BrowserStack MCP Server brings the power of BrowserStack's Test Platform directly into your development workflow. It enables you to run tests, debug applications, and perform cross-browser testing through any MCP-compliant client.

• Real Device Testing: Test your mobile apps on BrowserStack's extensive cloud of real devices
• Performance Testing: Unlike emulators, test your app's real-world performance on actual devices
• Live Debugging: Debug crashes and performance issues in real-time
• Comprehensive Device Coverage: Access all major devices and OS versions from our device grid

• Local Testing: Seamlessly test websites hosted on localhost
• Cross-Browser Testing: Test websites across different browsers and devices
• Screenshot Testing: Capture and compare screenshots across different environments

• Fix Test Failures: Leverage AI to identify and fix test failures reported by your CI/CD pipeline by utilising our industry leading Test Observability features. Find more info here.
• Run on BrowserStack: Easily run tests written in Jest, Playwright, Selenium, and more on BrowserStack's Test Platform
• Accessibility Testing: Ensure WCAG and ADA compliance with our Accessibility Testing tool

   • For Github Copilot users, ensure you are using the latest version of the VSCode with support for Copilot agent mode.

# 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?"

# Test local website
"open my website hosted on localhost:3001 on a Windows Edge browser and take a screenshot"

# Check website compatibility
"open test.com on Samsung Browser and check for readability issues"

# Run test suite
"run my test suite on BrowserStack"

# 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"

• Github Copilot or Cursor (Recommended for automated testing + debugging)
• Claude Desktop (Recommended for manual testing)

• The BrowserStack MCP Server is under active development and currently supports a subset of the MCP protocol, i.e. tools. More features will be added soon.
• As tool invocation relies on the MCP Client which in turn rely on LLMs for tool calling. There can be some non-deterministic behaviour and can lead to unexpected results. If you have any suggestions or feedback, please open an issue to discuss.
