01 · Install SeleniumBase MCP

Claude Code

claude mcp add seleniumbase-seleniumbase -- uvx seleniumbase

Claude Desktop / Cursor / VS Code - add to config

  "mcpServers": {
    "seleniumbase-seleniumbase": {
      "command": "uvx",
      "args": [
        "seleniumbase"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
