Implementation Reference

• index.js:367-380 (registration)

  The 'browser_tabs' tool is registered using server.tool, and it uses proxyToolCall to delegate the execution.

  server.tool('browser_tabs', 'Manage tabs', {
    action: z.enum(['list', 'new', 'close', 'select']),
    index: z.number().optional()
  }, async (args) => {
    // 'new' action can work without active page, others require it
    if (args.action !== 'new') {
      const check = requireActivePage();
      if (check) return check;
    }
    const result = await proxyToolCall('browser_tabs', args);
    // 'new' action creates a page
    if (args.action === 'new' && !result.isError) {
      hasActivePage = true;
    }
