Java classes?

No, this skill is designed for exploring and reading raw file contents. For class search and decompilation, use the maven-indexer MCP server tools.

Do I need the Java Development Kit (JDK) installed?

This skill utilizes specialized scripts to read JAR contents directly and does not require the standard 'jar' or 'unzip' commands to be available.

What files can I read with JAR Explorer?

You can read any non-binary or configuration file such as .properties, .xml, .yaml, and .txt files located inside the JAR.

Is this tool safe for auto-approval in Claude Code?

Yes, JAR Explorer is a read-only tool that outputs to stdout without writing to the disk, making it safe for automated workflows.

開発者ツール

Inspects JAR file contents, searches for entries, and reads configuration files without extraction.

JAR Explorer provides a specialized set of tools for Claude Code to interact with Java Archive (JAR) files directly. It allows for listing internal directories, performing regex-based searches for specific entries, and reading non-class files like XML configs, property files, and manifests without the need to manually extract them to disk. This is particularly useful for debugging dependency configurations, verifying build outputs, and inspecting metadata in large enterprise Java projects where manual extraction is cumbersome or prone to cluttering the workspace.

主な機能

01Bypasses the need for manual extraction using unzip or jar xf commands.

02List all internal JAR entries and directory structures via a simple CLI.

030 GitHub stars

04Read raw file contents like properties and manifests directly from the JAR.

05Perform case-insensitive regex searches for specific filenames within archives.

06Safe, read-only operation optimized for Claude Code auto-approval hooks.

ユースケース

01Verifying MANIFEST.MF or spring.factories content to debug classpath and auto-configuration issues.

02Searching for specific resource files or configuration properties within deep dependency trees.

03Inspecting the contents of project build artifacts to ensure assets are correctly packaged.
