3. Install the MCP Server

   • VSCode (Copilot - Agent Mode): .vscode/mcp.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.
