About Promptium
Promptium is a Java and Appium-based UI automation framework for developers testing mobile apps with natural-language instructions. It uses LLMs to interpret actions and includes an MCP server for Claude Desktop.
Key features
- 01Appium-based device and UI automation
- 02Simulator and physical-device support
- 03LLM interpretation of natural-language test instructions
- 04MCP server connection for Claude Desktop
Use cases
- 01Run mobile tests from natural-language instructions
- 02Capture screens, tap, and swipe on simulators or devices
MCP support
Promptium implements an MCP server that connects with Claude Desktop and supports language-driven test flows.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

LLM-Driven UI Automation with Appium and MCP
This project is a Java-based UI automation framework that integrates with Appium and utilizes LLMs (like Claude) to drive intelligent test actions on mobile devices and simulators.
Key Features
-
UI Automation with Appium
Supports device interaction such as tap, swipe/scroll, and screenshot capture on both local simulators and real/physical devices. -
LLM Integration for Intelligent Test Control
Leverages large language models (LLMs) to interpret natural-language instructions and drive UI behavior. -
Model Context Protocol (MCP) Server
Implements an MCP server to allow communication with Claude Desktop, enabling context-aware, language-driven test flows. -
Java-Based Architecture
Built with Java for reliability, performance, and seamless integration with existing test ecosystems.
Technologies Used
- Java 23+ (Minimum Required Java 17)
- Appium
- MCP Protocol
- LLM (Claude Desktop integration)

Configration Steps (for macOS)
- Install Homebrew
- Install:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)" - Add to System Path:
echo 'eval "$(/opt/homebrew/bin/brew shellenv)"' >> ~/.zprofile eval "$(/opt/homebrew/bin/brew shellenv)"
- Install:
- Install Node:
brew install node - Install Appium
npm install -g appium - Install XCode:
xcode-select --install - Carthage
brew install carthage(Only for Physical iOS Devices) - Install XCUITest Plugin for appium
appium driver install xcuitest
iOS Device Access Requirements
- Apple Hardware Required
- You must have Xcode installed from the App Store on Mac.
- Connect a real iOS device via USB or use a simulator.
- Trust the developer certs on the device (if testing on real devices).
- Enable Developer Mode on ios in System Settings > Privacy & Security > Developer Mode > On
- Enable UI Automation on ios in System Settings > Developer > Enable UI Automation (Tap/Toggle to enable)
Claude Setup
- Download Claude Desktop from https://claude.ai/download (Mcp not supported on claude web yet.)
- Setup MCP -> Settings > Developer > Edit Config
- Add the following code to
claude_desktop_config.jsonundermcpServers, if you want to use the offical release.{ "promptium": { "command": "sh", "args": ["-c", "curl -sL https://github.com/sycophant21/promptium/releases/latest/download/Promptium_v0.0.1.jar -o /tmp/promptium-mcp-server.jar && java -jar /tmp/promptium-mcp-server.jar"] } } - Add the following code to
claude_desktop_config.jsonundermcpServers, if you want to use your own compiled version.
Note: Jar can be compiled using java and maven, the instructions to create the jar are already written in the pom.xml file, just run{ "promptium": { "command": "java", "args": ["-jar", "Absolute-Path/to/your/compiled/jar"] } }mvn packagein the project folder and you will find the jar inside "/target" folder. Use the shaded jar.

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
