BrowserStack MCP Server

Manage test cases, execute manual or automated tests, debug issues, and even fix code—directly within tools like Cursor, Claude, or any MCP-enabled client, using plain English.

Test from anywhere:

Easily connect the BrowserStack Test Platform to your favourite AI tools, such as IDEs, LLMs, or agentic workflows.

Reduced context switching:

Stay in flow—keep all project context in one place and trigger actions directly from your IDE or LLM.

💡 Usage Examples

📱 Manual App Testing

Test mobile apps on real devices across the latest OS versions. Reproduce bugs and debug crashes without setup hassles. Below are some sample prompts to use your mobile apps on BrowserStack's extensive cloud of real devices

# 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, you can debug crashes and performance issues in real-time.
• Access all major devices and OS versions from our device grid, We have strict SLAs to provision our global datacenters with newly released devices on launch day.

🌐 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!

# Test your websites
"open my website hosted on localhost:3001 on Edge"
"open browserstack.com on latest version of Chrome"

• Test websites across different browsers and devices. We support every major browser 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..)

Auto-analyze, diagnose, and even fix broken test scripts right in your IDE or LLM. Instantly fetch logs, identify root causes, and apply context-aware fixes. No more debugging loops. Below are few example prompts to run/debug/fix your automated tests on BrowserStack's Test Platform.

#Port test suite to BrowserStack
"Setup test suite to run on BrowserStack infra"

#Run tests on BrowserStack
“Run my tests on BrowserStack”

#AI powered debugging of test failures
"My App Automate tests have failed, can you help me fix the new failures?"

• Fix test failures reported by your CI/CD pipeline by utilising our industry leading Test Observability features. Find more info here.
• Run tests written in Jest, Playwright, Selenium, and more on BrowserStack's Test Platform

🌐 Accessibility

Catch accessibility issues early with automated, local a11y scans. Get one-click, AI-suggested fixes. No docs hunting, no CI surprises. Ensure WCAG and ADA compliance with our Accessibility Testing tool

#Scan accessibility issues while development
"Scan & help fix accessibility issues for my website running locally on localhost:3000"

#Scan accessibility issues on production site
“Run accessibility scan & identify issues on my website - www.bstackdemo.com”

📋 Test Management

Create and manage test cases, create test plans and trigger test runs using natural language. Below are a few example prompts to utilise capabilities of BrowserStack's Test Management with MCP server.

# Create project & folder structure
"create new Test management project named My Demo Project with two sub folders - Login & Checkout"

# Add test cases
"add invalid login test case in Test Management project named My Demo Project"

# List added test cases 
"list high priority Login test cases from Test Management project - My Demo Project"

# Create test run
"create a test run for Login tests from Test Management project - My Demo Project"

# Update test results
"update test results as passed for Login tests test run from My Demo Project"

🧪 Access BrowserStack AI agnets

Generate test cases from PRDs, convert manual tests to low-code automation, and auto-heal flaky scripts powered by BrowserStack’s AI agents, seamlessly integrated into your workflow. Below are few example prompts to access Browserstack AI agents

#Test case generator agent
"With Browserstack AI, create relevant test cases for my PRD located at /usr/file/location"


#Low code authoring agent
“With Browserstack AI, automate my manual test case X, added in Test Management”


#Self healing agent
“Help fix flaky tests in my test script with Browserstack AI self healing”

🤝 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. If you have any suggestions or feedback, please open an issue to discuss.
