MCP server for Deepin desktop application automated testing via AT-SPI
Project description
Deepin MCP
MCP (Model Context Protocol) 服务器,用于通过 AT-SPI 对 Deepin 桌面应用进行自动化测试。
Features
- AT-SPI 应用检测 — 自动发现运行中的桌面应用及其控件树
- UI 控件操作 — 通过 AT-SPI 对按钮、输入框、菜单等控件执行点击、输入等操作
- 菜单 Comb 操作 — 支持 DTK 主菜单和右键菜单的 hover-crawl 操作
- D-Bus 调用 — 直接通过 D-Bus 接口与应用交互
- 编排式测试 — 支持 YAML/JSON 格式的测试用例定义和执行
- 截图诊断 — 操作过程中自动截图辅助调试
Architecture
三层隔离架构:
| 层级 | 组件 | 职责 |
|---|---|---|
| 检测层 | TreeWalker, MenuScanner, Monitor, Snapshot | 只读的控件发现与状态监控 |
| 执行层 | ElementActor, InputController, MenuOperator, DBusExecutor | 精准的控件操作执行 |
| 编排层 | Parser, Runner, Assertions | 测试用例解析与执行编排 |
Prerequisites
- Python >= 3.10
- 桌面 Linux 环境(Deepin / UOS),依赖 AT-SPI 和 xdotool
系统依赖(必须先安装)
PyGObject 需要系统级头文件和 GIR 数据才能编译:
sudo apt install libgirepository1.0-dev gcc libcairo2-dev pkg-config python3-dev gir1.2-atspi-2.0
安装 uv(推荐)
# macOS / Linux
curl -LsSf https://astral.sh/uv/install.sh | sh
# 或使用 pip
pip install uv
Installation
# 使用 uv 安装(推荐)
uv tool install deepin-mcp
# 或使用 pip
pip install deepin-mcp
Usage
作为 MCP 服务器运行(stdio 模式,默认)
deepin-mcp
作为 MCP 服务器运行(HTTP 模式)
DEEPIN_MCP_TRANSPORT=http deepin-mcp
远程访问时可指定监听地址和端口:
DEEPIN_MCP_TRANSPORT=http DEEPIN_MCP_HOST=0.0.0.0 DEEPIN_MCP_PORT=8000 deepin-mcp
| 环境变量 | 默认值 | 说明 |
|---|---|---|
DEEPIN_MCP_TRANSPORT |
stdio |
传输模式,可选 stdio 或 http |
DEEPIN_MCP_HOST |
127.0.0.1 |
HTTP 模式监听地址,远程访问设为 0.0.0.0 |
DEEPIN_MCP_PORT |
8000 |
HTTP 模式监听端口 |
运行测试用例
# test_case.yaml
name: "Calculator addition"
app: "deepin-calculator"
steps:
- name: "Click 5"
action: element_action
selector: {name: "5"}
- name: "Click +"
action: element_action
selector: {name: "+"}
- name: "Click 3"
action: element_action
selector: {name: "3"}
- name: "Click ="
action: element_action
selector: {name: "="}
- name: "Verify result"
assert:
- type: element_text
selector: {role: "text"}
contains: "8"
