# BrowserStack MCP Server

One Platform For All Your Testing Needs

Enable every developer and tester in your team, whether they are testing manually, starting their automation journey, or scaling test automation. BrowserStack MCP Server allows you to use our cutting-edge [Test Platform](https://www.browserstack.com/test-platform) directly from your favourite AI tools. ### Why BrowserStack ?

overview

## 💡 Usage Examples ### 📱 Manual App Testing Use the following prompts to use your **mobile apps** on BrowserStack's extensive cloud of real devices. Stop using emulators! ```bash # Open app on specific device "open my app on a iPhone 15 Pro Max" # Debug app crashes "My app crashed on Android 14 device, can you help me debug?" ``` - Unlike emulators, test your app's real-world performance on actual devices. With advanced [App-Profiling features](https://www.browserstack.com/docs/app-live/app-performance-testing), you can debug crashes and performance issues in real-time. - Access all major devices and OS versions from our [device grid](https://www.browserstack.com/list-of-browsers-and-platforms/app_live), We have strict SLAs to provision our global datacenters with newly released devices on [launch day](https://www.browserstack.com/blog/browserstack-launches-iphone-15-on-day-0-behind-the-scenes/). ### 🌐 Manual Web Testing Similar to the app testing, you can use the following prompts to test your **websites** on BrowserStack's extensive cloud of real browsers and devices. Don't have Edge browser installed on your machine ? We've got you covered! ```bash # Test your local websites "open my website hosted on localhost:3001 on Edge" ``` - Test websites across different browsers and devices. We support [every major browser](https://www.browserstack.com/list-of-browsers-and-platforms/live) across every major OS. - Seamlessly test websites hosted locally on your machine, no need to deploy to a remote server! ### 🧪 Automated Testing (Playwright, Selenium, A11y and more..) Use the following prompts to run/debug/fix your **automated tests** on BrowserStack's [Test Platform](https://www.browserstack.com/test-platform). ```bash # Port test suite to BrowserStack "run my test suite on BrowserStack infra" # Debug test failures "My test suite failed, can you help me fix the new failures?" # Accessibility testing "check for accessibility issues on my www.mywebsite.com" ``` - Fix test failures reported by your CI/CD pipeline by utilising our industry leading [Test Observability](https://www.browserstack.com/docs/test-observability) features. Find more info [here](https://www.browserstack.com/docs/test-observability/features/smart-tags). - Run tests written in Jest, Playwright, Selenium, and more on BrowserStack's [Test Platform](https://www.browserstack.com/test-platform) - **Accessibility Testing**: Ensure WCAG and ADA compliance with our [Accessibility Testing](https://www.browserstack.com/accessibility-testing) tool ## 🛠️ Installation 1. **Create a BrowserStack Account** - Sign up for [BrowserStack](https://www.browserstack.com/users/sign_up) if you don't have an account already. - ℹ️ If you have an open-source project, we'll be able to provide you with a [free plan](https://www.browserstack.com/open-source).

- Once you have an account (and purchased appropriate plan), note down your `username` and `access_key` from [Account Settings](https://www.browserstack.com/accounts/profile/details). 2. Ensure you are using Node version >= `18.0`. Check your node version using `node --version`. Recommended version: `v22.15.0` (LTS) 3. **Install the MCP Server** - VSCode (Copilot - Agent Mode): `.vscode/mcp.json`: ```json { "servers": { "browserstack": { "command": "npx", "args": ["-y", "@browserstack/mcp-server@latest"], "env": { "BROWSERSTACK_USERNAME": "", "BROWSERSTACK_ACCESS_KEY": "" } } } } ``` - In VSCode, make sure to click on `Start` button in the MCP Server to start the server. ![Start MCP Server](assets/vscode_install.png) * For Cursor: `.cursor/mcp.json`: ```json { "mcpServers": { "browserstack": { "command": "npx", "args": ["-y", "@browserstack/mcp-server@latest"], "env": { "BROWSERSTACK_USERNAME": "", "BROWSERSTACK_ACCESS_KEY": "" } } } } ``` - Claude Desktop: `~/claude_desktop_config.json`: ```json { "mcpServers": { "browserstack": { "command": "npx", "args": ["-y", "@browserstack/mcp-server@latest"], "env": { "BROWSERSTACK_USERNAME": "", "BROWSERSTACK_ACCESS_KEY": "" } } } } ``` ### Installing via Smithery To install BrowserStack Test Platform Server for Claude Desktop automatically via [Smithery](https://smithery.ai/server/@browserstack/mcp-server): ```bash npx -y @smithery/cli install @browserstack/mcp-server --client claude ``` ## 🤝 Recommended MCP Clients - We recommend using **Github Copilot or Cursor** for automated testing + debugging use cases. - For manual testing use cases (Live Testing), we recommend using **Claude Desktop**. ## ⚠️ Important Notes - The BrowserStack MCP Server is under active development and currently supports a subset of the MCP spec. More features will be added soon. - Tool invocations rely on the MCP Client which in turn relies on an LLM, hence there can be some non-deterministic behaviour that can lead to unexpected results.
