async navigate(url) { await this.ensureChromium(); await this.sendCDPCommand('Page.navigate', { url }); return { content: [{ type: 'text', text: `Successfully navigated to ${url}` }], }; } - index-browser-only.js:103-112 (schema)Input schema defining the required 'url' parameter as a string for the navigate tool.
inputSchema: { type: 'object', properties: { url: { type: 'string', description: 'The URL to navigate to', }, }, required: ['url'], }, - index-browser-only.js:100-113 (registration)Tool registration entry in the ListTools response, including name, description, and schema.
{ name: 'navigate', description: 'Navigate to a URL', inputSchema: { type: 'object', properties: { url: { type: 'string', description: 'The URL to navigate to', }, }, required: ['url'], }, }, - index-browser-only.js:178-180 (registration)Dispatch registration in the CallToolRequest handler switch statement that routes to the navigate handler.
case 'navigate': return await this.navigate(args.url); case 'get_content': - index-browser-only.js:209-243 (helper)Helper function to send Chrome DevTools Protocol (CDP) commands over WebSocket, used by the navigate handler.
async sendCDPCommand(method, params = {}) { return new Promise((resolve, reject) => { if (!wsConnection || wsConnection.readyState !== WebSocket.OPEN) { reject(new Error('No browser connection available')); return; } const commandId = Date.now(); const command = { id: commandId, method, params }; const timeout = setTimeout(() => { reject(new Error(`CDP command timeout: ${method}`)); }, 10000); const messageHandler = (data) => { try { const response = JSON.parse(data.toString()); if (response.id === commandId) { clearTimeout(timeout); wsConnection.off('message', messageHandler); if (response.error) { reject(new Error(`CDP error: ${response.error.message}`)); } else { resolve(response.result); } } } catch (error) { // Ignore parsing errors for non-matching messages } }; wsConnection.on('message', messageHandler); wsConnection.send(JSON.stringify(command)); }); }
