Frequently Asked Questions (FAQ) about Limetest MCP Server

Q: What is Limetest MCP Server?

A: Limetest MCP Server is an AI-powered end-to-end testing framework designed to streamline and enhance the software testing process. It allows developers to define test cases in natural language, which AI then executes automatically.

Q: How does Limetest MCP Server differ from traditional testing frameworks?

A: Unlike traditional frameworks that require complex scripting, Limetest utilizes AI to interpret and execute test cases written in plain language. It also leverages Playwright snapshot for faster and more reliable execution, and includes vision capabilities for handling complex test scenarios.

Q: What is Playwright snapshot and how does Limetest use it?

A: Playwright snapshot is a feature that captures the state of an application at a specific point in time. Limetest uses Playwright snapshot instead of pixel analysis for faster and more accurate execution of test cases.

Q: What are the vision capabilities of Limetest MCP Server?

A: Limetest can seamlessly fall back to vision mode when snapshot mode encounters limitations, such as dynamic content or complex visual elements. This ensures comprehensive testing coverage in sophisticated test scenarios.

Q: What is an MCP Server?

A: MCP (Model Context Protocol) server acts as a bridge, allowing AI models to access and interact with external data sources and tools.

Q: What are some use cases for Limetest MCP Server?

A: Limetest MCP Server can be used for automated testing planned and executed by LLMs, end-to-end testing of AI agents, continuous integration and continuous delivery (CI/CD), regression testing, and cross-browser testing.

Q: How does Limetest MCP Server integrate with UBOS?

A: Limetest MCP Server integrates with the UBOS platform to create a comprehensive AI agent development ecosystem. UBOS provides capabilities such as AI agent orchestration, enterprise data connectivity, custom AI agent development, and multi-agent systems.

Q: What is UBOS?

A: UBOS is a full-stack AI Agent Development Platform designed to empower businesses with the tools and infrastructure they need to build, orchestrate, and deploy AI agents at scale.

Q: How do I install Limetest?

A: You can install Limetest using npm with the following commands:

bash npm install @limetest/limetest npx playwright install

Q: How do I run tests with Limetest?

A: You can run tests with Limetest using the following command:

bash npx limetest example

Use the --headless flag for running tests headlessly in CI workflows.

Q: How do I configure the Limetest MCP Server?

A: To configure the Limetest MCP Server, you need to install the MCP package and configure your MCP client as follows:

bash npm install @limetest/mcp npx playwright install

Then, add the following configuration to your MCP client:

{ “mcpServers”: { “limetest”: { “command”: “npx”, “args”: [ “npx @limetest/mcp”, “–api-key=” ] } }

Note: You need an OpenAI API key to run the MCP server in end-to-end mode.

Q: Where is user data stored by Limetest?

A: Limetest launches Chrome browser with a new profile. The location depends on your OS:

• Windows: %USERPROFILE%AppDataLocalms-limetestmcp-chrome-profile
• macOS: ~/Library/Caches/ms-limetest/mcp-chrome-profile
• Linux: ~/.cache/ms-limetest/mcp-chrome-profile

Q: Is Limetest open source?

A: Limetest is based on Microsoft’s Playwright MCP and distributed under the Apache 2.0 License.
