The BrowserStack MCP Server allows you to manage test cases, execute tests, debug issues, and fix code directly within tools like Cursor, Claude, or any MCP-enabled client using natural language. This server connects BrowserStack's comprehensive test platform to your favorite AI tools, reducing context switching and enabling testing through plain English prompts.
Create a .vscode/mcp.json file with the following content:
{
"servers": {
"browserstack": {
"command": "npx",
"args": ["-y", "@browserstack/mcp-server@latest"],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}
In VSCode, click the "Start" button in the MCP Server to start the server.
Create a .cursor/mcp.json file with the following content:
{
"mcpServers": {
"browserstack": {
"command": "npx",
"args": ["-y", "@browserstack/mcp-server@latest"],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}
Create a ~/claude_desktop_config.json file with the following content:
{
"mcpServers": {
"browserstack": {
"command": "npx",
"args": ["-y", "@browserstack/mcp-server@latest"],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}
Click the "MCP Servers" icon in the navigation bar, select the "Installed" tab, and click the "Configure MCP Servers" button. Then use the following configuration:
{
"mcpServers": {
"browserstack": {
"command": "npx",
"args": ["-y", "@browserstack/mcp-server@latest"],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}
For an automated installation with Claude Desktop:
npx -y @smithery/cli install @browserstack/mcp-server --client claude

To add this MCP server to Claude Code, run this command in your terminal:
claude mcp add-json "browserstack" '{"command":"npx","args":["-y","@browserstack/mcp-server@latest"],"env":{"BROWSERSTACK_USERNAME":"<username>","BROWSERSTACK_ACCESS_KEY":"<access_key>"}}'See the official Claude Code MCP documentation for more details.
There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.
If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.
To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".
When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:
{
"mcpServers": {
"browserstack": {
"command": "npx",
"args": [
"-y",
"@browserstack/mcp-server@latest"
],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.
Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.
The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.
You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.
To add this MCP server to Claude Desktop:

~/Library/Application Support/Claude/claude_desktop_config.json%APPDATA%\Claude\claude_desktop_config.json~/.config/Claude/claude_desktop_config.json2. Add this to your configuration file:
{
"mcpServers": {
"browserstack": {
"command": "npx",
"args": [
"-y",
"@browserstack/mcp-server@latest"
],
"env": {
"BROWSERSTACK_USERNAME": "<username>",
"BROWSERSTACK_ACCESS_KEY": "<access_key>"
}
}
}
}3. Restart Claude Desktop for the changes to take effect
