Claude Desktop Playwright browser_tab_list

Add Playwright to Claude Desktop

1. 01

   Open ~/Library/Application Support/Claude/claude_desktop_config.json and merge this in. Keep any servers already there.

{
  "mcpServers": {
    "playwright-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@playwright/mcp"
      ]
    }
  }
}

2. 02

   Save the file and restart Claude Desktop.

3. 03

   Ask for something browser_tab_list does. Claude Desktop lists the server's tools on connect and calls browser_tab_list itself — you do not invoke it by name.

4. 04

   If nothing happens, check the server is running and that Playwright's identifier in your config matches the one above exactly.

Settings → Developer → Edit Config opens this file. Restart the app after saving. Claude Desktop docs
