Gradle Class Finder MCP
Find and decompile classes within Gradle dependencies.
Gradle Class Finder MCP
一个基于 Model Context Protocol (MCP) 的 Gradle 项目类查找服务,帮助在 Gradle 项目依赖中查找指定的类并获取其源代码。
功能特性
- 在 Gradle 项目依赖中查找指定的类
- 获取类的源代码或反编译代码
- 支持 JDK 类查找
- 智能类名解析(支持简单类名)
- Kotlin 类智能识别和反编译
运行方式
方式一:Java 原生运行
前置要求
- JDK 17 或更高版本
- Gradle 8.5 或更高版本(可选,项目包含 Gradle Wrapper)
构建项目
# 使用 Gradle Wrapper(推荐)
./gradlew shadowJar
# 或者使用系统安装的 Gradle
gradle shadowJar
构建完成后,会在 build/libs/ 目录下生成 gradle-class-finder-mcp.jar 文件。
运行服务
# 直接运行 JAR 文件
java -jar build/libs/gradle-class-finder-mcp.jar
# 或者使用 Gradle 运行
./gradlew run
方式二:Docker 运行
前置要求
- Docker 20.10 或更高版本
构建 Docker 镜像
docker build -t gradle-class-finder-mcp .
运行容器
# 基本运行
docker run gradle-class-finder-mcp
# 使用自定义内存设置
docker run -e JAVA_OPTS="-Xmx1g -Xms512m" gradle-class-finder-mcp
# 挂载本地项目目录(用于分析本地项目)
docker run -v /path/to/your/project:/workspace gradle-class-finder-mcp
配置 Claude Desktop
在 Claude Desktop 的配置文件中添加以下配置:
Java 原生运行配置
{
"mcpServers": {
"gradle-class-finder": {
"command": "java",
"args": ["-jar", "/path/to/gradle-class-finder-mcp.jar"]
}
}
}
Docker 运行配置
{
"mcpServers": {
"gradle-class-finder": {
"command": "docker",
"args": ["run", "-i", "gradle-class-finder-mcp"]
}
}
}
使用示例
查找类
使用工具 find_class 查找类:
- workspace_dir: /path/to/gradle/project
- class_name: com.example.MyClass
获取源代码
使用工具 get_source_code 获取源代码:
- jar_path: /path/to/library.jar
- class_name: com.example.MyClass
环境变量
JAVA_OPTS: JVM 参数设置(例如:-Xmx512m -Xms256m)
故障排除
Java 原生运行常见问题
-
找不到主类
- 确保使用
shadowJar任务构建,而不是普通的jar任务 - 检查 JAR 文件是否存在于
build/libs/目录
- 确保使用
-
依赖解析失败
- 确保目标项目有有效的 Gradle 配置
- 检查网络连接,确保能访问 Maven 仓库
Docker 运行常见问题
-
构建失败
- 确保 Docker 守护进程正在运行
- 检查是否有足够的磁盘空间
-
容器无法访问本地文件
- 使用
-v参数正确挂载本地目录 - 检查文件权限
- 使用

ucn
Universal Code Navigator - a lightweight MCP server that gives AI agents call-graph-level understanding of code. Instead of reading entire files, agents ask structural questions like: "who calls this function", "what breaks if I change it", "what's unused", and get precise, AST-verified answers. UCN parses JS/TS, Python, Go, Rust, Java, and HTML inline scripts with tree-sitter, then exposes 28 navigation commands as a CLI tool, MCP server, or agent skill.
uMCP (ultraMCP)
A lightweight Java framework for building MCP servers with TCP transport via mcp-java-bridge.
