Implementation Reference

• index.js:795-799 (handler)

  The main handler function for the 'get_network_errors' tool. It returns the stored networkErrors array as a JSON string in the MCP response format.
  async getNetworkErrors() { return { content: [{ type: 'text', text: JSON.stringify(networkErrors, null, 2) }], }; }
• index.js:373-374 (registration)

  Registration and dispatch in the CallToolRequestSchema switch statement, which calls the handler function.
  case 'get_network_errors': return await this.getNetworkErrors();
• index.js:255-262 (schema)

  Tool schema and metadata registration in the ListToolsRequestSchema response, defining the tool name, description, and empty input schema.
  { name: 'get_network_errors', description: 'Get network error logs', inputSchema: { type: 'object', properties: {}, }, },
• index.js:103-343 (registration)

  Overall tool registration block where all tools including 'get_network_errors' are listed for discovery.
  this.server.setRequestHandler(ListToolsRequestSchema, async () => ({ tools: [ { name: 'navigate', description: 'Navigate to a URL', inputSchema: { type: 'object', properties: { url: { type: 'string', description: 'The URL to navigate to', }, }, required: ['url'], }, }, { name: 'screenshot', description: 'Take a screenshot of the current page', inputSchema: { type: 'object', properties: { name: { type: 'string', description: 'Name for the screenshot file', default: 'screenshot.png', }, fullPage: { type: 'boolean', description: 'Capture full page', default: false, }, }, }, }, { name: 'click', description: 'Click an element on the page', inputSchema: { type: 'object', properties: { selector: { type: 'string', description: 'CSS selector for the element to click', }, }, required: ['selector'], }, }, { name: 'fill', description: 'Fill an input field', inputSchema: { type: 'object', properties: { selector: { type: 'string', description: 'CSS selector for the input field', }, value: { type: 'string', description: 'Value to fill', }, }, required: ['selector', 'value'], }, }, { name: 'evaluate', description: 'Execute JavaScript in the browser', inputSchema: { type: 'object', properties: { script: { type: 'string', description: 'JavaScript code to execute', }, }, required: ['script'], }, }, { name: 'get_content', description: 'Get page content (HTML or text)', inputSchema: { type: 'object', properties: { type: { type: 'string', enum: ['html', 'text'], description: 'Type of content to get', default: 'text', }, }, }, }, { name: 'hover', description: 'Hover over an element on the page', inputSchema: { type: 'object', properties: { selector: { type: 'string', description: 'CSS selector for the element to hover', }, }, required: ['selector'], }, }, { name: 'select', description: 'Select an option from a dropdown', inputSchema: { type: 'object', properties: { selector: { type: 'string', description: 'CSS selector for the select element', }, value: { type: 'string', description: 'Value to select', }, }, required: ['selector', 'value'], }, }, { name: 'get_console_logs', description: 'Get browser console logs', inputSchema: { type: 'object', properties: {}, }, }, { name: 'get_console_errors', description: 'Get browser console errors', inputSchema: { type: 'object', properties: {}, }, }, { name: 'get_network_logs', description: 'Get network activity logs', inputSchema: { type: 'object', properties: {}, }, }, { name: 'get_network_errors', description: 'Get network error logs', inputSchema: { type: 'object', properties: {}, }, }, { name: 'wipe_logs', description: 'Clear all stored logs from memory', inputSchema: { type: 'object', properties: {}, }, }, { name: 'get_selected_element', description: 'Get information about the currently selected element', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_accessibility_audit', description: 'Run an accessibility audit on the current page', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_performance_audit', description: 'Run a performance audit on the current page', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_seo_audit', description: 'Run an SEO audit on the current page', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_best_practices_audit', description: 'Run a best practices audit on the current page', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_nextjs_audit', description: 'Run a Next.js specific audit on the current page', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_debugger_mode', description: 'Run debugger mode to debug issues in the application', inputSchema: { type: 'object', properties: {}, }, }, { name: 'run_audit_mode', description: 'Run comprehensive audit mode for optimization', inputSchema: { type: 'object', properties: {}, }, }, { name: 'close_browser', description: 'Close the browser instance', inputSchema: { type: 'object', properties: {}, }, }, ],
