Server Configuration

Describes the environment variables required to run the server.

NameRequiredDescriptionDefault
CFR_PATHNoPath to the CFR decompiler .jar file. If not provided, the server will check the project directory or attempt to download it automatically.

Instructions

Guidance the server publishes about itself, which clients place ahead of the tool catalog so the model reads it before choosing anything.

This server publishes no instructions, or was last inspected before Glama recorded them.

Tools

Functions exposed to the LLM to take actions

NameDescription
decompile_fileB
反编译单个 .class 或 .jar 文件

Args:
    file_path: 要反编译的文件路径（.class 或 .jar）
    output_dir: 输出目录，默认为文件所在目录下的 decompiled 文件夹
    save_to_file: 是否直接保存到文件系统（推荐），默认为 True。设为 False 时会返回反编译内容

Returns:
    反编译结果信息或内容
decompile_filesA
反编译多个 .class 或 .jar 文件（支持多线程）

Args:
    file_paths: 要反编译的文件路径列表
    output_dir: 输出目录，默认为当前目录下的 decompiled 文件夹
    save_to_file: 是否直接保存到文件系统（推荐），默认为 True
    show_progress: 是否显示详细进度信息，默认为 True
    max_workers: 最大并发线程数，默认为 4（设为 1 则单线程处理）

Returns:
    反编译结果信息
decompile_directoryA
反编译指定目录下的所有 .class 和 .jar 文件（支持多线程）

Args:
    directory_path: 要扫描的目录路径
    output_dir: 输出目录，默认为目标目录下的 decompiled 文件夹
    recursive: 是否递归扫描子目录，默认为 True
    save_to_file: 是否直接保存到文件系统（推荐），默认为 True
    show_progress: 是否显示详细进度信息，默认为 True
    max_workers: 最大并发线程数，默认为 4（设为 1 则单线程处理）

Returns:
    反编译结果信息
download_cfr_toolC
下载 CFR 反编译器到指定目录

Args:
    target_dir: 下载目标目录，默认为当前工作目录

Returns:
    下载结果信息
check_cfr_statusC
检查 CFR 反编译器状态

Returns:
    CFR 状态信息
get_java_versionB
获取当前系统的 Java 版本信息

Returns:
    Java 版本信息

TDQS

A3.6/5.0

Scored across 6 tools

Disambiguation3/5

The tools have clear distinctions between checking status, downloading, decompiling files/directories, and getting Java version, but decompile_file and decompile_files have overlapping purposes that could cause confusion. The directory vs. file distinction is clear, but the single vs. multiple file tools are functionally similar with minor parameter differences.

Naming Consistency5/5

All tools follow a consistent snake_case pattern with clear verb_noun structure (check_cfr_status, decompile_directory, decompile_file, decompile_files, download_cfr_tool, get_java_version). The naming is predictable and follows the same convention throughout.

Tool Count5/5

With 6 tools, this is well-scoped for a Java decompiler server. Each tool serves a distinct purpose in the decompilation workflow, from setup (download, check status) to core operations (decompile files/directories) to system information (Java version).

Completeness4/5

The toolset covers the essential decompilation workflow comprehensively: tool setup (download, status check), decompilation operations at different granularities (file, files, directory), and system verification (Java version). A minor gap is the lack of configuration tools for CFR options or cleanup operations for decompiled output.
